Measurement Computing PCM-DAS16x/16 - Manual (Page 5)

1 INTRODUCTION
The PCM-DAS16x/16 is a data acquisition and control board for IBM PC compatible
computers with PCMCIA type 2 slots. The heart of the board is an analog to digital
converter. Analog signals are routed to the A/D via either an 8:1 differential multi-
plexor PCM-DAS16D/16 or a 16:1 single ended multiplexor PCM-DAS16S/16 con-
trolled by a register on the PCM-DAS16x/16. The analog input range is fully pro-
grammable in several bipolar ranges. An on board pacer clock and external pacer
input as well as software polling may trigger A/D conversions. Transfers may be via
software polling, interrupt service or REP-INSW. A FIFO buffer provides buffering
between the A/D circuit and the PCMCIA bus. Eight digital I/O lines (8 in or out , or,
4 in 4 out) provide a means of sensing and controlling discrete events.
