Furuno 1724C/NT - No NMEA Output

[foolishsailor]

Oh mighty horde I am betwixt a rock and a hard place...

Been through this with Furuno for a couple weeks now back and forth by email and no help yet...

My Chart Plotter/Radar (Furuno 1724c/nt) does NOT output NMEA on either of its two ports.

I have confirmed that the wiring is correct on all devices. Everything else works fine - it receives all NMEA data.

What this is preventing me from doing it outputing waypoint data like XTE, RTE to my autopilot so I can only use my AP to steer a heading versus to a Waypoint and compensate for things like XTE.

Anyone have this model or familiar with it? Furuno assures me it is supposed to output NMEA on the two ports but I have scoured the literature and it doesnt explicitly state that it does.

it only states that it outputs NMEA through its NETWORK port which doesnt help me since I am based totally on 4wire NMEA system...

help????

Yes, your unit outputs NMEA on port 1, 3 or the network port. You can confirm this by monitoring with a laptop computer running Hyperterminal or connecting the NMEA output to the input and using the port monitor function. You must have "Output Destination" set to YES (default is NO) in the installation wizard to get RTE and WPL sentences when navigating to a waypoint. Make sure you have the sentences you want set in the port setup menu.

Eric,

thanks for the info. Yea, I have hooked it up to hyperterminal and via the software that came with my multiplexer - and no NMEA coming out even with output destination switched to Yes.

ughh, looks like there is something wrong with the machine? Is that possible if it is receiving NMEA properly through the port but not outputting?

It's certainly possible the receive is working and the transmit is broken. I've experienced the transmit going out on a 1833c when there was a grounding problem between the 1833c and a SSB radio. Of course, Furuno blamed ICOM and ICOM blamed Furuno.

If you have a digital voltmeter, connect it to the blue-white and see if you notice the voltage bouncing around, if yes, then it's probably transmitting and you have a connection or protocol problem.

Page 20 of the manual shows how to connect it to a PC.

It may be that the setup for that nmea port needs to be completed, there is a page where the 'strings' to be transmitted are selected....

Hi, Any progress on your problems?

I have similar problems with my unit. Trying to output to a Raymarine ST60 Multi Display.

Which Wires are you using?
