[CA] Wireless wind to Axiom via Micro-Talk Gateway

[galacticair]

I’m thinking of expanding an existing Raymarine/TackTick wireless system that has:
- Speed/depth transducers with hull transmitter (T121)
- Dual display (T111)
- Racemaster (T070)

Specifically, I’d like to add:
- Wireless wind transducer (T120)
- (Likely) Wireless mast rotation compass (T221) since we’re on a multihull with a rotating mast
- Axiom MFD on a NMEA 2000 backbone

A few questions come up as a result:

(1) What’s the best way to bridge Wireless MicroNet wind data to NMEA 2000? Which of these two options performs best? (in terms of data lag on the Axiom MFD).
- I read this very helpful post “Adding a wind data source to a Axiom” (http://forum.raymarine.com/showthread.php?tid=4060). The two recommended approaches that apply to Axiom MFDs are:
(1a) “Install... T122 Wireless Interface, and a NMEA 0183 to NMEA 2000 data bridging device (ex. Actisense NGW-1)”
(1b) “Install... a Micro-Talk™ Wireless Gateway”

My thoughts:
(1a) adds an extra conversion step and failure point since it is MicroNet (T122) -> NMEA 0183 -> NMEA 2000.
(1b) sounds the simplest since it is direct MicroNet (Micro-Talk Gateway) -> SeatalkNG / NMEA 2000.

I imagine the answer of what's best depends on the relative performance/lag of the T122 vs. the Micro-Talk Gateway… Also, the T122+Actisense adds an extra step since it converts MicroNet -> NMEA 0183 -> NMEA 2000. The Micro-Talk Gateway converts directly to NMEA 2000.

I’m also thinking ahead to a world where I may add more SeatalkNG / NMEA 2000 sensors (e.g. precision compass) => so I care about lag in both directions (from and to MicroNet)

Also, is there any risk of data loops in either approach? I can see a future with 2 heading sources (1 NMEA 2000 precision compass, 1 RaceMaster T070), and up to 3 GPS sources via NMEA 2000 (2 MFDs, 1 VHF with GPS). The ActiSense may better allow me to manage which data is passed around…
