Troubleshooting Guide
This guide will concentrate on all relevant troubleshooting issues, that may arise on your NGW-1. Therefore, the cables
between the NGW-1 hardware and any other devices should be checked as a matter of course, before continuing with
this guide.
Status LEDs
The NGW-1 hardware has two bright LEDs that can be seen through the case to indicate when data is received from
either the NMEA 0183 device or an NMEA 2000 network connection. It is an important point to note that these two LEDs
can only show when their respective data is RECEIVED; it is not possible to show both transmit and receive
simultaneously on a single colour LED.
The NMEA 2000 LED indicates that messages in the Rx Enable list are being received from the NMEA 2000 bus.
The NMEA 0183 LED indicates that valid NMEA 0183 data is being received. Note that this data may not be in the Tx
enable list, so it is possible for the NMEA 0183 LED to ash without any data being transmitted to the NMEA 2000 bus.
The purpose of this LED is to assist with Baud rate detection and the correct wiring of the device.
These LEDs can be used to debug potential problems.
Behaviour Solution
USB only: The LEDs do not
light
The USB driver has not been installed correctly, refer to “USB Driver
Installation” on page 5
The NMEA 2000 LED does
not ash when the NMEA
2000 network is active
Check that the NGW-1 is connected to the NMEA 2000 network and that the NMEA
2000 network is operational refer to “Connecting to the NMEA 2000 Network” on
page 5.
Conrm that the PGN messages are available on the network (using an Actisense
NGT-1 or similar device) and that the required PGNs are enabled in the ‘Rx PGN
Enable List’ shown in NMEA Reader (refer to “Conguring using NMEA Reader”
on page 9.
The NMEA 0183 LED does
not ash when connected to
an NMEA 0183 Talker
Check that the NGW-1 is connected correctly to the NMEA 0183 device and that
the same Baud rate has been set on both devices. Refer to the relevant connection
option from those described on page 6 onwards.
Both LEDs ash together,
once every 10 seconds
Indicates that the NGW-1 is powered but no data is received from either connection.
If valid data should be present and converted by the NGW-1 on one or both inputs,
refer to the two rows above.
The LEDs ash alternatively
very fast (4 times per second).
This sequence repeats
continuously
Indicates that the NGW-1 has lost its Firmware, please connect the unit to the latest
NGW-1 Actipatch and re-install the Firmware. The latest Firmware can be found at
www.actisense.com/NGW-1/Downloads.php.

Technical Support and the Returns Procedure
If following the troubleshooting guide did not resolve the problem and an error persists, please contact Actisense
technical support to help trace the issue before considering the return of the product. If Actisense support concludes
that the NGW-1 unit should be returned to Actisense (refer to the ”Company Information” on page 12), a Returns
Number will be issued by the support engineer.
The Returns Number must be clearly visible on both the external packaging and any documentation returned with the
product. Any returns sent without a Returns Number will incur a delay in being processed.
