Key Features

  • High-Speed Communications
    The SEL-2894 has very low latency adding only 375 µs of through delay back-to-back. It works with EIA-232 signals from 300 bps to 19,200 bps.
  • Three LED Indicators
    TX and RX green LEDs show incoming and outgoing fiber-optic states. A standard yellow alarm LED indicates a transmission problem.
  • Selectable Time Reference
    A side-selector switch on the SEL-2894 configures the internal clock for either external or internal time reference.
  • Flexible Power Supply
    The converter connects directly to a standard 9-pin serial port and receives power directly on Pin 1 so no external power is required when used with SEL relays. The converter can also receive power from an external supply when connected to other devices.

 

Applications

  • Connect any EIA-232 device to an IEEE C37.94 fiber-optic network.
  • Apply the SEL-2894 to relays without an IEEE C37.94 interface to transmit digital communications (such as MIRRORED BITS®) through IEEE C37.94 multiplexers.
