Hi, I am not totally new to this forum, but have been away for awhile. The RC forums were instrumental a couple of years back in my being able to successfully complete a project with PEP1, TSU9600 and two RFX9600.
As you shall be able to read further on, for the last few days a have been baffled with what essentially boils down to: What is occurring when a ASKII command controlled equipment reacts as expected through Windows Hyper Terminal and has no reaction at all when access through the PEP2/TSU9800 panel and a RFX9600 serial port?
I am using ProntoEditPro2 and have currently updated all the Pronto components to: PEP2.4, TUS9800 panel firmware 7.3.3 and RFX9600 extender firmware 1.4.7.
Problem: While RS232 ASKII commands are sent through Windows HyperTerminal and equipment has been verified to respond correctly , when the same exact command and syntax is inserted into the PEP2 ASCII function command section and downloaded to the panel, the command does blink the correct the RFX9600 extender RS232 serial port led, but the equipment fails to react. As to discard any straight to cross wiring issues between pins 2 & 3, additional iterations of tests are performed with a null modem connector inserted and removed, but to no avail. Subsequent changes and test are made to the ASKII command syntax in the PEP2, by adding \r, \n, etc., and we still get no reaction from the equipment we intend to control. Leaving everything "as is", except for removing the RS232 cable from the extender serial port and connecting it to the PC serial port, the exact same ASKII command is typed and sent through Windows HyperTerminal, with or without \r and the equipment is confirmed to react correctly. We also made conversions of the commands from ASKII to HEX and inserted the commands into PEP2, downloaded them to the panel, but with the same failed results. Thus we have covered and verified to have the correct software and firmware updates, the RS232 cable wiring, baud rate and other serial port parameters, but cannot get the equipment to react when connected to Pronto TSU9800 / RFX9600 combo, but it will invariably react correctly when connected to a PC with the exact same cables, connectors and commands, via Windows HyperTerminal.
In addition we have made tests, tying together pins 4-6 and pins 1-7-8, but still to no avail. The manufacturer's literature (Polycom HDX8000) states that only pins 2,3,and 5 are required. We also connected the RS232 serial port of the RFX9600 to the PC and on Windows Hyper Terminal observed that the command's ASKII characters read exactly the same as was input to PEP2 program, except when we would addition to the command, control characters like \r, which seem to have no effect and to do not reproduce as characters on the Hyper Terminal window. Some test that were performed with commands that had been converted to HEX, when transmitted to the PC and observed through Hyper Terminal, would be shown as the original ASKII characters, but if the HEX converted command contain control characters, then the command would show with the correct ASKII and a few gibberish characters.
I am required to finish this project in the next two or three days, so I am in a dire predicament and have run out options on what to try next, any and all help will be greatly appreciated.
