RailCom® was developed by Lenz® Elektronik, Giessen, Germany,
and is a technology for transmitting information from the decoder
back to the command station. Until now DCC systems could only
transmit data from the command station to the decoder but could
never be sure if the decoder actually received the commands.
The locomotive can send the following information to the com-
mand station:
Locomotive address: The decoder transmits its address on request
by „Broadcast“. Detectors in a certain track sector can detect this
command. Thus, the command station can find out the location
of that particular locomotive.
CV information: The decoder can provide feedback about all CV
values to the command station per RailCom®. In future, a pro-
gramming track will not be necessary any more.
Meta data: The decoder can transmit status information such as
motor load, current draw of the motor, temperature etc. to the
command station.
In order for RailCom® to work all decoders and the command
station must be equipped accordingly. LokPilot decoders are
RailCom®-ready in terms of their hardware. However, it may be
necessary to carry out a firmware update in order to activate it.
Prior to use RailCom® must be unlocked by setting bit 3 in CV 29.
CV 28 offers further options. Ex works, RailCom® is active in ESU
LokPilot V4.0 decoders.
14. Special Functions
You may not yet be aware of some other highly specialised func-
tions offered by LokPilot decoders.
14.1. Directional Bit
The directional bit determines the driving behaviour when transit-
ing from an analogue into a digital sector (also refer to chapter
10.4.3.). If you want to set this directional bit, then bit 0 in CV
124 must be set.
14.2. Saving the status of functions
LokPilot decoders can store the current operational settings. Thus
the decoder continues running the locomotive as before after a
power interruption, if so desired.
The following data can be stored:
Status of functions:
Stores the information regarding which functions were switched
on or off and switches them accordingly once power is restored.
Current speed:
If it is stored then the locomotive will continue at this speed after
a power interruption disregarding what the command station may
transmit.
CV 122 is responsible for this. Storing of the status of functions is
turned on with bit 0, speed with bit 1.
