That's puzzling. The gps used is from the B&G Zeus 12 Touch, built-in. It has been quite reliable in getting us to our destinations.
I have Raymarine Seatalk
instruments which are connected to the B&G Nema2000 bus with a Raymarine
Seatalk/SeatalkNS converter and the output is wired directly to the Nema2000 bus. The ZeusT12 shows wind
and instrument data from this.
I have a gps puck
wired directly to my nmea0184 input on the DSC VHF
, which is totally independent from the B&G & instruments.
I have another Win10 bu353 gps puck
that I use with my MS Surfacepro3 and OpenCPN, but I removed that because I had gps from the B&G which was running. At first I was getting a double signal.
The way I get data into opencpn is via a german gadgetpoole seatalk
link, to nmea01823 with serial
converter to usb plugged into the single
usb port on the surfpro3. I did not have to use my usb/ethernet hub because I did not need the Gps puck or ais
The other end of the gadgetpoole seatalk link is directly connected to the three seatalk wires, but the device is galvanically isolated and powered from a 12vdc fuse and breaker. This bidirectional device is set up to not duplicate data already available.
The Raymarine Seatalk/seatalkNS converter is probably putting the ZeusT12 GPS signal onto the Seatalk bus and the gadgetpoole seatalk link is getting it to opencpn as nema0183 data.
The last day I turned on my autopilot. Was the 100mph seen before or after that? Was this found on a consistent basis?
several times when O failed and I had to restart, that the boat
was located far away and there was a red line off the screen for moment before the new gps signal came through.
Could this be what happened or is it more frequent than that?
