The Lantronix MSS family of Universal Thin Servers allows you to network-enable a variety of serial devices that were not originally designed to be networked. Typically, an MSS achieves this by providing one or more serial ports on one end and an Ethernet I/O port on the other end. ??The MSS1 is available in two configurations. The MSS1-T provides 10BASE-T Ethernet networking. The MSS1-T2 provides 10BASE-T and 10BASE-2 Ethernet interfaces, but only one interface can be used at a time. Both MSS1 models have a DB25 serial port for serial connections.
