Introduction / Safety Information:
You have purchased the model railroad data switch DSW-88
as a kit or as a finished module. The DSW-88 is a high quality
product, which is supplied within the Digital-Professional-
Series of Littfinski DatenTechnik (LDT) and can be connected
to your digital system via the s88-feedback bus without any
problems.
We are wishing you having a good time using this product.
The finished module and the finished module in a case comes
with a 2 years limited warranty.
•Please read the following instructions carefully. Warranty will
expire due to damages caused by disregarding the operating
instructions. LDT will also be not liable for any consequential
damages caused by improper use or installation.
General description:
The s88-feedback bus is normally built up as a continuous line
with all feedback modules behind each other.
This feature has its disadvantages on some model railway
layouts. If the digital central control unit is positioned at the
center of a model railway track the feedback line can only be
directed to the right or left hand side and has then to be re-
directed from the left or right end via the layout middle into the
opposite layout part.
The data switch DSW-88 gives you the opportunity to ramify
the s88 feedback bus at any position on the track.
Connecting the DSW-88 to the
digital model railway:
•Attention: Before starting the installation switch-off the
drive voltage by pushing the stop button or disconnect
the main supply from all transformers.

Connect the 6-poles plug to the Interface, Memory, Intellibox,
TWIN-CENTER or to the existing s88 feedback modules. The
connection cable has to show into the bottom of the data
switch. If you connect the data switch to an output of the High-
Speed Interface HSI-88 the cable shall show in a direction
away from the HSI-88.
The plugs of following feedback modules shall be plugged
onto the left or right 6-poles pin plug bar so that the cable will
point away from the data switch. Next to one end of the pin bars
you find a white mark. If you use LDT feedback modules with
interference-protected twisted connection cable the white
marking has to correspond with the white wire of the cable.
If you use feedback modules with a ribbon-cable the plug has to
be inserted that way that the cable will point away from the data
switch.

The first sample connection solves the above mentioned
problems of a digital control unit placed at the middle of a
layout.
In this example the data switch is connected directly to the
Intellibox to built two feedback lines.
The left line goes to the left layout side and consist of one
Märklin s88 feedback module and one s88 compatible RM-
DEC-88 from LDT. At the right line there are two LDT feedback
modules with integrated occupancy detector (RM-GB-8)
connected.
Next to the left connection pin bar is a rotary code switch
located. With a small screwdriver the number of feedback
modules connected to the left line must be set. At the above
sample there are 2 modules connected to the left line and the
code switch has to be set to 2. After the digital central unit has
red-out the feedback information the data switch DSW-88 will
know that after the read-out of the second feedback module it
has to switch-over to the right line.
The rotary code switch allows up to 15 modules for the left
line. Numbers from 1 to 9 are shown on the switch followed by
letters A to F. The letter A means number 10 and F number 15.
The exact allocation is printed on the board next to the switch.
The digital control unit or the PC software will assign an
individual address to each of the feedback modules with 16
inputs beginning from the central unit.
The module with the number 1 is always connected directly to
the digital control unit or the Interface, followed by module 2, 3
and so on.
In case you use our feedback modules with integrated
occupancy function RM-GB-8with 8 inputs two feedback
modules will be detected as one module with 16 inputs with one
address by your digital control unit or Interface/PC software.

Example 1 shows the module numbering in detail.
The numbering of the modules will be done behind the data
switch from left to right. The Märklin module s88 on the left line
has been assigned as module number 1, followed by the RM-
DEC-88 as number 2. The two RM-GB-8modules connected to
the right line will both have the module number 3 in this system,
as both together have 16 Inputs.
The second sample connection shows a feedback system with
7 feedback modules. The data switch DSW-88 is used behind
the second module to split the s88-feedback bus.
The left line connected to the DSW-88 has the assigned
modules number 3 and 4 and on the right line modules number
5 , 6 and 7 are connected. As there are 2 modules connected to
the left line the rotary code switch has been set to 2.
Further sample connections can be found on our internet site
(www.ldt-infocenter.com) in the area "Downloads". Please load
the file “DSW88_INFO_engl” onto your PC.
