• HSI-88-USB (Deprecated)

LDT's High Speed Interface for S88 feedback modules.

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.

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.

Number of 16-Port modules connected on each chain.

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.

Option for DIY compatible devices to disable hardware handshake.
