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

AAAdenotes the command ? denotes the read request ) ends the command

A read command returns the range and the current setting, for example:

A write request example:

####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 3 seconds before enter- ing the next command.
