Product Features

  • Activity/Status LED (Orange)
  • Auto-Reset Hardware Watchdog Circuit
  • Addressable (1-7) TYPE 5 Databus ID

Since the ELK-M1XSLU is functionally a serial expander (RS485 to RS232), it shares the same Type 5 databus ID as standard M1XSP serial expanders. A maximum of seven Type 5 serial expanders may be connected to an M1; the M1XSLU is counted as one of these seven.

The ELK-M1XSLU should be mounted as close as possible to the RadioRA2 Main Repeater. An 18" 9-pin flat ribbon serial interconnect cable is provided.
