5口集线器(HUB)使用说明书
HUB(集线器)
HUB,也就是集线器。
它的作用可以简单的理解为将一些机器连接起来组成一个局域网。
而交换机（又名交换式集线器）作用与集线器大体相同。
但是两者在性能上有区别：集线器采用的式共享带宽的工作方式，而交换机是独享带宽。
这样在机器很多或数据量很大时，两者将会有比较明显的。
而路由器与以上两者有明显区别，它的作用在于连接不同的网段并且找到网络中数据传输最合适的路径，可以说一般情况下个人用户需求不大。
路由器是产生于交换机之后，就像交换机产生于集线器之后，所以路由器与交换机也有一定联系，并不是完全独立的两种设备。
路由器主要克服了交换机不能路由转发数据包的不足。
总的来说，路由器与交换机的主要区别体现在以下几个方面：（1）工作层次不同最初的的交换机是工作在OSI／RM开放体系结构的数据链路层，也就是第二层，而路由器一开始就设计工作在OSI模型的网络层。
由于交换机工作在OSI的第二层（数据链路层），所以它的工作原理比较简单，而路由器工作在OSI的第三层（网络层），可以得到更多的协议信息，路由器可以做出更加智能的转发决策。
（2）数据转发所依据的对象不同交换机是利用物理地址或者说MAC地址来确定转发数据的目的地址。
而路由器则是利用不同网络的ID号（即IP地址）来确定数据转发的地址。
IP地址是在软件中实现的，描述的是设备所在的网络，有时这些第三层的地址也称为协议地址或者网络地址。
MAC地址通常是硬件自带的，由网卡生产商来分配的，而且已经固化到了网卡中去，一般来说是不可更改的。
而IP地址则通常由网络管理员或系统自动分配。
（3）传统的交换机只能分割冲突域，不能分割广播域；而路由器可以分割广播域由交换机连接的网段仍属于同一个广播域，广播数据包会在交换机连接的所有网段上传播，在某些情况下会导致通信拥挤和安全漏洞。
连接到路由器上的网段会被分配成不同的广播域，广播数据不会穿过路由器。
虽然第三层以上交换机具有VLAN功能，也可以分割广播域，但是各子广播域之间是不能通信交流的，它们之间的交流仍然需要路由器。

集线器(Hub)
集线器(Hub)一、概述二、谁需要集线器三、集线器的类型一、概述正如其名字所暗示的，Hub就是活动的中心。
用网络术语来说，Hub 或Concentrator，是基于星形拓扑的接线点。
Arcnet、10Base-T、10Base-F及许多其它专用网络都依靠集线器来连接各段电缆及把数据分发到各个网段。
集线器的基本功能是信息分发，它把一个端口接收的所有信号向所有端口分发出去。
一些集线器在分发之前将弱信号重新生成，一些集线器整理信号的时序以提供所有端口间的同步数据通信。
具有多个10Base-F接口的集线器就象是使用镜子来把光线分到各个端口。
图1是基本的10Base-2网络，注意机器间连接的方式和数据在源设备和目的设备间的各个设备的处理及传递。
图2是与图1相同的网络，不过是10Base-T，可以看到拓扑的不同和集线器是如何嵌到此网中。
在10Base-T网络中，所有设备需要用非屏蔽双绞线连接到一个或多个集线器，集线器应该有多个端口甚至多种类型的端口。
有时需要把多个集线器连接起来，这时，你可能想用高速端口来建立网络的主干，各集线器与服务器应直接连到高速主干上。
因为多数LAN的主要通信是在工作站和主服务器之间的，主干对网络的整体性能意义重大。
图3是个较复杂的10Base-T网络示意图，注意主干是怎样连接多个集线器和服务器的。
主干应该是高速连接，如快速以太网或FDDI等。
令牌环网中也有可以称作集线器的设备，MSAU(Multi-Station Access Unit)就可以看作一种集线器，因为它的功能与以太网的集线器很类似，但是MSAU把包串行地路由到各个设备，不象以太网集线器是并行的。
为了不发生混淆，令牌环网MSAU不作为集线器讨论。
二、谁需要集线器？判断你的局域网是否需要集线器的方法很简单：如果你想建立星形网络且有不少于两台主机，那么就需要集线器。
这个规则只有一个例外，那就是只有两台主机的10Base-T网络，可以直接将之相连，但是需要一条特殊发送端与接收端交叉连接的线缆，这种线缆很普通，如果你实在找不到，也可以自己做一个，很容易也很便宜，所需物品为一小段双绞线、两个RJ-45接头和工具，按照下表连接就是了。

For this installation, Toggle Mode is recommended. 6. T est receiver. (If receiver is not working, review wiring and programming instructions).7. Stow all wires in wiring box. Finish any installation of fixture or wall switch.PROGRAMMING:The receiver must be powered when programming. After programming, settings are retained when power isdisconnected. The receiver sensitivity is reduced when in Learn Mode to prevent unintentionally associatingunwanted transmitters with the receiver. Transmitters should be within 15 feet (5 meters) of the receiver when programming. Program the receiver in any of the modes below.Rocker Mode (default): In Rocker Mode the receiver responds only on a transmitter press and not on the release. For example, one side of the rocker on a wireless light switch will activate the relay (turn the light ON) when pressed and the opposite side of the same rocker will deactivate the relay (turn the light OFF)when pressed.Momentary Mode: In Momentary Mode, each end of the rocker on a wireless light switch acts as a separatebutton. Each end of the rocker programs separately to 1 or more receivers. When a rocker is pressed the output on the receiver will activate (turning the electrical load ON). When the rocker is released the output will deactivate (turning the electrical load OFF).Toggle Mode: In Toggle Mode, each end of the rocker acts as a separate button. Each end of the rockerprograms separately. When the rocker is pressed the output of the receiver will always change state (if OFF,it will turn ON; if ON, it will turn OFF). Like Rocker Mode, the output status only changes when a button ispressed and is ignored on the release.Follow the instructions below for the desired programming mode:Rocker Mode (default) Programming Instructions 1. R ead all Rocker Mode programming steps before taking any action to program receiver in Rocker Mode.2. A ctivate Rocker Learn Mode by pressing and holding the LRN button for 1 second (See Figure A). The electrical load connected to the receiver will begin turning ON and OFF in a slow pattern.3. W hen associating a wireless light switch with the receiver, press one end of a switch rocker (See FigureB). When associating a transmitter other than a wireless light switch, press the LRN or TCH button on the Leviton transmitter (see appropriate transmitter starter guide). The load will stay ON for about 3 seconds indicating that the receiver has stored the transmitter’s unique ID in its memory.4. N OTE: If only one transmitter is desired then skip Step 4 and exit Learn Mode by following Step 5. To associate a second transmitter with this receiver, wait until toggling of the load resumes. Repeat the instructions in Steps 3 and 4 until the unique IDs of all desired transmitters are stored in the memory of the receiver.WARNINGS AND CAUTIONS:• DISCONNECT POWER AT CIRCUIT BREAKER OR FUSE WHEN SERVICING, INSTALLING ORREMOVING FIXTURE.• TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH ELECTRICAL CODES ANDREGULATIONS.• IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS, CONSULT AN ELECTRICIAN.• RELAY RECEIVERS ARE INTENDED ONLY FOR USE INDOORS, IN DRY LOCATIONS, AND WITHPERMANANTLY INSTALLED FIXTURES.• SUITABLE FOR USE ON A CIRCUIT CAPABLE OF DELIVERING NOT MORE THAN 15 RMSSYMMETRICAL AMPERES MAXIMUM.• RELAY RECEIVERS SHOULD NOT BE INSTALLED IN LOCATIONS WHERE THE UNITS WILL BE INCLOSE PROXIMITY TO THE LIGHT BULB(S) OR OTHER SOURCES OF HEAT, SUCH AS ABOVE ACEILING HUGGER FIXTURE, PARTICULARLY WITH HIGHER WATTAGE LOADS.• WHEN USING RELAY RECEIVERS TO SWITCH A MOTOR, OVERLOAD AND OVER-CURRENTPROTECTION SIZED FOR THE MOTOR LOAD SHOULD BE PROVIDED AT THE BRANCH CIRCUITFEEDER SUPPLYING THE MOTOR IN ACCORDANCE WITH THE NEC OR CEC, AS APPLICABLEFOR THE INSTALLED LOCATION.• THE MAXIMUM OVER-CURRENT PROTECTION REQUIRED FOR THE BRANCH CIRCUIT SUPPLYING THIS PRODUCT IS 15 AMPS.

The receiver is now in Momentary Learn Mode.3. Follow Steps 3-5 of "Rocker Mode Programming Instructions."Toggle Mode Programming Instructions1. Read all Rocker and Momentary Mode programming steps before taking any action to program receiverin Toggle Mode.2. While the receiver is in Momentary Learn Mode, press and hold the LRN button for 3 seconds(See Figure A). The electrical load connected to the receiver will continue turning ON and OFF in a fast pattern. The receiver is now in Toggle Learn Mode.3. Follow Steps 3-5 of "Rocker Mode Programming Instructions."Selective Deleting: Follow the Program Mode steps above to delete a transmitter from a receiver’s memory. Upon pressing the LRN button on a transmitter (See Rocker Mode Programming Instructions, Step 3) which has previously been associated with the receiver, the electrical load connected to the receiver will stay OFF for 3 seconds indicating that the receiver has removed the transmitter’s unique ID from its memory.Clear All: If the CLR button is pressed and held for 2 seconds (See Figure C), the entire memory of the receiver will be deleted. The receiver will instantly enter the default programming mode (Rocker Mode) indicated by the electrical load turning ON and OFF.Automatic ON / Automatic OFF. If the receiver learns a wireless motion sensor, the load will turn OFF after no occupancy has been detected for 15 minutes. If learned in the Rocker Mode, the output will be Manual ON / Automatic OFF. If learned in Momentary Mode, the output will be Automatic ON / Automatic OFF.ADDITIONAL PROGRAMMING OPTIONSInverted Output Mode: The receiver supports the Inverted Output Mode of operation. In the defaultconfiguration, the N.O. relay contact is open (not connected) when not active, and closed (connected) when active. When the outputs are in Inverted Output Mode, the N.O. contact is closed when not active and open when active. Inverting the outputs may be used to emulate a normally closed relay that opens when a switch is activated.One common use for this mode is for magnetic door release controls. The output is ON and the door-hold electromagnet is active until a Momentary switch is activated, deactivating the electromagnet and allowing the door to close. The magnet is reactivated as soon as the switch is released.Inverted Output Mode Programming Instructions 1. Turn the power to the receiver OFF.2. Press and hold the CLR button for 5 seconds while turning on the power. The load will blink twice toindicate activation of Inverted Output Mode.To change back to normal operating mode, repeat Steps 1 and 2. The load will blink once to indicatenormal (non-Inverted) mode. The state of this mode is stored in non-volatile memory and is maintained even if the power is removed.Repeater Function (WST models only): The default setting for the receiver is Repeater-ON. A repeater re-transmits a copy of every signal received, and many repeaters also function as receivers. It isrecommended that no more than two repeaters are active within range of any LevNet RF transmitters or receivers. Repeaters should be installed high above the floor in a central location, minimizing the number of walls or other obstructions through which the wireless signal must travel.Repeater Programming Instructions:1. Turn the power to the receiver OFF 2. P ress and hold the LRN button for 5 seconds while turning on the power. The load will blink twice toindicate activation of the repeater mode. T o change back to normal operating mode, repeat Steps 1 and 2. The load will blink twice indicate therepeater is ON and blink once to indicate the repeater is OFF.PK-93717-10-00-0B ARN1401For Technical Assistance Call: 1-800-824-3005 (U.S.A.

Hubport 2.0 自电 USB 集线器用户手册说明书
Hubport Installation GuideIntroductionThank you for purchasing the Hubport ™, a self-powered Universal Serial Bus (USB) hub designed to provide a convenient and effective means of bringing USB connectivity to your PC, server, or laptop. The Hubport also delivers the potential of Inside Out Network’s flagship product — the Edgeport ™ USB to Serial (RS-232) expansion module.Hubs, critical components in the plug-and-play architecture, are wiring concentrators that enable the attachment of multiple devices, thus converting a single attachment point into multiple attachment points. USB architecture allows a cascaded multiple hub configuration with certain power limitations (explained later in this section). See figure 1.Each hub has an upstream port, connecting to the host, and multiple downstream ports, connecting to downstream devices,including other hubs. A hub can detect attachment and detachment of downstream devices and enable and monitor the distribution of the power to downstream devices via their integral hardware and the operating system.Each USB device reports its power requirements to the operating system, which then enables and disables the device as a function of its power requirements and the amount of available power. High-speed devices typically need to be connected to a self-powered hub, such as the Hubport, which obtains power from its external power supply and provides up to 500 mA for each downstream port. Only simple devices, such as a mouse, can be connected to a bus-powered hub, which obtains power from its upstream host and provides up to 100 mA for each downstream port.Due to the limited available power for bus-powered hubs, cascading two bus-powered hubs is an illegal topology, and devices connected to the second hub will not function. (USB specifications limit the connection of a bus-powered hub to a self-powered hub or host only.) Since the Hubport is a self-powered hub, it is not affected by this limitation.Verifying Correct Installation of USBSupportIf you are using Windows 98, which fully supports USB, you may proceed to “Installing Hubport.” If you are using Windows 95 OSR2.1 or above,please continue with the section below.Checking for Full USB Support in the Device Manager1)From the main desktop area of Windows, right click on the My Computer icon and choose Properties to open the System Properties window.2)Click once on the Device Manager tab to view a listing of installed hardware devices.Figure 1: Example of a Typical Hub ConfigurationPCHOST HubportHubportEdgeportEdgeportEdgeportscannerbus-powered hubjoystick mouseFigure 2: Example of the USB Devices Listed in theDevice Manager Tab3)In the Device Manager tab, your hardware devices are in alphabetical order and should include a Universal serialbus controller toward the bottom of the list. Double click on this device to open it.In order for the Hubport and other USB devices to work properly at least two devices are required and will be listed. Although the exact name of each manufacturer’s device listing can vary, the names of these two required USB devices should include the following descriptive words:•USB Root Hub•USB Host ControllerFigure 2 shows an example of what you might see listed under the Universal serial bus controller. If you do not see one or both of these devices, go to “Determining Why Support Is Not Present.”Installing HubportPlugging Hubport Into Your PCPlug in the power supply. Plug the flat end of the UBS cable into the downstream A connector located in the back of your computer or USB hub port. Plug the D-shaped end into the Hubport.If previously installed, the Hubport will be listed in the System Device Manager and is ready for immediate use. With the initial installation, the Update Device Driver Wizard automatically appears and you may continue with “Installing the Drivers” below. If the Update Device Driver Wizard does not appear, go to the preceeding section, “Verifying Correct Installation of USB Support.”Installing the DriversTo install your Hubport drivers:1Click on NEXT to initiate a search for the updated driver device.2)Click on FINISH to continue with the installation.You have now successfully installed your Hubport!Determining Why Support Is Not PresentTo verify that the necessary hardware, a USB Host Controller, is installed in your system, make sure that your PC has USB connectors. If not, then this system will not support USB regardless of the Windows version. You will need to purchase a PCI USB controller card, such as the Step Up Kit™ from Inside Out Networks. If your PC has USB connectors, verify that the USB hardware is enabled in your system BIOS configuration.In some cases your manufacturer may have elected to ship your PC without the USB support drivers installed. If the two USB device manager hardware listings are absent in your Device Manager, proceed to the next section, “Installing Microsoft USB Support.”After installing USB Support from your Microsoft Windows 95 OEM system disk, check your Device Manager again. If the two devices are not present or Windows Plug & Play does not auto detect the Hubport, try the following:1)If only the HOST Controller is listed in the Device Manager then remove it and reboot.2)From the Control Panel, open the System Properties and select “Check for a device labeled ?UNKNOWN.” IfROOT HUB and HOST Controller are listed, then remove them and reboot.If, after rebooting, the Add Hardware Wizard finds the USB devices and requires new drivers, such as UHCD.SYS, you can locate the drivers in the C:\WINDOWS\SYSTEM directory. If, after following the proceedures decribed in this guide, you still cannot install you Hubport, please call (512)301-7080 and ask for Technical Support.Installing Microsoft USB SupportMicrosoft provides a supplemental program (usbsupp.exe) to allow users to upgrade Windows 95 version OSR2 to support the Universal Serial Bus. In order to install this support perform the following steps:1)Insert your Microsoft Windows 95 OEM system disk into your CD drive.2)In the START menu, select RUN.3)Type <CD drive letter>:\other\usb\usbsupp.Follow the instructions on the screen.After rebooting, continue with the “Installing Hubport” section.Note that Windows 95 version 4.0.950 and 4.0.950a do not support the upgrade path to USB. Unfortunately, Microsoft has not provided an upgrade path to OSR2 from earlier versions of Windows. OSR2 must be preinstalled by your PC vendor. Contact your PC vendor for more information.Copyright © 1998 by Inside Out Networks.

集线器(HUB)) 功能介绍 及选型
集线器（HUB）是对网络进行集中管理的重要工具，像树的主干一样，它是各分枝的汇集点。
HUB是一个共享设备，其实质是一个中继器，而中继器的主要功能是对接收到的信号进行再生放大，以扩大网络的传输距离。
在网络中，集线器主要用于共享网络的建设，是解决从服务器直接到桌面的最佳、最经济的方案。
在交换式网络中，HUB直接与交换机相联，将交换机端口的数据送到桌面。
使用HUB组网灵活，它处于网络的一个星型结点，对结点相连的工作站进行集中管理，不让出问题的工作站影响到整个网络的正常运行。
由于HUB在网络中的重要作用，所以对于它的选型也是非常重要的。
下面，就让我们针对此做一番深入的剖析：一．以带宽为选择标准：根据带宽的不同，目前市面上用于局域网（一般是指小型局域网）的HUB可分为10MB、100MB和10/100MB自适应三种。
在规模较大的网络中，还使用1000MB和100/1000MB自适应两种。
集线器带宽的选择，主要决定于三个因素：1、上连设备带宽:如果上联设备支持IEEE802.3U（允许跑100M），您自然可购买100M集线器，否则只有选择10M的了。
2、站点数：由于联在集线器上的所有站点均争用同一个上行总线，处于同一冲突域内，所以站点数目太多，造成冲突过于频繁。
3、应用需求：由于现在10M非智能型HUB的价格已经接近于款网卡的价格，并且10M的网络对传输介质及布线的要求也不高，所以许多喜欢"DIY"的网友完全可以自己动手，组建自己的家庭局域网或办公局域网。
在前些年组建的网络中，10M网络几乎成为网络的标准配置，有相当数量的10M HUB作为分散式布线中为用户提供长距离信息传输的中继，或作为小型办公室的网络核心。
但这种应用在今天已不再是主流，尤其是随着100M网络的日益普及，10M网络及其设备将会越来越少。
虽然纯100M的HUB给桌面提供了100M的传输速度，但当网络升级到100M 后，原来众多的10M设备将无法再使用，所以只有在近期才开始组建的网络，才会无任何顾虑地考虑100M的HUB。
