Status report & Alarm system

This is an analog (4 signal channels max.) and digital (16 signal channels max.) data transfer system before sending through only one signal line pair to the destination, which saves huge wiring costs. Then the signals will be decoded and status sent from the source will be displayed, including the ability to turn on alarm signals at both the source and destination. The system is designed to connect 1:1 or many to one (bus topology), self-detected if the signal line is disconnected. Moreover, the system has the ability to show multiple alarm statuses to users.
