104 – ENGLISH

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.
Attention
No command can be sent or received for 10 to 60 seconds after the lamp starts lighting. Try sending any
command after that period has elapsed.
When transmitting multiple commands, be sure to wait until 0.5 of a second has elapsed after receiving the
response from the projector before sending the next command. When sending commands without parameters, a
colon (:) is not necessary.
Note
When the wrong command is sent, the “ER401” or “ER402” status is sent from the projector to the personal
computer.
Projector ID supported on the RS-232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z.
The “STX” character code is 02 and the “ETX” character code is 03.
If a command is sent with a projector ID specified, the projector will return answer back only in the following
cases:
If it coincides with the projector ID,
ID specification is ALL and VPS-SYSTEM is the master,
or ID specification is group and Group is the master.

Control commands

When controlling the projector from a computer, the following commands are available:
