Introduction / Safety Information:
You have purchased the High Speed Interface HSI-88 for the s88
feedback bus. The HSI-88 is a high quality product, which is
supplied within the Digital-Professional-Series of Littfinski
DatenTechnik (LDT).
We wish you having a good time using this product.
•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
damages caused by improper use or installation.
The finished modules in a case come with 24 month warranty.
Connecting the Interface to your digital
control center and Personal Computer
(PC):
•Attention: Please switch off your model railway by
disconnecting the transformers from AC-current, and
switch off your PC before starting the installation of the
unit.
Voltage (14 to 18V AC from any model railroad transformer) will
be supplied via clamp KL1 to the interface HSI-88.
If you use the HSI-88 on a 3L system (Märklin tracks with center
conductor) you can use feedback modules which switch to
ground connection.
In this case please pay special attention to the correct
connection of the supply cables “brown” (system ground)
and “yellow”.
The input of clamp KL1 is marked accordingly.
If your model railway software supports the HSI-88 you need a
second free serial port on your PC. This port will be mostly
indicated as COM-Port.
Use the supplied computer cable to connect the Interface HSI-
88 via the free serial port with your PC.

At last connect the s88-feedback modules to the HSI-88 Interface
by using the three 6-pole pin plugs marked LEFT, MIDDLE and
RIGHT.
With the HSI-88 you can build up 3 feedback lines. This will give
the advantage of speeding up the reading of the feedback
modules by three times.
Another advantage is the simple arrangement and installation of
your feedback modules below your model railway track panel.
Start always with connecting the first line on the input marked
as LEFT of the HSI-88. If you want to build a second line connect
it to the input marked as MIDDLE. A third line must be connected
to the input marked as RIGHT accordingly.
Even if you use only some few feedback modules on your model
railway track it is recommended to distribute the feedback
modules to all three inputs (LEFT, MIDDLE, and RIGHT) of the
HSI-88 evenly.
As a result, the feedback-information will be much faster
detected by the HSI-88 and transferred to the PC.

The above example shows a possible distribution of feedback
modules to the three inputs.
The administration and addressing of the feedback modules will
be supported by your model railway software.
How to register additional feedback modules please consult the
manual of your model railway software.
Standard feedback modules of the s88 feedback system
usually include 16 inputs.
With the HSI-88 up to 31 of those feedback modules (62 of LDT
RM-GB-8-N track occupancy detection modules with 8 inputs)
can be controlled. Max. 31 modules can be connected on each
bus line. The summary of all three lines shall not extend a total
of 31 modules.
All s88-feedback bus compatible feedback modules can be
connected to the interface HSI-88.
Beside the LDT modules RM-88-N and RM-88-N-O for moment-
contacts and the RM-GB-8-N for track occupancy detection even
different types of feedback modules from different manufacturers
can be used.
Different brands and types can be connected to the feed back
lines even if they are mixed.
Further examples for using the HSI-88 and other LDT products
for performing feedback tasks with various kind of contacts can
be downloaded from our Internet Page (www.ldt-infocenter.com)
from the download section.
For the HSI-88-B kit a solid low-priced casing is available under
the part number LDT-01. Further details are available on our
Internet Page.
Communication with the PC:
After switching on the power supply a red LED at the HSI-88 will
indicate ready-to-operate.
The HSI-88 works event driven that means that each feedback
information will be transferred directly to the PC. This saves
considerable PC resources and shortens the reaction time as
the PC does not have to poll feedback information in cycles
(which means delays) but the HSI-88 itself will report each
change to the PC directly and without delay.
During interaction between PC and HSI-88 via the serial port
the red LED will be OFF. As the interaction will be very fast the
LED will show therefore a kind of flickering.
If you want to include the communication with the HSI-88 into
your own written model railway software you can download a
list of complete commands from our LDT-Internet Page
(www.ldt-infocenter.com).
Trouble shooting:
What to do if something is not working as described above?
If you have purchased the interface as a kit please check
carefully all parts and all soldered joints.
Here you will find some descriptions of failures and the causes
respectively how to solve the problem:
1. The rail way software does not recognize the HSI-88.
Feedback information will not be transferred from Interface to the
PC.
•Is the LED of the HSI-88 on after switching the unit on? If
not, check the power supply on clamp KL1.
•Is the LED flickering after starting the rail way software?
Background: after starting the software the PC tries to
contact the registered HSI-88 Interface and the LED should
flicker. Does the LED not flicker it is possible that the COM
port is defective.
Check this by changing the serial ports of the digital
control unit with the port of the Interface HSI-88.
2. After starting the rail way software the LED of the HSI-88
Interface flickers. Nevertheless there will be no connection.
Deactivate the FIFO-Buffer of the connection adjustment for the
COM interface where the HSI-88 is connected to the PC. With
respect to the PC operating system (Win2000, XP, Vista, Win7,
Win8 e.g.) via Working Place, System Control, System and
Device Manager or similar.
