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
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.
