Re: GPS Enabled

Burt N Sammis

Sorry I have not gotten back to the group.  I have had other priorities that got in the way.
Robert I appreciate your suggestion on going into the RFport, etc. I am not computer literate to do that.
 I am listing the various settings on APSISIECW 32 and D710 settings
     checked   APRS-IS           enabled
     checked   Beaconing      enabled  
     checked   GPS                 enabled
     checked   Internet acc   enabled
     checked   OMS Fetch              enabled

Menu View Logs
     Port NMEA
          Error opening ComPort 3


     Menu 602
          Baud rate - 4800 bps
          Input     GPS
          Output  Waypoint

Maybe the above can help clear this up.
Otherwise, I will go with what I have.  My problem if it available I want it to work.

Just to be certain:
in the APRSIS32.xml file RFPort looks something like:
<RFPort Name="D710">
      {snip - other settings not being discussed}
      {          although <OpenCmd> commands could be VERY important!  }
     {snip - other settings not being discussed}
and the section about NMEA ports looks like this:
Remember, APRSIS32 must be closed when hand editing the xml.

As Robert outlined below, you should NOT configure nor enable an NMEA/GPS port for passthrough.  Windows only allows each COMM port to be opened once, and the RF Port is doing that.

Please de-configure your NMEA port and make sure the GPS/NMEA checkbox is checked on your RF Port.  And then you'll also need to ensure that the RF Port's <OpenCmd>s specifically enable GPS sentences to be sent from your radio.

I eliminated the radio.  I changed the radio (D710G) to a D710 with an external GPS (Green Leaf Labs)  Has always worked great in any situation.  And, still does.
GPS is flashing in the upper right corner of the D710.  The radio now becomes a pass thru to APRSISCE.
Still the same result.  The computer indicates the problem is connecting to Com 3.
Com 3 is the USB virtual port for the D710 also.

I believe NMEA is open means the state is trying to open the NMEA port.

Is COM3 the USB virtual port for the D710G?
  Or a different port - remember the 2 sets of data are on the same port.

Close APRSIS32 and find the APRSIS32.xml file (in the APRSIS32.exe folder).
   Open it in a text edit and search on GPS.
You should find:
 and later in the file
If the second instance has anything in it (like <GPSPort>vom3:9600,n,8,1</GPSPort>)
   delete everything between <GPSPort> and </GPSPort>

Then go down and find your <!--RFPort[#]--> port settings
If you have more than one, find the one for the D710G and check these settings:
   <Device> {your settings} </Device>

{Your settings} will tell you what APRSIS32 uses for a COM port and the settings.  Is that COM3?

GPS/NMEA are checked.
On the APRSIS display screen upper left corner "APRS is OK."
     "NMEA is open"
Enables menu-View all logs, NMEA log shows an error message: "Error opening Com 3"  It tries to connect but cannot.
Something is hindering the opening Com 3.

Robert, remember our email of July 24 when I "fixed" menu 500 and said that was it.
I had a power outage after that and everything went to hell.

I thought you were using a GPS connected to the radio and feeding NMEA messages through the configured RF port?
    GPS/NMEA checked.
If the D710G is sending GPS data, it is on the RF port.

Do not try and configure a different port  with >Configure >Ports > NMEA.
Double check to see that iGPS is showing on the D710G display and if not, menu 500.

As I recall (Lynn can verify), the GPS data comes through as plain text.
To view it in a terminal program you would need to:
   1. Close APRSIS32 RF port from D710G (same comm port as GPS data is on
   2. Open terminal program (ComTestSerial, TeraTerm, or RealTerm  are all good free options)
   3. Set port parameters to match the D710 port settings
Yuo will see some "KISS" code, but you shoulod also see GPS messages from the radio.

What version of Windows are you on?  Can you connect to the GPS Comm port with a terminal emulator like putty or teraterm?

OK Robert, I blew it.
I am unable to receive GPS info on APRSISCE.
I click on CONFIGURE then Ports, then NMEA which gives me the following.
"RegOpenKeyEX." In the same box is: "Failed to OpenSERIALCOMM Key"
What happened?

Thank you Robert!!!.
Menu 500 was the key. GPS output has to be ON. That did it
I have been trying to get the GPS function to work for months.
Again, thanks.

I don't have either, but a friend has the "nonG" model.

Glacing through the manual for the G model, I see there are different indicators, depending on which GPS is in use:
    iGPS     => internal
    GPS     => external connected tothe 2.5 mm jack.
Menu 500 still offers GPS OUTPUT (GPS data output to PC)    Default OFF
Menu 501 SENTENCES with the most common 4 as default
Then moving up to Menu 6xx
   602 has key setting
   603 more settings
   604 Another ON/OFF toggle, but for APRS.
          I wonder if you have need to turn this OFF to allow raw GPS to the PC.
          Some systems allow APRS as WAYPOINTS only and won't send raw GPS strings when requesting APRS output.
          I can't say fro this Kenwood.

I didn't see anything that indicated you couldn't output the internal GPS data

Burt indicates that he is using a "G" model 710 with the *internal* GPS.

The reason I point this out is that I have a 710 and was considering upgrading to the 710G at one point, but I thought I read somewhere that with the "G" model you cannot have the internal GPS data pass through to the serial port, and that pass through only works for an externally connected GPS unit on the "G" model.

Can anyone confirm whether this is true or not?
