§
After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created
by accident. This would cause faulty operation or, in the worst
case, damage. You can remove excess solder by putting a clean
soldering tip on the spot. The solder will become liquid again and
flow from the soldering spot to the soldering tip.

4. Operation overview

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 RailCom decoders to the digital
control unit or to special receivers (so-called detectors). To transfer the
RailCom messages special RailCom boosters supplying the so-called
RailCom cutout have to be used.
Mode of operation
The RailCom detector RCD-1 is connected to a seperated rail section
and receives the RailCom messages applicated to the respective rail
section. These are possibly:
§
Addresses of the vehicle decoders in the rail section. The decoder´s
address is sent permanently.
§
CV-values of the vehicle decoders in the rail section. The CV-values
are sent only after a read out command (i.e. sent by the control
unit).
The RCD-1 verifies the signals it receives and sends the "clean" signals
via a special databus to special accessory devices (i.e. RailCom display
devices, units passing on data to a PC or to the digital control unit.)
