Basic format
Transmission from the computer starts with STX, then the command, parameter, and ETX are sent in this order. Add
parameters according to the details of control.
STX C1 C2 C3 : P1 P2 Pn ETX
Start (1 byte)
3 command characters (3 bytes)
Colon(1 byte)
Parameter (undened length) End (1 byte)
Basic format (with sub command)
S1 S2 S3 S4 S5 E P1 P2 P3 P4 P5 P6
STX C1 C2 C3 : ETX
Same as basic format
Sub command (5 bytes)
Operation (1 byte)
“=” (Value specied using parameter is set)
Parameter (6 bytes)*
1
Symbol “+” or “
-
” (1 byte) and set value or ad-
justment value (5 bytes)
*1 When transmitting a command which does not need a parameter, the operation (E) and parameter are not necessary.
Attention
f If a command is transmitted after the lamp starts illuminating, there may be a delay in response or the command may not be
executed. Try sending or receiving any command after 60 seconds.
f 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 transmitting a command which does not need a parameter, a colon (:) is
not necessary.
Note
f If a command cannot be executed, the “ER401” response is sent from the projector to the computer.
f If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer.
f STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
