14. MX9 modifications for MX9ASE applica-
tions
Also see chapter 4 if the MX9 was not delivered with this modification;
ATTENTION:
the MX9 module must be modified before MX9ASE plug-in boards can be installed and switches used as input
signals. MX9ALA boards on the other hand can be installed at any time
This modification is performed by ZIMO on request (additional internal conductors from the processor to the plug-in
sockets, which are not present on the printed circuit board), even after the modules have been delivered.
Remove the acryl cover and bottom plate. The modification requires the connection of the following
points with thin wires (also see photo below):
- from IC 74HC138 (the one on the left), Pin 10 – to the first and third 20-pin connector, pin 9 on both
(counted from the front, connector side)
- from IC 74HC138 (also the one on the left), Pin 11 – to the second and fourth 20-pin connector,
also to pin 9 on each (counted from the front, connector side)
The two pictures show one way to make these connections. Two unused holes (they were originally
planned for something else), shown in the left picture, are used to bring the wires from one side of
the board to the other. The wires could also be brought to the other side by wrapping them over the
outside edge of the board if preferred.

15. Glossary
CAN bus:
Is an international standard for the secure data transfer between electronic modules and control
units. It is used in the automotive industry, among others. ZIMO is using this protocol via the cables
(CAN bus cable) connecting the command station with the cabs, accessory modules, track section
modules, turn table modules, computer and more.
The CAN bus cable is also known as the cab cable.

Signal controlled speed influence (aka: „location dependent control“, „HLU“ - method):
For prototypical train operation more is needed than just the ability of controlling more than one lo-
comotive per track as is the case with DCC. Secure train operation, as in centralized traffic control is
also part of it and involves signals, block control, route control etc.
The conventional method of cutting power to stop trains in front of a red signal is not a satisfactory
one using DCC. For one, all functions become inaccessible (lights, smoke etc.) and the prototypical
slow stopping and acceleration of trains is not possible.
ZIMO made it possible by integrating a special process of a signal dependent train control in the af-
fected components (especially loco decoders) of the DCC system. Additional control information is
sent to the track section that is supposed to stop a train automatically. When a train enters this stop
section (H section), it will come to a prototypical stop, that is with the lights and all other auxiliary
equipment still operating,

Turnout ladder:
Under turnout ladder we mean a number of turnouts and their positions. Which turnouts that become
part of such a ladder and what position each has to be in, needs to be defined first and can later be
called up on demand.
Note: In literature of other model railroad manufacturers, turnout ladders are often referred to as
routes. ZIMO uses the term route for higher levels of operation that combines turnout ladders and
track section control for automation and collision avoidance (which is most often not available with
other systems and therefore requires no distinction either).
Route:
A route as used here is an extended turnout ladder. It is a combination of turnouts and their intended
positions, track sections (connected to track section modules MX9) and may also include push but-
tons panels.
Line, Block, unidirectional, bidirectional:
The term Line is used for a length of track, usually connecting two stations, consisting of a series of
blocks. A block is a series of at least two track sections of which the last is usually a stop section.
Unidentified lines do not have an address assigned by which they could be activated. They are al-
ways active as long as they exist, that is, are not overwritten by a new definition process. They are
especially simple to define and use but are limited in their application compared to identified lines,
which are defined as part of a turnout ladder.
Unidirectional or bidirectional means that a track may be used in one direction only or both. Routes
and lines are by definition unidirectional. The actual track, on the other hand, can be bidirectional.
Each direction is then defined as a separate route or line.
