3.连接工业相机：

1.配套的USB3.0数据线一端连接计算机蓝色USB3.0接口，另外带螺丝紧固的一端连接USB3.0工业相

机

4.安装软件：

1.安装USB3.0Host controller/USB3.0可扩展主机控制器驱动，Windows的控制面板>系统>设备管理>通

用串行总线控制器中查看

2.安装NI Vision Acquisition Software August2013以上版本软件

5.确认相机在设备管理器中：

1.打开Windows的控制面板>系统>设备管理

2.确认相机已安装在NI Vision Acquisition Devices列表下

3.如果相机显示在其他设备列表下，则需要手动安装相机驱动，步骤如下：

1)右键点击相机选择更新驱动程序软件

2)选择浏览计算机以查找驱动程序软件

3)选择从计算机的设备驱动程序列表中选取

驱动文件路径

64位操作系统C:\Program Files(x86)\National Instruments\NI-IMAQdx\Staging\NI USB3Vision 32位操作系统C:\Program Files\National Instruments\NI-IMAQdx\Staging\NI USB3Vision

选择niu3vk.inf文件打开后，点击确认

显示兼容硬件，选择NI-IMAQdx USB3Vision Device，点击下一步

驱动安装成功后，提示Windows已经成功地更新驱动程序文件，关闭即可。

6.在Measurement and Automation Explorer(NI-MAX)中测试相机:

1.运行MAX，开始>National Instruments>Measurement and Automation Explorer

2.相机将显示在我的系统>设备和接口（>NI-IMAQdx Devices）列表下

3.点击Grab或Snap测试图像采集

7.故障排除

The Camera does not appear in Measurement&Automation Explorer(MAX)

Case1:The camera is not USB3Vision compliant

The camera must comply with the AIA USB3Vision Specification version1.0or later.All USB3Vision cameras should

display the compliance logo on the camera or in marketing literature.

Note that even though the marketing literature for a USB camera may indicate that it is USB3Vision compliant,it is possible

that the firmware on the camera is outdated and must be updated in order to achieve full USB3Vision compliance as

indicated in the literature.Contact the camera manufacturer to verify if the camera is USB3Vision compliant and to

request a firmware update that is compatible with USB3Vision.

Case2:The NI-IMAQdx driver is not installed

The NI-IMAQdx driver must be installed for a USB3Vision camera to be used with National Instruments software.

1.In the MAX Configuration window,select My System»Software.

2.Expand Software,and verify that NI-IMAQdx appears in the list.If it is not listed,then NI-IMAQdx must be

installed.

3.The latest version of Vision Acquisition Software,which includes NI-IMAQdx,can be downloaded from the Drivers

and Updates page.

Note:NI-IMAQdx is not available for free.You can use it as a full featured evaluation version for30days after which you will need to activate for further use.

Case3:The USB host controller is not compatible with the USB3.0specification

Make sure that your USB host controller is compatible with the USB3.0,also known as SuperSpeed USB.You may also wish to check the USB Implementers Forum(USB-IF)website,which provides a list of hardware that is compliant with USB 3.0.

Case4:The USB cable length is too long

The maximum length cable length for USB3.0devices is not explicitly specified in the USB3.0standard.However,the standard provides a description of the relationship between wire gauge and maximum length in order to prevent too high a voltage drop and attenuation.Thus,for passive cabling solutions,a length of5meters or less is recommended.

Case5:Inadequate Power is being provided to the camera

Power can be provided to the camera directly over the USB3.0bus.According to the USB3.0specification,the maximum power that can be supplied is4.5watts at5volts.If there are other devices that require large amounts of power,it is possible that there is insufficient power being supplied to the camera.In this case,you may wish to investigate the use of a powered USB3.0hub.

The Camera cannot acquire images at the advertised frame rate

USB3.0allows a maximum throughput of400MB/s.However,every component from the camera,cable,USB3.0ports to the PC and its drivers could limit the effective throughput.Bus speed and/or the USB host controller interface are two factors that may have an effect on frame rate.

Case1:PCI interface for USB3.0Host controller cannot handle the bandwidth requirements

To ensure that the camera can send data at the rated speed,please ensure that your USB3.0host controller interface and your motherboard support PCIe2.0data throughput rates,which is effectively384MB/s.PCIe1.0architecture cannot exceed180MB/s,while regular PCI supports only133MB/s.

Case2:Host controller interface does not support USB3.0

Make sure that your host controller interface and/or your motherboard support version3.0of the USB standard rather than version2.0.It is possible that the USB3.0camera is running on USB2.0bus,but at just480Mb/s,the throughput of USB 2.0is significantly less than USB3.0.
