Introduction:

You have purchased the 16-fold Feedback Module RM-88-N as

a kit for your model railway. The RM-88-N is a high quality

product that is supplied within the assortment of Littfinski

DatenTechnik (LDT).

The Feedback Module RM-88-N from the Digital-

Professional-Series can operate on your digital control without

any problems.

The RM-88-N is suitable for the application on any digital

control unit which supports the s88 feedback bus

We are wishing that you will have a good time for assembling

and using this product.

General:

Tools required for the assembly

Please assure that the following tools are available:

• a small side cutter

• a mini soldering iron with a small tip

• solder tin (if possible 0,5mm diameter)

Safety Instructions

• All electrical and electronic components included in this kit

shall be used on low voltage only by using a tested and

approved voltage transducer (transformer). All components

are sensitive to heat. During soldering the heat shall be

applied to the respective component for a very short period

only.

• The soldering iron develops up to 400°C. Please keep

continual attention to this tool. Keep sufficient distance to

combustible material. Use a heat resistant pad for this work.

• This kit consist of small parts, which can be possibly

swallowed from children. Children (especially under 3 years)

shall not participate on the assembly without supervision.

Set-Up:

For the board assembly please follow exact the sequence of

the below assembly list. Cross each line off as done after

completing the insertion and the soldering of the respective

part.

Please put the clamps together to a block with 17 connections

before assembling the clamps to the board.

Special attention is required for the tantalum capacitor. The

leg with the mark "+" has to be inserted to the respective

marked position on the pc-board.

Resistor-networks are marked on one end with a printed

circle or a square. Assemble this component that way that the

marking corresponds with the marking between the first and

second bore on the pc-board. The first bore has been

additionally marked with a "1".

Please attend to the flat side of the transistor.

Integrated circuits (IC`s) are either marked with a half round

notch on one end or a printed point for the correct mounting

position. Push the IC`s into the correct socket assuring that the

notch or the printed point is corresponding to the half-rounded

marking on the pc-board.

Please attend to the sensitivity of the ICs to electrostatic

discharge, which will cause immediate damage of the IC.

Before touching those components please discharge yourself

by contacting an earthed metal (e.g. earthed radiator) or work

with an electrostatic safety pad.

Please glue the two labels onto the RJ-45 sockets for

identification of the output socket BU1 (cable in direction to the

central unit) and BU2 (cable from next feedback unit).

Soldering instruction Provided you have no special experience in soldering electronic components please read first this soldering instruction before starting the job. Soldering has to be trained! 1. Never use additional fluxes for soldering electronic circuits which contain acids (e.g. zinc chloride or ammonium chloride). Those can destroy components and printed circuits when not washed off completely. 2. As soldering material only lead free soldering tin with a rosin core for fluxing should be used. 3.

Connection of contacts: 2. Two-conductor rail-system: 1. Three-conductor rail-system If you use reed contacts or other potential-free contacts for feedback signals on your layout you can install the wiring to the feedback module RM-88-N as shown at the below circuit. At the feedback module RM-88-N all contacts can be connected which are switching against ground (mostly digital wire “brown”).
