Attention

Note

•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 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.

•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 RS232C 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.

•In the hexadecimal format, STX has the character code 02 and ETX the character code 03.
