I will check on Friday and get back to you. I thought that if I saw data streaming the connection was Open? Also looking at using an NGT versus the current NGW. I have a ticket into Actisense regarding the differences but it seems like that would allow Expedition to receive AIS data on that channel as well.
Thanks for the support!

My system uses a USB hub connecting a NGW-1 (to N2k) and a Simrad AIS to the laptop USB port. Racing last weekend we intermittently were losing AIS data and GPS fixes in Expedition. These were always at the same time with AIS going out for longer periods. The AIS is also connected to the N2k bus separately and we never lost any data on the chart plotter.
When we lost position I checked the raw data and could see position data from the NGW with data still streaming. When AIS was not available we had no raw data at all.
Any thoughts on troubleshooting would be appreciated.

Thanks for the suggestion, it worked with some caveats. Still need to use a Grib file that is time stamped so that drives the Expedition loaded tides. Went through the tide charts and found a similar time frame that I have a Grib for. Maybe not perfect, but enough to see current influences on the deliveries.

Just learning Expedition and was trying to look at a delivery route without wind influence. Attempting to understand current affects on route with different departure times but keep getting a No Wind at Start error. Is there a way to defeat this or fake it out at least?
