ADM-PA101 User Manual
3.7 System Monitor
The ADM-PA101 has the ability to monitor select temperatures, voltages, and currents in order to provide an
indication of board health. The monitoring is implemented using an AVR microcontroller. This information can be
read out via USB using the avr2util utility. Alternatively, the sensor information can be read directly by the ACAP
or via PCIe if RD-PA101 is purchased (reference design package).
If the core ACAP temperature exceeds 105 degrees Celsius, the ACAP image will be cleared to prevent damage
to the card.
