- is there any delay in the on/off switch between the tracking on the monitor and the pressing of the button?
Basically it is being processed with the next GPS signal as "OFF". So on a 1 Hz model, this would be 1 s in the worst case. With a 5 Hz model the worst case would be 200 ms. You can use the F2 key to turn equipment ON and OFF. I also offer an interface box (I can supply the schematic for free) which allows you to integrate into any 12V signal indicating ON or OFF. This could be a relay, an elec. clutch on your drill, or simply your master ON/OFF switch assuming its using 12V (most do). I even allow the integration to individual sprayer sections...
- what kind of format do you support to upload the map?
The default is a simple text format. I decided to use text as you can basically transform into any format with some programming skills. I also allow export to KML (Google Earth) or shapefile shp files formats.
- I plan to use a tablet which has already a GPS integrated. Would this be also possible?
Yes as long as the GPS receiver provides NMEA out.
- I saw that you can toggle the color by pressing Q,W or E. I guess I can use this to switch it on and off. can I configure the color and width for each character?
You can do what you are asking for, but the keys Q,W,E and R are used for color changes only. This is meant to indicate "special" areas in your field. An example would be that you do your own field trials and decide to increase fertilizer for 2 passes. I would press Q (or W or E or R) to mark these 2 passes.
You can setup as many equipment pieces as you like. All can have their own configurations (width, offset to antenna, etc.) and can be selected in the main screen. Go to Options/Setup/Equipment and explore. Since you are in Germany, you may choose German in the Setup... hope I did not miss to many translations. Please let me know if I did miss anything...
Consider the time change (you are 8h ahead of me), but give me a call if you have questions. From Germany dial: 001 780 990 4052 for my handy.
