I'm installing H5000, and plan to connect it to a miniPC via the WIFI-1 module (so that I also have an option to calibrate H5000 from iPad), and then run Expedition on the miniPC.

Several threads on this forum talk about the "problem" of how H5000 doesn't have GPS or AIS and data to share, and thus suggest the following steps
1. H5000 to PC (directly via Ethernet or indirectly via WIFI-1 module)
2. Set the Expedition settings to get instrument data via H5000 websockets but NOT get GPS data from H5000
3. Install NGT-1 (Actisense NMEA to USB device) to get NMEA into PC
4. Set the Expedition settings to ignore any instrument data received from NGT-1
... on the basis that this approach has lower latency than getting AIS & GPS data from other indirect sources.

However, I have a NAIS500 that is the primary source of the AIS data that it then broadcasts on NMEA2000 and in serial via a USB output. Given an NGT-1 costs £150+ installation and a UBS lead costs only £1, and given no latency at all (NAIS500 is the primary source of AIS data, which must be faster than conversion to NMEA and back again), can I streamline the above by replacing steps 3 & 4 with
3. Connect NAIS500 to PC via a USB lead to get AIS & GPS serial data

In particular, can anyone confirm whether the NAIS500 shares over USB all the things Expedition needs-but-can't-get-from-H5000, presumably a) GPS data on my vessel, and b) AIS data on other vessels ... but is there anything else needed?
