4. Operation overview

Possibilities of use
The carriage lighting WIB-31 to –33 can be used in digital layouts
driven in DCC or Motorola format as well as in analogue model railroad
layouts. For the power supply digital boosters or analogue a.c. or d.c.
transformers can be used.
Design of the PCB
The carriage lighting WIB-31 to –33 have inserted 8 LEDs. The colours
of lighting are:

WIB-31: yellow

WIB-32: bright white

WIB-33: or warm white
On the PCB (or after shortening the PCB, on the remaining section 1)
are apart from the LEDs:

RailCom compatible function decoder for DCC and Motorola format,

three switchable outputs for supplementary loads (e.g. back lighting,
additional lighting, electric couplings),

integrated smoothing capacitor as a flickering protection,

connecting points for two external bridging capacitors to supply the
LEDs and the function outputs of the decoder.

The length of the PCB as well as number and layout of the LEDs
correspond to the carriage lighting WIB-11 to -13 which are available as
well in the fluorescent colours yellow (WIB-11), bright white (WIB-12)
and warm white (WIB-13). Thus the (analogue) carriage lighting of the
10er-series is suitable especially for combining with the lighting of the
30s series in a block train.
Driving in digital Operation
There is a function decoder integrated on the PCB, that can operate
with and automatically recognises both DCC or Motorola formats.
The number of addresses is dependant on the format being used.

Motorola-Format: 255 addresses

DCC- Format: 127 Basis-addresses or 10.239 extended addresses.
In the DCC format the decoder can be driven in all speed levels (14, 28
or 128).
Programming the decoder is done in DCC format by setting the
configuration variables and in Motorola format through the registers.
Switching the functions in digital mode
The LEDs on the PCB, the three function outputs of the decoder and
further functions are switched via the function F0 to F15 in DCC format.
In Motorola format the function keys F0 to F4 are available. The
functions F5 to F9 can be switched via the function keys F1 to F4 and
