English s88-BiDiB-Link
Use as a PC interface for the s88 bus
The s88-BiDiB-Link has three RJ-45 sockets according to S88-N for the
connection of three s88 bus lines.
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.
You can connect to each of the three RJ-45 sockets 512 earth contacts
or
 32 x 16-fold feedback modules or
 64 x 8-fold feedback modules,
which corresponds to 1536 feedback sections in total.
For the data transfer to the PC you can choose between:
 HSI-88-mode. Hint: It is used the HSI-88 protocol for serial
interfaces, not the HSI-88-USB protocol.
 BiDiB-protocol. The connected s88 modules are administered as
BiDiB knots by the interface.
Use as a BiDiB interface
You can connect a maximum of 32 BiDiB knots to one s88-BiDiB-Link
via two RJ-45 sockets. The assignment of the BiDiB knots to the two
RJ-45 sockets is optional.
Simulaneous use as a s88 and a BiDiB interface
It is possible to use the interface simultaneously as a s88 interface and
a BiDiB interface, there are no restrictions according to the number of
s88 modules or BiDiB knots to be connected. In this case data transfer
to the PC according to the BiDiB protocol is mandatory.
