What Is Massoth DiMAX?

DiMAX is Massoth’s modular digital system. The command station generates DCC driving and switching commands, supplies the track and connects Navigators, wireless receivers, feedback modules and other components through the Massoth bus. The technology is particularly suited to garden railways with long routes, several locomotives and high current consumption.

Depending on the power supply used, the DiMAX 1210Z provides up to 12 amps. The track voltage and maximum current level can be adjusted. This is important because a twin-motor locomotive with sound, lighting and a smoke generator requires considerably more energy than a small railcar. The maximum available output should therefore never be selected automatically.

Trains are operated using the DiMAX Navigator. The ergonomic handheld controller has a display, illuminated rotary knob, function buttons and emergency stop. It can be used through a bus cable or wirelessly with the appropriate radio equipment. This allows the operator to follow the train through the garden and remain close to the action during shunting.

The system follows the DCC principle and additionally supports typical functions of older LGB MTS systems. Some existing components can be integrated through suitable interfaces or bus converters. The specific device generation, firmware and bus protocol are decisive.

Massoth does not only manufacture command stations. Its range also includes feedback modules, switching decoders, turnout mechanisms, function modules, energy-storage units and workshop devices. A garden railway can therefore be expanded gradually from simple manual operation to a monitored multiple-train layout.

Your Recommendation

Prepare reliable outdoor operation

Plan Power, Wireless Coverage and Feedback in the Garden

Power Bus

Create Short Track-Feed Routes

A sufficiently heavy main cable and numerous track feeds reduce voltage drop along long garden railway routes.

Power Districts

Limit Faults to Individual Areas

On large layouts, the station, main line and storage area should have their own booster and short-circuit districts.

Wireless Coverage

Install the Receiver in a Raised Position

Walls, metal surfaces, terrain and vegetation affect the range. Test the position before completing the permanent installation.

Weather

Install Electronics in a Protected Location

The command station, power supply and open modules belong in dry, ventilated areas. Only components specifically designed for outdoor use should remain outside.

Feedback

Define Contact Positions Early

Detection points for shuttle routes, block operation and automatic turnout control should be planned during track construction.

Vehicles

Measure Current Consumption Individually

Multi-motor locomotives, sound, lighting and smoke generators determine the required total output more reliably than the number of trains.

Focused on large scales but technically flexible

Choose Massoth by Gauge

Gauges G and IIm

This is the principal application of the system. High current reserves, wireless operation, outdoor turnout mechanisms and robust vehicle modules are particularly suitable for LGB, PIKO and comparable garden railways.

Recommendation

DiMAX 1210Z, Navigator, wireless receiver and separate power districts.

Gauge 1 and Gauge 0

Large models benefit from the adjustable track voltage and high output. The decoder, power supply and maximum current level must suit the individual locomotive.

Recommendation

1210Z with an adapted voltage, heavy wiring and Powercaps.

H0, TT, N and Z

The command station can technically be operated at a reduced voltage. However, its minimum 4 A cut-off level is high for very small vehicles and requires particular protective measures.

Recommendation

Use only after careful current and safety planning.

From the power supply to the first wireless operation

Set Up Massoth DiMAX in Six Steps

Step 1

Determine the Power Requirement

Add the consumption of motors, sound, lighting, smoke generators and accessories.

Step 2

Select a Suitable Power Supply

The voltage and output must suit the command station and layout.

Step 3

Separate the Main and Programming Tracks

The two outputs must not be connected electrically.

Step 4

Connect the Navigator

Test wired operation and then register the wireless receiver and transmitter.

Step 5

Check Locomotives Individually

Check the address, speed steps, functions and current consumption.

Step 6

Add Modules Gradually

Test and document turnouts, feedback and automation individually.

Avoid faults and unsuitable purchases

Common Mistakes with Digital Garden Railways

Enabling Twelve Amps Without Checking

The highest level is only suitable for appropriately designed wiring and track sections.

Using Too Few Track Feeds

Long tracks and rail joiners can otherwise cause considerable voltage losses.

Hiding the Wireless Receiver Near the Ground

A clear, raised position improves the wireless connection in the garden.

Installing Unprotected Modules Outdoors

Electronics not specifically designed for outdoor use require a dry enclosure.

Connecting a Powercap Without Checking the Decoder

The connection, charging circuit and programming must suit the decoder.

Reusing Older MTS Devices Without Checking Them

Check the bus protocol, converter, firmware and available functions first.
