1 Introduction
The locomotive decoder DH05A/B, DH10A/B and FH05A are compatible with the protocols of SelecTRIX
Standard SX1 / SX2 as well as with NMRA-DCC-Standard. They can be controlled by every central control
unit working with one of these data formats.
They can be used for normal direct current motors as well as for coreless motors.
The operation on alternating current supplied layouts with switching impulse is not allowed. The
impulse excitation will destroy the decoder.

6 Decoder-Installation
6.1 Preparation
Check if the locomotive is in perfect running order electrically and mechanically, prior to any mounting work.
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 a digital decoder. New
locomotives should be run in at least 30 minutes in each direction of travel.
Before you start, insulate the motor and all its terminals completely against track connections (chassis,
collector slipper, etc.).
Both motor connections must be disconnected from the ground!
Further on, all condensers have to be removed, particularly those associated with the connections of light
and motor.
Fix the decoder with a double sided adhesive tape.
6.2 Check after the insertion
The first test should be executed in the programming mode (e.g. by reading out the address). In case of an
incorrect feedback (confirmation signal) to the central unit ("error"), please check again the correct
assignment of the connections respectively if the motor is really disconnected from the chassis electrically.

8
6.3 Installation
There are three variants to connect the decoder:
1 In case your locomotive is equipped with an interface (NEM 651), you should take the decoder
DH05A/B-1, DH10A/B-1respectively FH05A-1. They have already the appropriate connections for this
plug. Shorten the ribbon cable up to approximately 5 mm and remove the rest of the insulation. The
decoder can be inserted into the interface without any problem now.
2 If the locomotive is not equipped with an interface jack, the decoder must be wired up individually. For
this purpose you should use decoder with flexible wires (DH05A/B-3, DH10A/B-3respectively
FH05A-3).
3 The decoder DH05A/B-0, DH10A/B-0respectively FH05A-0should be used by experienced model
railroaders only as the connection wires must be soldered directly onto the decoder.

9
Connect the decoder wires accordingly to the following diagram:
red wire with the right track wire (G1)
black wire with the left track wire (G2)
orange wire with the motor wire, which was connected to the right track (M1)
gray wire with the motor wire, which was connected to the left track (M2)
white wire with the front light (LV)
yellow wire with the rear light (LR)
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)

10
Function outputs:
The function outputs AUX1 and AUX2 are on the underside of the decoder and must be connected to
the consumers with individual wires (see Illustration, page 2).
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 adjustment options of the
respective operating system).

Reading out the extended characteristic values is executed by the entry of the character sequence
00–111
and a subsequently push on the programming key.
Writing of the extended characteristic values is executed by the entry of the character sequence
00=VAI
and a subsequently push on the programming key.
Notice:
Coreless motors should be operated with regulation variant 4 and pulse width 1. Damages due to
incorrect adjustments are excluded from the warranty.
Caution!
Reading out and entering extended characteristic values overwrites the default-values of the decoder.
In case you have varied the extended characteristic values, the default characteristic values of the
decoder must be entered anew.

14
7.3 Operation
Put the locomotive on the programming track and read out the programming parameters of the decoder.
The default value should be 01-542. Program the desired locomotive address and start running the
locomotive keeping the other parameter 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 of the programming track. Never put such a locomotive into
operation!
7.4 Explication of the signal-stopping section
One-part signal-stopping section:
In front of the signal one track section is controlled by a diode. The decoder must be programmed on
one-part stopping section (-). The locomotive will be braked to a halt.
Two-part signal-stopping section:
In front of the signal there are two track sections. The first one is controlled by a diode and the
locomotive will be braked down to internal speed step 3 in this section. The second one is without
supply and the locomotive will stop just in front of the signal. The decoder must be programmed on
two-part stopping section (=).

of your programming device.
Notice:
In case the speed steps programmed on the decoder differ from those of the control device,
malfunctions may occur. Please pay attention to the respective information concerning your digital
system.
