s88-BiDiB-Link English
1. Definitions
S88, HSI-88 and BiDiB are protocols for the data transfer between
model railroad layouts and PC.
S88
s88 is the most simple bus system to feedback PC conform data. At the
s88 modules´ inputs is determined whether they are connected to
earth or not (or in other words are closed or open). These feedback
data are transferred from the s88 modules via an s88 interface into the
PC where they are used as a basis for the PC control.
HSI-88
HSI-88 was developed to transfer s88 feedback data from a PC
interface with the possibiliy to connect three s88 bus lines into the PC.
BiDiB
BiDiB is a protocol which allows bidirectional communication
 among different components of a model railroad control (e.g. digital
control units, boosters, accessory decoders and feedback modules)
and
 between the components and the PC.
With BiDiB it is both possible to transfer feedback date via an interface
to the PC, and to send switching and control commands from the PC to
the components of the model railroad control.
