Voltage Buffer; Analog Operation; Notes For Operation With Dcc; Long Address - LGB mSD3 Información Complementaria

These instructions give additional information about
the 27-pin decoders with up to 32 functions. However,
the foundation or starting point is always the operating
instructions included with the decoder / locomotive.
The information before you is not for inexperienced
users. We generally recommend that you document
all changes to the decoder settings for possible
troubleshooting.

Voltage Buffer

The decoder has a buffer that allows you to negotiate
areas of track without voltage. However, this also
applies to track in front of signals or the stop button on
the controller. With mfx or DCC, you have the option of
doing extensive settings to this buffer.

Analog Operation

Locomotives equipped with this decoder basically
can be operated with analog. Analog track voltage is
recognized automatically.
You can also turn on functions for analog operation.
The appropriate CVs can be found in the table on P.14.

Notes for Operation with DCC

The CVs from CV 257 to CV 512 occupied in several
instances. The appropriate selection must be set in
CVs 31 and 32 in order to access these CVs (reading
or writing).

Decoder info

Long Address

This decoder can be controlled in DCC by means of a
short (CV 1, address 1 – 127) or a long address (CV 17 &
CV 18, address 1 – 10239). Both addresses are basical-
ly always occupied. CV 29, Bit 5 is used to determine
which of the two addresses is currently valid.
The settings for the long address are calculated as
follows:
X = Address / 256 (only the whole number part)
CV 17 = X + 192
CV 18 = Address – (X x 256)
Example:
Address 1324
X = 5 (1324 / 256 = 5,17)
CV 17 = 197 (5 + 192 = 197)
CV 18 = 44 (5 * 256 = 1280; 1324 - 1280 = 44)
CV31=16 CV32=0
CV31=17 CV32=0
CV31=17 CV32=1
CV31=17 CV32=2
CV31=18 CV32=0
CV31=18 CV32=1
CV31=255 CV32=255

Multiple Unit Address

If the locomotive is to be used as part of a multiple unit
lashup, a multiple unit address can be entered (CV 19)
that can be used to address all of the powered units in
the multiple unit lashup. The normal addresses (short
and long) are not effective as soon as a multiple unit
address > 0 is entered.
Since a locomotive that is part of a multiple unit lashup
can no longer be addressed separately, individual
functions can be turned on for the multiple unit lashup
too.
The appropriate CVs can be found in the table on P.14.

Speed Levels

This decoder can be operated with 14 or 28/128 speed
levels (CV 29, Bit 2). Make sure that the setting on
the decoder is compatible with the settings on your
controller.
Operating Modes / Configuration of the
Outputs
The decoder's switching functions can be configured.
Things such as lights can be dimmed or other opera-
ting modes can be set.
Appropriate CVs can be found in the table on P.14.
Settings can be found in the table „Operating Modes"
on P.13.

Function Mapping

It is possible to assign functions controlled from the
decoder to function buttons as desired (mapping).
This can be programmed in mfx with the Central
Station (60213/14/15/16/26) or in DCC by means of the
appropriate CVs.
If function mapping is done in DCC, it will also be
effective with mfx and vice versa.
It is basically possible to assign several functions to
one button and one function to several buttons.
Several functions can be controlled by means of SUSI
depending on the layout of the decoder.
Miscellaneous
Function mapping is very extensive and complex. Each
individual mapping is done by means of three settings.
The following is defined when doing this:
- Which function is being activated (Sound, AUX, ...)
- How is the function being activated (activator)
- Possible stipulations for this function
After this information has been set, it is stored jointly in
a „line". Up to 80 lines (0 – 79) can be stored. All stored
lines are taken in by the decoder.
