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.
