4.1 EVM Operation

4.1.1 Evaluation Setup
Connect the EVM as shown in
1. Physically connect P2 of the PHI to J8 of the ADS1282EVM. Install the included screws to provide a robust
connection.
2. Connect the USB connector on the PHI to the computer.
a. LED D5 on the PHI lights up, indicating that the PHI is powered up.
b. LEDs D1 and D2 on the PHI start blinking to indicate that the PHI is booted up and communicating with
the PC; Figure 4-1
3. Start the software GUI as shown in
is loaded on the PHI. This loading takes a few seconds. LED D1 on the ADS1282EVM illuminates once a
connection has been established.
4. Connect the differential signal generator to the ADS1282EVM inputs. The full-scale input range is ±2.5V
differential with a common mode from 0V to 2.5V. A typical input signal is a 4.8V
signal is adjusted just below the full-scale range to avoid clipping.
5. Verify the default jumper positions of the ADS1282EVM. Jumper JP1 is placed in the UNIPOLAR position
(pins 1-2) by default. Jumper JP3 is placed in the ENABLE position (pins 2-3) by default.
