Using the SERIAL

The projector is equipped with an RS-232C standard serial terminal at the rear. It is therefore possible to connect it
to a computer for control.

Basic format

Transmission from the computer begins with STX, then the command, parameter and ETX are sent in this order.
Colon (:) is not required when transmitting the command which does not need a parameter.

Caution
• 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-L6600E /
PT-L6600EL 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.
