Digital Command
Control Mobile Decoder Part Numbers
Digitrax Decoders are numbered according to the
following scheme
Digitrax Decoder Part
Numbering System:
Current production Digitrax
decoders use the following numbering system:
The first character means that it is a digital decoder. This is
always a “D”.
The second character indicates the decoder’s physical size. This is based on the smallest
"scale" the decoder is designed to fit. This will be a Z, N, H, or G.
The third character is the current rating of the decoder. This
will be a 1, 2, 3, 4 or 5. We designate 1.25 & 1.5 amp decoders as 1s and
3.5 amp decoders as 3s for simplicity.
The fourth character indicates how many functions, including
directional lights, are available on the decoder.
The fifth character is a
Digitrax series designator. This
is a number from 0-9. Series 1 Digitrax decoders have standard or configurable
strobe function outputs. Series 2 decoders have FX function outputs, scaleable
speed stabilization and Transponding™. FX3 decoders have FX3
function outputs, torque compensation, SuperSonic™, scaleable speed
stabilization and Transponding™.
Additional letters may be
added to the decoder number to indicate which installation interface is used on
the decoder. If the decoder number ends after the series number, then it is a
wired decoder. The following table shows some of the interfaces currently
available on Digitrax decoders.

Installation interface designations are followed by a design number,
0-9, and sub-design letter, A-Z, when there is more than one
version of a particular
design.
