• When sending several commands, be sure to wait for more than 0.5 seconds after receiving a
response from the projector, and then send the next command. When sending commands without
parameters, a colon (:) is not necessary.
parameters, a colon (:) is not necessary.
Attention
• If an unworkable command is received, the projector will send an “ER401” response to the computer.
• If an invalid command is received, the projector will send an “ER402” response to the computer.
• Projector ID supported on the RS-232C 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 an invalid command is received, the projector will send an “ER402” response to the computer.
• Projector ID supported on the RS-232C 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.
ID specification is ALL and VPS-SYSTEM is the master, or
ID specification is group and Group is the master.
• In the hexadecimal format, STX has the character code 02 and ETX the character code 03.
