UP5 Universal Panel

The UP5 replaced the UP3 in 2006.

A maximum of 10 panels can be powered from a PS14 power supply. Additional panels may not work correctly without the addition of another power supply.

Additional throttle connections to your LocoNet system.

UP5 Simplifies hook-up, maintenance & troubleshooting of LocoNet, add a few to make traditional tethered walk-around operation a snap.

The UP5 consists of a small PCB with 5 LocoNet jacks, a faceplate and an LED for track status. The LocoNet jack on the right is used for throttles only or other devices which can function with a LocoNet T connection.

The other RJ12 jacks are two LocoNet T for use with throttles on the front, the rear pair are LocoNet B used to daisy chain the device to other LocoNet devices such as additional utility and radio panels.

Two screws on the rear of the unit allow connection of a track feeder, which supplies the "Track Status" annunciator on the front.

A power supply jack on the left side for an optional external power supply. External power is advised to avoid loading the LocoNet with multiple panels.

UP5 PCB. The connections on the right with the LED between them are the front LocoNet T jacks.

Supplied with Digitrax Starter Sets


  • Plug 'N Play Installation
  • Gives your layout a professionally finished look.
  • Two RJ12 6 pin LocoNet jacks in the back of the panel for hooking up LocoNet devices that use RailSync.
  • Two RJ12 6 pin Throttle jacks in the front of the panel for hooking up throttles and other LocoNet devices that do not require RailSync.
  • One additional RJ12 6 pin Throttle jack on the side of the panel for hooking up LocoNet devices that do not require RailSync.
  • Indicator LED that shows the power state of a local track section.
  • 2mm power jack that allows you to make the UP5 a battery saver terminal for your throttles by connecting a PS14 DC power supply.
  • Two #6-32 right angle screw terminals for local track bus connections for power and diagnostics.


As the image to the left shows, there are five RJ jacks on the PCB. The two on the left side are LocoNet B, which pass through the RailSync signals to devices further down the chain. The jack at the top is a LocoNet T connection, as are the two on the right. The front panel will be fixed to the right side, the LED can be used to indicate track power is on. This is done by connecting feeders to the screws at the left side.

The bottom edge shows the barrel connector for an external power supply, which is recommended to avoid loading the RailSync lines.

  • If LocoNet crashes when connecting a throttle, one of the steering diodes which provides power (taken from the RailSync lines) to the throttle has failed.
