Page 4: Important Safe Handling Information
The list here describes common causes of failure found on boards returned to Diamond Systems for repair. This information is provided as a source of advice to help you prevent damaging your Diamond Systems (or any vendor’s) embedded computer boards. - Page 5 Overvoltage on analog input – If a voltage applied to an analog input exceeds the design specification of the board, the input multiplexor and/or parts behind it can be damaged. Most of our boards will withstand an erroneous connection of up to 35V on the analog inputs, even when the board is powered off, but not all boards, and not in all conditions.
