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:

Bits per second

19,200

Data bits

8

Parity

None

Stop bits

1

Flow control

None

Emulation

VT100

     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:

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.
