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.

Operation Mode
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.
