How do I change my product sources using RS-232 command codes when viewing images in Split Screen mode?

• 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.

  1. Click Start or , and select Programs or All Programs, then Accessories and Communications.
