Available for either Bus or String topologies, the TC2200 Multi-Drop Fiber Optic Modem links monitoring devices (RTUs or PLCs) fitted with RS-232 or RS-485 interfaces to a Host controller or CPU.
The electrical interface can be either RS-232 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 extreme temperature applications (-40°C to 70°C).
Each 850nm unit comes standard with two pair of fiber interfaces and either one RS-232 or RS-485 interface. Units with second RS-232 or RS-485 interfaces are optional. Standard 1300nm models have one fiber optic interface (second pair is optional) and one or two RS-232 or RS-485 interfaces.
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. 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.
Fiber optic connectors are ST, FC is optional. Electrical connectors are DB25 female. Power is 9 to 12 VDC or 115/230 VAC with an external power cube.
For ordering purposes, the TC2200 is the Master Unit; TC2201 is the Slave unit.

Typical Application (Application Questions)
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.
