I'm totally confused about how I attach all these nav instruments
together for maximum flexibility. I'm planning on using a
MiniPlex-42BT to multiplex them all together, along with a Dell Axim
X51V PDA and a laptop, both via bluetooth, as a chart plotter using
the FUGAWI Marine ENC Windows and PDA software.
I've got:
- Garmin GPS (NMEA Talker (and Listener?) What about Garmin Mode?)
- JRC Radar 1500 Mk2 (NEMA Listener)
- VHF Transceiver (NMEA Listener and Talker)
- NASA AIS Engine [NMEA Listener and Talker)
- Backup VHF Transceiver (NMEA Listener)
- Tillerpilot ST1000 (SEATALK Listener (and Talker?))
- Raymarine ST40 Wind (SEATALK Talker only?)
- Raymarine ST40 Bidata (SEATALK Talker only?)
- Raymarine ST30 Fluxgate Compass (SEATALK Talker only) (haven't
purchased yet)
- Dell Axim X51V PDA (NMEA Listener (and talker?)) What about Garmin
Format?) -- via Bluetooth
- MiniPlex-42BT NMEA Multiplexor (not purchased yet)
So I think that breaks down to:
NMEA Talker = [GPS] [VHF] [AIS] [SEATALK IN]
NMEA Listener=[gps?] [RADAR] [VHF] [VHF2] [AIS] [TILLERPILOT] [WIND?]
[BIDATA?]
SEATALK=[TILLERPILOT(L/T?)] [WIND (L?/T)] [BIDATA (L?/T)] [COMPASS
(T)]
BLUETOOTH = [AXIM X51V] or [LAPTOP]
Do you see a problem with the config? How does the Tillerpilot ST1000
receive steering commands/waypoint data/other data from the PDA that
is transmitting NMEA? That's my main concern; how does the PDA, GPS
and Tillerpilot interact in the above config? I'm assuming I'll be
running the MiniPlex-42BT in hub mode?
Another big question is do I need the ST-30 Fluxgate Compass when I
have the Tillerpilot, as it also contains an internal fluxgate
compass? Does the Tillerpilot output compass data on SEATALK and/or
NMEA?

Hi,
Have a look here too:

5 input channels, including one for AIS.
If you want an elegant Bluetooth solution for hooking up the multiplexer,
