[Vision 120 comms to Epson LX-350 printer over RS232]

Thanks a lot guys, turns out it was a poor cable connection.... anti-climactic I know...

I am going RJ11 to RJ45/Ethernet to DB25... I was treating the RJ11 cable as a straight through, but it was in fact a crossover which I didn't realise.

I don't like the application to begin with, sending an RS232 signal to an old dot matrix printer is a little archaic for me but I got it going so thats the important part!

Thanks a lot for the feedback everyone.

Thanks Aus, I will try with Hercules and see how I make out.

I'm also suspicious of the wiring, but that part shouldn't be too diffuicult to troubleshoot. I've ordered a proper rj45 to db25 connector that I hope should help so I will update with my progress.

Thanks, Adam

Good morning. I am trying to print messages using the send protocol from a Vision120 to an epson lx350 dot matrix printer. I have the Com Init command and the protocol config command setup.

I have it wired up correctly (I believe) from the RJ11 to RJ45 to the DB25 adapter to plug into the printer.

This system has worked in the past, I inherited the project from a customer who's controls engineer left, and now I'm stuck on getting the printer to work. I have downloaded the program and HMI config and they are working fine.

Does anyone have experience in something similar to this? Is there something on the printer side I have to do?

Let's assume that I have the communication wiring 100% correct. I still have to verify that again in the morning.

Thanks a lot,
