Furuno baud rates

[wguinon]

I am interfacing a Standard Horizon VHF to my Furuno 1623 radar but the manual doesn't give allowable baud rates on the I/O ports or describe their setup. Is this an omision or does it imply that the input baud rates are automatically detected and setup?

[Paul L]

The manual states
NMEA 0183 Version 1.5/2.0/3.0, 4800 bps

wguinon,
Paul has answered your baud rate question....(like most marine electronics of its design, it uses NMEA 0183 at 4800 baud)
But...

But, I'm curious what information you are trying to display on your 1623?

'Cuz, other than your position data, I can't imagine there is any NMEA data coming out of your VHF radio, that the Furuno 1623 will use / accept / display?
(if your VHF radio has a built-in GPS, or it passes your GPS position data in/out of it, you could input your NMEA position data to your 1623, but that's about it...fyi, the 1623 can use GGA RMC RMA or GLL NMEA position sentences.)

You do realize the Furuno 1623 is a radar display, which can also display some "nav data", it is not a full Multi-Function-Display (MFD), and cannot display any AIS targets, yes?



I hope this helps?

Paul ... Thank you for the baud rate info.

In a dense archipelago the close spaced islands tend to look all alike due to the limited resolution supported by a small scanner. I intend to send a waypoint from my Raspberry Pi running OCPN to the radar to help me align the radar image with reality, The Furuno 1623 uses ownship and waypoint LL to place a lollypop mark over the radar image of the waypoint.
I think of this as a poor man's radar overlay as found on certain MFDs. Instead of superimposing the radar image on the chart, this will superimpose the chart data on the radar image.

Summary description of my comm network:
380,400 bps from GX2200 to RPi via an FTDI RS422 to USB adapter; comprising AIS
DSC and RMC sentences for display.
4800 bps from GX2200 to Furuno 1623 radar GLL for ownship position
4800 bps from RPi to Furuno with waypoint position; BWR sentence

Walter,
How cool.

Yep, I'm familiar with the Furuno TLL I/O, I just never knew of anyone using it.
And, never thought of OCPN on a Pi, and using the 1623...
So..

So, that's all cool...
Congrats!


Fair winds.

pretty normal to send route data to a radar. it's just gps data output from a plotter at 4800 baud

ais is also nice on radar but since it's 4800 only I guess that radar does not take it.

smac999,
Yep, I'm aware of overlaying routes and/or waypoints onto radar....I've been doing that for decades....
What surprised me was that someone was using the Furuno TLL function, on a 1623, to place waypoints on its display....especially thru his VHF radio....and coming from OCPN, nonetheless...
Pretty cool...

Walter did / does something that I haven't seen others do with a 1623...

And, no the 1623 is not capable of displaying any AIS targets....but...

But, if you had an AIS Buoy's / AIS Nav Aid's coordinates, you could place that on the 1623's display, just like Walter is doing (using the Furuno TLL functions) when placing his waypoints in the 1623....
As, you could do this with any "fixed" point...


As I've said often, it's nice to learn something new!

Fair winds.
