2. NW6010 Bridge Control Unit
2.1 General
The Bridge Control Unit (BCU) serves both as an interface for serial/NMEA data as well to display
the operational status and provide user functionality like, but not limited to, operational
performance tests.
2.2 Location and mounting
The BCU may be mounted in a protected environment at any convenient location taking into
account the compass safe distance as indicated on the unit.
2.3 Indicators
The BCU has 1 LED at the back to indicate that the power supplied to it is present, in other words,
at least a PoE link is established to the core module. In the event the LED is illuminated (steady,
green), the video display on the unit must work.
Furthermore, each network-port provides Link and Activity LEDs on the backside of the unit with
following meaning.
Link speed (Green LED); the LED is on when there is a link connection, otherwise, the LED is off.
Activity (Yellow LED); the LED is flashing when there is activity on the link; otherwise, the LED is
off.
2.4 Errors
Error indication: in the event the LED on the back side of the unit is On, the display is illuminated
and showing text (buttons), but no valid (UTC) time is presented on the display, the data-link to
the core module is not functional at that time. All other errors are presented on the display.
The BCU provides an Auxiliary ALERT relay of which the (dry) contact rating is 28V dc, 200mA
max. During a correct functioning of the VDR, the relay contacts are in the NO position. When an
ALERT condition occurs or the VDR loses its power, the NC position is valid. (NC=normally closed,
CO=COMMON contact, NO=normally open).
2.5 Operating instructions
The BCU is equipped with a touch screen display with day and night display mode.
