About

This

Manual

This manual describes the mechanical and electrical aspects of the

PC-LPM-16PnP and contains information concerning its installation,

operation, and programming. The PC-LPM-16PnP is a low-cost, low-

power analog input, digital, and timing I/O board for the IBM PC/XT,

PC AT, Personal System/2 Models 25 and 30, and laptop compatible

computers.

This manual also applies to the PC-LPM-16, a non-Plug and Play board.

The boards are identical in functionality, programming, and

performance, except for the differences listed in Appendix C,

Using

Your PC-LPM-16 (Non-PnP) Board

.
