Assembly Instruction
Feedback Module
with integrated
8-fold track occupancy detector
for the s88-feedback bus
from the Digital-Professional-Series !
RM-GB-8-N-B
⇒ controls up to 8 different tracks
(current detection from 0,001[1mA] up to 3 ampere).
⇒ integrated voltage control
(avoiding "track free" feedback in case of power failures).
⇒ separated by opto isolation
(between track voltage and feedback bus).
⇒ s88 standard connections and s88N(5V)
(with 6-poles s88-pinbars and RJ-45 sockets].
⇒ suitable for following digital control systems:
Märklin CS1 and 2, CS3 (plus) over L88 with 5V, Twin-
Center, Intellibox, HSI-88(-USB), EasyControl, ECoS,
DiCoStation.
This product is not a toy! Not suitable for children under 14 years of age! The kit
contains small parts, which should be kept away from children under 3! Improper
use will imply danger of injuring due to sharp edges and tips! Please store this
instruction carefully.

Introduction:
You have purchased the 8-fold feedback module RM-GB-8-N
with integrated detection of track occupancy for your model
railway. The RM-GB-8-N is a high quality product that is supplied
within the assortment of Littfinski DatenTechnik (LDT).
We are wishing you having a good time using this product.
Feedback modules RM-GB-8-N of the
Series can be operated with your digital model railway without
any problems.
The RM-GB-8-N is suitable for all digital model railways with
s88 feedback bus.
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
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.
For the diodes please keep special attention to the correct
polarity (marked line for the cathode).
With reason to different makes of electrolytic capacitor you will
find different markings of the polarity. Some are marked with "+"
and some are marked with "-". Each capacitor has to be
assembled to the board that the marking on the capacitor is in
correspondence with the marking on the pc-board.
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. radiator) or work with an
electrostatic safety pad.
Before assembling the clamps please connect the 2-pole and the
3-pole clamps together to a block with 14 connections.
Please glue the below two label onto the RJ-45 sockets for the
identification of the output socket BU1 (wire directed to the
central unit) and BU2 (wire from the next feedback unit).
