eze System Notes - In this space we provide: wiring instructions, product image, product details.

Sensitivity - Use the drop-down menu to select the acceptable level of accuracy. Precise location only, Normal precision or Accept low signal. If horizontal accuracy falls below the selected level of precision the driver status will indicate an “App error”.

Timeout - Use the drop-down menu to select how long after the last time of fix (30s, 1min, 2min, or 10min) before indicting an “App error”.

Driver info - Typically this is the name from the program file

1. Time of last fix - Gives the time of the last location calculation. Time of last fix should be within seconds of current UTC time.
2. Satellites in use - The number of satellites currently in view / utilized by the receiver.
3. Latitude - North-South coordinate
4. Longitude - East-West coordinate
5. Elevation - Approximate height relative to sea level, given in meters
6. Horizontal accuracy - Expressed as dilution of precision (DOP). In this metric readings of less than 1 are ideal and greater than 20 are poor.
7. Speed - Speed of travel is given as meters per second.
8. Course - Current direction of travel is given as degrees. Tip: Use “Display format in view” option “Degrees as direction” to display as compass direction. Example: 245 = Southwest
