This connection is not useful when using a system load, charger, or
a power source (battery or external power supply). The red wire of
the EV2300 connector gives access to a low-power, 3.3-V output
when connected to HDQ section of EV2300. Shield this wire when
it is not in use to avoid contacts with other connections such as
ground.
Run the program from the Start|Programs|Texas Instruments|bq27X10 Battery Gas Gauge menu
sequence. The software defaults to the PC USB port for communication. If the EV2300 is connected to
USB port, the program should load and display the initial data screen. If it is the first time that the program
is used, then the user is prompted to select between the bq27010 or bq27210. Select the appropriate
device, and then press the continue button.
