C
This appendix describes the differences between the PC-LPM-16PnP
and the PC-LPM-16 non-PnP boards, the PC-LPM-16 board
configuration, and installing the PC-LPM-16 into your computer.
Differences between the PC-LPM-16PnP and
the PC-LPM-16
The PC-LPM-16PnP is a Plug and Play upgrade from a legacy board,
the PC-LPM-16. A National Instruments
legacy
product refers to an
older board with switches and jumpers used to set the addresses. The
original board has been replaced with a backwards-compatible, revised
PC-LPM-16. This revised board has the same functionality as the Plug
and Play version (except for the base address and interrupt selection),
but differs somewhat from the legacy board. The following list
compares the specifications and functionality of the newer boards with
the obsolete board.
