Add parameters according to the details of control. STX A D I 1 I 2 ; C1 C2 C3 : P1 P2 Pn ETX (2 bytes) Two ID characters (2 bytes) Semicolon (1 byte) Colon (1 byte) Start ZZ, 1 to 64 and 0A to 0Z 3 command (1 byte) ID designate characters (3 bytes) End (1 byte) Parameter (undefined length) Attention • 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. Note • 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. 39
