The DS74 can only drive one Tortoise or similar turnout motor per output.


The DS64 Accessory Decoder allows you to install and operate your turnouts directly through any DCC system that has turnout control. The DS64 can operate various turnout motors - solenoid turnout machines to slow motion motors. A summary of the features:

  • Operates four turnouts.
    DS64 mounted under layout, driving 8 slow motion machines
    • Slow motion machines. Can drive up to 2 per output
    • Solenoid (snap) machines
  • Switch inputs for turnout control
  • LocoNet Control
  • Integral capacitor discharge.
  • Operates from track power or a separate power supply.[1]
  • Buffered switch inputs.


Although this may be Digitrax's lowest cost accessory decoder, it still packs a punch for those needing turnout control for slow motion machines. Summary of features:

  • Control 4 slow motion turnout machines from your DCC throttle.
  • Quick set up for sequential addresses (like the DS54)
  • Independent address set up also available (you can choose any stationary address for each turnout machine)


Decoder for single Kato Unitrack turnouts. Recommended for HO scale.

SE8C Signal Decoder

The SE8C can drive as many as 32 signal heads with many popular LED signal types.

It can also be used to control up to 8 slow motion turnout machines as either turnout control or control for semaphore type signals.

Power Management


PM4 PCB. Four relays, one per channel. Card edge connector behind relays connects the PCB via an edge connector (not shown)

Power manager, 4 outputs, each output can function as an auto reverse module or circuit breaker (not both). It can be supplied by multiple boosters, or only one. Various parameters can be altered, including trip current for the circuit breaker.

This unit requires some patience soldering all the wires to the edge connector. Amendment: HO Scale rail joiners can be soldered to the wires making up the harness. The rail joiners may then be slipped onto the solder tails of the card edge connector and soldered in place. Slipping heat shrink tubing over the joint will protect it from accidental shorts and cross-connections.

Mounting the unit requires #5 or smaller screws, or the edge connector can be mounted and the card inserted. Amendment: If the card edge connector is cross-drilled at the mounting flanges and attached to the face of a board or panel, the screw should pass through a 3/16" spacer sandwiched between the screw mount end of the PM4 and the mounting surface. This should be used to keep the board level in the connector and not strain the contacts unevenly.

Auto Reversers

Digtrax offers the AR1 for auto reversing in reverse loops.

The Digitrax BXPA1 is a LocoNet Auto reverser with added features for Detection, Transcending, and Power Management.

Utility Panels

Digitrax makes a number of utility panels, which are used to connect throttles to the throttle bus, in this case, Digitrax's LocoNet.

Utility Panel Notes

Also see Digitrax Wireless Notes

The Utility Panels provide power to the throttles plugged into them when connected via LocoNet. For more reliable operation, the use of an external DC Power Supply is recommended. There is a jack for power.

Track Status LEDs: Two screw terminals are provided on the rear, which may be connected to the power bus. This is optional and not required for normal operation.

  • When track power is on, the LED will be lit.
  • When Zero Stretching is in use, the colour of the LED will change according to the direction of the locomotive.
    • To check, select Loco 00, set throttle to "99", and toggle the direction. The colour indicated will change.

There are five RJ jacks.

  • Two on the front for throttles
  • Two on the rear for Loconet
  • One on the side for Loconet
    • This jack lacks Rail Sync. It is used to connect one accessory to your LocoNet

LNRP/LNRP Xtra LocoNet Repeater Module

The LNRP LocoNet Repeater Module isolates and protects large LocoNet configurations. It permits greater expansion of the LocoNet bus system. The LNRP allows "protected" sections of LocoNet to continue operating when a fault occurs, automatically reconnects to the faulty section when the fault is cleared.

This UP has been replaced by the LNRPXTRA LocoNet Repeater Module

Main article: LNRP

UP5 LocoNet Universal Interconnect Panel

The basic Utility Panel, which allows you to connect two tethered throttles, and includes additional LocoNet connections. There are connections to allow the track power to be indicated on the panel front. An LED on the front panel can be used to indicate local track power conditions.

The rear has two connections for LocoNet, and a third connection on the side. The side connection lacks RailSync, but can be used for a throttle or another Loconet device that does not need Rail Sync. It cannot be used for connections to more than one device.

The front connections are intended for use with a throttle. The front jacks use a diode OR'ed connection to the Rail Sync lines to provide power to the throttle. Using other devices (loads) as well as cable arrangements can cause issues with downstream devices connected via the front panel.

Devices such as boosters, the LNRP, accessory decoders and occupancy detectors require both Rail Sync and LocoNet connections for proper operation. They should be connected to the rear jacks only.

UP6Z LocoNet Universal Panel and 3 Amp Z Scale Voltage Reducer

This device has 6 LocoNet jacks, and reduces the track voltage by 4 or 6 volts for Z scale DCC operation. It does not look like the other utility panels.

UR90 IR Receiver Unit

Similar to the UP5, except it has an Infrared (IR) eye to detect IR signals from IR capable throttles. Can handle up to 10 throttles. For stable IR operation, several are usually needed, as the throttles work best in line-of-sight mode with the panels. (They work much the same as the IR remotes for a television.)

UP1, UP2 and UP3

These Universal Panels have been discontinued.

Networking and Computer Software

LocoNet WiFi Interface

Main article: LNWI

LNWI or LocoNet Wifi Interface is a device that allows you to connect WiFi devices to LocoNet.

This device was announced in August 2017.

UR92 DigiGroup Setup Utility

Software provided by Digitrax to enable advanced users to configure their duplex system. Requires an IBM PC compatible computer.

If the software detects a UR92 on LocoNet you can read the current Duplex Group Name, RF Duplex Channel and the Password.

Edit any of these settings and upload these values to any UR92 connected to LocoNet. The start channel scan allows a quick scan of the available channels to see how much signal (and possibly interference) may be present at your location. The graphics show the peak signal and average detected during scanning. Useful in helping setup the layout for optimum Duplex performance.

JMRI now includes a utility called the Duplex Network ConfigurationTool. This tool will do the same things as the DigiGroup Setup utility.
