Example:
Assuming you would like to activate the SwitchPilot’s „zoom“
function on outputs 1 and 3, the value of CV 34 needs to be set
5 ( 1 + 0 + 4 + 0 = 5 ).
7.2. Programming with DCC systems
SwitchPilot decoders understand all programming methods of the
NMRA, so in addition to the programming track modes (Direct
Mode, Register Mode, Page Mode) also the main track program-
ming „POM“ (programming on the main).
With POM you can comfortably program your decoder without
having take your locomotive off the track. For this the central unit
must contact the decoder with its specific address, for example:
„Decoder 10, write value 1 into CV 3“. The decoder address must
be known. The reading of CV values is not possible in this case.
It is possible to read out CVs on the main track with RailCom®.
More information can be found in chapter 11.
CV values can be read and set on the programming track – a suita-
ble DCC system provided. Furthermore you can program decoders
on the programming track without knowing the decoder address
since the central unit uses commands like „Write value 1 to CV3!“
Each decoder that receives this command will also execute it.
ESU counts the bits from 0 to 7 as specified in the DCC norm
while some manufacturers (e.g. Lenz) count the bits from 1 to 8.
Please keep this in mind when programming our decoders with
such systems.
7.2.1. Programming on the programming track
For programming specific parameters of the decoder outputs the
SwitchPilot has to be programed on the programming track. This
is most practical prior to installation on the layout.
7.2.1.2. Connecting to the programming track
For programming please connect the SwitchPilot as shown in fi-
gure 11 to your digital system. In this instance the power must be
supplied from the command station.
The SwitchPilot “understands” all relevant DCC programming
modes. It is best to program it in DCC Direct Mode.
In order to be able to read out any data you must connect a load
to output 1 Out A that draws more than 60 mA, for instance a
light bulb or a 180 Ohm / 1 Watt resistor.

The reading of CVs should function with all DCC conformal cen-
tral units and was tested with ESU ECoS, Bachmann® Dynamis
ProBox®, Uhlenbrock® Intellibox® and Lenz® Digital Plus V3®.
Unfortunately,
Digitrax® units do not supply enough current on the program-
ming output, ZIMO® units sometimes report an over current.
Therefore, use the main track programming 7.2.2.
