•On commencement of lamp lighting, commands cannot be sent or responses received for approximately 10 seconds. Be sure to send any commands and receive responses 10 seconds. (Applies to the PT-L6600U / PT-L6600UL only)

•When transmitting several commands, wait for a response from the projector before sending the next command. When sending commands without parameters, a colon is not necessary.

•When it is unnecessary to designate an ID code, send the format without the part to ID designate it.

Note

•If a wrong command is received, the projector sends ER401 back to the computer.

•When using control from the remote terminal, commands cannot be received at the serial terminal.

•Projector ID supported on the RS-232C interface is 0 (ALL) to 99.

•The remote control ID is set from 0 to 3. If a command is sent with a projector ID specified, the projector will return answer back only if the ID contained in the command matches the projector ID or the projector ID is set to ALL.
