What Is Digitrax?

Digitrax is a modular control system for DCC model railways. A command station generates driving and switching commands, a booster supplies the track and throttles provide the operating controls. Feedback modules, turnout decoders, radio receivers, computer interfaces and power-management components can be added later.

The DCS52 Zephyr Express is intended for compact layouts. The desktop unit combines a command station, 3 A booster, throttle, programmer and USB interface. It manages up to 20 simultaneously active locomotive addresses and throttles and has two Jump Ports for additional analogue DC controllers.

Large layouts use the DCS210+ or DCS240+. The DCS240+ has a selectable 5/8 A booster, three LocoNet sockets, USB, a separate programming output and a considerably larger locomotive and throttle capacity. Trains are operated using wired or wireless throttles.

Digitrax transmits DCC through the track, so DCC decoders from many manufacturers can be used. This does not mean that throttles and layout modules are freely interchangeable. These components communicate through LocoNet and must be supported by the command station or adapter being used.

In Europe, the power supply, track voltage, mains plug and radio approval must also be considered. Special CE versions are available for duplex radio operation. American radio devices should not be used merely because their connectors fit mechanically.

The network behind Digitrax

LocoNet Connects Throttles, Boosters and Feedback

Operation

Connect Throttles at Several Locations

Connection panels are distributed around the layout. A throttle can be plugged in, unplugged and used again at another location.

Radio

Use Duplex Throttles Without a Cable

The DT602DE and UT6DE communicate bidirectionally through a suitable European radio transceiver.

Wi-Fi

Use a Smartphone as an Additional Throttle

The LNWI connects compatible apps to LocoNet. The user interface is provided by the relevant Android or Apple application.

Feedback

Report Occupied Sections to the Command Station and PC

The BXP88 and other detectors transmit track occupancy, transponding information and current states through the network.

Accessories

Control Turnouts and Routes Locally

Stationary decoders such as the DS74 are installed close to the mechanisms and reduce long cable runs to the control panel.

Computer

Connect JMRI and Other Programs

The DCS52, DCS240+ and PR4 provide USB connections for decoder programming, control panels and automation.

North American and open DCC solutions compared

Compare Digitrax, NCE, TCS, MRC and DCC-EX

System Entry Point System Bus Mobile Operation Particular Strength
Digitrax DCS52 Zephyr Express LocoNet Cable, duplex radio, infrared and LNWI Highly modular and expandable for many operators
NCE Power Cab Cab Bus Throttles and proprietary radio solutions Central operating logic directly in the throttle
TCS LT-50 or CS-105 LCC Wired and wireless throttles depending on equipment RailCom and a modern network architecture
MRC Prodigy Express 2 Prodigy Cab Bus Cable, radio or Wi-Fi module Clearly arranged throttle operation
DCC-EX EX-CommandStation Depends on the hardware and project USB, Wi-Fi, WebThrottle or apps Open software and extensive customisation
European Alternatives Intellibox, ECoS, Lenz, PIKO or ZIMO LocoNet, ECoSlink, XpressNet or manufacturer bus Wi-Fi, radio or cable Straightforward availability and European support
The decisive difference: DCC allows compatible locomotive decoders to operate with different command stations. System buses, throttles, radio receivers, feedback modules and boosters are not automatically compatible across manufacturers.

Your Recommendation

Combine cables, duplex radio and smartphones correctly

Operate Digitrax Wirelessly

Duplex Radio

DT602DE and UT6DE

The throttles transmit and receive data. Locomotives can be selected and operated without plugging in the throttle first.

Radio Base

UR93E for European Layouts

The CE transceiver connects to LocoNet and improves the range and multipath reception in large layout rooms.

Smartphone

LNWI with WiThrottle or Engine Driver

One LNWI supports up to four mobile devices simultaneously. Larger layouts can use several interfaces.

Wired Operation

UP7 and Connection Panels

Wired throttles require no radio network and are particularly suitable for fixed operating positions and reliable exhibition operation.

Infrared

Short Wireless Connections with Line of Sight

IR throttles require suitable receivers and a largely unobstructed line of sight. Duplex radio is generally more flexible.

Network Security

Protect Public Layouts

At exhibitions, the Wi-Fi access, device names and permitted apps should be defined clearly before operation begins.

DCC is gauge-independent, but the power supply is not

Digitrax for Z, N, TT, H0, 0, 1 and G

Gauges Z, N and TT

With its moderate output, the DCS52 is primarily intended for N and H0. Gauge Z requires a lower track voltage or a suitable voltage-reduction device.

Suitable System Concept

DCS52 or a European DCC command station with adjustable voltage.

H0, H0e and H0m

Digitrax provides its widest range of options for these gauges. The Zephyr Express is sufficient for many home layouts, while the DCS240+, feedback and wireless throttles enable extensive multi-operator operation.

Suitable System Concept

DCS52, DCS240+, LocoNet throttles and BXP88.

Gauges 0, 1 and G

Large motors, sound, smoke and lighting require greater current reserves. Systems rated at 8 A require heavy wiring, short-circuit protection and separate power districts.

Suitable System Concept

DCS240+ or a powerful European large-scale command station.

Define the interfaces and expansion path before purchasing

Plan a DCC System in Six Steps

Step 1

Record the Locomotive Decoders

Check whether every vehicle supports DCC and which functions are required.

Step 2

Measure the Current Requirement

Do not estimate motors, sound, lighting and accessories solely by the number of vehicles.

Step 3

Choose the Operating Concept

Combine a desktop unit, wired throttles, radio and smartphones deliberately.

Step 4

Select the System Bus

LocoNet, XpressNet, LCC or the manufacturer bus determines future expansion options.

Step 5

Plan the Feedback Sections

Define the isolation points before ballasting and completing the permanent track construction.

Step 6

Check the European Version

Consider the power supply, radio approval, warranty and repair arrangements.

Avoid common misunderstandings

Common Mistakes with Digitrax and Third-Party Systems

Confusing DCC with Complete Compatibility

Locomotive decoders are more interchangeable than throttles, radio devices and system modules.

Using US Radio Devices in Europe

Choose the specified CE versions for the European market.

Planning a DCS240+ Without a Throttle

The command station requires a suitable LocoNet throttle or another operating solution.

Treating Booster Output as a Permanent Requirement

Separate power districts and protective circuits are safer than one large district.

Treating the LNWI as a Complete Router

The range and number of devices must suit the layout room and operating concept.

Ignoring Import and Service Arrangements

The power supply, spare parts, returns and firmware maintenance are part of the purchasing decision.

Is the DCS52 suitable for beginners?

Yes. It combines a command station, throttle, booster and USB in one device. LocoNet allows the layout to be expanded later.

Does the DCS240+ require a separate throttle?

Yes. The DCS240+ does not have an integrated throttle. A LocoNet throttle, app or computer-based operating solution is required.

Can I control Digitrax using a smartphone?

The LNWI connects compatible mobile devices and apps to LocoNet. Up to four devices can be used simultaneously with each interface.

Which radio version is suitable for Germany?

The DT602DE, UT6DE and UR93E CE versions are intended for Europe. The version approved for the relevant region is decisive.

Can a Digitrax throttle be used with an Intellibox?

Some LocoNet throttles can generally work together. The specific range of functions depends on the command station, throttle generation and supported LocoNet commands.

Can Digitrax be connected to an ESU ECoS?

The ESU L.Net Converter integrates supported LocoNet throttles and modules. Not every specialist function is necessarily transferred.

What is the difference between Digitrax and NCE?

Digitrax places a strong emphasis on a widely distributed LocoNet. NCE concentrates many operating functions in the throttle and uses its own Cab Bus.

Who is DCC-EX suitable for?

DCC-EX suits users who want open software, flexible hardware and individually configurable computer or Wi-Fi control.

What does Digitrax Transponding mean?

Equipped vehicles transmit an identifier. Suitable detectors can therefore recognise not only occupancy but also particular vehicles.
