The USB connector (see Figure 3) is used for charging the battery and for data 
communication.  The unit will charge from a laptop computer, AC to USB power 
adapter, or vehicle power to USB adapter.  (See Figure 3) 
 
Data communications with the Mini-MT is also performed through the USB connector.  
The USB connection is used to configure or customize the Mini-MT operation.  This 
connection also is used to provide GPS NMEA data to a mapping or user application.
