Panasonic PT-L6500U Service Manual page 10

The data sent from the PC to the projector is transmitted in the format shown below.
Cautions:
- When it is unnecessary to designate an ID code, send the format
without the part to ID designate it. In this case, the projector sends
a call back to the PC irrespective of the projector ID setting.
- Add a parameter when the command function is required of it.
- If sending multiple commands, check that a call back has been
received from the projector for one command before sending the
next command.
Notes:
- When a command which does not require parameters is sent, the
colon (:) is not required.
- If a command is sent with a projector ID specified, the projector will
return call back only if the ID contained in the command matches
the projector ID or the projector ID is set to ALL.
- Projector ID supported on the RS-232C interface is 00 (ALL) to 99.
- When using control from REMOTE terminal, commands cannot be
received at SERIAL terminal.
