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 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.

The execution mode of the board is the USB boot mode and flash boot mode. The Flash
boot mode (jumper OFF) is the general board operation. On the other hand, the USB boot
mode is used when frequent firmware updates or develops flash memory program.
3.2 USB-B Connector (CN1)
It is a B-type USB connector. It is connected to a PC and is done a data transmission.
3.3 LED(PWR, RUN) (D22)
The power and status of board is displayed. When connecting the power, the red led
light on. When collecting the data, the green led light on.
