§
After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges and short circuits created
by accident. This would cause faulty operation or, in the worst
case, damage. You can remove excess solder by putting a clean
soldering tip on the spot. The solder will become liquid again and
flow from the soldering spot to the soldering tip.

4. Operation overview

The module is compatible with all components working with the s88-
bus developed by the company Märklin**. It can read in 16 earthed
contacts. This information is transferred via the s88-bus to the next
module or to the connected digital unit (interface, memory or central
unit). The data transfer from one feedback module to the next one
works on the principle of the bucket brigade device.
To each memory unit of Märklin* can be connected in series up to three
and to an interface unit up to 31 feed back modules. If connected
directly to the central unit up to 52 feed back modules can be
connected depending on the type of central unit.
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 so far, 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 customary feedback modules
the module has an additional connector for a 6-conductor connecting
cable. Alternatively, the module´s RJ45 connector can be connected to
a 6-pole connector of digital devices or customary feedback modules via
a special adapter (optional extra).
