1.1 Introduction

The PCM-3718 Series consist of high performance multifunction data
acquisition modules that attach 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 onboard SRAM let you
perform multiple channel A/D conversions with DMA and individual
channel gains.
These PC/104 modules are fully software compatible with the popular
