First post here, but I will try to be thorough.
I am trying to display alarm messages and variable data from a Modicon Quantum PLC. We had a 2 line ASCII display that quit working, and apparently nobody makes a replacement. We are trying an AB INVIEW 2706-P22R display. Communication is serial RS232. All messages are pre-programmed in the INVIEW, and triggered by an ASCII string from the Quantum.
We are using a Gould J892 2 port ASCII module in a Modicon 984 rack, as a remote rack to the Quantum PLC. We have confirmed using Hyperterminal that the proper ASCII string (^T1^M) is being sent to the INVIEW, and cabling appears to be correct as we can trigger a message using the INVIEW software across the cable. There is no COMM light on the INVIEW to indicate if communications are working. All tech-support(AB and Modicon) insist everything should be working.
Any help would be greatly appreciated.
