Hi,
Extron devices are always labeled as follows:
Rx: Extron device receives RS232
Tx: Extron device sends RS232
DTP Crosspoint supports RS232 and IR extension over DTP. Please ensure that you are connected to the RS232 pins, not the IR.
DTP Rx has 2 outputs with 5 pin captive screw: Audio and RS232/IR. Please check and ensure that the projector is connected to the RS232 port, no the audio...
You can check Extron communication sheets for wiring between Rx and NEC.
Best regards
P.S.: DTP Crosspoint support "Serial over Ethernet", saving COM ports on the control system.
Change from "Captive Screw" to "Ethernet insertion" in PCS and adjust the baud parameters.
In the control system use a TCP Client, point it to the IP address of the DTP Crosspoint, use the port that is displayed in PCS (2001 is input 1, 2002 input, etc). The DTP Rx will output the RS232 to the projector.
