Micro Termination
Resistors
Two termination resistors are required
on every NMEA 2000 network, one on
each end of the trunk line. Normally,
a male termination is used since male
pins tend to point back to the power
source. In cases where the gender is
reversed, a female terminator may be
required. The inline terminator is used
where the network is terminated at a
product, for example a GPS or weather
station at the top of a mast.
The Bulkhead Feed-Thru allows ease of
installation through panels or bulkheads
and establishes future connection points
in a network installation. The bulkhead
feed-thru also maintains the integrity
of watertight bulkheads by providing a
waterproof seal and connection.

Feed-Thru
Features rugged keyways for
positive alignment of connections
Multiport boxes allow several drop
cables to be consolidated and
connected back to the trunk, which
eliminates the need to have numerous
tees connected near a single point.
Multiport boxes connect back to the
trunk through a double-ended cordset
and Tee.
•
Ideal for consolidating many
connections; for example behind
dashboards
•
Requires the purchase of an
additional double-ended cordset
for connection back to the trunk
Waterproof rated to IP67
