- The serial port of node equipment can be selected from three working modes: RS232/RS422/RS485, and can adapt for a rate lower than 19.2kbps. Ethernet port can support 10M/100M, full-duplex/semi-duplex and adaptive modes, and accords with IEEE802.3 serial protocol;
- The node equipment can transmit E1 time-slot of serial port data or Ethernet data by DIP switch setting;
- The Ethernet port for IP upload of central convergence server accords with IEEE802.3 serial protocol;
- When central convergence server collects serial port data, the serial port data can adopt three methods to communicate with higher equipment: virtual serial port software, the controls developed by our company, Socket communication;
- When central convergence server collects serial port data, it can support three working modes: TCP server, TCP client and UPD. The working port, target IP and port are configurable;
- Central convergence server supports two network management modes: server configuration application provided by our company and web Server. It can also support remote configuration and remote online upgrade.
