Test Procedure:
Initial Test Set Up
PI5101-EVAL1 is configured for a 3.3V redundant bus
application. Under-Voltage (UV) and Over-Voltage
(OV)
voltage divider resistors are selected
appropriately for 3.3V nominal bus voltage. Refer to
section 2 on page 6 to calculate OV and UV resistor
values if another input voltage is desired. Both PI2001
controllers are configured as Master.
