Explanation of important CV parameters
Current digital systems like the DiMAX System provide a comfortable way to program addresses. All
CVs including CV29 are calculated automatically and programmed at the same time. The original
address setting of the eMOTION XL Decoder is “3”. In case of a Decoder reset, the address will be
reset to this value.
Loco Address
•
Each locomotive running in a digital system needs a digital address.
•
The NMRA Standard provides two kinds of addresses:
Low (short) addresses (1…127) and high (long) addresses (128…10239)
An address must be stored in the Decoder to enable the Decoder to recognize the commands
that are meant for it.
•
The low address is stored in CV 1. The maximum value is “127”. In addition bit 5 in CV 2 must
be “off” (value 0)
•
The high address is divided into two values and is stored in CV17 and CV18.
In addition bit5 in CV29 must be set to “on” (value 1)
The long address must be calculated and stored into CV17 and CV18:
CV17 = address / 256 (store only the whole-numbered value)
CV18 = address – (CV17x256)
Motor Control
•
The direction of driving (including the direction related functions) can be defined by setting
CV29 bit0 accordingly.
•
Three settings of speed control are available:
•
14 speed steps (CV29 – bit1 = Off)
•
28 speed steps (CV29 – bit1 = On)
•
128 speed steps (is detected automatically) MTS I and II require a 14 speed step setting
34
