RS-232 commands

IMPORTANT:

 When formatting commands sent from a control system or 

computer, enclose commands in parentheses “(“ and “)”.  When entering 

custom commands into Scheduled Tasks in the projector’s web interface, 

enclose commands in less than/greater than symbols “<” and “>” instead.

Communication Configuration
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:

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  

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 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 

entering the next command.
