Computer control
A computer can be used to control the projector by connecting an RS-232C cable (null modem, cross type,
commercially available) to the projector. (See page 22 for connection.)
Communication conditions
Set the serial port settings of the computer as follows.
Signal format: Conforms to RS-232C standard. Parity bit: None
Baud rate*: 9,600 bps / 38,400bps / 115,200bps Stop bit: 1 bit
Data length: 8 bits Flow control: None
*Use the same settings for the projector and computer.
Basic format
Send commands from the computer in the following order: command, parameter, and return code. After
processing the command from the computer, the projector sends a response code to the computer.
Info
When controlling the projector using RS-232C commands from a computer, wait for at least 30 seconds
after the power has been turned on, and then transmit the commands.
After sending an input selection or picture adjustment command and then receiving an “OK” response
code, the projector may take some time to process the command. If a second command is sent while the
projector is still processing the fi rst command, you may receive an “ERR” response code. If this happens,
try resending the second command.
When more than one code is being sent, send each command only after the response code for the previ-
ous command from the projector is verifi ed.
“POWR????”, “TABN _ _ _ 1”, “TLPS _ _ _ 1”, “TPOW _ _ _ 1”, “TLPN _ _ _ 1”, “TLTT _ _ _ 1”,
“TLTM _ _ _ 1”, “TLTL _ _ _ 1”, “TNAM _ _ _ 1”, “MNRD _ _ _ 1”, “PJN0 _ _ _ 1”
−When the projector receives the special commands shown above:
* The on-screen display will not disappear.
