Point-To-Multipoint Address Coding 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 9.6~115.2 Kbps and the sub-channel is 1.2~38.4 Kbps. The physical interface supports RS232/485/422 and TTL.
