1.1 Introduction

The PCM-3718H/3718HG is a high performance multifunction data

acquisition module that attaches to the PC/104 connector on your

CPU card or PC/104 module. It offers 12-bit A/D conversion and

digital input/output.

The automatic channel scanning circuitry and the on-board SRAM let

you perform multiple-channel A/D conversion with DMA and

individual channel gains.

The PCM-3718H/3718HG is an advanced new version of our popular

PCL-818 multifunction data acquisition card series. A custom 160-

pinASIC chip integrates the functions of a full-size DAS card. This

chip gives you maximum accuracy and reliability, along with

minimum cost, size and power consumption.

The resulting PC/104 module is fully software compatible with the

PCL-818H/818HG. This puts rich software support and a wide variety

of external signal conditioning boards at your disposal.

The PCM-3718H/3718HG is excellent for data acquisition, process

control, automatic testing and factory automation.

1.2 Features
