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 standard serial (RS-232) cable:
• Pin 2: data sent to the projector (RxD)
• Pin 3: data sent from the projector (TxD)
• Pin 5: ground
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
Examples of room controller commands
In the following examples, “<CR>” and “<LF>” represent a carriage return and line feed,
respectively.
Commands are sent to the projector as "requests" which consist of an asterisk (*) prefix, the
command name, any needed parameter, and a carriage return <CR> as a terminator:
* command = parameter <CR>
Requests can contain only ASCII alphanumeric characters. Blanks (spaces) are allowed, except
within keywords and numbers. Line feeds <LF> are ignored.
