10. OPERATING MODE 2
SYSTEM-AUTONOMOUS APPLICATIONS
In the operating mode 2 the command station is in charge of operations, similar in function to a com-
puter as in operating mode 3. “System-autonomous” (operating mode 2), in contrast to “module-
autonomous” (operating mode 1), can execute more difficult tasks that involve the cooperation of a
larger number of system components that, besides MX9 track section modules, may also include
MX8 accessory modules, accessory decoders and more.
The description of the ‘system-autonomous” applications should really be in the command station
and cab manuals but for “historical” reasons, though, we decided to place the “system-autonomous
block control” right here in this manual.
The configuration variables in the following table generally cover all system-autonomous applications
(operating mode 2), and there is no difference (at least no essential difference) to the CV’s used un-
der computer control (operating mode 3).

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
