Warning:
Do not connect the BNC-2081 board to any board other than a National Instruments Lab
data acquisition board, the SC-2053 cable adapter board, or the SC-2071 board. The BNC-
2081 board is not compatible with any other data acquisition boards or cable adapter
boards. Attempts to use the BNC-2081 board with products for which it was not intended
can result in damage to the BNC-2081 board, the data acquisition board, or the host
computer. National Instruments is
not
liable for damages resulting from these connections.
The BNC-2081 board uses a 50-pin ribbon-cable connector to connect to the 50-pin I/O connector on
either a Lab data acquisition board, an SC-2053 cable adapter board, or the SC-2071. If the BNC-2081
board is to be used with the SC-2053 or the SC-2071 boards and is mounted in a rack, the cable should
run underneath the BNC-2081 board for easier access to the BNC-2081. For more information, see
