3. Connections
The AS07-N2K sensor has the following connections.
•
NMEA 2000 port
. The AS07-N2K is powered by the NMEA 2000 bus and sends positional and
heading data (PGN messages) through the NMEA 2000 bus, to be available to all connected
devices.
•
G 3/4 thread
for connection to chosen base.

NMEA 2000 - Connecting to the NMEA 2000 network
The AS07-N2K sends positional and heading PGN messages, through the NMEA 2000 bus, to be
available to all connected devices.
The AS07-N2K is pre-fitted with a five-core screened cable for the NMEA 2000 connection, fitted with a
male micro-fit connector. Simply connect the cable to the network backbone using a T-piece connector.
It will work immediately once connected to a powered NMEA 2000 bus.

NMEA 2000 is a serial data network operating at 250 Kbit/second utilizing the Controller Area Network
(CAN). The NMEA 2000 network allows multiple electronic devices to be connected together on a
common channel for the purpose of easily sharing information. Because it is a network, and because
multiple devices can transmit data, a comprehensive set of rules dictates the behavior of the network
devices. The CAN automatically provides some of these rules for control of access to the network,
packet transmission, and for error detection.
Similar to NMEA 0183, NMEA 2000 defines standard data formats and definitions, but in addition
provides more extensive network management rules for identifying nodes on the network, sending
commands to devices, and for requesting data. Besides the greater amount of control and integration
provided, NMEA 2000 replaces with a single cable the wiring of up to 50 NMEA 0183 interconnections
and can handle the data content of 50 to 100 NMEA 0183 data streams.
4. AS07-C: Using the Optional Output Switch
The AS07-N2K is designed to be used out of the box, for instant positional data to your NMEA 2000 bus.
Alternatively, the AS07-N2K can be used with the AS07-C (optional purchase) for,
