 The S88 bus is a feedback bus system for model railroad systems.
 Up to 32 decentralized slaves connected to each other in a serial fashion controlled by one master device (control unit). The slaves are spreaded around model railroad layout.

 Netzer with installed IO firmware (at least Release *1.5pro*) must be configured via the webinterface:
   - SPI-Master-Mode on the common page (restarting Netzer afterwards is needed)
-  - SPI-Master-settings: Frequency on 5 kHz (for long lines also 1.3 kHz may be tried), SPI mode 2 (Idle state of the clock signal is 1, data is stored on falling edge), sampling of the data in the middle of clock cycle (see picture)
