    RS-232 Interface Selection

    Good Afternoon:
    We are assisting a customer with AV integration and they wanted to tie in the Lutron lighting system. Our communications protocol is via RS232 and looking at their system, I believe they would need a QSE-CI-NWK-E or GRX-CI-RS232 however I am not sure which device if either of those is appropriate to interface with there dimmer. Currently they have the Lutron gp24-1204ml-20 and a GP3-1204M-20. I didn't get the model of the control panel itself but I can if it helps. I know typically the interface then is low voltage MUX to the dimmer. Could someone assist me with the proper interface selection? Thank you!

    In order to apply the lighting system integration you would have to use GRX-CI-RS232. That would allow the dimmer interface to function properly.
