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.

The main unit is equipped with SERIAL terminals located in its terminal section on the side, and this terminal is

compliant with RS232C. Also a serial output terminal is provided to enable plural projector control.

• 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 sending several commands, be sure to wait for a response from the projector before sending the

next command. When sending commands without parameters, a colon (:) is not necessary.

Attention

• If a wrong command is received, the projector will send an “ER401” command to the computer.

• Projector ID supported on the RS232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z.

• 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.
