1NK-80 INTRODUCTION
1.1 What is NMEA2000?
The NMEA2000 transmits data through Controller Area Network (Can Bus). It simplifies the
connections and enables information sharing among different devices through a single trunk cable.
Compared with NMEA0183 in “RS422”interface, NMEA2000 has better transmission reliability and
shares data easier in a network.
1.2 NK-80 Overview
NK-80 NMEA2000 adaptor (as known as NK-80) is a gateway between NMEA0183 electronic
devices and NMEA2000 device/network. NK-80 allows users to connect their existing NMEA 1083
devices to an NMEA2000 network.
The key features of NK-80 are shown as follows:
1) Extend NMEA0183 Devices into NMEA2000 Network
NK-80 is a gateway between NMEA0183 electronics devices and NMEA2000 device/network.
NK-80 allows users to connect NMEA2000 network with their existing NMEA0183 devices.

7
2) Conversion between NMEA2000 and NMEA0183
3) Support Latest NMEA2000 Sentences
NK-80 supports wide range of NMEA2000 sentences with latest NMEA association released
documents.
4) User-friendly Configuration Utility
NK-80 also provides a configuration tool which allow user to modify NK-80 baud rate and
manage/filter NMEA2000/NMEA0183 sentences easily.
5) NMEA2000 Certified, ensures product quality is reliable in most extreme conditions.
6) Fully galvanically isolated for electrical spike protection. Isolated power is provided through
NMEA2000 network, NK-80 requires no additional battery source.

3Configuring NK-80
With the help of AMEC NK-80 Configuration Utility, NK-80 can be configured with other NMEA0183
baud rates, flow rates and NMEA 2000 device instance. The software delivers also comprehensive
product information about your NMEA adaptor which is helpful for error diagnosis. For advanced
applications, users can also filter NMEA0183 / NMEA2000 output messages and display the
incoming NMEA 2000 sentences.
3.1 Connect NK-80 to your PC
Step 1: Connect NK-80 adaptor to PC through RS-232/USB and ensure power is available from
the NMEA2000 network.
*NOTE: PC connection is required for advanced configuration.
Step 2: Run AMEC NK-80 Configuration utility. In the window “Serial Port and Baud Rate Setting”,
there are 2 options to connect the software with your NMEA adaptor:
Auto: The system will scan all connected ports and their available baud rates and establish
connection automatically.
Manual: Configure baud rate and port manually. The default baud rate is 4800. Manually
enter port value and NMEA0183 baud rate. If the baud rate is unknown, choose Auto. Then,
click Connect to connect NK-80.
Click on “Connect”, to connect AMEC NMEA Configuration utility with NK-80.

3.2 Product Properties
3.2.1 NMEA 1083 baud rate setting
The tab PROPERTIES delivers complete information about the adaptor, which should enable a
better communication when technical support is needed:
NMEA 0183 baud rate: default baud rate is 4800 and can be changed with the pull-down menu
below with 4800, 9600, 38400 as options. After new baud rate is set, press “Apply” to confirm the
choice and the device will be disconnected automatically. To reestablish the connection, choose
the new baud rate and repeat the steps described in 3.1.
Figure 7 Properties Tab

15
3.2.2 Flow Rate Setting
The flow rate setting enables the users to configure how frequently received messages will be
transmitted. When flow rate is set to 0, received messages will be transmitted immediately. When
it´s set to 1 second, then received messages will be collected and transmitted every 1 second and
so on and so forth. Lowest frequency available is 5 second.
3.2.3 Device Instance ID
The adaptor comes with the device instance value set to 0 as default. If the adaptor is connected
to multiple of same devices on a NMEA 2000 network, you may find it necessary to set the device
instances of other devices of this type so that they are different.
The further options enable you to change the upper device instance or lower device instance fields
of the adaptor, provided that it supports modification of these fields over the network.
3.3 Filter NMEA0183 / NMEA2000 Output Messages
Step 1: At the CONFIGURATION tab, expand the message list on the left and click on a desired
message to configure.
Figure 8 NMEA Message Filtering
HINT: Double click to expand the message groups will show their message names.

16
Step 2: Once clicked on the desired message, the message properties will reveal on the right panel.
On the panel choose the needed attributes and click on Apply.
Figure 9 NMEA Message Filtering
Note: All message settings are enabled in factory default. The Default button restores all message
settings back to factory default.

3.4 Save NMEA0183 Output Message Log
Click on the NMEA0183 DATA VIEW (OUTPUT) tab to view message log history.
To record a log session, click on the disk button to start recording. The system will prompt you first
to save the log. It continues logging till the icon is click again.

NOTE: NK-80 configuration utility can only log NMEA0183 output sentences processed from
NMEA2000 messages.
