Connecting to a room controller

If your projector has a serial port, you can connect the projector to a room controller using a serial (RS-232) cable. After you program the room controller using the following commands, you can use the room controller to operate the projector and other components of your installation.

Serial connections

The serial port on the projector uses a female, mini-DIN 6, RS-232 connector:

•Pin 3: data sent to the projector (RX)

•Pin 5: data sent from the projector (TX)

•Pins 1, 4, and 6: not connected

•Pin 2: ground (GND)

•7: metal frame (shroud)

The room controller must use the following serial (RS-232) settings:

•9600 baud

•1 start bit + 8 data bits (D0=LSB, D7=MSB) + 1 stop bit

•No parity

•Full duplex communication channels (no flow control)

•No handshaking
