You have to enter your coordinates into the latitude and longitude, don't worry about the offset, we will do that on the next screen. If you select the different locations, you can see the sign change on the display. Notice that the Longitude is Negative in the USA and Positive in Europe

Below at the bottom is a table showing the different formats for expressing Lat and Long.  Use entry two format for the hand controller.

Touch in the Longitude box. When you do the Longitude entry screen will appear.
Do what is indicated in that screen. After that you will be brought back to this screen.

Touch in the Latitude box, You will be taken to a screen similar to the one you just filled out. After filling out that screen you will be brought back here again.

Longitude is entered as 180 to -180 degrees: 0 to 59 minutes: and 0 to 59 seconds. Seconds is optional and not shown.

Latitude is entered as -90 to +90 degrees: 0 to 59 minutes: and 0 to 59 seconds.
Seconds is optional and not shown.

Hit the Back button.  

Note: the Hemisphere is selected totally by the sign of the Latitude in the Gemini-2. Positive for Northern Hemisphere and
negative for Southern Hemisphere. It was the same in the Gemini-1 also. No switches to change at all.

The Query GPS button will have the Gemini-2 try and get the GPS coordinates from a GPS unit hooked to Serial Port 1
The speed of this ports defaults to 4800 baud for GPS use. It's speed is set in the Web interface under Serial Tab.

Note: If you are using a GPS receiver to get the time, then the offset does not matter. The Gemini-2 only uses UTC time for all it's calculations, and a GPS returns UTC time only.  You can disregard the time screen when using a GPS receiver.
