Garmin GPS 128 Interface to Autohelm 3000
 

Looking for advice / suggestion / experience on interfacing a Garmi n
128 GPS to an Autohelm 3000 autopilot.

Is it do-able, and what do I need? Are cable interfaces ommercially
available?

Regards,

Syd Turner

According to the Autohelm 3000 Wheel installation manual I got from
www.raymarine.com, you need a "Z075 - NMEA format Radio Navigation
Interface", which the picture shows plugs into the control box of the
AH3000. It uses NMEA 0183 crosstrack error statements (data) to correct
its steering. Once you have this little, probably unavailable, box plugged
into the AH3000, you plug the Garmin's data out wire into the NMEA data in
on the box and hook up the grounds (NMEA - connections) of both. The
Garmin has a data output control in the MENU part of it and you would set
data output to NMEA 0183 at probably 4800 baud and you're in business.

I find no manual for the interface box, other than the reference in the
AH3000 manual. This manual is on:
http://www.raymarine.com/raymarine/D...=3&Page=657&Pa
rent=166
(paste the two lines into one that got wordwrapped.)

Now, at the bottom of the Autohelm manual list, there is a reference to
another converter box called "Autohelm NMEA Bridge (Z290)"
I downloaded the manual for THIS box and it lists under its conversions and
hookup diagrams Your AH3000. You would hook the NMEA out of the Garmin to
the NMEA in on the NMEA Bridge Z290, then hook the Z290's Seatalk output to
the AH3000 seatalk connections on the back of the control panel. THIS box
will also allow the Garmin, or a PC serial port with nav software, to
control the AH3000. Check around to the dealers who've been in business a
long time. They might have the box all covered in cobwebs in the storeroom
and be willing to part with it for a few dinar.

Without the box to convert NMEA into Seatalk for AH3000 control, it won't
happen. Sorry.

I asked Raymarine about the availability of an interface box for the older
AH3000's and the ST buss. I don't remember the part number, but if it is the
same one that Larry mentions, it doesn't work with the older "compass rose"
version of the AH3000.

Syd,

If the AH3000 you have has NMEA input (I know this exists in the 3000+
but am not sure of other) you are set already.

If it has a Seatalk input (it should) then go to Peter Bennett's site
http://vancouver-webpages.com/peter/idx_nmeaprog.html and
Find: NMEA capture and hardware - then
Find: NMEA Hardware and look around -
I remember one of the manufactures offers a box that has Seatalk
capability, but O don't remember much more than that.

It is going to cost 3-400$us but it is worth it.

You will end up doing some wire-by-number by yourself.
You will also have to setup the Garmin for NMEA output.

Larry,

Thank-you for the info. Probably worthwhile trying.

Now I'm on a quest for this Z290 BOX.

All the best,

Steve,

Good point. Mine is the AH3000 wheel unit as opposed to the analog
wheel unit.

Is it the analog unit that yo urefer to as the "compass rose" version?

Cheers,

Syd

Matt,

Thank-you for the update.

It looks like Brookhouse offers Seatalk capability.

This is a standard Raymarine product, any dealer should be able to supply
you wih this.

It does, but only one way: from Seatalk to NMEA. You need conversion in the
other direction and as far as I know, none of the available NMEA
multiplexers offer this. You definately need the Z290 box.

An alternative is to get a ST-60 Multi display, this has NMEA input and
output. In other words, you spend more but you also have a NMEA/Seatalk
repeater... In the Netherlands the RSP for the multi is € 491,60 and the
Z290 is € 204,20 (ex vat). Your mileage will vary according to your
national distributor... This way, for "only" € 286 you gain a repeater.

See
http://www.raymarine.com/raymarine/S...ts/60Multi.pdf
pages 8 and 9 for the sentences that it sends/receives from NMEA.

Rediculous pricing, isn't it? The Z290 cost around $160 in the US. That
equals around 130 euro....
