IN42 / C445
RS-232C communication
Communication Configuration
To control this projector via RS-232, connect a null modem cable and set the control system serial port
settings to match the following communication configuration:
RS-232 Port Settings
Setting Value
Bits per second 19,200
Data bits 8
Parity None
Stop bits 1
Flow control None
Emulation VT100
Command Format
All commands consist of 3 alpha characters followed by a request, all enclosed in parentheses. The request
can be a read request (indicated by a “?”) or a write request (indicated by 1 to 4 ASCII digits).
A read request example:
(AAA?) where
(starts the command
AAA denotes the command
? denotes the read request)
ends the command
A read command returns the range and the current setting, for example:
Read Command Examples
Function Command Response
Brightness (BRT?) (96-160, 128)
Volume (VOL?) (0-32, 0)
Lamp Hours (LMP?) (0-32766, 42)
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 excep-tion is the Power
command, where 0 is off and 1 is on.
To assure the projector can process a command, wait 3 seconds before enter-ing the next command.

IN42 / C445
Write Command Examples
Function Command Response
Brightness (BRT140) Sets the brightness to 140
Power (PWRO) Turns power off
Power (PWRI) 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 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.
