LD-G-43 tams elektronik
Info: Ground connections, voltage outputs, return conductor
At   the   locomotive   decoder   LD-G-43   some   connections   are   available   on   the   front   side
(according to the definition for the PluX interface) as well as additionally on the rear side: 
Colour of
wire
Front
side
Rear
side
Ground connection for reed contacts / hall sensors braun X5 GND
Minus pole (-) for backup capacitor or buffer circuit (UPS)
Power supply for Hall sensors blau X6, X9 RC / V+
Positive pole (+) for backup capacitor or buffer circuit (UPS)
Return conductor (RC) for all functions (+)
The relevant connections on the front and rear are each interconnected and can therefore be
assigned according to practical requirements. It is recommended to use the connections on
the   decoder   rear   for   the   connections   of   reed   contacts,   Hall   sensors,   backup   electrolytic
capacitors and/or a buffer circuit. 
3.6. Using decoders with interface connectors 
Many newer locomotives with DC motors already have an interface installed at the factory. By
using   a   decoder   with   a   suitable   interface   you   save   the   cutting   of   the   connections   and
soldering work on the locomotive. 
The locomotive decoder LD-G-43 is available with an 8-pole interface according to NEM 652 or
with a PluX22 interface according to NEM 658. The interface connects the decoder with the
motor, the rail pick-ups, the lighting and/or additional accessories. 
8-pole
Number of poles: 8
Morop standard: NEM 652
 Note: 
The 8-pole interface plug must be plugged onto the socket so
that the markings are on top of each other after installation. 
As this interface has no reverse polarity protection, it is possible
to   insert   the   plug   into   the   socket   rotated   by   180°.   During
commissioning,   the   decoder   will   then   usually   be   irreparably
damaged.
Tip: The  marking  is sometimes  difficult to  recognise  (or not
present).  It is  (or should  be)  on the side where the orange
connection cable (for motor connection 1) is located. 
PluX22
Number of poles: 22
Morop standard: NEM 658
RailCommunity standard: 
RCN-122
 Note: 
The   PluX22   interface   is   designed   to   be   protected   against
polarity reversal.
There is no hole in the loco-side socket at the position of the
decoder-side index pin (X11). 
With retrofitted sockets all 22 holes are usually open, the decoder
can then be plugged on rotated by 180°. During commissioning,
the decoder is then usually irreparably damaged.
