High Speed RS-232, 422, 485 Fiber Modem

Use Fiber Optics to Carry Your RS-232/422/485 Signal Up to 2.5 Miles at 460Kbps The Model ADP3134 provides the most versatile connection possible between any asynchronous serial equipment using Fiber Optic cable. The ADP3134 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 ADP3134 can replace converters and isolators when connecting remote devices, while providing the EMI/RFI and transient immunity of optical fiber. The ADP3134 supports both the Transmit and Receive data lines. All serial connections are provided on the same DB-25 female connector, while the multimode fiber is connected via two ST connectors. The unit is powered by a 12VDC 140 mA power adapter.
