I have a new Icom M422 VHF and am trying to connect with a Garmin 182 GPS for the DSC function. I have contacted tech service both Icom and Garmin and it seems to be properly connected and all of the settings properly set. I only get a "NO POSITION" reading on my vhf when I go to ck it . I left it on for about an hour to see if it need time to initialize but still didn't work . Could it be that somehow they are incompatible with each other ? How can I check that? Also is it possible to check to see if the NMEA in/out are working on both sets?
Any help would be appreciated

interesting question, but I have no answer. Do you need to have
someone report a position to your VHF for it to show up? Or, do you
need to send out a distress call before your VHF will report your GPS
position. I'm curious to hear what others say about this.

Amen.
I have two Garmin's, two VHF radios and a radar. I had to email Garmin for
assistance in wiring for each of them. The good news is that Garmin is quick
to answer email.
I not only told them what equipment I was connecting, but quoted the
manufacturer's instructions, because they don't all use the same
terminology.
Remember to set the Garmin for NMEA/NMEA, and maybe not the fastest speed.
I found that my radar doesn't seem to detect the information at the fastest
speed, but is OK at slower BAUD speeds.
If it's a new Garmin, you may have to manually initialize it. When I travel,
my Garmin sometimes takes a long time to figure out where it is, so I
manually initialize it for the new location.

I just hooked up my JRC Nav 500 GPS to my Standard Horizon VHF. I pushed
the Nav button on the VHF and there was my position, speed, bearing and
date/time. Shouldn't need any sort of initialization and I would not
think the Garmin and Icom would be incompatible.
I find the designations used by the various manufacturers for NMEA data in
/ data out to be confusing. You never know if two different manufacturers
are describing things the same way. Its possible you just have the wires
hooked up wrong.
On my setup the GPS had DataOut + and DataIn +. These were the only two
wires I hooked up to the NMEA In / NMEA Out wires on the VHF.

The only other thing I can think of is matching the NMEA output speed from
the Garmin to whatever is spec'd for the VHF.

As for checking for a NMEA data stream, you can do this using a laptop
computer by using Terminal mode. Once again you will be faced with
connecting the correct GPS wires to the correct wires on a serial plug
that goes to the laptop. The manual for your Garmin should tell you which
NMEA strings it outputs. If the GPS is working its likely the NMEA output
is working so I'd concentrate on the connections to the radio.
Good luck.

Have you set the garmin to NMEA? Factory default is probably Garmin
protocol. Set it to NMEA and, if possible, select 4800 baud.

Check in the VHF manual (or ask support) which NMEA sentence is expected by
the VHF. Check if the GPS is configured properly (baud rate 4800, NMEA Out)
and make sure the version of NMEA that you have selected includes the
sentence that the VHF requires.

Under main set-up there is an option to change the interface set-up.
Change it to NMEA out.. don't think there is an option for baud rate.
This will get it going no problems.

I have the config set the way the Garmin tech. told me on COMM2 .The baude rate is not an option to change. The wiring config. should be ok because both the Garmin and Icom techs e-mailed me the wiring diag. and I feel comfortable that the wiring is ok. The connections should also be ok because I cut and spliced them about 5 times and still could not get anything.
I ck to see if the the gps is communicating with the vhf by pushing the "POS/DSC" button for a few seconds and it should show my position on the vhf screen but it shows "NO POS" whitch according to the Icom tech means the gps is not communicating with the vhf.

Nmea /dsc
 

Both the Garmin and the VHF have two ports.
The VHF has one to receive GPS info from the Garmin, which is displayed on
the VHF and transmitted with DSC, and another to send received info (from a
DSC reception) to the Garmin so that it will be displayed on the Garmin.

The Garmin instruction manual refers to them as Ports 1 and 2. One sends

getting back to Speckfisher's original post, is there a way to test
NMEA out/in with a meter, or do you need a laptop/software to do so?

With a meter you'll only see a fluctating voltage. It's easy to test with a
laptop and a serial cable. Start a terminal program, set it to 4800 baud, 8
databits, 1 stopbit, no parity, no flow control. Now you can tap in on every
NMEA signal. Let the laptop run on it's battery and you don't need galvanic
isolation for this test. Pin 5 on the 9-pin connector is ground, pin 2 is
the input to the laptop. Always connect ground first....

You can see if an NMEA device is outputting data using a voltmeter. I
prefer an analog meter, but DVMs can also work, unless they are very
slow reading.

Set the meter to read 5 volts, and, if there is data present, you
should see it wiggling - with the voltage varying around 2 - 3 volts.
The data line will acutally switch rapidly between 0 and +5 volts, but
the meter won't be able to follow it.

Luc,

Your laptop may have a treminal program installed already, but that may
not be the easiest solution.

You have two easy choices;
GPSUtility at http://www.gpsu.co.uk/
or
http://www.gpsu.co.uk/
both have real good NMEA input screens, but you have to get one (both
can be free), install it, and then find the NMEA input screen.

I just can't stand to stay out of this any longer, remembering the grief
I went through with Icoms and Raymarines and Garmins on
Lionheart....sorry....

I downloaded the Icom M422 manual and note on page 15 it, very casually,
mentions you need NMEA 0183 version 2.0 or 3.01 (and no others?) data
from your GPS, neither of which, of course, old GPS receivers will
generate with their version 1.0 or 1.1 NMEA 0183 generators.
No mention is made of what baud rate or bit stream or stop bit it can
read, so we'll assume 4800 baud 8-N-1 is compatible.....for now.

Now, over on the Garmin 182, now considered "obsolete" by Garmin and
their NMEA buddies, on page 98 they want to connect port 2, the green
wire, to the Icom's NMEA input lead some idiot colored RED just so
someone would try to use it for POWER IN, red being the color of every
other power lead in the boat. Idiots! So, Garmin's green wire to Icom's
red wire, and of course everything grounded together, you hope, so let's
connect Garmin's black "ground" wire to Icom's negative power lead, just
in case the Japanese have reverted back to their love of positive-ground
devices...something they just have never gotten over. Lots of Jap stuff
still has the case ground isolated from negative for "home use" in Japan.
This, in itself, might stop the data from showing up...

On page 73, it says the Garmin supports "standard NMEA 0183 data", making
no mention of what VERSION this data is
Oops...page 99. The Garmin is NMEA Version 3.0, probably close enough to
the Icom's 3.01 to get the data.

You NMEA subscribers...what's the differences between 3.0 and 3.01?

Ok....question.....HAVE YOU PUT IN YOUR MMSI INTO THE ICOM 422 FOR YOUR
BOAT? I believe you'll find DSC is DISABLED until a valid MMSI is
programmed in FIRST to the unit, successfully.

Let's start on pg 13 of the Icom manual and program in your MMSI,
CAREFULLY AS YOU ONLY GET TWO SHOTS AT IT! If you lock the unit screwing
around entering bogus MMSIs, the unit must be returned to Icom to reset
the processor before it will accept any more MMSI numbers, rendering it
useless to try to resell to another boater...another NMEA member feature
to maximize profits. With your MMSI in it...the radio becomes useless to
anyone else.

If you don't have an MMSI, don't go any further until you get one from
Boat/US or off your ship license from FCC....and program it into the
M422.

Ok, MMSI is programmed in, Garmin is on and locked to the birds, what do
you see on the Icom display? Is the little GPS sign blinking or solid?
Blinking means GPS data IS being received, but is invalid, according to
page 15, bottom right column of the Icom manual. Garmin puts out 3 of
the 4 sentences the Icom is looking for RMC, GGA, GLL. It should have
picked RMC first, no problem. No go?......

Hmm....Let's toss caution to the wind and connect the Icom's red NMEA
input wire to the Garmin port 1 green output wire and try it. Set the
Garmin port 1 to NMEA IN/OUT. Maybe port 2 is "bad", or the cable is
screwed. Won't hurt to look at the other port. Icom respond to port 1?

Although the Garmin's manual is written for 6-year-olds and makes no
mention of changing the NMEA output baud rate, I think you can on the
advanced NMEA page of the System tab. Try switching its NMEA output to
1200 baud and see if the Icom can see that, too.

Well? Let us know what you find out and if anything we've all said did
anyone any good.....thanks.

If you have a new computer, there won't be any serial port on it to play
with. USB has replaced old RS-232 and 422 ports on most all computers,
now, thank you manufacturers.

If you do have a serial port, a 9-pin serial port, you can hook the
Garmin to it by hooking the port 2 Garmin (green wire) to the serial
port's data input on pin 2 (pin 3 on the 25 pin old USB connector). The
pinout of serial RS-232 (and other info) is great on:
http://www.arcelect.com/rs232.htm

You can also buy a 9-pin serial port to USB converter cable for $50 from:
http://www.etronics.com/product.asp?...00&sbvname=293
or other places on the net. This is a way to get the archaic NMEA system
hooked to a new laptop computer with only USB ports on it so the nav
software will work with it.

Ok, Garmin green wire is hooked to pin 2 of the 9-pin serial port, Garmin
ground's black wire is hooked to pin 5 of the 9-pin serial port as shown
in the webpage's great picture. Now we need a "terminal program" to put
it on the screen for us.....

In Win XP click START - PROGRAMS - ACCESSORIES - COMMUNICATIONS and click
up HYPERTERM, Microsoft's dumbest dumb terminal program. Ignore it
asking you to make it the telnet program it wants to be, click NO. Then,
ignore it asking you to give it a name for this connection, click the
popup window's X to close it.

Click FILE at the top of Hyperterminal, then PROPERTIES to bring up the
New connection properties window. The Connect To tab is on top. Click
the arrow on the right side of line CONNECT USING and pick the com port
you're using. I only have COM3 on my Emachines mainframe. Ok, the other
stuff for dialup modems greys out and now click CONFIGURE button to bring
up the port settings page. Micro$not's system is too stupid to sync on
any com port speed, so you have to pick it. Pick 4800 Bits per second, 8
data bits, NONE parity, 1 stop bit and Flow control set to NONE so
Hyperterm ignores normal serial port flow control connections stupid NMEA
doesn't support. Click APPLY then OK. Click OK, again to close the
original popup window and at the bottom of the main Hyperterminal window
you should see:
Disconnected....Auto detect....4800 8-N-1...and some greyed out stuff.
If it says this, the screen will fill with NMEA sentences very rapidly if
the Garmin is talking to it. If it's working, click FILE then SAVE AS
and give it a name like GARMIN TEST PORT and a filename to save this
configuration to disk so you can just click it up next time you want to
look. Hyperterm is now listening to the COM port and typing whatever it
hears, even gibberish or binary gibberish or Garmin gibberish to anything
connected to it...at 4800 baud.

You now are using DOS 1.0's dumb terminal program from 1981...(c;

If you REALLY wanna see Hyperterm go crazy, pick one of the USB ports
something fast is connected to, like your USB mouse or webcam! It's all
gibberish...(c;

To give the grandchildren something to do, hook it to the USB keyboard
port so they can have type and read practice....

Did that help? I should be in tech support!...(c;

Hi,
Sounds like you are not making correct connections from Garmin to VHF
radio. This is a two wire connection, Garmin NMEA out and ground.
What is needed is to have Garmin interface set to deliver NMEA out via
its' cofiguration menu. Then all that is needed is two wires from
Garmin to VHF : These two wires should be within a screened cable
between the units.

1 NMEA out wire (probably blue) Check Garmin manual!! and
2 Garmin ground (probably black)
and to connect these two wires to VHF NMEA connection.
If correctly wired the position will appear on VHF as soon as Garmin
finds its position.

Twisted is also OK. For a short run, any cable will do.

finds its position.

Good point. If you don't have a fix or run the garmin in simulator mode, the
VHF will probably also say "no data". In simulator mode, a flag in the NMEA
sentences says it's simulated data.

Not the case with my Standard Horizon. I have done nothing with MMSI and I
was able to get position data from my JRC GPS onto the SH with no trouble.

I do have the MMSI in the radio and have checked my wiring countless times. Garmin emailed me back again and I was told to try to connect to COM1 and that should fix it ,but it didnt . The baud rate is not an option
to change on the Garmin . It will highlight but when I try to change it nothing happens. I have been waiting 2 days now for Icom to e-mail me back and tell me where to take the radio in for service. On the last e-mail the tech said if the wiring config. he gave me didn't work the M422 could be bad. I don't want to send it back to Icom if I can help it . I saw a Icom service center about 5 miles from my house I wonder if since the radio is so new if I can take it there.

He's not running a Standard Horizon. He's running a new Icom.

Larry,

While we don't have the 422 down here in Aus we do have other ICOM DSC
radios such as the 302 et al. They do not need an MMSI to be able to
digest the NMEA sentances from other gear (e.g Raymarine, Furuno etc).
My bet is the Garmin is at fault or the wiring to the radio. ICOM tends
to be pretty bullet proof!

Yes, I realize that but the way you wrote your statement sounded like you
thought it applied to all radios. I just pointed out that was not the case.

Just received an e-mail from Icom and the tech says that the Garmin GPS 182 must send the "GGA" sentence. I don't think that my 182 will send that because I don't see it in the manual. That could be my problem .

Hyperterminal is a terminal program, present on every windows system. You
can use that program to show NMEA data that is received on a serial port on
your screen. Hyperterminal is a pain to configure, especially if you're not
up to speed with serial data communications. So therefore I suggested
MPXConfig. This is a program I wrote to configure my NMEA multiplexers and
you can also use it to show NMEA data. It does the same as Hyperterminal but
it is preconfigured to NMEA (8 databits, 1 stopbit, no parity) and you can
set the speed right on the main screen to 4800 baud instead of disconnecting
first, dive into a menu and re-connect again as in Hyperterminal.

MPXConfig is free and can be downloaded from
http://www.shipmodul.com/downloads/mpxconfig2.11.zip

someone out there post there solution that is working.



http://www.garmin.com/manuals/494_OwnersManual.pdf
On page 96 of the Garmin 178C owner's manual, notice there are TWO data
channels in this unit Comm 1 and Comm 2. TX Comm 1 is, indeed, the blue
wire and TX Comm 2 is the green wire in the cable. Black is,
unfortunately, DC and data ground, same as my 185S.

On page 86-87, open MAIN MENU then COMM TAB and set the Garmin for NMEA
IN/OUT, not the proprietary Garmin data. If you don't have other Garmin
devices to talk to, set both ports for NMEA IN/OUT to avoid this nonsense
in the future. Notice how the bottom of page 87 says:

"You may also adjust the NMEA output to enable/disable certain sentences
and adjust the number of
Lat/Lon output precision digits. You must have one of the ports set to
NMEA In/NMEA Out to use this
option. Settings affects both Port 1 and Port 2 NMEA outputs."

This means the NMEA statements can be shut off individually in the menus.
Garmin's manual sucks explaining this, as usual, because they want you to
get your Garmin DEALER to install it to make him happy. Hold that
thought and let's go look at the Icom manual.......

http://icomamerica.com/products/marine/m422/specs.asp
"NMEA In/out formats : RMC, CGA, GNS, GLL"
These are the statements the new radio is looking for, well, the last 3
letters of the statements, anyways.....

http://icomamerica.com/support/manuals/m422_manual.pdf
On page 35, NMEA IN is the RED lead (again black is ground, damn them.)
So, we'll hook the BLUE lead from Comm 1 of the Garmin to the RED lead
NMEA IN on the Icom. While we're here and have this nice Chart Plotter
Garmin, let's hook NMEA OUT (the white lead) on the ICOM to the Comm 1
NMEA IN (the brown wire) on the Garmin cable. This SHOULD, but may not,
allow us to automatically plot any DSC distress calls the ICOM receives
on Channel 70..directly on the Garmin charts.

The Icom sends out DSC and DSE statements to the Garmin. But, on page 96
of the Garmin manual, there is no reference to DSC or DSE statements on
the list, there. However, back on page 81 you turn ON the DSC charting
function from MAIN MENU then DSC tab. Turn the DSC to ON, which should
make it read one of these DSC/DSE statements and do "something" the
damned manual doesn't really say what, which isn't new. Don't worry
about MMSI in the Garmin. You can play with that some other time. We
want it to plot ALL stations, not just one.

OK, so the Garmin Comm 1 should be now hooked to the Icom NMEA wires with
a common black wire between them (not depending on the battery wires,
please!)....

Power on the GARMIN and let it sync to the birds. While it's got you
waiting, check the NMEA output statement list and make sure statements
GPRMC, GPCGA, GPGNS and GPGLL are active, not disabled. As there is no
settable speed on these ports any more, we'll assume they are 4800 baud,
n/8/1 and auto setting. It's about time.

Ok, Garmin has a fix, turn on the ICOM with all fingers crossed. Does
the lat/long from the Garmin show up on the Icom display? No? Of course
it doesn't! This Icom HAS NO LAT/LONG DISPLAY! Look at page 4 of the
Icom manual, bubble number 7 the "GPS" indicator on the display. Is it a
solid GPS? If so, the Icom has a fix. If it's blinking, we have data
coming out of the Garmin, but none of the statements the Icom is looking
for is in the data stream to it, or there's noise/hum/buzz/crap from the
damned unbalanced wiring both these companies are using...damn them
again! That's the ONLY display of GPS information on the M422. It costs
a lot more money, M602, to get that lat/long display. Have one, what a
waste...it's a VHF RADIO. This unit's much better and easier to use. If
there is no little GPS symbol at all, there's no signal at all from the
Garmin...wiring error, shorted wires, defective equipment, etc.... It's
gotta be a steady, non-blinky GPS display.

Ok, once we gots all that workin', get the new Autopilot installed and
we'll hook it to Garmin's Comm 2! No sense leavin' perfectly good wires
just dangling there with no toys attached, right?!

Hope this helped you a little better....All this crap needs a good
Ethernet jack on it plugged into a router you can get at any Circuit City
for $60. Then, the radio would KNOW who the GPS, Chartplotter, Autopilot
and other gadgets was from their BROADCASTS and the router could easily
route like a little LAN as it should....not this wrappin wires together
crap we're buying now. How awful......

Larry, that's NMEA 2000, except it uses CAN bus rather than Ethernet.

It's starting to show up in some GPSs, but I haven't seen any DSC VHFs with it. Yet.

Yeah, I know, CANbus, another queer, off-the-wall, stupid plan from NMEA
trying to keep the boater from buying READILY AVAILABLE, reasonably-priced,
off-the-shelf, STANDARDIZED data hardware that uses STANDARDIZED
connectors.

Just look at all the wonderful CANbus boxes you can buy at Best Buy or
Circuit City or newegg.com or any computer shop! Everybody knows a lot
about CANbus....must be 20, maybe 30 people, worldwide who are not
designing CAR computers!

Wanna bet the CONTROLLER in Garmin will NOT work quite right with the
CONTROLLER in Icom or the CONTROLLER in Raymarine or the CONTROLLER in
anything else?

We'll see......too late.

Yeah, it would be great to go to best buy and get an ethernet hub for
the boat. It would rely on 120vac (but that is fixable) and it would
allow me runs up to 300', repeaters, and routing. JUST what I need on a
43' boat.

Ethernet is AWESOME when you have LOTS of hosts that you want/need to
address individually. Note how well multicast has done. If they used
ethernet for the NMEA spec, it would be a total horror show. AND all of
your devices would cost more as the manufacturers would have to do MORE
software engineering to compensate for ethernets shortcomings for this
applicaiton. Dont get me wrong, NMEA is totally bjorked, but using
ethernet would NOT have been the answer. If manufacturers want to use
ethernet for their proprietary data transfers, thats cool, but why make
my temp sensor use a heavy ethernet interface?

I for one welcome our new CAN bearing overlords and am looking forward
to their benelovent, data sharing rule.
