Black BNC Adapter (SMA M)
Black SMA-Male (Yaesu etc) to BNC-Female Low Loss RF Adapter
The BNC (Bayonet Neill–Concelman) connector is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter-turn of the coupling nut. The connector has a 50 Ω impedance.
SMA (SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. The connector has a 50 Ω impedance.


I need help with wiring my home media system so I can see on the TV what Iâ€™m going to record on my Panasonic DVR. My setup is:
- Denon AVR-3805 receiver
- Panasonic DMR-EZ485V VCR/DVD recorder combo
- Comcast DX3400 DVR Cablebox for HD TV signal source
- Tivo Series 2 non-digital L DVR
- Maxent 1080i HD TV
- Single room 5.1 speakers
Before my older model Panasonic DVR died, I had it wired just fine. But now I either forgot how I had wired it or the newer Panasonic behaves differently, or itâ€™s defective. Panasonic customer service is singularly unhelpful. They could only verify that if the RF cable and TV were hooked directly into the EZ485V and I could change channels, all was well. They donâ€™t understand receivers at all, nor do they appreciate that I donâ€™t even want to change channels on the EZ485V, that I want to record time-shifted programs from the Comcast boxâ€™s so its internal HD doesnâ€™t fill up before Iâ€™ve had a chance to watch them.
I want to get the highest quality video and audio signal that I can, component video or HDMI and digital audio if possible, and be able to see the signal that Iâ€™m recording on the EZ485V. Can anyone help me? I can list the wiring that I’m currently using, if that helps.

The invention is based on a priority application EP 05290259.0 which is hereby incorporated by reference.
The invention relates to a method for estimating at least one optical link parameter.
For performance monitoring of 10 Gb/s (future 40 Gb/s) transmission systems, it is mandatory to obtain a reliable estimate of the status of optical transmission links for preemptive fault detection for network management or network control. This status can be described by optical link parameters being characteristic of the distortion of an optical signal transmitted through the optical fiber link, such as chromatic dispersion (CD), polarization mode dispersion (PMD), self-phase modulation (SPM), etc.
There have been proposed many costly solutions for performance monitoring of optical links, including optical measurement techniques as well as techniques which use additional modulation tones (not in the standard). At the ECOC 2004, M. Wrage and B. Spinnler have proposed a method of distortion identification by analyzing equalizer coefficients (FFE tap settings) of a finite impulse response (FIR) equalizer in the paper “Distortion Identification in WDM Networks by Analysis of Electrical Equalizer Coefficients”. The solution proposed in this paper is based on the equaliser setting of a FFE, which is used for all signal bit patterns. Due to the limited parameter set (taps) it works only for a limited dispersion range or fails if mixed distortions are present (e.g. PMD and CD).
It is the object of the invention to obtain a reliable estimate of the status of an optical transmission link by determining estimates of optical link parameters being characteristic for distortion induced in the optical link.
This object is achieved by a method for estimating at least one optical link parameter using a Viterbi equalizer generating averaged values of signal amplitudes of a distorted optical signal transmitted through an optical link for a set of decided bit patterns, the method comprising the following steps: (a) forming a first parameter set characteristic of a distorted signal sequence using the averaged values for a given sequence of bit patterns, (b) comparing the first parameter set to a plurality of reference parameter sets characteristic for reference signal sequences of the same sequence of bit patterns, each of the reference parameter sets having a known value of the at least one optical link parameter, and (c) selecting the reference parameter set with the closest correlation to the first parameter set, the known value of the at least one optical link parameter of the selected reference parameter set being used as an estimate for the at least one optical link parameter.
The inventive method uses a Viterbi equalizer which already sorts the received signal (samples of it) according to the bit pattern. Each bit pattern consists of a sequence of subsequent decided bits being correlated by inter-symbol interference (ISI), the ISI being characteristic for the distortion of the optical link. Therefore, much more parameters as in the state of the art can be used to quantify and identify different distortions (=dispersions).
For a given sequence of bit patterns, a first parameter set consisting of a sequence of averaged values characteristic for the unknown optical link parameter (distortion) is generated. This parameter set is compared to reference parameter sets consisting each of a sequence of averaged values with a known value of the optical link parameter. The reference sequence having the parameter set which is closest to the first parameter set is chosen as an estimate for the optical link parameter. It is evident that the precision with which the optical link parameter is estimated depends on the number of reference parameter sets used. If two reference parameter sets have about the same (closest) correlation to the first parameter set, the estimate of the optical link parameter is accomplished by interpolating between the known values of the two reference parameter sets.
In a preferred variant, the averaged values of the signal amplitudes are derived from histograms of signal amplitudes generated by the Viterbi equalizer. For enabling the decisions of Viterbi equalizers (channel modeling) and avoiding erroneous decisions it is well-known to use a monitoring device generating statistical data about the signal transmitted through the optical link. In such a device, a histogram of a probability distribution of signal amplitudes of an optical signal transmitted through the optical fiber link is generated. Each peak of the probability distribution, which is about equal to the mean value, is characteristic for the received signal amplitude belonging to one of the bit patterns. It might be appropriate to characterize a bit pattern by a signal amplitude at or close to the temporal center position of the bit pattern.
In a further preferred variant, steps (a) to (c) are carried through for a second parameter set using further statistical data about the signal amplitudes derived from the histograms. The histograms may serve to determine more statistical data than just the mean value for each bit pattern.
In a further variant, the further statistical data comprises the variance of the signal amplitudes. The mean value of the signal amplitude may be used in conjunction with the variance of the signal amplitude for determining certain optical link parameters such as the optical signal to noise ratio (OSNR).
In a preferred variant, the comparison in step (c) is carried through by a maximum likelihood estimation, in particular by calculating a minimum square error. In this way, an easy comparison of the reference parameter sets with the first parameter set is provided.
In a highly preferred variant, the at least one optical link parameter is selected from the group consisting of chromatic dispersion (CD), polarization mode dispersion (PMD), self-phase modulation (SPM), and optical signal to noise ratio (OSNR). These (and other) properties of the optical fiber link may be advantageously determined by the inventive method.
In a further variant, step (a) is preceded by a reference parameter set generating step, generating a reference value for each bit pattern and for each reference parameter set. The reference value may be the averaged value, the variance, etc. of the signal amplitude.
In a highly preferred variant, the given sequence of bit patterns is derived from a sequence of transmitted bits. In this way, an on-line determination of optical link parameters for a transmitted signal is possible.
In yet another variant, three subsequent decided bits are used to form a bit pattern. The three subsequent bits are correlated through inter-symbol interference (ISI), i.e. the transmitted bit in the center of the three subsequent bits is influenced by the bit transmitted directly before and the bit transmitted directly after the bit in the center. The ISI is due to signal distortion.
The invention is also realized in a computer program product comprising a software or a hardware implementing the method as described above. The computer program product may be implemented as a hardware in a DSP-ASIC or as a software in a processor reading the histogram data of the Viterbi-ASICs. The dispersion values may then be made available to the network management or the control plane of the optical network.
Further advantages can be extracted from the description and the enclosed drawing. The features mentioned above and below can be used in accordance with the invention either individually or collectively in any combination. The embodiments mentioned are not to be understood as an exhaustive enumeration but rather have exemplary character for the description of the invention.
The invention is shown in the drawing.
The technique explained below is based on the existence of a Viterbi equalizer 1 as shown in
Depending on the subsequent bits appearing at the output of the Viterbi core 3, a shift register 4 distributes the input to the Viterbi core 3 to one of the output channels of a multiplexer 5. The outputs are fed into a histogram generator 6. Commonly the signal at the input of the multiplexer 5 is analog-to-digital converted (not shown in the FIGURE) and the histogram generator 6 comprises digital registers. However, it is also possible to use an analog multiplexer as an alternative solution. The process described above will be explained in greater detail below:
The shift register 4 contains a first, second and third bit ijk and is connected to the output of the Viterbi core 3. The second bit j is the decided bit for a given sampling time (t), the first bit i is the decided bit at a previous sampling time (t−1), and the third bit k is the decided bit at a subsequent sampling time (t+1). The contents of the shift register 4 are shifted to the left after each time step.
The reason why three bits ijk are registered in the shift register 4 is that the correlation length of the inter-symbol interference (ISI) is one bit, i.e. only the subsequent, third bit k and the previous, first bit i have an influence on the analog value of the optical signal measured for the second bit j. There are eight possible states of the shift register 4, each one defining a bit pattern. The first bit pattern a is identified with the three-bit state ijk=000, the second bit pattern b is identified with the three-bit state ijk=001, etc.
The shift register 4 is connected to the multiplexer 5 whose input is connected to the input of the Viterbi core 3. The analog value of the signal at the input of the Viterbi Core 3 is therefore delivered as an input to the multiplexer 5 which selects one out of its eight possible output channels in dependence of the state of the shift register 4. Thus, the analog values for each of the eight decided bit patterns are delivered in separate channels to the histogram generator 6.
The histogram generator 6 uses the analog values or the digitized analog values measured for each of the bit patterns at the entrance to the Viterbi core 3 to generate a probability density function pdf(a), pdf(b) etc. for each of the bit patterns (channel model). An output of the histogram generator 6 is used as a feedback signal to the Viterbi core 3, adapting the branch metric unit in dependence of the statistical data generated in the histogram generator 6. From the probability density functions pdf(a), pdf(b), . . . the mean values M(a), M(b), . . . of signal amplitudes of the analog signal can be derived for each bit pattern a, b, etc. The mean values M(a), M(b), . . . measured in
It is practical to evaluate the signal amplitude only at the sampling time of the actual transmitted bit j. However, it is also possible to determine the value of the signal amplitude over a short time interval before and after the decision time of the second bit j, the time interval being much shorter than the overall duration of the three-bit sequence ijk. The time average over this short time interval may be taken in the histogram generator 6 before the statistical evaluation is carried through.
The statistical information about the optical signal in the histogram generator 6 is dependent on the distortion of the optical link 2, as the ISI is distortion-dependent. Consequently, the data being present in the histogram generator 6 can be used to calculate optical link parameters such as chromatic dispersion (CD), polarization mode dispersion (PMD) etc., with the method described below.
For this method to work, it is necessary that the averaged values M(a), M(b) etc. for each of the eight bit patterns are determined in the Viterbi equalizer 1. These values being known, a sequence of bit patterns, e.g. abdf, is defined in a first step 7 of the method and a sequence of mean values M(a), M(b), M(d), M(g) is generated from this sequence, so that a first parameter set S(M(a), M(b), M(d), M(g)) is formed.
In a second step 8, the first parameter set S is compared to a plurality of reference parameter sets R. The reference parameter sets R consist of a sequence of averaged values of the analog signal with known values of the distortion parameters to be estimated, in the present case CD and PMD. The first/second reference parameter set R1/R2 corresponds to a first/second value CD1/CD2 of chromatic dispersion and a first/second value PMD1/PMD2 of polarization modulation dispersion. Of course, it is possible for the reference parameter sets R to differ only in one optical link parameter, such that in the above case, the values of polarization mode dispersion are equal for all of the reference sequences R whereas the CD values are not.
In a third step 9, the reference sequence with the closest correlation to the first parameter set S is chosen. The correlation is defined in the sense of a maximum-likelihood correlation, being evaluated e.g. by calculating the minimum square error between the parameter set S and the parameter sets R, i.e. min(S−R)2. The reference parameter set with the closest correlation to the first parameter set S is determined and the corresponding distortion values CD, PMD define the estimated link parameters for chromatic dispersion and polarization mode dispersion, respectively.
Because of the use of averaged values a noise-free (but still distorted) analog sequence is reproduced. This analog sequence may or may not have been transmitted through the optical link 2. It is sufficient that the sequence of bit patterns is significant for the analog signal. However, the sequence of bit patterns it is chosen preferably in such a way that it has a significance for the transmitted signal. Especially, it is possible to derive the sequence of bit patterns from a sequence of decided bits transmitted through the optical link 2, as is described below.
As an example for the connection between bit sequences and bit patterns, it is supposed that for a given time step a bit sequence consisting of three subsequent bits a=000 corresponding to the first bit pattern a is present in the shift register 4. In the following time step, a new decided bit “1” is present at the output of the Viterbi core 3. Consequently, the shift register and adopts the state ijk=001 corresponding to the second bit pattern b. In the following time step, a new decided bit “1” is present at the output of the Viterbi core 3, leading to a state ijk=011 of the shift register 4, corresponding to the fourth bit pattern d. If the decided bit of the subsequent time step is “0”, the state of the shift register 4 is ijk=110, corresponding to the seventh bit pattern g.
In this way, the sequence of decided bits transmitted through the optical fiber link 2 consisting of six subsequent bits 000110 gives rise to the sequence of four bit patterns abdg. It is thus possible to carry through the three steps 7, 8, and 9 with a sequence of bit patterns being derived from the sequence of transmitted bits. The length of the sequence of bit patterns may be chosen to be four, as above, though it is also possible to use a sequence consisting of more or less bit patterns.
The method described above may be easily modified by using additional statistical data from the histogram generator 6, e.g. the variance of the amplitudes of the bit patterns a, b, etc. Thus, a second, third etc. parameter set can be generated for each sequence of bit patterns. The correlation of these parameter sets and the reference parameter sets for these additional parameters can be calculated as described above. As a result, optical link parameters with greater accuracy can be obtained. In this way, it is also possible to estimate the signal-to-noise ratio. The variances, which can be extracted from the different histograms, are directly linked to the optical signal to noise ratio (OSNR). The lower the OSNR, the more noise and the bigger are the variances. The OSNR values can be determined by comparing the histogram variances with the variances of reference patterns R with a known OSNR, or can directly be calculated from the histograms using theoretical approaches.
The reference parameter sets R can be obtained before the first step 7 by generating a look-up table in which an averaged value of the analog signal is stored for each value of the at least one optical link parameter and for each bit pattern. These averaged values have either been measured or obtained by numerical simulation for each distortion parameter separately or for mixed distortions (i.e. CD and PMD). It is also possible that the reference parameter sets are calculated on-line in a processor while performing the method as described above. The method described above may be implemented as hardware or software as part of a Viterbi equalizer control.
In summary, when a Viterbi equalizer is present in an optical receiver, the above method for the determination of distortion parameters can be easily implemented almost without additional cost as a software in the Viterbi equalizer. As Viterbi equalizers generally adapt themselves to the incoming signals in the range of milliseconds, a millisecond speed for performance monitoring of optical links can be reached. Furthermore, the method described above uses more parameters than the state of the art and consequently has the potential to be more precise.

G.652.D fiber is the most current subcategory of G.652 fiber. What’s the difference between legacy G.652 fiber and G.652.D fiber? Compared with G.652.A fiber and G.652.B fiber, G.652.D fiber eliminates the water peak for full spectrum operation. Conventional G.652.A and G.652.B are not optimized for wavelength-division multiplexing (WDN) applications due to the high attenuation in the E-band region (1360-1460 nm), which is the water peak band. The G.652.D fiber has been developed to specifically reduce the water peak at the 1383nm wavelength range. So G.652.D fiber optic cable can be used in the wavelength regions 1310 nm and 1550 nm, and supporting Coarse WDM (CWDM) transmission.
Although both G.652.C and G.652.D offer low water peak at 1383 nm, the G.652.D fiber specification shows superior PMD performance than G.652.C fiber, which is 0.2 ps/sqrt(km) in G.652.D vs. 0.5 ps/sqrt(km) in G.652.C.

Several years ago, it was recognized that there are three broad factors that when combined drive exponential bandwidth growth:
Bandwidth Explosion = Increased number of users * Increased access rates and methods * Increased services
This simple equation highlights three separate trends that must be continuously monitored in order to ensure that Ethernet continues to evolve at a pace to meet the demands of a given application space. Many are familiar with Ethernet’s dominance in the enterprise/campus and data center spaces. The reality, however, is that many application spaces are seeking to leverage Ethernet, and Ethernet is evolving to provide these target application spaces with specific solutions. Therefore, it is important to apply this equation to a target application space to understand its trajectory and subsequent networking needs.
One of these application spaces is mobile networks, where Ethernet-based solutions are being leveraged throughout the mobile network for front, middle, and backhaul of mobile traffic. The bandwidth demands of the mobile network application space, in particular China, was used as justification for the start of the IEEE 802.3 Beyond 10km Optical PHY Study Group. As shown in Figure 1, China is forecasted to experience a bandwidth explosion in its mobile networks that by 2020 will result in it having nearly 40% more data per month than the nearest compared global region.
Figure 1 - Mobile Network Bandwidth Trends (2017)
A recent presentation into the IEEE 802.3 New Ethernet Applications Bandwidth Assessment Project provided data that enabled further insight into the challenge for China’s mobile networks and provides a real-world example of the noted bandwidth explosion equation.
#1: Number of 4G Users
Today, China has 1.1 billion 4G users. In 2011, the penetration was only at approximately 10%, but by June of 2018 had grown to 73.5%.
#2: Increased access rates
From Q4 2016 to Q2 2018, the average download rate of 4G users has grown by 70%, growing from 11.93 Mb/s to 20.22 Mb/s.
#3: Traffic consumption per household
Monthly data mobile traffic per month grew from 0.2 GB to 4.2 GB.
The data provided by these three trends helps to explain the mobile network traffic growth highlighted in Figure 1. It should also provide clear direction to the implication of deployment of 5G throughout mobile networks, which are already being stressed by 4G deployment.
John D' Ambrosia,
Networked cars could provide additional stress onto mobile networks. In 2019 it is forecasted that there will be 117 million cars produced globally. Over the past decade there has been significant investment by the Ethernet community in developing a family of solutions over a single-twisted pair for use in automobiles. Standards for 100 Mb/s Ethernet and Gigabit Ethernet have already been completed - with new standards for 10 Mb/s, 2.5 Gb/s, 5 Gb/s, and 10 Gb/s Ethernet underway as we speak.
As these vehicles become increasingly networked and connected to the cloud with their own growth in access rates - they will present yet another significant pressure that mobile networks will be called upon to service. As an emerging space, it is unclear yet what applications will be introduced, and as a result, the potential bandwidth demand of connected cars, especially for autonomous driving, could be staggering, especially in a highly congested metro area.
Such trends can only mean one thing to the Ethernet community - it too will need to continue to evolve - providing new solutions that will support the future bandwidth demands of mobile networks. There are a number of efforts underway already within the IEEE 802.3 Ethernet working group that are directly applicable to them:
IEEE P802.3cn 50 Gb/s, 200 Gb/s, and 400 Gb/s over Single-Mode Fiber - this fast-tracked project will leverage the PAM4 technology developed to support links at these rates currently up to 10km and build upon them to expand their reach to 40km.
IEEE P802.3cp Bidirectional 10 Gb/s, 25 Gb/s, and 50 Gb/s Optical Access PHYs - this effort will develop bidirectional optical access PHYs for 10GbE, 25GbE, and 50GbE for point-to-point applications where the availability of fibers is limited. Wireless infrastructure is one of the key application spaces that this effort targets.
IEEE P802.3ct 100 Gb/s and 400 Gb/s over DWDM Systems - this effort will see Ethernet evolve to support reaches up to 80km over a DWDM system. While the main drivers for this effort have been Multi-Service Operators (MSO) and Data Center Interconnect (DCI), it is easy to see how these solutions could be utilized for future mobile network aggregation and core backhaul.
It should be clear to all that the overall trend in all of this is that there is a growing diversity of applications that are calling upon the Ethernet community to provide them with their solutions for today and tomorrow. It has never been truer when one says “Ethernet Everywhere!”.


Tag archives for Microcontroller regulated power supply
In any electronic products or projects there is always a source of power for the system to work. This is called a power supply. The source of this power can come from different sources like the mains AC voltage, a battery or even from a renewable power source like a solar panel wind turbine or fuel cell to name just a few. The most common source of power is usually the mains AC, with this power, we need a transformer to convert the 220V 50Hz mains or the 120V 60Hz if you are living in the United States of America to a lower voltage required by the electronic circuit, this can be typically between 6V and 12V when 5V regulated DC is needed. In this article we are going to design a simple 5V DC power supply that can be used to power your Microcontroler projects using the 7805 voltage regulator.

A Bluetooth speakerphone is a hands-free phone device that allows a person to take calls without the use of a headset. There are models that plug into a wall through an AC adapter, and ones that run on a battery and can be used wirelessly. Bluetooth speakerphones in vehicles have become increasingly popular since many US states banned the use of cellphones while driving.
Some individuals wear headsets or earpieces that connect to their Bluetooth, but those who do not like the feeling of those accessories may prefer a speakerphone. Those designed for the car typically clip onto the visor over the driver’s seat, and can be recharged through the cigarette lighter.
The speakers are fairly compact and all of the components are usually integrated into a single housing, but some models may have a speaker which extends through a small arm. Most models have buttons for basic functions such as making and ending phone calls, redialing a number, or adjusting the volume.
Depending on the affiliated cell phone, a Bluetooth speaker can support conference calls and is capable of voice recognition — those that can do the latter are the safest for use in the car since they can be used 100 percent hands-free from start to finish. People who make a lot of calls while driving will appreciate the echo-cancelling technology found in various Bluetooth speakerphones.
The speakerphone connects to the user’s cell phone utilizing Bluetooth technology, which uses radiofrequency waves to pair devices without the use of wires or cables. Once the devices have been linked, the user can adjust their call system so that all incoming calls are directed to the speakerphone anytime it is near the cell phone. More advanced models can double as media players, automatically switching from music playback to an incoming phone call.
Though usually associated with smartphones, Bluetooth technology is capable of so much more. If one doesn’t have their USB cable with them but needs to transfer files from one device to another — like a smartphone to a tablet, or a tablet to an external drive — information can be sent via Bluetooth, expelling the need of USB ports and various cables altogether. So long as two Bluetooth enabled devices are within range of one another, they can send and receive files regardless if they are on different networks.
Bluetooth also allows for a Wi-Fi sharing technique called tethering. If one device is connected to the Internet and the other is not, Bluetooth can tether the two devices together so each can employ Wi-Fi. Bluetooth tethering even consumes less battery power than connecting a device directly to the local Wi-Fi network. Bluetooth users have the option to create a Personal Area Network (PAN). The PAN operates within a 30-foot range and can support up to seven Bluetooth-enabled devices, each of which can communicate with one another, share data, and use the same Wi-Fi connection.
As stated previously, Bluetooth compatible devices are not limited strictly to cellphone use; there are a magnitude of items available on the market designed to mitigate hassle. Wireless keyboards, for example, allow the user to sit anywhere leisurely, within the connectivity rage, without being tied down to a desk. If you work in large office, a Bluetooth enabled printer can easily connect to your computer without any hardware, software, or Wi-Fi.
Bluetooth enabled gaming consoles help create a more engaging and active experience, without the fear of ripping a wired console from its hub. These are especially useful in motion-sensitive games, like Wii sports games, where the player does a lot of movement and can’t afford to be tied down by wires.
It is not associated with it today, but the name Bluetooth actually has violent roots. It was the nickname of Danish King Harald Blatand. King Blatand violently brought together areas of Denmark, Norway, and Sweden in the mid-900s. As for the nickname, some historians conclude it came from the king’s love of blueberries. Others say it sprung from the fact that the warrior’s teeth would turn blue after eating the flesh of his defeated enemies.
A Swedish man named Sven Mattisson developed the form of Bluetooth technology that we use today. In 1995 Mattisson’s Ph.D. thesis at the California Institute of Technology on circuit simulators gained the attention of Ericsson Mobile Communications. The company brought Mattisson in to help develop a technology that would allow mobile phones to connect through short-range radio links, rather than cables. This technology was called Multi-Communicator Links (MC Links). By 1997, Intel’s head of technological development Jim Kardach partnered with Mattisson to explore more devices that could be connected using MC Links.
Mattisson and Kardach decided that their technology would be most useful as an open standard in the frequency range of 2.45 GHz. The duo invited Nokia, IBM, and Toshiba to organize their own company-based development groups to work on the project. In 1998, the first MC Links technology became available for public consumption, under the name of Bluetooth. Consumers were initially unimpressed by Bluetooth’s slow download speeds — a mere 721 kilobits per second — and it took Mattisson and Kardach nearly a decade to release a version capable of the 20 megabits per second we’re accustomed to today.

The circuits component of NetBox deals with the management of long-haul Internet and private transit links and providers.
A provider is any entity which provides some form of connectivity. While this obviously includes carriers which offer Internet and private transit service, it might also include Internet exchange (IX) points and even organizations with whom you peer directly.
Each provider may be assigned an autonomous system number (ASN), an account number, and contact information.
A circuit represents a single physical data link connecting two endpoints. Each circuit belongs to a provider and must be assigned a circuit ID which is unique to that provider.
Circuits are classified by type. For example, you might define circuit types for:
- Internet transit
- Out-of-band connectivity
- Private backhaul
Circuit types are fully customizable.
A circuit may have one or two terminations, annotated as the "A" and "Z" sides of the circuit. A single-termination circuit can be used when you don't know (or care) about the far end of a circuit (for example, an Internet access circuit which connects to a transit provider). A dual-termination circuit is useful for tracking circuits which connect two sites.
Each circuit termination is tied to a site, and optionally to a specific device and interface within that site. Each termination can be assigned a separate downstream and upstream speed independent from one another. Fields are also available to track cross-connect and patch panel details.
A circuit represents a physical link, and cannot have more than two endpoints. When modeling a multi-point topology, each leg of the topology must be defined as a discrete circuit.

Rumours had it that Xiaomi Mi Mix 4 will be released by next month. According to Wang Teng, Redmi was the first to use the 64MP sensor and Xiaomi will most likely use the 108MP sensor which was launched a few days back on its imminent device like the upcoming Xiaomi Mi Mix 4 smartphone.
The Mi Mix 4 will come with Snapdragon 855+ SoC and according to rumours, the phone will support an on-screen camera and a 100W fast charge technology.
Series of new phones will hit the market between August to September: Vivo Nex 3, iQOO Pro 5G and more. Therefore, Xiaomi may not take too long to release the Mi Mix 4 as to keep up with the competition.


The existing pair of Explora decoders are connected with a local HB cable connected to the RF ports?
So, what you will have to do is install a diplexer behind the Primary Explora to inject HB onto the SLNB cabling so that the other HD 5 decoder can receive HB via the SLNB. That avoids the need for extending the HB connection via another cable.
It may not work however because there are reports that the Explora 1 is not really able to provide sufficient HB signal strength via an SLNB.
The HD decoder must be connected to a unicable port as well, NOT to a universal port on the SLNB.

I do have 2 x Dstv explora 1s in my lounge and 1 HD 5 in another room with a smart LNB.
2 csbles come from the smart LNB to the 2 exploras and one from smart LNB to other room on the HD 5.
How and ehere wil I connect a duplexir?
There are no way for extra cables in my wall.
It's a partially oddly labelled diplexer due to poor tech English from the Chinese source.
(EDIT: If the Aerial King label is attached its English words are correct and standard, as detailed below.)
Here's the correct usage from Aerial King for normal and reverse (when RF-cabling HB (HeartBeat) distribution needs to be created) diplexer use;
ANT (S1) - connects to the RF In or Out port (depending on user's needs)
I/O (PX) - connects to the LNB's cable coming from the dish
SAT (S2) - connects to the LNB input port
ANT (S1) - connects to the RF coaxial cable you will be routing
I/O (PX) - connects to the LNB input port
SAT (S2) - connects to the LNB's cable coming from the dish

Ardupilot autopilot application that we successfully compiled on Linux board Beagle Bone Blue supports a wide variety of sensors from many different manufacturers. Being an open source application, it is supported by developers all across the world and its scope of sensor integration is ever increasing. The application supports multiple communication protocols such as I2C, SPI, UART (or Serial) and CANBUS (in particular UAVCAN) protocols. Beagle Bone Blue provides hardware support for all these communication protocols. However, in the course of making our drones, I have utilized UART and I2C communication protocols only.
A brief introduction to all the supported protocols is as under:
An important concept adopted by Ardupilot autopilot application as part of its sensor driver architecture is the front-end and back-end split mode of implementation. The main Ardupilot code only calls into the front end libraries i.e front end sensor drivers. When the system starts up, the front-end creates one or multiple instances of back-ends based either on
Pointers to each back-end is maintained by front-end. It is held within an array named drivers and incase of user settable parameters; it is always held within front-end.
Understanding the back-end working of code which runs in background. Sensor raw data is collected and converted to standard units and then the values are held in buffers within drivers. Incase of copters, the vehicle main code thread runs regularly at 400Hz. It accesses latest available data through methods in drivers’ front-end. For example , the AHRS/EKF pulls the latest accelerometer, gyroscope and compass information from the sensor drivers’ front-ends. The running of background threads ensure that the high-rate communication with the sensor as it does not affect the main loop’s performance. Serial (i.e UART) interfaced sensor codes are safe to run in the main thread as the underlying serial driver collects data in the background and includes a buffer. It does not affect the main vehicle code. Hence, I have preferred UART as the interface of choice for most sensors.
GPS with Compass features
The connectivity diagram for GPS (with Compass) to Beagle Bone Blue as Fight Controller Unit (FCU)
GPS with compass is the bare minimum sensor required for reliable and stable flight operation of a drone. Now for a drone to be manually controller we need a controller. Incase of drones we have a Radio Controller (RC) Transmitter available in various channel configurations to control the drone operations manually from ground station. The RC transmitter is binded to a RC receiver on radio link. The RC receiver present onboard the drone is connected to Flight Controller over wired link running the option of multiple communication protocols.
RC Receiver protocols enable communication with the Flight Controller Unit (FCU). Some communication protocols are proprietary and some are non-proprietary. The list of protocols are PWM (universal), PPM or CPPM (universal), SBUS (Futaba, Frsky), IBUS (Flysky), XBUS (JR), MSP (Multiwii), CRSF (TBS Crossfire), SPEKTRUM1024 (Spektrum DSM2), SPEKTRUM2048 (Spektrum DSMX), FPort (Frsky). I am using the SBUS protocol for the choice of RC receiver i.e X8R. It is connected to SBUS interface on Beagle Bone Blue incase of all three drones i.e X-Type, V-Type and Hexacopter. It requires The 5V and 1-2 Amp power is provided separately through DC convertor and the overall connectivity diagram in Figure 3.10. SBUS is a bus protocol utilized by receivers in order to send commands. Its a digital loss-less bus architecture protocol which uses only 3 wires (signal, power, ground) for multiple channels. Compared to commonly used PPM which is a signal in time domain, SBUS protocols is digital and requires a serial port on the flight controller i.e UART. A single serial line supports upto 16 channels with each receiving a unique command. This SBUS protocol uses an inverted serial logic. It has a baud rate of 100000, 8 data bits, even parity, and 2 stop bits. The packet size of SBUS is 25 bytes and contains:
Byte: SBUS header, 0x0F
Byte[1 -22]: 16 servo channels, 11 bits each
Bit 7: channel 17 (0x80)
Bit 6: channel 18 (0x40)
Bit 5: frame lost (0x20)
Bit 4: failsafe activated (0x10)
Byte: SBUS footer
RC Transmitter protocols enable communication with the RC Receiver onboard drone over radio link. Its communication protocol for radio transmitter and receiver (two way link). Some communication protocols are proprietary and some are non-proprietary. The list of protocols are ACCST (Frsky), ACCESS (Frsky), DSM (Spektrum), DSM2 (Spektrum), DSMX (Spektrum), AFHDS (Flysky), AFHDS 2A (Flysky), A-FHSS (Hitec), FASST (Futaba), Hi-Sky (Deviation / Devo), Frsky’s TX Protocols. Frsky has two TX protocols, ACCST and ACCESS. I have utilized Frsky RC transmitter.
A2 RP LIDAR Model: A2M3, A2M4 was integrated with the Hexacopter. Its a 360-degree 2D laser scanner (LIDAR) with 6 meter range. It supports up to 4000 samples of laser ranging per second with high rotation speed. It performs 360-degree 2D to generate 2D point cloud data which is used for mapping, localization and object/environment modeling. The scanning frequency is 10hz (600rpm) with best resolution of 0.9-Degrees. It adopts low-cost laser triangulation measurement system. It emits modulated infrared laser, during its ranging process. The signal and the laser signal is reflected by the object in its field of view. The reflected signal is sampled by vision acquisition system and then the embedded DSP starts processing the sample data with distance and angle between object and RPLIDAR through communication interface. The motor system, drives the range scanner core which rotates clockwise to perform the 360-degree scan.
The light source of LIDAR system is a low power infrared laser. It drives the system by using modulated pulse. The duration of laser light emission is very short and complies with Class I laser safety standard as per product datasheet. The sample point data contains the information as shown in picture below:
LIDAR Connectivity diagram
The LIDAR on drone has to be mounted horizontally. It could be on the top or bottom. The black cable must point towards the rear of the vehicle. The field of view of the sensor must remain unobstructed which includes the , drone frame parts like legs, GPS mast or any other component.
The APM power Module is connected to ADC port of the Beagle Bone Blue. The power module sits between Input from battery and power distribution for drone components with XT60 Connectors, Male and Female connectors on respective sides. The APM module provides clean power from battery and also provide voltage measurement between 6-28V (upto 6s battery) and 90 Amps of current. The signal output for voltage measurement is 5V while ADC input range is 1.8V max. Thus, we use 1k and 2k resistors to keep signal voltage less than 1.8V. The pinout and connection details are in the connectivity diagram below:-
Electronic Speed Control (ESC) and Motors
The connectivity of Electronic Speed Control with motors and Flight Controller Unit i.e Beagle Bone Blue is illustrated in picture below.
We have utilized the Brushless DC motors procured off the shelf. The motor and ESC make and model details are available in figure above. The BLDC motor meets the requirement for a mechanical commutator as required in drone application by reversing the motor set-up. As a result, the windings become the stator and the permanent magnets therefore become part of the rotor. These BLDC motors are powered by MOSFET bridge controllers popularly known as ESCs using pulse-width modulation (PWM). The windings are commutated in a controlled sequence. As a result of that, it produces a rotating magnetic field which “drags” the rotor around and consequently drives the attached load which in our case our propellers.

Apple might be planning to transition its iOS devices to USB-C connectivity later this year. There are rumors about Apple shipping a Lightning -> USB-C cable and a new 18W charger, rendered here. This means that the new iPhone buyers will be using USB-C for charging with a cable. This will also provide the ability to use the fast charging offered by the Type-C without the need for additional accessories.
According to a Digitimes report, Apple might add Type-C port to the iPhones itself. This will be a huge change and will bring an end to the Apple proprietary lightning cable. It will come to an end after being the primary option to charge the iOS devices for past seven years.
The iPhones started coming with the lightning ports in 2012 with the introduction of the iPhone 5. Prior to that, all the iPhones came with iPod’s 30-pin dock connector. The introduction of lightning cable was a controversial decision and a large ecosystem of docks and accessories became incompatible with the newer devices.
The shift from lightning to Type-C wouldn’t be as tough as that from 30 pin connector. This is because of the number of accessories that depend on lightning is far less than the 30 pin connector. This along with the fact that a lot of accessories made for Type-C were being used with dongles already will mean the change will be more than welcome.
Apple has already started to use Type on the Macs and it will bring the Apple ecosystem even closer. There is big potential for USB-C on iPad too, enabling it to become more of a fully-fledged PC replacement.
As of now, all the three upcoming iPhones and the iPads will come bundled with an 18W USB-C charger. The customers can now charge their devices at maximum speed without having to buy additional accessories.

As the world becomes more and more digital, machines for manufacturing have had to keep up with new technology. Machines need to communicate data between other machines in a process. In the past, this was done through physical wire connections from one machine to the next, then it transferred to several machines being connected through a physical wire source. Now as data becomes more valuable as manufacturing becomes more automated and less hand checked, digital connections have become more necessary and competent.
New interfaces and connections such as HMI, clouds, and new PC-based systems allow for faster and higher quality connections. As these connections have improved, the key has been to create more open systems. Cords that originally connected between two machines would not allow for ease in converting to new machines and setting up group systems. Open systems allow multiple machines to interact and are more customizable to the manufacturer's needs. These systems work most optimally when IT is combined with automation to provide data while producing efficiently.
There are 4 main reasons to integrate IT with machine controls:
- PCs allow for integration
- PLC data storage and retrieval
- Improved data
- Remote access to information
PCs and Integration
These two are connected because integrating new components and testing devices into manufacturing as it becomes more automated, is important. The ability to connect and change out components is key in keeping up with technology and with PC systems, this can be changed and done much more efficiently. Using older technology and machines do not allow for easy retrofitting, but by keeping up with IT equipment, new models may be able to be retrofitted.
Adding PLCs to the manufacturing process has improved the quality and speed that automated machines can track data. PLCs can receive, store, then send data out to continually check for errors in machines. This can save on costs of fixing problems with machines before they break completely and can also help companies see if the machines are functioning at optimal efficiency.
With PLCs bringing in and sending so much data, IT is necessary to combine with this device to refine the data and analyze it. Other software programs can be paired with PLCs to analyze data for efficiency, estimated time of production or shipping time lines. Because the data comes in so fast and in bulk, these programs need to keep up with nearly real time in evaluating the data. This is where IT can contribute to manufacturing more now than ever.
Manufacturing has advanced to be able to be located where the resources are if that is more efficient, and as companies grow, manufacturing may take place in a different location than the corporate office. For these reasons, remote access to controls and data files is essential in growing a company. IT can set up and incorporate software and programs that allow information from a plant to be accessed via online program or even on a mobile device app. The benefits of this are numerous, but the important factor is that data is available readily for managers, which improves efficiency in communication.
Overall benefits of combining IT and automation:
- Easier integration of improvements and data collectors
- Improved data analysis and tracking
- Remote access to information and data
- Improves efficiency of manufacturing
- Keeps a company up to date with technology
While there's an ongoing debate between PLC and PC based controls, chances are that your process will benefit from integrating industrial data collection with IT. However you choose to collect production data, specifying and programming machine controls like a PLC panel can be a challenge without expert technical support.
