of 16 V or two goldcaps with a minimal voltage sustaining capability of
5,5 V.
In order to supply the three function outputs of the decoder you can
connect a second additional external bridging capacitor. It is not
possible to use goldcaps here, as the minimal voltage sustaining
capability is 25 V or 35 V (when connecting the PCB to analogue a.c.
voltage).
Feedback with RailCom
RailCom is a log for bi-directional communication in digital model
railway layouts controlled in DCC-format. It allows e.g. the feedback of
the address and the CV values from the decoder to the digital control
unit or to special receivers (so-called detectors). The decoders must be
designed to send the RailCom messages.
When so programmed, the integrated function decoder sends
(continuously) the (basic, extended or consist) address to the detectors
(so-called RailCom broadcast datagramm) and transfer a CV message
after a DCC CV read-out command.
Sending RailCom messages is only possible in layouts with a DCC signal
on the rails. That is the reason why it is not possible to use the
RailCom-function in a pure Motorola environment, but only when at
least one other locomotive or function decoder on the layout is
controlled in DCC format.
