4.1. Modes of operation

Digital operation
The function decoder FD-R Extended is a multiple protocol decoder,
that can operate with and automatically recognise both DCC or
Motorola formats.
The number of addresses is dependant on the format being used:

Motorola-Format: 255 addresses,

DCC-Format: 127 Basis-addresses or 10.239 extended addresses.
In the DCC format the decoder can be driven in all speed levels (14, 28
or 128). In the Motorola format the decoder can be driven in 14 or 27
speed levels. Driving all 27 speed levels can be done only with central
units which support this mode (e.g. MasterControl). With central units
which allow 14 speed levels only, it is only possible to select every
second speed level.
Programming the decoders is done:

in Motorola format by setting the registers,

in DCC format by setting the configuration variables (direct
programming, DCC conform) or by POM (programming on main = main
track programming). Note: The configuration variables reserved for the
SUSI interface ## 897 – 1024 cannot be programmed by POM.
Analogue mode
The decoder can also be used in analogue model railway layouts run
with a D.C. speed control, and with restrictions with an A.C. speed
control. When putting the vehicle on the rails the decoder recognizes
automatically if it is run in analogue or digital mode and sets the
corresponding operation mode. The automatic recognition of the
analogue mode can be switched off.
