A computer can be used to control the projector by connecting an RS-232C serial control
came (cross type, commercially available) to the projector. (See page 24 for connection.)

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" re-
sponse code, the projector may take some time to process the command. If a second command is
sent while the projector is still processing the first 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
previous command from the projector is verified.
"POWR????" "TABN ___ 1" "TLPS ___ I" "TPOW ___ 1" "TLPN ___ I" "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.
* The "Auto Power Off" timer will not be reset.
- The special commands are available for applications that require continuous polling.
