Hello there, we've a pci parallel card of yours and whenever we install the drivers it crashes our windows at startup. What exactly appears is a blue screen of death, with the error code STOP: 0x0000007e The only work-around we have found so far, in order to avoid this issue and use our computer and the card, is to disable the card before pc shut down, then turn it on and activate the card. This way it works like a charm, no problem. Obviously, this is not correct for an hardware to work, so if you could give us a tip on how it could be fixed and work properly. We are at your service for any further info, and we hope you can help us out! Thank you very much.
I have purchased the serial card, I installed it and installed the drivers, but I cannot find anywhere how to change the mode to RS485. I need to use this board for ModBus Communication, and it will only work with RS485. I have used Pins 1,2 and 5 where 1 is Data -, 2 is Data +, and 5 is GND. I connect it to the modbus cards but I get no Communication.
