Q:
How do I change the projector sources using RS-232 command codes when viewing images in Split Screen mode?

A:
Use the following RS-232 command codes to switch the projector sources when viewing images in Split Screen mode.

RS-232 command code Description
SPS 03 xx Source change for the left screen. Replace xx with the value from the ESC/VP21 RS-232 manual. For example, SPS 03 42 changes the left screen to the S-Video source.
SPS 04 xx Source change for the right screen. Replace xx with the value from the ESC/VP21 RS-232 manual. For example, SPS 04 B0 changes the right screen to the BNC source.

These commands can be added to a Crestron or AMX command string. They can also be used in a Windows HyperTerminal session when a computer is connected directly to the projector's DB9 serial port with a NULL serial cable or a NULL serial adapter attached to a straight-through PC serial cable. If you are using a laptop with only USB ports, you will need to use a USB-to-DB9 serial adapter with an assigned com driver. Select the com driver to use in HyperTerminal.
