Ethernet to serial converters allow the MediaMaster System to control and manage display assets anywhere in the school’s data network. The single-port version is particularly useful for controlling a flat panel display in a classroom. It is compact and light, so it may be securely adhered to the back of the display. Although it may be possible to connect the device under control and converter directly to each other, we recommend use of a short cable between the two to avoid undue stress on the connectors. The device converts between 10/100Base-T Ethernet and RS-232, RS-422 or RS-485 serial at up to 230 kbit/sec. The serial side uses a DB-9M port. The converter gets its power from a typical wall-mounted power supply, which is included.
