The LoDi-KSM

Why do you need a reversing loop module on a model railway system? 

In principle, reversing loop modules are only required for the 2-wire system. 

The reverse loop module switches a reverse loop automatically.

A reversing loop occurs, as you can see in the picture, when the power supply is crossed when the train drives backwards or turns in a circular section when it enters the track again.

Here you can now see that the red line crosses the stream over the blue line.

This is then called a loop.

In order to avoid a short circuit here, you need a  special switch or relay that reverses the polarity of the supply voltage of the track in the reverse loop.

The properties of the LoDi-KSM(-P)

• Reversing loop module (KSM) for your digital model railway and track sizes from Z to G.
• The reverse loop module is independent of the track format.
• Our KSM is undetectable by feedback, which means your feedback will not show "Occupied" just because the reverse loop module is connected to it.
• Only the locomotive triggers an occupancy message as usual. 
• The KSM is fully RailCom-capable. The RailCom data channels 1 and 2 of the locomotive are themselves
  sent back via the KSM section.
• It can be switched between automatic and manual mode, for this you must have a normal switch output on your decoder or LoDi operator.
• Our modules support the LoDi-KSM(-P).
• LoDi operator 16-SD-FL
• But it can also be controlled with any other switching decoder. 

1. The LoDi-KSM(-P) and its connections

2. Overview of connection details

Here you can see the connection variant on a LoDi booster.

All common digital command stations and boosters from any manufacturer can be connected to the LoDi-KSM(-P). The module works completely independently.

This connection example uses the LoDi-KSM(-P) via an occupancy detector.

This is required if you want to report back your reverse loops or report them occupied.

Occupancy detection modules from any manufacturer can be connected to the LoDi-KSM(-P). 

3. Connection to LoDi operator or points decoder

The LoDi-KSM(-P) modules from 6/2021 have a 3-way dip switch. Here the LED can be switched on and off via Dip 1. Dip 2 and 3 behave as described above.
