Please check that for updates, announcements etc. http://www.wsrcc.com/wolfgang/gps/dgps-ip.html You can get the WinDGPS from: http://www.wsrcc.com/wolfgang/ftp/ Grab the highest numbered WinDGPSxx.zip file. Unzip with your unzip utility. This will create a file WinDGPS.exe. This is your executable. Under win95 you should see this file appear as an icon with a blue globe in a half gray, half white box with the label "WinDGPS" underneath it. To run, double click on the WinDGPS icon. This will pop up the main WinDGPS window. The first time you run the program you'll have to choose the com port that the GPS data-cable will be plugged into and the baud rate that the GPS is set to. If you have a Garmin GPS use the "PAGE" button to cycle to the menu page. Use the down arrow key to highlight "INTERFACE", and press the enter key. Now use the down-arrow key to highlight the protocol. Press enter. Now use the down-arrow key to scroll through the choices. Depending on your GPS model number and type one of the choices is either "RTCM/NMEA" or "NMEA/RTCM". The G12 and G12xl will have the former choice. The G-II/G-III's will have the latter. Press enter again when the above RTCM protocol appears. If your GPS lets you chose the baud rate, you may do so now. The Garmin default is 4800 baud. The WinDGPS default is 9600 baud. Either one will work, just make sure they are the same. Now page back to the satellite view page on the GPS and hit the connect button on WinDGPS. You should see the DGPS data scrolling across the one-line window at the bottom of the WinDGPS window. If you don't see the DGPS data scrolling by, something is wrong. If you have a telnet program you can try to telnet to "host dgps.wsrcc.com port 2101". If this doesn't work, and you are trying to connect to the internet from behind a corporate firewall, then your firewall is most likely blocking the connection. You'll have to arrange with your network admin to unblock port 2101. If you see the dgps data scroll by, then the computer is getting the DGPS data delivered to it. Now check the satellite page on the gps. On the Garmins 12's the top left will have a notation that should normally say "3D-NAV". When the GPS goes into differential mode this will change to "3D-DIFF". On the G12 series the bars will also hollow out for the satellites that don't have any differential correction data available. Unless you are really far away from the reference station, almost all of the satellites bars should stay black. On Garmin GPS's the "INTERFACE" page will also have some Beacon station information displayed. If all is running well, you should immediately see the beacon's baudrate and frequency appear. If the gps has recent software, there should also be a beacon distance field. This will initially be blank, but after 15 minutes or so a beacon distance should also appear. Thats it. Enjoy!
