The TackTick are wireless correct? Have to have some interface for the wireless set to join the 0183 wired world. Also, the TackTick use a variable data rate "MicroNet" protocol broadcasting on the 900MHz frequencies (varies by where instruments were sold) to move their data around. So, you'll need a MicroNet wireless to NMEA
wired card, which I think is the T122. About $400 as you said
We have Nexus on the current
boat, and I do use 0183 out of them, but IIRC (somewhat doubtful) they use a proprietary protocol between individual instruments, and only the network interface puts out NMEA. Definitely could be wrong on that, just what's floating in the back of my mind.
