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.
