产品介绍

USB信号延长器可以突破电脑主机对USB线的长度限制，用户可以使用本产品通过单根网线远距离使用USB口，采用RJ45将任何Usb2.0设备连接并进行数据传送,可以达到高150FT的远距离数据传送，无须另外电源供电,采用IC芯片，性能更加稳定，产品可以广泛应用于计算机领域和教育等（如数码相机，打印机,鼠标，蓝牙等一些小功率USB设备），不用放在电脑旁，支持再次扩展。

产品特点
１、采用国际新USB传输技术，更具有稳定性，对工业环境更具适应性
２、支持USB1.1\ USB2.0\USB3.0接口，几乎兼容所有USB设备
３、将电脑USB接口按实际需求延长至50米，低速设备最远达100米
４、使用单根网线，无需外界电源，使用安装方便
５、无需驱动程序，容易操作
６、可以热插拔USB设备
７、能耗小，发热低，不需要额外电源
８、设备小巧，安装方便

应用范围
1、配合VGA音频双绞线传输器达到将控制端与USB外围延伸。
2、USB工业控制设备延伸，让工作人员在远程操作监控计算机。
3、在会议室使用USB键盘与鼠标控制远程计算机来做投影简报。
4、延伸USB视像摄影/射像机为低成本的高清视频闭路监控方案。
5、应用于网吧休闲场所，将即时聊天USB射像头长距离延长。
6、计算机集中管理，将屏幕键盘鼠标透过USB信号将计算机周边延伸。
注意事项：请使用八芯网线接线方式顺接（与家用RJ45网线接法一样），请勿用交叉接线。八芯网线其中4根线芯接地（GND）、两根接5V、两根是D+D-，不支持增网卡，无线网卡，原理是放大信号 不能放大供电。

特别说明：此产品的接口是1.1的速度，如果是买去作为观看影视的用的是2.0的设备速度会变慢，（比如接摄像头图像分辨率会下降）请购买时仔细阅读看清楚说明。

本产品是USB供电，USB只提供5V\5OOMA电流，在超长距离传输时外接设备需要有自足供电才可以达到30-50M。如您是用于接卡王，可能是由于供电问题，会不稳定，请购买时仔细阅读看清楚说明慎重选择。

[Product Introduction]
USB signal lengthener can break through the length limit of USB cable of computer host. Users can use this product to connect any Usb 2.0 device with RJ45 and transmit data over a long distance through a single network cable. It can achieve a maximum of 150FT long-distance data transmission without additional power supply. With IC chip, the performance is more stable. The product can be widely used in computer collar. Domain and education (such as digital cameras, printers, mice, Bluetooth and some other low-power USB devices) do not need to be placed next to the computer to support re-expansion.
[Product characteristics]
1. Adopting the latest international USB transmission technology, it is more stable and more adaptable to the industrial environment.
2. Support USB1.1 USB2.0 USB3.0 interface, almost compatible with all USB devices
3. Extend the computer USB interface to 50 meters according to the actual demand, and the low-speed equipment can reach up to 100 meters at most.
4. Use single wire, no external power supply, easy to use and install.
5. No driver, easy to operate
6. Hot pluggable USB devices
7. Low energy consumption, low heating, no need for additional power supply
8. The equipment is compact and easy to install.
[Scope of application]
1. With VGA audio twisted-pair transmission, the control terminal and USB peripheral can be extended.
2. USB industrial control equipment is extended to allow staff to operate remote monitoring computers.
3. Use USB keyboard and mouse to control remote computer to make projection briefing in conference room.
4. Extending USB video camera/projector is a low-cost closed-circuit video surveillance scheme.
5. Apply to Internet cafes and leisure places, extend the USB image head of instant chat for a long distance.
6. Computer centralized management, the screen keyboard and mouse through the USB signal will be extended around the computer.
Attention: Please use eight-core network connection method (same as home RJ45 network connection method), do not use cross connection. Four of the eight-core network lines are grounded (GND), two are connected to 5V and two are D+D-. They do not support network card and wireless network card. The principle is that amplified signal can not amplify power supply.
Specification: The interface of this product is 1.1 speed. If you buy a 2.0 device for watching movies and TV, the speed will slow down. (For example, the resolution of the camera image will decline.) Please read the instructions carefully when you buy it.
This product is powered by USB. USB only provides 5V 5OOMA current. In ultra-long distance transmission, external devices need self-sufficient power supply to achieve 30-50M. If you are a card collector, it may be due to power supply problems and will be unstable. Please read carefully when purchasing.
