Basic format
Transmission from the computer starts with STX, then the ID, command, parameter, and ETX are sent in this
order. Add parameters according to the details of control.
STX A D I1 I2 ; C1 C2 C3 : P1 P2 Pn ETX
ID designate
ZZ, 01 to 06
Start (1 byte)
2 ID characters (2 bytes)
Semi-colon(1 byte)
3 command characters (3 bytes)
Colon(1 byte)
Parameter (undened length) End (1 byte)
(2 bytes)
Basic format (with sub command)
S1 S2 S3 S4 S5 E P1 P2 P3 P4 P5 P6
Same as the basic format
Sub command (5 bytes)
Operation (1 byte)*
1
“=” (Set to the value specied by the parameter)
Parameter (6 bytes)*
1
Symbol “+” or “
-
” (1 byte) and set value
or adjustment value (5 bytes)
STX A D I1 I2 ; C1 C2 C3 : ETX
*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 luminous 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 ID transmission in RS-232C supports ZZ (ALL) and 01 to 06.
f If a command is sent with a specied ID, a response will be sent to the computer only in the following cases.
- It matches the projector ID
- When [PROJECTOR ID] (x page 87) on the projector is [ALL]
f STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
