GNSS splitter

The GNSS splitter (Global Navigation Satellite System) is used for connecting the GNSS
antenna and the splitting and distribution of the received GNSS signal (e.g. GPS, Galileo
or Glonass) to two BSCUs. The GNSS splitter is always installed in the connection and
control panel, even if only one BSCU is used.

AC Power Distribution Module (APDM)

The AC Power Distribution Module (APDM) is used for connecting the voltage supply and
the voltage distribution to the backplane and the installed hardware components. The
APDM is used for the V
Supply Unit (PSU), converted to the required operating voltage, and subsequently distrib-
uted to the backplane and the installed hardware components.
With redundant voltage supply feed, two APDMs are installed (optional). The redundancy
options of the voltage supply are described in
supply" on page 62.
The following figure shows the top view of the APDM. The following table describes it in
detail.
