I am using ABB Protonic PS2 Controller shown in the attached Image. I connected cross over serial cable DB 9 Pin on our computer and other side on controller(Image attached). While i trying to read the data from controller to my computer its showing its not communicating(Image attached). Where i made mistake. Can you tell me the solution for it.
I don't know this device, but I had a look at the interface description document. It has a section for troubleshooting communication issues. I propose you go through those and check each topic mentioned.
