Christie D20WU-HS RS232 Control

Hi,

I have a BrightSign XT1144 and a Christie D20WU-HS projector. The serial output of the BrightSign is connected to the serial input on the projector.All settings are correct in the player and on the projector, baud rate, start / stop bit. 

The command for Power on the projector is (PWR 1) and off (PWR 0).At the first image in my presentation, I send a serial string (EOL) with the command (PWR 1)But now the problem, nothing happens. The projector does not respond to any commands.

Does anyone know what I could do wrong? I checked all cables with the correct pin assignment.

List with Commands:

Thanks in advance!

    Have you tried to troubleshoot using a PC with a serial terminal application?

    Also, make sure that your RS232 cable is wired so Tx pin at the player's side, is wired to the Rx pin at the projector side.

    TX and RX reversed and it works perfectly now. Stupid I didn't try that.

    Thanks anyway!
