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 com-
mand, 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.
