ADM-PCIE-9V5 User Manual
3.6 System Monitor
The ADM-PCIE-9V5 has the ability to monitor its own temperature and the voltages and currents of certain power
supply rails, in order to 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 power supply rail voltages & currents and temperatures at certain points on the
board. This information can be read out via USB using the avr2util utility, and also via PCIe if RD-9V5 is
purchased.
