Introduction / Safety Information:

You have purchased the feedback module RM-88-N-O for your

digital model railway.

The RM-88-N-O is a high quality product, which is

supplied within the Digital-Professional-Series of Littfinski

DatenTechnik (LDT).

We are wishing you having a good time using this product.

The finished modules come with 24 month warranty.

• Please read the following instructions carefully. Warranty will

expire due to damages caused by disregarding the operating

instructions. LDT will also not be liable for any consequential

damage caused by improper use or installation.

• Attention: Please switch-off your digital control unit and

unplug all transformers from AC-current before starting

any installation.

General functions:

The feedback module RM-88-N-O contains 16 inputs and is

compatible to the Märklin feedback module s88. The module

contains additionally opto-coupling inputs and is therefore

extremely interference protected. This makes it as well possible

to connect without problems potential bounded contacts,

such as two-rails-two conductor model railway systems.

Connecting the RM-88-N-O to command

stations or interfaces:

Reports of up to 31 feedback modules RM-88-N-O can be

evaluated by a Märklin INTERFACE, Central Station 1 and 2,

Intellibox, TWIN-CENTER, EasyControl, ECoS, HSI-88-

(USB) and DiCoStation.

On each Märklin Memory can be up to 3 feedback modules

RM-88-N-O connected.

All feedback modules will receive the operating current from

the s88-feedback bus. This will apply for s88-standard

feedback module and for the feedback module RM-88-N-O.

If you want to extend your layout with RM-88-N-O feedback

module you can combine those with our feedback module

RM-DEC-88(-Opto), RM-88-N, RM-GB-8(-N) respectively with

s88 feedback module of other manufacturers.

The addresses of the feedback module are related to the

sequence of the connection to the command station

respectively to the interface. The feedback module, which is

directly connected to the central unit, will receive always the

address 1. Further details can be found within the operation

instruction of your command station respectively your

interface.

The feedback module RM-88-N-O contain two 6-poles

pin-bars for the s88-standard connection and as well two

RJ-45 sockets for a bus connection according to

s88-N

. At the

RM-88-N-O are pin-bars and sockets marked with OUT and

IN.

Out indicates the connection in direction to the command

station or interface. IN indicates the connection to the next

following feedback module within the s88-bus line.

Command stations and interfaces are always equipped with

an s88-input for an s88-standard connection.

For the s88-standard connection is an interference

protected twisted s88-bus cable with original s88-bus plugs

available.

The plugs of the s88-bus cable are correct attached onto the

6-poles pin-bar of the RM-88-N-O if the white single wire

corresponds with the white marking on the pc-board next to

the pin-bar.

The direction of the cable has to be directly away from the

feedback module. Additionally attend to the position of the

plugs on the 6-poles pin-bars. No offset will be acceptable.

For the

s88-N

s88-bus connection we offer a screened blue

patch-cable with RJ-45 plugs.

Attention: Command stations with PC-network connection

(e.g. Central Station 1 and 2 and ECoS) contain as well a

RJ-45 socket. It is not acceptable to connect the RM-88-N-O

to the RJ-45 network sockets.

Connection of contacts:

1. Three-conductor rail-system

Switch rails, contact rails and reed-contacts can be

connected to the input clamps 1 to 16 of the feedback module

RM-88-N-O as shown below.
