Limitations Of The Pd Series Compared To Our Dh Decoder Series - D&H FH16A Manual

Fahrzeug-/Funktionsdecoder Locomotive/Vehicle function decoder
The update (free software download from the internet) is possible in the installed state of the decoder on the track (no
need to open the engin) and is done either via the FCC digital centre or the programmer. If no corresponding hardware is
available, the company Doehler & Haass will provide a programmer on loan on request.
Decoders support braking with asymmetric digital voltage (four diodes connected in series and one antiparallel diode), slow
approach (with appropriate brake modules) and the bidirectional communication (locomotive address check back signal in
DCC operation, RailCom ).

5.1.1 Limitations of the PD series compared to our DH decoder series

The PD05A nano locomotive decoder is an especially small vehicle decoder for SX1, SX2 and DCC operation.
• No support for MM and DC-analog operation modes
• No support of SX1 programming (but SX1 operation is possible through SX2 parameter programming)
• No SUSI interface and no function outputs
• No extended function assignments (i.e.: no conditions, no initial mapping etc.)
• No automatic coupling process
• No brake ramp
