Rautenhaus Digital Driver



Plained above, a loco is halted, if the positive part of the digital power runs from the right rail through the decoder to the left rail but the negative part is blocked by the brake diode. If the posi-tive part of the digital power runs from the left rail, as seen in the direction of travel, via the decoder to the right rail, the loco.

digital command control

In 1980, a small German electronics engineering company, Döhler & Haass, developed a digital command control system for model railways and offered it to the many German and Austrian model railway manufacturers to include it in their range. Only Trix was interested, but it took another 3 years before Selectrix became available to the public. Selectrix was introduced at the 1982 Nuremberg Toy Fair, where a prototype was shown. Right from the start there were decoders available that were small enough to build into N-scale locomotives, including very small 4-wheeled engines. The first Selectrix equipment looked a bit different from the units offered nowadays, but all components are compatible. This brings me to the big advantage of Selectrix: ALL available components are compatible and work with each other, regardless of manufacturer. There are a few limitations, mainly in the range of available decoder addresses. Adresses from 1 to 99 work on all Selectrix systems.

Selectrix took a great leap forward with the introduction of the second series of components in 1992. New, even smaller, decoders became available and the control devices were upgraded. The new system offered a cheap starter kit which can control only 9 locos, but with addition of a second controller, the whole adress range becomes available. A new feature is that Selectrix can run NMRA DCC decoder fitted locos, although the NMRA mode is limited to even short adress numbers and offers only 14 speed steps.

At the moment most new developments in Selectrix come from other manufacturers like Rautenhaus and Müt (Digirail). Both offer command stations, loco and accessory decoders, handheld and desktop controllers and miscellenous hardware.

Selectrix features

Selectrix has 112 adresses available, these must be divided between locomotives, accessory decoders and feedback decoders, it is recommended to use loco decoders adresses in the 1-99 range. Do not use adress '0'. With a 'translator' module you can add a second databus for adding extra accessory and feedback decoders. All loco decoders have 31 speed steps, back EMF feedback speed control to ensure smooth running, directional lighting and one momentary extra function ('horn'). One accessory decoder can drive 8 turnouts or signals, or 16 momentary outputs (for uncouplers). A feedback decoder can sense 16 block sections. Selectrix has a unique method of transferring data, with two databuses, one for data and a second bus to feed boosters. Both buses use 5 wire cables, fitted with 5-pole DIN plugs. The land-based devices ( boosters, accessory decoders, feedback modules) have matching sockets. The cables can be purchased or when yo have a little soldering experience you can make them yourselves. The buses can be split, ringed etc. in any configuration and the maximum cable length is well over 50 metres per bus.

Recent developments

A trend seems to develop that Trix will be leaving the Selectrix system and therefore other manufacturers will fill in the gap left by Trix. At the moment most new products are introduced by Müt and Rautenhaus. At the Nürnberg 2005 Toy Fair, Trix has introduced the Trix Systems range, starting with the 'Mobile Control' unit, a handheld unit that plugs into a trackside booster unit. The Trix Systems range will support both DCC and Selectrix standards. Special 'Connect' adapter boxes will be introduced to connect your Trix Systems main unit to an existing Selectrix and/or DCC equipped layout. From now on Selectrix is gradually phased out by Trix and new Selectrix developments are most likely to expect from smaller manufacturers like Rautenhaus and Müt.

Trix Systems

Trix Systems is the name for the new Digital Command Controls system by Trix. The design of the equipment is the same as their 'Märklin Systems' counterparts, only the knobs are green instead of red. The system design is different as are the command protocols supported. The image below shows how a full system could be built up, also showing the 'Connect' options.


As you can see, the 'Central Stations' unit could be connected to both a DCC system (manufacturer unknown) and a Selectrix systems. All Triz Systems equipment supports both DCC (NMRA) and Selectrix protocols, so old Selectrix-decoder equipped locos ran run without limitations. More details are to follow when more information is available.

Manufacturers who offer Selectrix compatible components:

Trix, now owned by Märklin showed a prototype in 1982, products became available from about 1985 onwards. At the moment the future of Trix Selectrix products range is unclear, the NMRA DCC based 'Trix Systems' range will take over gradually. German language.
