Accessories

Accessory Power

The PXIe-4310 provides auxiliary power for accessories connected to the module and has
protection in the event of a fault condition. If a fault occurs in the form of an over-power
condition, the power supply latches off until it is reset. To reset after a fault condition perform a
Device Reset in MAX or programmatically in your Application Development Environment
(ADE).
