S88-3 English
4. Operation overview
The feedback module S88-3 is compatible with all components working
with the s88-bus developed by the company Märklin**. It can read in
16 mass contacts. This information is transferred via the s88-bus to the
upstream module or to the connected digital unit (interface, memory or
central unit). The data transfer from one feedback module to the other
one works on the principle of the bucket brigade device.
The number of feed back modules to be connected to one bus line
depends on the interface, the memory or the control unit in use. Please
follow the specifications of the device´s manufacturer.
Standard s88-N
The S88-3 has RJ-45 connections according to the standard s88-N,
which 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.
For the connection of digital devices or upstream customary feedback
modules the S88-3 has an additional connector for a 6-conductor
connecting cable. Alternatively, the module´s RJ-45 connector can be
connected to a 6-pole connector of digital devices or customary
feedback modules via a special adapter (optional extra).
