Page 12 Track section module MX9
APPLICATION EXAMPLE –
Module-autonomous block control
In contrast to the previous examples, here the main sections of the MX9 are linked to each other.
The status of a signal influenced block (whether it is set to “stop” or “go”) depends on the occupancy
state of the following block.
The mode of action when trains are stopped inside a block is identical to the previous examples (in-
cluding when pusher trains are involved).
Automatic block control, which is the usual operating mode and is indicated by yellow keyboard
LED’s on the cab, can be overridden to issue a “Stop” (red LED) or “Go” (green LED) command to
any block by pressing the relevant key on the cab or by switches connected to the MX9 (with
MX9ASE boards plugged-in).
Block control can be laid out cyclically, that is the last block depends on the state of the first block
(see example below), but may also end in a manually controlled signal influenced block or in an entry
block to a staging yard.
Applicable CV settings for this example (Signal influenced block at main section 3 of the MX9):
CV # 21 = 40 (Stopping with L-H, because block 1 is longer in this example)
CV # 22 = 30 (Stopping with U-H, because the stop section here is shorter)
CV # 23 = 31 (The ones digit in the value “31” defines a cyclical dependency of block 1)
CV # 2, 3, 4 = .... optional: for limited speed when “green” and in opposite travel direction;
see “Initial speed limits” in the CV table above.
CV # 29, Bits 1.0 = 00 if “OCC. INDICATORS” socket is empty or used for occupancy detection
= 01 if socket is used for signals in opposite direction
= 11 if socket is used for external switch inputs (ASE plugged in)

The same example but with bidirectional block control using the same sections:
If block control for the track sections in this example should also be possible in the opposite direction,
then the CV’s need to be programmed for this mode.
CV # 21 = 143 (The ones digit in the value „143“defines a cyclical dependency of block 3)
CV # 22 = 130
CV # 23 = 130
CV ‚ 29, Bits 1, 0 = 01 as mentioned above, for signals in opposite direction

External switches or relays that
simultaneously actuate signals
and MX9 inputs. Actuation with
the cab is also possible instead.
Green
CV # 21 = 30 Station entry block with signal
CV # 22 = 51 (first track in staging yard, pin #1 for turnout actuation)
CV # 23 = 53 (second track in staging yard, pin #2 for turnout actuation)
CV # 24 = 54 (third track in staging yard, pin #3 for turnout actuation)
CV # 25 = 30 Block following the staging yard
CV # 3, # 4, # 5 = 23 (this as an additional definition to CV #21, #22 and #23, not as main defini-
tion as is normally the case):
That is, trains in direction A->B are to drive through with speed limit L (=2) if signal is
green but trains traveling from B->A are to drive without speed limit (=3).
Signals for A->B can be connected to socket SIGNALS (if MX9ALA are plugged in);
Switches for actuating a route can be connected to the socket SIGNALS if MX9ASE is installed; this
excludes signals from being plugged in at the same time.
The individual track sections can also be controlled by the cab; LED above key is yellow if in normal
mode (=automatic), switching LED to red or green overrides automation and forces the signal to its
corresponding state.
