|Drop and Insert Multi-Drop Fiber modem
Bus or String Fiber Optic Modem
Each unit comes with one or two pairs of fiber interfaces and RS-232 or RS-422/RS-485.
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.
Available for either Bus or String topologies, the TC2200 Multi-Drop Fiber Optic Modem links monitoring devices (RTUs or PLCs) fitted with RS-232, RS-422 or RS-485 interfaces to a Host controller or CPU.
The electrical interface can be either RS-232, RS-422 or RS-485. The RS-485 electrical port can be multi-dropped. Asynchronous data rates can be up to 38.4 Kbps. A special version (TC2200T) is available for hardened temperature applications (-40°C to 70°C).
Each unit comes with one or two pairs of fiber interfaces and either two channel RS-232 or one channel RS-422/RS-485. The second RS-232 channel can be used for data, RTS/CTS handshaking signals or as a telephone extension with the Model TC1900 "Quick-Talk" Telephone Extenders.
For applications requiring maximum reliability, the TC2200 is also available in a dual Master "Fault Tolerant" version, providing a Back-up Master unit. In the event of cable breakage or a defective Remote unit, the backup Master will start polling the Remote units from the opposite direction. The primary and secondary Master units can be located anywhere on the fiber bus network. Remote units can be daisy-chained.
The "Anti-Streaming" capability is standard. Anti-streaming prevents a single node failure (e.g. "babbling") from bringing down the entire network. 16 Diagnostic LEDs are provided for "Tx," "Rx," "Fault" and "Power".
The TC2200 is compatible with all popular types and sizes of fiber optic cable and is available multimode (850/1300nm) or single mode (1300/1550nm). Fiber optic connectors are ST or FC. Electrical connectors are DB25 female. Power is 12VDC; optional 24VDC, -48VDC, or 115/230VAC with an external power cube.
For ordering purposes, the TC2200 is the Master Unit; TC2201 is the Slave unit.
