3. Operation overview

The interface ZEUS can be used as a

PC interface for the s88 bus and/or

BiDiB interface
Use as a BiDiB interface
You can connect a maximum of 31 additional BiDiB knots to one interface ZEUS via two RJ-45
sockets. The assignment of the BiDiB knots to the two RJ-45 sockets is optional.
Use as a PC interface for the s88 bus
The interface ZEUS has three RJ-45 sockets according to S88-N for the connection of three
s88 bus lines.
Background information: The standard s88-N regulates the assignment of
commercial Ethernet patch-cables for use in s88 feedback systems. Unlike the 6-
conductor connecting cables frequently used, the patch-cables used in computer
networks are screened against outside electric signals. Thus using patch-cables reduces the
liability to interference considerably.
ZEUS | s88-BiDiB-Link
The interface (ZEUS) provides the
connection between PC control,
s88 modules and the BiDiB-nodes
on the different levels of the
system. The hub (BiDiB node 2)
provides an additional level.
BiDiB-nodes have different
functions, e.g.: feedback modules
(class "Occupancy") or stationary
decoders (class "Accessory
Control").
In contrast to conventional digital
control systems there is no need
for a digital control unit and a
booster for this BiDiB controlled
layout part.
