English s88-BiDiB-Link
6. Connecting the s88-BiDiB-Link
Connect the s88-BiDiB-Link via RJ-45 patch cables to the s88 modules
or the BiDiB knots. For the sake of clarity, we recommend to use
different coloured patch cables for different types of bus lines, e.g.
 green for the BiDiBus,
 blue for the s88 bus.
6.1. Use as a s88 interface
Connecting the s88 bus lines
You can connect a maximum of 512 earth contacts to each of the three
s88 connections, or worded differently:
 32 x 16-fold feedback modules or
 64 x 8- fold feedback modules.
When connecting s88 feedback modules not providing a RJ-45
connection according to S88-N but only a 6-pole plug connector, you
need an additional adapter S88-A. These are available in different
versions for various mounting situations.
Settings
In order to transfer feedback data from the inverface to the PC in HSI-
88 mode, you have to insert a short circuit jumper on JP3. As long as
the connection is open, data are transferred according to the BiDiB
protocol.
Please note: When using the s88-BiDiB-Link simultaneously as a s88
and a BiDiB interface, you have to choose the BiDiB protocol for the
data transfer (to keep the connection JP3 open).
