Connecting Communications - Christie J Series User Manual

2.2.9 Connecting Communications

Remote Keypads
To control the projector, direct the IR remote towards the display screen or the IR sensors on the projector.
Alternatively, connect a wired (tethered) version of the remote to the XLR connector labeled as
input panel. NOTE: The response to a wired keypad must also be enabled in the Communications menu.
As an alternative to the keypad or remote, you may wish to communicate with the projector using a PC or other
controller. Such a device sends commands and receives feedback via serial links (RS-232 and RS-422RS-422), or
Ethernet communications to the projector, refer to the Serial Command document provided in the Dealer Section of the
Christie Website, PN 020-100224-XX.
1.) Serial Port Connections
RS-232 and RS-422, serial ports available on the projector: You can connect a device with a serial interface,
such as a computer to either of these connectors (not both) and control the projector remotely by entering
specific serial communication commands, see the Serial Command document provided in the Dealer Section
of the Christie Website, PN 020-100224-XX.
2.) Connecting RS-232
Two nine-pin D-sub connectors, labeled RS-232 IN and RS-232 OUT on the input panel, are dedicated to
serial communication, see
controlling source, such as a personal computer to the RS-232 IN connector. Set the projector baud rate to
match that of the computer. See
3.) Connecting RS-422
To control the projector with a computer or other controlling device with RS-422 capability, connect a RS-422
serial communication cable between the controlling device and the RS-422 port on the projector, see
20. RS-422 is better suited than RS-232 for serial communication over distances greater than 50 feet.
