A write request example:
(AAA####) where
(starts the command
AAA denotes the command
#### denotes the value to be written
(leading zeros not necessary)
) ends the command
Some commands have ranges, while others are absolute. If a number greater
than the maximum range is received, it is automatically set to the maximum
number for that function. If a command is received that is not understood, a "?" is
returned. With absolute settings, "0" is off, 1-9999 is on. The one exception is the
Power command, where 0 is off and 1 is on.
To change the value, add "+" before the value to be written to increase the value
or "-" before the value to decrease the value.
To assure the projector can process a command, wait 3 seconds before entering
the next command.
Write Command Examples
Function Command Response
Brightness (BRT140) Sets the brightness to
140
Power (PWR0) Turns power off
Power (PWR1) Turns power on
Error Conditions
Not all commands are supported for all projectors. If an unsupported command
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. Therefore, 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.
