Getting Started
1.2
Quick Start Board Setup
The DRV2700EVM-HV500 comes with preprogrammed firmware to provide a 0- to 500-Vp signal between
the output and GND.
1. Out of the box, the jumpers are set to begin demo mode using USB power. The default jumper settings
are found in
Table 2
.
2. Connect a mini-USB cable to the USB connector on the DRV2700EVM-HV500 board.
3. Connect the other end of the USB cable to an available USB port on a computer, USB charger, or USB
battery pack.
4. If the board is powered correctly, the 5-V LED is on.
5. Enable the output using the GUI or programmatically through the computer, see
GUI Interface
for
additional assistance. If using an external input signal, EN the output by changing the jumper (JP3) or
equivalent control signal.
6. Once the output is EN, the device allows for the high-voltage output.

Connecting a Load
1. With the power supply off, connect the negative terminal of the load to GND and connect the positive
terminal of the load to the "HIGH VOLTAGE" side of JP2.
2. Ensure the terminals are connected correctly, then enable the supply
CAUTION
Before connecting the load, ensure that the load is rated for the selected output
voltage. If not, see the
Programming the HV Maximum Output Voltage
section
to adjust the DRV2700 maximum output voltage.
