1 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. The locomotive decoder PD12A supports only DCC and DC-analog. All
decoders can be used for normal direct current motors as well for coreless motors.
The operation on alternating current supplied layouts with switching impulse is not allowed!
The switching impulse destroys the decoder!
Exception: DH21A and DH22A
2 Safety instructions
This product is not suitable for children under 14 years. It might be swallowed by children under 3 years!
An improper use involves a risk of injury due to sharp edges and points.
3 Warranty
The functioning of every decoder is fully tested before delivery. Should nevertheless a failure occur, please contact the
dealer where you purchased the decoder or directly the producer (Doehler & Haass enterprises). The warranty period
is two years from the data of purchase.
4 Support and help
In case you have any problems or questions please contact us by email: [e-mail]
Usually you will get an answer within a few days.

Notice:
PD12A is a locomotive decoder for DCC- operation only (and DC-analog).
There are following limitations compared to our DH-decoder series:
No support of operating mode SX1, SX2 and MM
No SUSI-interface and no unamplified function outputs
No low frequency motor control
(16 kHz or 32 kHz can be chosen)
No extended function mapping
(i.e.: no conditions, no initial mapping etc)
No automatic coupling process
(Timer for switching- off AUX1 and AUX2 are however available)

13
5.1 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 (PD05A: no MM and DC-analog,
PD12A: only DCC)
Automatic switch over 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. 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
State of art load regulation, in this way an especially smooth control mode
Different control variants for an optimal adaption to the motor
127 internal speed steps
Adjustable motor frequency (low frequency, 16 kHz, 32 kHz) (PD05A and PD12A: only 16 kHz, 32 kHz)
Block section operation by simple diodes in digital operation
Light- and function outputs are (partly) dimmable and can be activated analogously
Shunting gear
Motor-, light- and track connections electronically changeable
All function outputs are freely programmable
Thermal protection
Reset function for DCC and SX2
The decoder can be updated:
Updating 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)
Decoders support braking 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®).

14
5.2 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.
Before starting installation, insulate the motor and all its terminals completely against track connections
(sliders, chassis etc.).
Both motor connections must be disconnected from the ground!
Further on all capacitors have to be removed, particularly those associated with the connections of light and motor.
Fix the decoder with a double sided adhesive tape.

15
5.3 Connection of the decoder
There are following variants to connect the decoder:
1 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.
2 In case your locomotive is equipped with an interface according to NEM 652, you should take the decoder
DH16A-2, DH21A-2 or PD12A-2. They have already the appropriate connections for this plug with an
8-pin plug. The decoder can be inserted into the interface without any problem now.
3 In case your locomotive is equipped with a 12-pin interface (PluX12), you should take the decoder DH12A or
PD12A-4. They have already the appropriate connections for this plug. The decoder can be inserted into the inter-
face without any problem now.
4 In case your locomotive is equipped with a 14-pin interface (mTc14), you should take the decoder DH14B. It has
already the appropriate connection for this plug. The decoder can be inserted into the interface without any
problem now.
5 In case your locomotive is equipped with a 16-pin interface (PluX16), you should take the decoder DH16A-4. It has
already the appropriate connection for this plug. The decoder can be inserted into the interface without any
problem now.
6 In case your locomotive is equipped with an 18 interface (Next18), you should take the decoder DH18A. It has
already the appropriate connection for this plug. The decoder can be inserted into the interface without any
problem now.
7 In case your locomotive is equipped with a 21-pin interface, you should take the decoder DH21A-4. It has already
the appropriate connection for this plug. The decoder can be inserted into the interface without any problem now.
8 In case your locomotive is equipped with a 22-pin interface (PluX22), you should take the decoder DH22A-4. It has
already the appropriate connection for this plug. The decoder can be inserted into the interface without any
problem now.

16
9 In case your locomotive is not equipped with an interface jack, the decoders must be wired individually. For this
purpose you should use the decoders with flexible wires (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-0should be used by experienced
model railroaders only, as the connection wires must be soldered directly onto the decoder.
For above variant 9 connect the decoder wires according to the following diagram (see also the chart on the following
page):
red wire with the right track wire
black wire with the left track wire
orange wire with the motor wire, which was connected to the right track wire
gray wire with the motor wire, which was connected to the left track wire
white wire with the front light in driving direction
yellow wire with the rear light in driving direction
green wire function output AUX1 (only DH16A-2/3 and DH21A-2/3)
violet wire function output AUX2 (only DH16A-3and DH21A-3)
blue wire common return, can carry up to 30 volts (+VS) (only DH16A-2/3 und DH21A-2/3)
In addition for SUSI-interface (only if available):
red wire SUSI-supply voltage (ZVS)
blue wire SUSI-clock (ZCLK)
gray wire SUSI-data (ZDAT)
black wire SUSI-ground (GND)

17
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
format: CV51 or par031, par032, par033).
5.4 Check after installation
The first test should be made in programming mode (e.g. by reading out the address). If there is not correct check-
back signal to the central unit ("Error"), check again the mapping of the connection or the electrical separation of the
motor from the chassis.
