 Swapping connections: in case of an incorrect wiring of the motor (M1 and 

M2 outputs swapped), lighting (LV and LR outputs swapped) and track (G1 and 
G2 swapped), there is no need to unsolder the cables, as the assignment of 
mentioned outputs can be interchanged electronically by adjusting decoder 
settings. Please see CV51 in “Programming” chapter of this User’s Manual for 
more information.

9.

 Check after installation: after finishing soldering work and connecting all 

cables, check all connections and soldering joints thoroughly once again. All 
consumers - motor, lights etc. should be reliably isolated from any of the track 
connections.

ZMO5A-1:

 it is recommended to additionally secure the digital decoder with a 

piece of shrinking tube that comes in the package. Use heat gun heated up to 
150 °C for this.

10.

 Test operation: put the locomotive on the programming track and read out 

the locomotive address. Program the desired locomotive address and start 
running  the  locomotive.  After  the  first  check  you  can  modify  the  driving 
parameters according to your requirements.

In case your command station or programming device returns an error during 
reading  out  the  locomotive  address,  please  check  again  the  wiring  of  the 
locomotive. Pay attention to the electrical separation of the motor and lights 
from the tracks. 

Never put such a locomotive into operation!

Programming

This digital decoder is based on Doehler & Haass® proprietary hardware and 
software technology. All functions and features of ZM05A digital decoder are 
equal  to  those  of  Doehler  &  Haass®  DH05C  multiprotocol  digital  decoder 
(except ZCLK/AUX5 and ZDAT/AUX6 outputs presented only in DH05C).

Here  is  listed  a  short  set  of  the  most  important  settings  of  ZM05A  digital 
decoder  in  DCC  mode.  Full  list  of  decoder  settings,  as  well  as  detailed 
information  about  all  available  features  and  programming  in  other  modes 
(MM, SelecTRIX 1 and 2) can be found on Doehler & Haass® official website:
