The RS-232 Interface is an adapter for low voltage controls used on Da-Lite motorized screens. This RS-232 Interface allows wired remote control of a screen. The Ethernet Adapter for the RS-232 Interface allows the freedom of wired remote control of a screen through a TCP/IP connection. The Ethernet Adapter is classified as a serial device server, which means that it makes available to client computers the Da-Lite screen as a serial device (enabled by the RS-232 Interface). The Ethernet Adapter supports the suite of RS-232 commands developed under the RS-232 Interface, and allows those commands to be issued by an Ethernet enabled computer or third-party controller.
