9.3.5 DIP switch configuration when

installing Ekip Signalling 10K module
At installation, the module must be con-
figured to communicate via Local Bus or
Link Bus.
With communication via Local Bus, a
120 Ω termination resistor must be in-
serted on the communication lines. This
120 Ω termination resistor is switched to
the ON-position by the DIP switch 1 posi-
tioned on the upper side of the module:

The Ekip Signalling 10K module config-
ured for a basic module 10K-1 is already
done in the factory; configuration is done
with the DIP switches 2 and 3, both are in
OFF-position, see the Fig. 4.14. The DIP
switches are positioned on the upper side
of the module. The following tables de-
scribe the possible configurations, 10K-2
and 10K-3 configurations are not available
for Bypass-Isolation automatic transfer

Fig. 9.9 Ekip Signaling 10K module; When using a local
bus, the 120 Ω termination resistor must be switched
to the ON position with DIP switch 1. By default,
the Ekip Signaling 10K module type is already 10K-1
position (= DIP switches 2 and 3 are on OFF-position)
NOTE! The operational configuration is
read only at power on. Therefore, if the
module is on, it must be turned OFF and
ON in order for it to recognize a new
configuration.
