To start with, I will let everyone know what I have, and what I'm trying to do, then my problem. 1: Windows XP pro SP3 on a Dell Latitude D610 2: RSLinx Classic 2.59 3: 1203-USB Flashed with the 1.004 firmware 4: Connected Comnponents workbench 2.0 So here is what I've done already. I installed the connected components workbench 2.0 which gave me all of the above. Then I plugged the 1203 into my USB port, and installed the drivers that I downloaded from AB. After that, I setup the driver in RSLinx exactly to the instructions listed in the manual. When I go to RS Who, I get nothing for a drive. So I looked around and see there was a firmware update. So I updated to the 1.004 firmware using the hyperterminal method. That worked perfect. No errors. Tried again, and it still didn't work. I know I'm on Com 4, because when I go to control panel, it tells me so. I used hyper terminal to change the drive to a master instead of AUTO, and did a reset, and that didn't work. I have even went to the extreme of reinstalling windows, and trying different options in the OS... No firewall, etc... Nothing. IT did connect one time, and now I cannot figure out what it did to duplicate that. When I upgraded the firmware, I ran the controlflash install program which put a bunch of folders under 0001. Then in hyperterminal I selected 0001/0078/2500 and the boot one first, then the combo one second. I'm not sure what all the other folders are for. Is this correct? Any ideas? Thanks in advance Pat [/INST] If I understand correctly, you can communicate via Hyper terminal, but not RSLinx. Is the main diamond shaped light on the 1203-USB blinking green? Does the drive have any other comm modules (e.g. 22-comm-E)? Is it part of a Multi-Drive setup? What are the settings you used with RSLinx? (Please list all items, or provide a screen shot) Generally, it should be: - RS-232 DF1 Devices - Device: 1770-KF2/1785-KE/SCANport - Baud Rate: 115200 - Error Checking: CRC Other options: - Is Hyper terminal closed? (RSLinx must be able to access the comm port) - In the RSWho window, right click on the driver and get what the properties are. - Is RSLinx browsing? (animated icon on driver; “Autobrowse” checked) \\n </s>
