External Power Connection (If Necessary)
Your BNC-208X Series board draws very little current from the computer power supply. If several
high-current SC-206X Series digital signal conditioning boards, such as the SC-2062 board, are being
used on the same data acquisition board as the BNC-208X Series board, some of these boards need to be
powered by an ex5-VDC supply. Because the SC-206X Series boards draw much more current
than the SC-207X Series or the BNC-208X Series, the SC-206X Series boards should be powered from
the external supply, and the SC-207X Series board or the BNC-208X Series board can be run from the
host computer power supply. If an external power supply is needed for the SC-206X or SC-207X
Series boards, see the
External Power Connection
section of the
SC-206X Series User Manual
and the
SC-207X Series User Manual
