6.3 Power
This unit has 1x 100 TX PoE port, receiving 802.3af compliant PoE @48V. The total power budget
is 3.6 Watts. This device fully relies on the Ethernet PoE supplied from the Core Module without
which it will not operate.
6.4 Connections
The BCU allows for up to 3x NMEA (IEC61162-2) serial ports to be connected and recorded to
the VDRs Core Module. These will typically be used i.e. for GPS, AIS, etc. Data rates supplied
are up to 38k4 for all ports.
The BCU provides an Auxiliary CAUTION relay with a contact rating of 28V DC, 200mA max.
During correct functioning of the VDR, the relay contacts are in the NO position. When a CAUTION
condition occurs or the VDR loses its power, the NC position is valid. (NC=normally closed,
CO=COMMON contact, NO=normally open).
NMEA connections to the BCU are to be connected as follows.
Connector Data rate
N1 NMEA channel 1 A 4k8 ~ 38k4
N2 NMEA channel 1 B
N3 NMEA channel 1 Common
N4
NMEA channel 2 A
N5 NMEA channel 2 B
N6 NMEA channel 2 Common
N7
NMEA channel 3 A
N8 NMEA channel 3 B
N9 NMEA channel 3 Common
