Multi-Drop Fiber Optic Modem (Bus/String: RS232/422/485)

The TC2200 Multi-Drop Modem maximizes the reliability of communication links in Ring or String topology industrial fiber optic networks. A “dual Master” extreme fault tolerant version that can poll remote units from the opposite direction in the event of a link or device failure is optional.

The TC2200 supports RS232, RS422 or RS485 interfaces and is often used to interconnect RTUs, PLCs & IEDs in Utility, SCADA, Traffic Control & Industrial Process Control networks.

Each unit comes with one or two pairs of fiber interfaces and either 2 RS232 channels or one RS485/RS422 channel. The second RS232 channel can be used for data, RTS/CTS handshaking signals or as a telephone extension with the TC1900 RS232 Telephone Extender. It supports asynchronous data rates up to 38.4 Kbps and offers a ruggedized, substation hardened (-40°C to 80°C) version.

Renowned for its high reliability, the TC2200 Multi-Drop Modem is ideal for Bus or String communication links in SCADA, Traffic Control, Industrial Process Control and security networks. It is frequently used to interconnect Remote Terminal Units (RTUs) or Programmable Logic Controllers (PLCs) in Utility substation SCADA Networks.
