Temperature Disable: Connecting a 10Kresistor be-
tween THERM and SNS disables temperature control.
VSEL (JP2): Selects -V or peak-voltage detection, or
disables voltage-based termination (see bq2004 data
sheet, page 7).

bq2014 VCC Supply (JP5, JP13). These jumpers are
used to enable the onboard voltage regulator to the
bq2014 from the battery pack. If the battery pack con-
sists of 3 or 4 series cells the gas gauge can be powered
directly from the battery with no regulation. For a
greater number of cells, the regulator should be enabled.

Programming Pins (JP6–JP10). These jumpers are
used to configure the gas gauge for battery capacity and
self discharge rate. See the bq2014 data sheet for
proper configuration. The board is shipped with all pins
in the high impedance state.
LED Enable (JP11). JP11 enables the gas gauge
LEDs. The board is shipped with the LEDs enabled.

3. Enable/disable the voltage regulator with JP5,
JP13.
4. Connect the provided thermistor between THERM
and PACK-. A 10K resistor across THERM and
PACK- disables temperature termination.
5. Connect the RS232 cable from the EV2014x board
to the serial port of a standard PC. Please ensure
that no memory resident programs use this port..
6. Connect the load across BAT+ and PACK-. A sense
resistor RSNS2 is in series with the negative termi-
nal of the battery. The EV2014x board is supplied
with a 0.100ohm, 1% 3W resistor. Please ensure
that the discharge load does not exceed the Vsr
specification for the bq2014. RSNS2 may be
changed to a different resistor value..
7. Connect the battery to BAT+ and BAT-. Impor-
tant: Connect the battery ONLY after setting
JP6–JP10 and JP5, JP13.
8. Attach the power supply to the DCIN and DC RTN
connections in J2.
Installing the User Interface
Program
The User Interface Program (named “EV2014x”) runs on
any PC-compatible computer. The program may be run
from the disk provided, or it may be installed on any di-
rectory on the computer's hard disk. To run the pro-
gram from the hard disk, simply copy all the files from
the disk supplied to the hard disk. All the files should
reside in the same directory.
The User Interface Program installs a driver to control
the DQ/RS-232 interface. This driver asks which COM
port is connected to the EV2014x Evaluation board. If
communication is not established with the EV2014x
board, the Main Menu does not appear. Please refer to
