Misc Details


The simplex IR receiver can handle infrared wireless communications. Unlike the duplex UR92, you must plug in the throttle to the LocoNet to perform some operations, such as selecting a loco to control.

This panel can receive infrared commands from nearly all Digitrax throttles.

  • Plug 'N Play with any LocoNet system
  • Simplex radio throttle must plug in to select, dispatch, or program locomotives
  • Simplex radio operates in the 900Mhz band
  • Supports approximately 10 radio throttles
  • Supports both Simplex Radio and infrared operation at the same time
  • Most layouts need only one UR91
  • One RJ12 6 pin Throttle jacks in the front of the panel for hooking up throttles and other LocoNet devices that do not use RailSync
  • Two RJ12 6 pin LocoNet jacks in the back of the panel for hooking up LocoNet devices that use RailSync
  • Indicator LED that shows the power state of a local track section
  • Includes PS14 power supply
