OK another issue, help file shows the following. However am on land and cannot place the boat
over my loc'n so cannot prove gps
signal ? all is ok as per the instructions except cannot verify, so assume that it only works if you know exactly where you are ? and place the boat
there, which is very odd indeed.
There is a small LED located on the BU-353. If the LED is off there is no power
being received. Check the connection.
If the LED is solid it indicates the BU-353 is searching for a GPS
signal. Try moving the GPS receiver to a clear location.
If the LED is flashing it indicates the BU-353 has a position fix and is transmitting data.
Try viewing the NMEA
data stream in OpenCPN
. Choose Options→Connections→Show NMEA
Alternatively, a diagnostic program is included on the installation
CD called GPSInfo.exe. Launch this program to install the diagnostic utility.
If it appears that the NMEA data stream is being received, the most likely issue is that OpenCPN
is not centered over your location. Click AutoFollow to center the map at your GPS location
