S88-4 English
After branch connections of a data line, seen from the control unit or
the interface, you can use S88-4 modules only.
Example for the combination of standard modules and S88-4 modules in one bus system. The
standard modules can be used in data lines directly connected to the control unit or the
interface only and not in branching data lines.
Earth connection
In systems with continuous mass (e.g. 3 rail systems fed with boosters
with continuous mass) the earth connection between s88 feedback
module and other components is made via the earth line in the s88 bus
cable.
In digital layouts with boosters galvanically separated, the earth
connection X2 of the S88-4 module has to be connected to a separate
earth line or to mass of the rails. This applies especially to layouts with
DCC conform boosters, but as well to layouts controlled by the central
station of Märklin** or the Ecos of ESU**.
