Serial connector

The serial connector complies with RS-232C. To control the projector from a personal computer, com-
mands must be input through communication software, based on the format and satisfying the commu-
nication conditions shown below.

Pin assignments and signal names

Communication conditions (factory setting)

Basic format

Transmission from the computer begins with STX, then the ID, command, parameter, and ETX are sent
in this order. Add parameters according to the details of control.

CAUTIION
It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 seconds, then
try sending or receiving again. When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector
before sending the next command. Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for
command response to 10 seconds or more.

NOTE:
If a wrong command is received, the projector will send an ER401 command to the computer.
When sending commands without parameters, a colon (:) is not necessary.

* Effective when connected to a PC having proper functions.
