RS232 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 format (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:

Function	Command	Response
Brightness	(BRT?)	(96-160, 128)
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 in 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.
