11. OPERATING MODE 3
MX9 under COMPUTER control
In operating mode 3, all MX9 functions are controlled by the computer (usually with STP software) –
this is also the original application for which the MX9 was developed. It doesn’t matter to the MX9 it-
self whether it is operated in mode 2 (see above) or 3, in both cases control is taken over by a proc-
essor in the form of a command station or a computer.
The configuration variables are therefore identical to the ones in the previous chapter and the same
CV table is printed below, although that could change through software extensions in the future.
References and tips to MX9 track section arrangements for computer controlled layouts are given af-
ter the CV table!

The address that is used to access the module with
the cab or computer (STP…).
Externally (i.e. at the cab), the address is displayed
as 900 ... 963, internally as a CV however, it is
stored as 0 ... 63.
CV # 1 = 0: causes a HARD RESET - all CV’s are
reset to the default values including the
address, which is set to 900.
Normal reprogramming of the address to 900 DOES
NOT cause a hard reset. It’ll only change CV #1 to
0; all other CV’s remain untouched.

In the default mode, all track sections remain un-
powered at first (state “A”), after the system is pow-
ered up and are set to “H” (stop) shortly thereafter.
They remain in this mode until the first command is
received from the command station or computer.
In place of this initial state (“H” as default after start-
up), each main section can be set to a different
speed limit:
= 0: see text above, „H“ (= Halt/Stop) after start-up
= 1: „U“ (= Ultra low speed)
= 2: „L“ (= Low speed)
= 3: „F“ (= Free, unlimited speed)
= 5, 6, 7: Intermediate steps „1/6“, „3/6“, „5/6“
= 100: Limits called by switch inputs: H - L - U - F
= 101: Sequence A - H – L - F
= 102: Sequence A - H - U - F

are affecting the operation of the MX9, can be com-

A value of “0” defines

or
operating mode 3
for the respective main section
Connecting track sections to the MX9 is the same regardless of the operating mode chosen. Only
one rail, the one connected to output “P” of the command station, needs to be divided into sections.
The other is connected as one continuous rail to the output marked “Schiene N” at the back side of
the MX1. Each double socket belongs to one main section which provides terminals for two sub sec-
tions.
ATTENTION: The system depends heav-
ily on a good ground circuit. A poor wiring
job or not enough feeder wires con-
nected to the “N” rail may cause different
kind of problems such as the unex-
plained dropping of train numbers, a
stopped train creeping out of a stop sec-
tion, etc!
A MAIN SECTION is made up of two
side by side sub sections, which share
the signal controlled speed influence (i.e.
identical speed limits, identical function
control and identical position codes on
