Assembly Instruction
16-fold Feedback Module
for the s88-Feedback bus
from the Digital-Professional-Series!
RM-88-N-O-B
As Märklin s88 with 16 opto-coupling inputs.
Suitable for digital control devices and interfaces
with s88-feedback bus:
⇒ with 16 opto-coupling input connections
(for potential separation and high interference protection e.g.
for contact tracks [one isolated rail], switch tracks reed-
contacts or turnout feedback report).
⇒ for s88-standard connections and s88-N
(with 6-poles s88-pinbars and RJ-45 sockets).
⇒ suitable for the digital control:
Märklin-Digital~/=, Central Station 1 and 2, Intellibox, TWIN-
CENTER, 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 or injuring due to sharp edges and tips! Please store this
instruction carefully.

Introduction:
You have purchased the 16-fold Feedback Module RM-88-N-O
as a kit for your model railway. The RM-88-N-O is a high quality
product that is supplied within the assortment of Littfinski
DatenTechnik (LDT).
The Feedback Module
Professional-Series can operate on your digital control without
any problems.
The RM-88-N-O 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).
