Write Command Examples

Function	Command	Response
Brightness	(BRT140)	Sets the brightness to 140
Power	(PWRO)	Turns power off
Power	(PWR1)	Turns power on

Error Conditions

Not all commands are supported for all projectors. If an unsupported com- mand is issued, the command will be ignored. If a command is received that is not understood, a ‘?’ character will be returned indicating the command was not understood.

Limitations

The projector cannot respond to commands coming in at a high-rate. There- fore, a delay must occur between commands to ensure that the command gets properly executed. To assure the projector can process a command, wait 3 seconds before entering the next command.

The Step column refers to increasing or decreasing the menu bar position since the On-screen Display is not an exact match of values. For example, Step 2 changes the data by 2 through the CLI (Command Line Interface). The menu bar is up (or down) by 1.
