Features of the HSI-88

  • Fast (9600Baud), galvanically isolated connection to the computer via the serial port (RS232). Is there no free serial port available on your model railroad computer please ask at your computer shop about an “USB to RS232” converter. With this cable you can use an USB port as an additional serial port.
  • The 3 feedback lines additionally enhance the reading of the s88-feedback bus by 3-times.
  • 3 feedback lines will give you the advantage of a simple arrangement of the feedback modules below your layout.
  • It is possible to monitor a total of 31*16 feedback contacts with one bus-line or divided onto the three bus-lines.
  • Besides all standard-feedback-modules such as s88 from Märklin or our RM-88-N / RM-DEC-88 you can naturally operate on the HSI-88 as well our feedback modules witch optocoupling RM-88-N-O / RM-DEC-88-Opto and our feedback modules with integrated track occupancy report RM-GB-8-N / RM-GB-8.

Correct connection of the s88-standard feedback cables of all three feedback lines to the High Speed Interface HSI-88: Right hand and at the middle an interference-free twisted s88-standard bus cable from our delivery program. Left hand a ribbon-cable from Märklin or other manufacturer.

With the adapter Adap-HSI-s88-N is it possible to connect s88-Feedback Modules such as RM-88-N, RM-88-N-O or RM-GB-8-N directly via the screened Patch-Kabel to the HSI-88 in accordance to s88-N. For this connection shall be the Adapter Adap-HSI-s88-N simply plugged onto the three 6-poles pinbar of the HSI-88.
