7.1.1.2. Bits and Bytes

Most CVs contain numerical values: CV 8 for example contains
the manufacturer's identification. This one can range from 1 to
255. Other CVs can be understood as a collection point of diffe-
rent switches which together control different functions (most
often turning on or off). Good examples are CVs 28 and 29: The
intended value for this CV needs to be calculated. This value
depends on the desired parameter. Take a look at the table in
Chapter 17 and its description for CV34: First decide which option
needs to be turned on or off. In the value column are two numbers
for each option. If the option is turned off the value is set 0,
otherwise a number between 1 and 8. Add those two numerical
values for this specific option and you will get the value which
needs to be written into the CV.
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
programming „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
suitable 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
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 main track

The SwitchPilot can remain installed on your layout during the
programming. In order for the main track programming to work
your digital system must also understand „Programming on the
Main: (POM) for solenoid devices. In addition you must know
the decoder address of your SwitchPilot decoder.
Please make sure to carefully read Chapter 8 so you understand
the difference between turnout number and decoder address.
Thanks to the built-in RailCom® technology, ECoS owners with
firmware 1.1.0 or later can program the SwitchPilot while it is
installed on the layout. More can be find in chapter 11.

7.2.2. 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.
