7. The Feedback Monitor
If model railway layouts are to be controlled automatically (e.g. by
IB-Switches or computer control), then the control system needs
status signals, which communicate which track section is occupied
by a train. Only then can turnouts or signals be suitably switched
and affect trains.
Feedback modules monitor the track sections and convey the state
"a train is here" or "no train is here" to the central processing unit.
This train feedback is passed on via the LocoNet, either to the IB-
Switch 65400 to trigger train controlled switching sequences or via
the interface to a computer program, which can coordinate its
control problems accordingly.
Altogether a total of 2048 inputs is possible.
7.1 LocoNet Feedback
The valid address range for LocoNet Feedback modules is 1-2048,
i.e. a max. of 256 Feedback modules for 2-rail (63 340) with 8 inputs
each, or 128 Feedback modules for 3-rail (63 350) with 16 inputs
each, can be connected with the Intellibox. The modules can be
connected either to the LocoNet B or LocoNet T socket of the
Intellibox.
7.2 Selecting Monitor mode
The monitor mode can be selected by multiple operation of the
[mode] key or the [mode] key immediately followed by [2]. The
centre part of the display will change accordingly.
7.3 The Display
In the monitor mode the middle part of the display shows 16 blocks
each indicating a feedback input. After switching the Intellibox on,
this is always the first block with addresses 1-16.
The hollow blocks mean a vacant message, the closed an occupied
message.
7.4 Key Assignment
In the monitor mode each key in the middle key
group on the Intellibox is assigned to a feedback
input. If one of these 16 keys is pressed, the
state of the relevant input of the attached
feedback module, with ‘0’ for vacant or ‘1’ for
occupied, is indicated in the display.
