When finished, turn off any powered external signals to the BNC-208X Series board before turning
off the computer.
Warning:
The BNC-208X Series boards have not been designed for use with high voltage. Although
the open component positions are configured so that voltage dividers can be installed to
reduce a high input voltage to within the
±
10-V data acquisition board input range, the
maximum safe input voltage at any point on the BNC-208X Series boards is 42-V peak.
Input voltages larger than 42 V, even if attenuated by a voltage divider on the BNC-208X
Series board, can result in damage to the BNC-208X Series board, the data acquisition
boards, or the host computer. High voltage can also cause an electric shock hazard to you.
National Instruments is
not
liable for damages or injuries resulting from these connections.
Installing the SC-205X Series Cable Adapter Boards
Consult the
SC-205X Series User Manual
for instructions on the installation of your SC-205X Series
board if any of these boards are being used.

Consult the
SC-207X Series User Manual
for instructions on the installation of your SC-207X Series
board if any of these boards are being used.
Rack Mounting
Your BNC-208X Series board can be installed on half of a 19-in. rack-mount chassis. You can mount
one BNC-208X Series board alongside an SC-205X Series cable adapter board, an SC-206X Series
digital signal conditioning board, or an SC-207X Series general-purpose termination breadboard. You
can mount your BNC-208X Series board on the left or right side of the 19-in. rack mount. Mounting the
BNC-208X Series board on the left side of the rack and any other of the SC Series boards on the right
side of the rack will make access to both boards easier. Run the connecting 50-position cable underneath
the BNC-208X Series board to the adjoining board. The BNC-208X Series board occupies half of a
19-in. rack, as shown in Figure 4-1 and Figure 4-2.
