Hi All
Hoping someone can help out here with a communication issue with my SLC 5/03 processor's ch 0 serial connection.
I have a feeling that while experimenting with RSView just through my PC and serial cable, I have changed the configuration of channel 0 or something along those lines?
I have tried everything found and recommended on this forum and others on the web with no luck. I have tried the factory reset by disconnecting battery and shorting VBB- GND and using hyperterminal to confirm PC and processor serial ports. I couldn't get a response from my processor. I can confirm that my PC com port and null modem cable is ok (by simply linking pins 2-3 and typing into hyperterminal) My processor has a flashing FLT light with a slow flashing DH485 green light, which I understand is normal for a clean processor. Only thing is no matter what I do I cannot communicate with RSLinx. I have tried auto config with no luck and have setup port with 19200 and 1200 with no luck. I have been online with the processor in the past and gave up for a while but need to communicate now. I know and have tried with all the correct settings in RSLinx.
I am yet to try a 1747-PIC cable to try and establish comms though channel 1, and am waiting on the correct cable.
Is it possible that the serial port on my processor has failed and defaulted to ch 1 comms?
Any advice would be greatly appreciated..
Thanks
