ADM-VPX3-9V2 User Manual
3.8 System Monitor
The ADM-VPX3-9V2 has the ability to monitor its own temperature, voltages, and currents of certain power
supply rails. These metrics provide an indication of board health. The monitoring is implemented using an Atmel
AVR microcontroller.
If the core FPGA temperature exceeds 105 degrees Celsius, the FPGA will be cleared to prevent damage to the
card.
The microcontroller monitors can be read out via USB using the avr2util utility, and also via PCIe using the Alpha
Data Board Support Package (BSP).
