3.1 Hardware Set-Up
The hardware must be properly configured prior to use. Follow the instructions below to set up the EVB:
1. Connect the communication interface to the computer
’s USB port with a USB isolator.
2. After the communication interface is recognized by the computer (see Figure 7), locate the proper
wires to connect the EVB to the EVHR1203 PMBUS Kit-01A communication interface.
3. Connect VCC, VREG, BURST, SCL, SDA, and GND (see Figure 8). If needed, refer to the datasheet
for further clarification.
