RailCom:

Thanks to RailCom, which is a solution by Lenz, our tools can not only receive data from
the DCC signal but can also send feedback to the command center. To make this happen,
you need to select a booster that can handle the "cutout". For example: Lenz LZV100, ESU
ECOS or Roco Z21. Cutout is the short moment after every DCC package, when there is no
voltage in the track and when both rail lines are short cut. The decoder sends data in this
moment which is received by the detector. Data are divided into two channels. The first
channel contains the actual address of the decoder (short, long, consist), which is sent in
every cutout after each DCC data package. The second channel contains the POM pro-
gramming answers, speed, petrol level (coal, water, gasoline, etc.) or error information.
The answer can leave only after having received the DCC data package to the own ad-
dress. DigiSound-4.x is currently sending the address, speed, flag bits and POM data. Rail-
Com can be enabled by bit3 of CV29. Bit0 of CV28 enables channel 1 and bit 1 enables
channel 2.
