1. Introduction

NET-AIO11 is the High function Signal Processing board to support Analog Input and

Digital Output. The 8-channel A / D converted data by applying TI TMS320C55xx DSP

chip analog signal can be obtained the high speed data via USB 2.0 interface and Ethernet

interface.

The device can be used to support the power over Ethernet cable(UTP). There are no

separate power devices because the power is supported through the Injector or

PoE(Power over Ethernet) Hub.

1.3.1

Continuous Mode

Continuous Mode, is that continuously collect the data from board. Setting the

Sampling Rate by selected Interface (USB/NET) is collecting the data continuously.

1.3.2

Delay Mode

Delay Mode, via set the Sampling Rate after a certain time, is that total 524,288(512k)

data store in the memory, and read the data when the user want.
