HSI-88-USB – Manual

The numbering of the feedback modules: The standard feedback modules of the

s88-feedback systems consist of 16 inputs. The first 16-fold module at the Left

input will be always the first feedback module within the feedback system. The

further counting will continue via the terminal Middle until the end of the right line.

With the HSI-88-USB is it possible to control up to 31 16-fold-feedback modules (62

of the type RM-GB-8-N with 8 inputs). To each bus line can be a maximum of 31

modules connected. But in summary to all three lines cannot be more than 31 16-

fold respectively 62 8-fold modules connected.

It is possible to connect all s88-feedback bus compatible feedback modules to the

HSI-88-USB. Apart from the LDT-Modules RM-88-N and RM-88-N-Opto for the 3-

conductor rail-system and the RM-GB-8-N with integrated track occupancy report

for the 2-conductor rail-system is it as well possible to use feedback modules from

other manufacturers. Different brands and types can be mixed within the feedback

lines.

Various application- and wiring-samples are available on our Web Site at the

Internet within the section Sample Connections and Downloads.

The High Speed Interface HSI-88-USB works event controlled: one or several

changes of feedback inputs will be reported to the PC at once. This saves

considerable computing time and will be noticed within a reduced reaction time

because the PC has not to request at a cyclical mode (and therefore delayed) about

changes but receives those reports actual from the HSI-88-USB.

Functional control:

If the HSI-88-USB has been connected to the switched-on PC via the USB-interface

the red LED will lighten up. Whenever feedback changes will be transmitted to the

PC the green LED of the HSI-88-USB will flash up.

4. HSI-88-USB implementing into your model railway software:

If your model railway software supports the HSI-88-USB you have to select at your

model railway software your digital central unit as the first digital system for the

driving and switching.

For the feedback reports you have to select at your model railway software the

HSI-88-USB as the second digital system.

The detailed procedure should be explained within the manual of your model railway

software.
