Introduction The locomotive decoders DH05C, DH10C, DH12A, DH14B, DH16A, DH18A, DH21A, DH22A and PD05A, and also the locomotive function decoders FH05B, FH18A and FH22A are compatible with the protocols of SelecTRIX standard SX1 and SX2, as well as with NMRA-DCC- and MM1/MM2-standard. They can be operated by every central unit supporting one of these system formats.

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 (PD05A: no MM and DC-analog, PD12A: only DCC) Automatic switch over from conventional DC to digital operation ...
Installation of the decoder Before installation check if the locomotive is in perfect electrical and mechanical condition. Defects and dirt must be eliminated first. Pay attention to the instructions of the locomotive producer. Only locomotives running smoothly in analogue mode should be equipped with digital decoder. New locomotives should be run in at least 30 minutes in each driving direction.
In case your locomotive is equipped with an interface according to NEM 651, you should take the decoder DH05C-1, DH10C-1 or PD05A-1. They have already the appropriate connections for this plug. Short the ribbon cable up to 5 mm and remove the rest of insulation. The decoder can be inserted into the interface without any problem now.

(DH05C-3, DH10C-3, DH16A-3, DH21A-3, PD05A-3, PD12A-3). 10 The decoders DH05C-0, DH10C-0, DH16A-0, DH21A-0, PD05A-0 and PD12A-0 should be used by experienced model railroaders only, as the connection wires must be soldered directly onto the decoder.
Function outputs: The function outputs AUX1, AUX2 (amplified, only if available) and AUX3, AUX4 (unamplified, only if available) are possibly on the underside of the decoder and must be connected to the consumer with individual wires or – if unamplified – via appropriate amplifiers. Notice: In case of an incorrect wiring of motor, lighting and track, there is no need to solder off the wires as the assignment can be interchanged electronically by programming (see setting options of the respective system...

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.
FH05B, FH18A and FH22A correspond functionally completely with the decoders described in point 5. Only features in direct connection with the engine control are missing. This fact is marked in the setting options of the corresponding system format. See: - Point 7.2 - Point 8.2: CV09, CV49, CV50, CV51/Bit 0, CV56 –...
Page 23
There are following variants for the connection of the locomotive function decoder FH18A: In case your locomotive is equipped with an interface according to NEM 651, you need for FH18A the connecting adapter N18-K-1. It has already the appropriate connections for this plug. Short the ribbon cable up to approxi- mately 5 mm and remove the rest of the insulation.

Fuction outputs: The unamplified function outputs AUX3 and AUX4 are at the underside of the decoder FH05B. They must be connected with the consumers via separate wires and via appropriate amplifiers. Notice: In case of an incorrect wiring of the light or track wire, there is no need to solder off the wires, as the assignement can be interchanged electronically by programming (see setting options of the respective system format: CV51 or.

Advice for decoder DH05C, DH10C, DH14B, DH18A, DH21A and FH18A: For SX1-programming a connected SUSI-sound module must be removed. It is sufficient to interrupt the supply voltage (red wire) during the time of SX1-programming.
Operation Put the locomotive on the programming track and readout the programming parameters of the decoder. The default falue should be 01-532. Program the desired locomotive address and start running the locomotive with those parameter values. After the first check you can vary the parameters of the engine freels to your requirements. In case your programming device indicates "Error", please check again the correct wiring of the locomotive and pay attention to the wiring instructions for connecting the programming track.

Operation Put the locomotive on the programming track and readout the locomotive address (CV01). The default value should be 3. Program the desired locomotive address and start runnig the locomotive keeping these setting values. After the first check you can vary the parameters of the engine freely according to your requirements. In case your programming device indicates "Error", please check again the correct wiring of the locomotive and pay attention to the wiring instructions for connecting the programming track.
Programming with Märklin-central unit 6020/6021 'Short' programming allows entering figures between 0 and 79, i.e. in short mode just setup parameters with val- ues from < 80 can be changed, if the desired value should also be < 80. 'Long' programming allows entering figures between 0 and 255 einzugeben, i.e. in long mode all setup parame- ters with values from 0 to 255 can be changed.
Page 46
Short mode After changing in programming mode the decoder is in short mode. The engine lighting falshes slowly and periodically. Enter now the number of the CV you want to change, e.g. 01 (double-digit). Activate the reversion of the driving direction for confirmation. Lighting is now flashing shortly two times. ...
Page 47
Activate the reversion of the driving direction for confirmation. Then the locomotive is flashing again. You may now enter further CVs in long mode which you want to change. The long mode can be left by switching the track voltage off and on again or by STOP. SUSI-mode You gain the SUSI-mode by writing value 09 in CV09 in short mode.

Please make sure that the function output you have chosen for connecting the electric coupling has a sufficiently high capacity! We recommend the connections AUX3 and AUX4 of our decoders, which are designed for currents up to 1 A. Hint: Use the coupling functions of our decoders (Timer for switching-off AUX*) to make sure that the function output will be switched off in any case according to a maximum activation time specified by you.
Supplement 5 Automatic coupling procedure ("Coupling waltz") Principle function If a locomotive with attached wagon train has been driven into the station in forward driving and now the wagon train should be uncoupled, the locomotive must approach the wagon train backwards to relieve the coupling. Then the cou- pling must be activated by relaxed towing hook.
Page 65
Using the coupling function of our decoder it must be ensured that the function output will be switched off in any case according to a maximum activation time specified by you. Otherwise the destruction of the electric coupling is possible. The time, while coupling is activated, is defined by the switching-off function: CV117 Timer for switching-off AUX1 CV118 Timer for switching-off AUX2...

Operating the couplings with 2 function keys Should the couplings be connected for example to AUX3 (in front) and AUX4 (at the rear), times are to be entered at AUX3 and AUX4. The mapping of the function keys (which function key should control which coupling), is set by the normale function mapping (see next page).
