2.4Connecting Communications

IR Remote f

As an alternative to the projector’s 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 (RS232 and RS422), Ethernet or GPIO communications to the projector, all described below.

As desired, direct the projector’s IR remote towards the display screen or the projector’s IR sensors. Alternatively, connect a wired (tethered) version of the remote to the RCA jack labeled REMOTE on the projector’s input panel. Note that response to a wired keypad must also be enabled in the Communications menu—see 3.6 - Adjusting System Parameters and Advanced Controls for more information.

Serial Port Connections f There are two types of serial ports available on the projector: RS232 and RS422. 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.

Connecting RS-232

The two nine-pin DIN connectors labeled RS232 IN and RS232 OUT on the input panel are dedicated to serial communication. Using the appropriate serial communication cables (see Appendix C) connect the controlling source, such as a personal computer to the RS232 IN connector. Then set the baud rate to match that of the computer. Refer to Section 3 for details on changing the projector’s baud rate.

Connecting RS-422

If you wish to control the projector with a computer and or other controlling device with RS-422 capability, connect a RS-422 serial communication cable between the computer and the RS-422 port on the projector. RS-422 is better suited for serial communication over long distances then is RS-232 communication.

Use the RS-422 port only if your device had RS-422 capability – always consult the literature provided with your equipment before connecting. Connecting to the RS- 422 port with incompatible equipment could damage your projector.
