RS-232 terminal Product Interface specifications

Communication configuration

To control the projector from an LCD control panel, connect an RS-232 cable to

the serial control connector on the projector and set your computer’s serial port

settings to match this communication configuration:

Command format

All commands consist of 3 alpha characters followed by a request, all enclosed in

“greater than” and “less than” signs. The request can be a read request (indicated

by a “?”) or a write request (indicated by 1 to 4 ASCII digits).

A read request format: <AAA?> where

< starts the command

AAA denotes the command

? denotes the read request

> ends the command

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. 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

Refer to the support section of our website for detailed information on the Prod-

uct Interface formats.
