necessary.
Attention
No command can be sent or received for 60 seconds after the lamp starts lighting. Try sending any command after that
z
period has elapsed.
When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from the
z
projector before sending the next command.
Note
As with the PT-F300U/PT-FW300U and similar models, formats without an ID designation can also be used.
z
When the command can not be executed, the [ER401] status is sent from the projector to the personal computer.
z
When the wrong parameter is sent, the [ER402] status is sent from the projector to the personal computer.
z
Projector ID supported on the RS-232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z.
z
If a command is sent with a projector ID specified, the projector will return answer back only in the following cases:
z
If it coincides with the projector ID
If the ID specification is ALL and responding (ID ALL) is [ON]
The “STX” character code is 02 and the “ETX” character code is 03.
