Multi-Drop Fiber Optic Modem
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.
