Da-Lite NET-100 serial switch box

The NET-100 is a Serial to Ethernet adapter to the SCB-100 Serial Control Board for Da-Lite motorized screens and projector lifts. This Ethernet adapter allows remote control of a screen or lift through a TCP/IP connection.
The NET-100 is classified as a serial device server, which by definition means that it makes available to client computers the Da-Lite screen or lift as a serial device (enabled by the SCB-100). The NET-100 supports the suite of RS-232 commands developed under the SCB-100, and allows those commands to be issued by an Ethernet enabled computer or third party controller.
