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 seconds 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
If the ID specification is ALL and responding (ID ALL) is on
If the ID specification is Group and responding (ID Group) is on
