FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the USB-6509 always require this external supply?

No. NI describes the USB-6509 as bus-powered and states that an external supply is not required for outputs.

How should external power be connected to the USB-6509?

The user guide instructs users to disconnect the USB cable, remove the DC-jack cap, and connect the +12 VDC supply. Do not remove external power while the device is powered on; NI warns this can reboot or damage the device.
