Fuse and Power LED
The +5-V line from the data acquisition board is protected by a 750-mA fuse. If the red power
LED does not light when the data acquisition board is powered on, check both the 750-mA fuse on
the BNC-2080 board and the output fuse (if any) on the MIO-16 board. Information on
connecting power is given in Chapter 4,
Installation and Connections
.
Digital and Timing Signals
All of the analog signals and a few digital signals from the MIO-16 data acquisition board are made
available at BNC connectors on the BNC-2080 board. Because these signals are not conditioned
or changed in any way by the BNC-2080 board, refer to your MIO-16 board user manual for
information on the use of these signals. If you want optical isolation of or relay control by the
digital I/O lines, you must use the SC-2050 cable adapter board and the appropriate SC-2060
digital signal conditioning board. If you want access to all MIO-16 signals via screw terminals,
you must use the SC-2070 or SC-2072 board. For more information on the SC-205X Series
boards, the SC-206X Series boards, or the SC-207X Series boards, refer to either your National
Instruments catalog, the
SC-205X Series User Manual
, the
SC-206X Series User Manual
, or the
SC-207X Series User Manual
