InFocus-IN146-RS232
IN146 Control commands
IMPORTANT: When formatting commands sent from a control system or computer, enclose commands in parentheses “(“ and “)”. When entering custom commands into Scheduled Tasks in the projector’s web interface, enclose commands in less than/greater than symbols “<” and “>” instead.
Serial Communication Configuration
Visit our website for additional RS‐232 settings and information.
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.

Network Communication Configuration
For network control, you can access the projector through Port 23 (Telnet).
We use the same control codes on serial as we do over the network. InFocus network control uses the Telnet packet structure.
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:

Command
(BRT?)
(VOL?)
(LMP?)
Response
(0‐100, 50)
(0‐100, 50)
(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 exception is the Power command, where 0 is off and 1 is on.
To assure the projector can process a command, wait 5 seconds before entering the next command. 10 seconds on power up or power down.

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.
