Mixed Serial Network (Rs232 And Rs422) - Christie Entero RPMSP–LED01 Installation Manual

Mixed Serial Network (RS232 and RS422)

RS422 serial communication is better over long distances than RS232 communication. Use the RS422 port only
if your device has the capability. Always read the equipment literature before connecting.
NOTICE: Connecting to the RS422 port with incompatible equipment, including the wrong type of serial cable,
can damage the projector.
In the illustrated RS–422 network, the controller can communicate with the first projector and the command can
be relayed to each serially connected projector.
1. Connect the controller to 1 projector using a RS422 serial cable between the PC and the RS422 IN port on
the electronics module.
2. Connect an RS232 serial cable between the RS232 OUT connector of the first projector's electronics
module and the RS232 IN connector of the next projector's electronics module. Connect the remaining
projectors using RS232 cables. RS232 communication cables must be good of quality and no more than 25
ft (7.6 m) in length.
3. Set the serial options in Configuration > Communications.
4. Set Configuration > Communications > Network Routing to RS232 and RS422 Joined.
