RS-232 Command
Serial Interface RS-232 Command
This controller supports projectors with a RS-232 serial interface. There are two types of serial commands:
•  Operation command: Available menu options are INPUT, PICTURE, LAMP, ALIGNMENT, CONTROL, 
SERVICE, and OTHERS.
•  Simulated IR remote controller commands: Controls projector with serial command analog IR remote con-
troller and its control keys.
Communication Parameter Setup
You can use the serial control command to input commands for projector control or retrieve its operational 
data through Windows client terminal software, e.g. Hyper Terminal, with ASCII characters. You need to set 
up the following communication parameters in advance:

The transmission performance would vary with the matching length of RS-232 cable and transmission speed. Please select proper 
transmission from the OSD menu.
