Operation overview
Digital Operation
The decoder FD-M is a multiple protocol decoder, that can operate with
and automatically recognises 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 Motorola format only in 14 speed levels.
Programming the decoder is done in DCC format by setting the
configuration variables and in Motorola format through the registers.
Analogue mode
The decoder can also be used in analogue model railway layouts. It can be
run with an A.C. speed control as well as with a D.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.
Switching the function outputs on or off is not possible in analogue
mode. They can be programmed so that they are either switched on or
off in analogue mode. The effects set for the outputs are active in
analogue mode as well.
Outputs to be switched with F0 are switched on or off in analogue
mode according to the direction of travel.
