Multiple Serials Multiplexing Module
By using TDMA technology the serial port is extended to three (or more) two-way full duplex serial ports through real-time data multiplexing and demultiplexing. The main channel rate is above 115.2 Kbps and the sub-channel is9.6/19.2/38.4 Kbps adjustable. The physical interface supports RS232/485/422 and TTL.
