Figure 6-2 Ferrite Core

The ferrite cores may be removed from the DAQ unit; however, in order to conform to CE standards, all of the ferrite cores must be attached to the USB cable and power adapter.

NOTE:

If the user is not using the power adapter but relying on power from the host USB connection, no ferrites are required.
