3.3 Connecting transformer, track and programming track
The 6-pins plug 1 is used to connect the transformer, the track and
the programming track.
1 Programming track
2 Programming track
3 Digital voltage to the track
4 Digital ground to the track
5 Ground 16 V AC from Transformer
6 16 V AC from Transformer
The transformer
In order to obtain a trouble free operation of the IB-COM use a
transformer of min. 52 VA output power. The maximum output AC
RMS voltage from the transformer should not exceed 18V.
The transformer must be connected to clamps 5 and 6 (brown and
yellow, respectively).
Ensure that the wires from the transformer have not been swapped
with those from the track, and that short-circuits did not occur
among the various wires of the connector. A short-circuit between
the transformer and the track could destroy the output stage of the
IB-COM.
The track
For 2-rails tracks, the track must be connected
to terminals 3 and 4 of 6-way plug.
For 3-rails tracks (Märklin) the track centre rail
is connected to terminal 3 (red Märklin cable)
and the track ground to terminal 4 (brown
Märklin cable) .
The programming track
The programming track is a special track for programming and
reading out the configuration variables of loco decoders.
Both rails of the track must be isolated from the normal track! With
Märklin tracks you isolate rails and centre rail.
During programming the isolation gaps must not be bridged (wagon
locomotive bogies).
The track is connected to terminals 1 (brown) and 2 (red) of the
screw terminal plug for socket 1.
