Finally getting my Pursuit back the water and realized that neither Simrad: NX40 nor NSS8 is communicating with my Standard Horizon 2150.
…I know the NX40 has a couple of issues but got the NSS8 working on the other boat.
Then i remembered this was a replacement NSS8…and all my settings would have been lost. After a quick search i found the very very good Standard Horizon documention (see below) but those were the settings were still on the radio from before i parked the Pursuit.
After a LOT more searching turns out the Simrad defaults to not transmitting NMEA and that too needs to be turned on…and the settings changed to match the 2150
