Power connection
The unit has no power key and will turn on when power
is applied.
When used in an
NSE/NSS system, it
is recommended to
connect the BSM-2 to
the Power control bus,
and set display system
to power control
master.
If the BSM-2 is connected
directly to the vessel’s
battery, the module will
continue to draw power even
when it is not in operation. It
is recommended that the
yellow power cable wire be
fitted with an optional on/off
switch, allowing the BSM-2
to be powered off when not
in use.
