General Product Information
Model FOSTC provides the most versatile connection possible between any asynchronous serial equipment using fiber optic cable. It allows any two pieces of asynchronous serial equipment to communicate full or half-duplex over two fibers at typical distances up to 2.5 miles. The converter can also be used to create a multi-drop master/slave configuration, allowing one serial device to talk to multiple slave devices around a fiber ring. RS-232, RS-422, or RS-485 data signals are supported. Different standards can be mixed and matched to allow RS-232 devices to connect to your RS-422 or RS-485 system. This means the FOSTC can replace converters and isolators when connecting remote devices, while providing the EMI/RFI and transient immunity of optical fiber. Supports both the Transmit and Receive data lines, and provides full hardware control of the RS-485 driver with B&B's automatic Send Data control circuit. All serial connections are provided on the same DB25 female connector, while the multimode fiber is connected via two ST connectors. Powered by 12 VDC at 140 mA max. A power supply is available.
