If your NMEA 0183 Listener is not showing any data when connected to the NMEA 0183 output of an NGW-1, the first step for fault finding should be to see if the NGW-1 supports the conversions you need...

NGW-1 firmware v2.500 and newer. Switching between AIS and Standard configurations does not require the firmware to be updated, as Actisense Toolkit can help create the exact configuration by enabling or disabling conversions as required. Please refer to Page 9 for details of how to configure an NGW-1 using Actisense Toolkit...

When there is more than one device of the same type (like a GPS) on the NMEA 2000 network, the NGW-1 will use the data from the highest priority (lowest source address). If the device you'd rather use as a secondary Talker for the NGW-1 claims a lower source address then unfortunately there is no easy way to change this. The first step would be to try changing the device..

NMEA 0183 Output. It is perfectly acceptable to connect up to eight devices to the NGW-1 NMEA 0183 output provided that they are all individually electrically isolated, depending on the electrical demands from each device. However, please check with your device manufacturers that you do not have more than one device that does not have an electrically isolated input...

The only NMEA 0183 sentence that is currently used for engine data is RPM, so it is impossible for any manufacturer to create a conversion from NMEA 2000 to NMEA 0183 for all of your engine data...

To be compatible with the DST-2, your transducer must be piezoelectric depth transducer crystal element using a three wire interface...

The typical maximum depth range of the DST-2 is 100 metres. The minimum detectable depth of the DST-2 is typically 0.5 metres – which makes it one of the best in the world. The true minimum depth that is detectable depends far more on the depth transducer than the DST-2 because it is the transducer 'ringing' that determines the earliest opportunity that a returning echo signal...

To get NMEA 2000 data from your legacy depth, speed or temperature instruments you may wish to use a DST-2 connected to the input of an NGW-1...

..The DST-2 frequency is dictated by the hardware components. Which means it is unfortunately not possible to change it by installing different firmware.

The CAN connections on the DST-2 were designed for an OEM customer that only required a basic CAN connection. As the DST-2 CAN connections do not meet the strict requirements of NMEA 2000, it is not possible to certify or market the DST-2 as an NMEA 2000 product...
