If it's like my Furuno you'll simply need to get a Garmin cable and connect

Is that sufficient to support the so called "ARP" plotting functions,
or do you also need a flux gate compass to provide heading
information?

No, ARPA functions are much more complicated that the simple NEMA
interface on the small commercial Furuno Radars. You need an compass
input to get the Waypoint Popsicle on the Radar Display. ARPA takes a
complete ARPA Unit which is a complete cpu based system that is in
addition to the basic radar display system.

I'm under the impression that ARPA is included on the Furuno 1833 that
I've been considering. Is that not correct? I would like to be able
to eliminate the flux gate compass requirement by assuming COG =
heading but not sure if it's possible.

The ARP11 (10 target ARPA) is listed as an option for your radar. As far as
the data connection between the GPS and radar, if the Garmin cable is the
same as most of the others they make it would have some un-terminated wires
plus the red and black for power. You need the NEMA data cable for the radar
(the one with the bare ends). Nothing more then connecting 2 wires from each
cable and setting up the data outputs and inputs on each unit. Sorry I can't
remember the colors you need to connect and the info is at work.

I am under the impression that ARP is and add on option for all the
small commercial Furuo Radars. I am not 100% sure on that exact model
(1833) but I bet Doug could give us a difinitive answer. Any add on
option is going to cost BIG BUCKS, however and probubly not worth the
cash for a noncommercial users. The standard NEMA input for these type
Furuno Radars is to display the Position Information, Speed, Course over
Ground, and Next Waypoint Bearing and Distance, at the bottom of the
screen in the NAV Info Position. If you want the Waypoint Popsicle to
display on the screen, then you must input Compass Data on the Gyro
Input, and that is a seperate connection from the NEMA Input. All the
Furuno's I have dealt with will NOT accept Compass Data from the NEMA
Data Stream, but only on the Gyro Input.

Using NMEA from my Garmin (Etrex Mariner or GPS 12) to my Furuno 1622 does
provide the Wapoint Popsicle, in addition to everything else.

Before I type and display my ignorance here about the ARPA issue, are we
talking about an 1830 or 1833? I see both mentioned in the trail.
IF I had an 1830 radar, I would want to make sure it has a version 08 or
higher EPROM and the revised modulator board in the scanner. Otherwise you a
prime candidate for blown modulator FETs. To determine the EPROM version,
turn on the radar and during the initial Time Delay before the radar can be
switched to transmit, the Resident Version of the EPROM is displayed on the
CRT. The last two digits on the right indicate the EPROM version. Version
08, 09, etc means an OK system. Version 07 and below, get the modification
done requiring a new EPROM in the display and new modulator board in the
scanner. Back in 1990 Furuno covered this as a warranty item. No idea if it
is still covered.
Compass input to the Furuno is via the gyro inputs and may be from their
AD100 conversion box or a flux gate compass, such as Furuno, KVH, etc. There
was a wiring change in mid production of the gyro connector, so make sure
you have your manual handy to match what you have.
As I see it, for an 1830, NMEA will give you lat/long, speed and
range/bearing to a waypoint.. It is not used for compass. Pin 3 of the
Furuno NMEA cable is receive data +, and pin 4 is receive data -.

Yep, that's how I remeber it as well Doug. I haven't seen an 1833 in
person, but my assumption (I know...Bad idea) is that the 1833 would be
the same. Maybe Furuno has changed the firmware in the 1833 to use
NEMA compass data, for generating the Waypoint Popsicle, but it hasn't
been the case in any of the previous models.

============================================

I just got back from the Ft Lauderdale boat show and had a chance to
talk with the Furuno factory reps. It turns out that ARP functions on
the 1833 are possible but require an optional circuit board that costs
about $600 or so. No where is the circuit board mentioned in the list
of 1833 options on the Furuno web site and several dealers I've talked
to were not aware ot it either. There is also an additional circuit
board available that accepts composite video input and allows it to be
displayed either full screen or in a window.

Yep, that squares with my memory. ARP is a seperate function that must
be added on to any of the small commercial Furuno Radars. Once you get
into the Big Boat Stuff it is built in, but the cost are significant.
