3Communication

3.1 Command Format

Implement commands that are to be sent to the projector in the following manner.

[STX] COM1:P1P2P3P4 [ETX]

Head identifier -Send [STX] (Hex’02’or Ctrl B for ASCII), at the beginning of the command string.

This will allow the projector to receive the following command.

Command (COM1) –The Command is written by 3 characters. The Letters are capitalized. . See

the command tables in Section 5 for details.

Parameter (P1P2P3P4) -The Parameter data is required by certain commands. The parameter

data information can be 1 to 4 bytes in length, which is dependant on the individual commands. If no

parameter is required by the specific command, then this information does not need to be

transmitted. See the command tables in Section 5 for details.

End identifier -Send [ETX] (Hex’03’or CTRL C for ASCII) at the end of command string.

Command and its parameter should be separated by a ”:” colon (Hex’3A’). When a command that

does not require parameters is sent, then the separating colon can be eliminated.

Example of a command string

[STX] IIS:VID[ETX]
