LDT's High Speed Interface for S88 feedback modules.

The HSI-88 comes with a 9 pin serial cable, and is as far as I know wired “1 to 1”. If your computer does not feature a serial device you can use an USB to Serial adapter which ist mostly mapped as “/dev/ttyUSB0” under Linux and as “COM3” or “COM4” under Windows.

<digint iid="hsi88-1" lib="hsi88" device="/dev/ttyS1">
  <hsi88 fbleft="1" fbmiddle="0" fbright="0" smooth="true"/>
</digint>

The smooth attribute is to prevent signal jitter due to the very fast read cycle of the HSI-88. If activated the signal will only change in 100ms cycles which is fast enough for Rocrail's automatic engine.

Mostly the HSI-88 is used as a second interface for sensor reading only. Therefore it is necessary to set the iid attribute to link sensors in the plan xml file which is described in chapter Multiple Controllers.

Windows only.

Select the HSI88 USB type.

The HSI88-USB communicates not by a serial device but by file.
The first connected HSI88-USB will have the following file name:

\\.\HsiUsb1

The number at the and of the file name will be increased by one for the second HSI88-USB and so on.
