HSI-88

High Speed Interface for the s88-feedbackbus!

The HSI-88 is an INTERFACE between the s88-feedbackbus and the RS 232 - serial port of a Personal Computer.

 The interface includes three s88 bus-plugs. This offers the advantage of a much faster s88 bus handling and the possibility to build up three bus-lines at the system!

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 . For this connection shall be the Adapter Adap-HSI-s88-N simply plugged onto the three  6-poles pinbar of the HSI-88.

 

The HSI-88 operates event-driven: any changes on the tracks are reported immediate to the PC. This saves substantial PC resources and reduces the response time considerable because the pc has not to request cyclical about changes but gets all updated changes reported from the interface.

 

Each High Speed Interface HSI-88 will be supplied with a detailed operating- /assembly-instruction.

If you want to use an own written model rail way software for the communikation with the interface HSI-88 you can find the relevant commands in the file hsi88_befehlssatz_engl.zip (size: 13KB).

  The High Speed Interface HSI-88 is available as low cost kit, as checked finished module or as checked finished module in a case:

Each Interface HSI-88 comes with a  9-pole pc-connection cable.
