Infocus LP860 Specification Guide

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: 

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:

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.
