6.1 Functions

Operation can be controlled either by conventional DC command stations or by digital central units supporting the
formats SelecTRIX 1 and 2, NMRA-standard (DCC) or MM1/MM2-standard.

Automatic switchover from conventional DC to digital operation.

In case of digital operation the last programmed system will be activated. Automatic switching into a certain
operating mode is not possible because of the multi protocol operation. For switching a parameter (e.g. the
locomotive address) is to be readout and must be written again in the required operating mode. Thus the switching
to the required track protocol is completed.

SelecTRIX 1 31 speed steps, 100 addresses

SelecTRIX 2 127 speed steps, 10.000 addresses, 16 additional functions

DCC Short addresses (1-127), long addresses (0001-9999), with 14, 28, 126 speed steps

127 internal speed steps

Block section operation by simple diodes in digital operation

Light- and function outputs are (partly) dimmable and can be activated analogously

Shuntig gear

Light- and track connections are electronical changeable

All function outputs are freely programmable

Thermal protection

Reset function for DCC and SX2

The decoder can be uptdated:
The update can be executed on the incorporated decoder when the locomotive is standing on track (no need to
open the engine, free SW download from the internet)

FH05B, FH18A and FH22A support braking system with asymmetric digital voltage (four diodes connected in
series and one antiparallel diode), slow approach (with appropriate brake modules) and the bidirectional
communication (locomotive address check-back signal in DCC-operation, RailCom®).
