Chapter 1

Introducing the PC-CARD-DAS16/16AO

Overview: PC-CARD-DAS16/16AO features

The PC-CARD-DAS16/16AO is a data acquisition and control board for IBM PC compatible computers with PCMCIA type II slots. The PC-CARD-DAS16/16AO provides 16 single-ended or 8 differential analog inputs, 16-bit A/D resolution, two analog outputs, four digital I/O lines, and three 16-bit down counters.

The analog input range is fully programmable in one of four bipolar ranges. An on-board pacer clock, or an external pacer input, or software polling can trigger A/D conversions. Transfers are via software polling, interrupt service or REP-INSW. A 4096-word FIFO buffer provides buffering between the A/D circuit and the PCMCIA bus.

The PC-CARD-DAS16/16AO provides two single-ended 16-bit analog voltage outputs. The analog output range is ±10 V.

The four digital I/O bits are available on one 4-bit port. The digital channels are software configurable as four inputs or four outputs, and allow you to sense and control discrete events.

All signals pass through a 50-pin high-density connector. The board is completely plug-and-play, with no switches or jumpers to set.
