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.
