 各种连接网线的制作方法 | ADSL配置程序

  100BaseT连接双绞线,以100Mb/S的EIA/TIA 568B作为标准规格。
  制作步骤如下:

  步骤 1:利用斜口错剪下所需要的双绞线长度,至少 0.6米,最多不超过 100米。然后再利用双绞线剥线器(实际用什么剪都可以)将双绞线的外皮除去2-3厘米。 有一些双绞线电缆上含有一条柔软的尼龙绳,如果您在剥除双绞线的外皮时,觉得裸露出的部分太短,而不利于制作RJ-45接头时,可以紧握双绞线外皮,再捏住尼龙线往外皮的下方剥开,就可以得到较长的裸露线。

  步骤2:剥线完成后的双绞线电缆分开线对。
步骤3:接下来就要进行拨线的操作。将裸露的双绞线中的橙色对线拨向自己的前方,棕色对线拨向自己的方向,绿色对线剥向左方,蓝色对线剥向右方。
上:橙 左:绿 下:棕 右:蓝

  步骤4:将绿色对线与蓝色对线放在中间位置,而橙色对线与棕色对线保持不动, 即放在靠外的位置。

  调整线序为以下顺序: 左一:橙 左二:蓝 左三:绿 左四:棕
  步骤5:小心的剥开每一对线,白色混线朝前。因为我们是遵循EIA/TIA 568B的标准来制作接头,所以线对颜色是有一定顺序的。

需要特别注意的是,绿色条线应该跨越蓝色对线。这里最容易犯错的地方就是将白绿线与绿线相邻放在一起,这样 会造成串扰,使传输效率降低。 左起:白橙白绿白蓝绿白棕 常见的错误接法是将绿色线放到第4只脚的位置。

  应该将绿色线放在第6只脚的位置才是正确的,因为在100BaseT网络中,第3只脚与第6只脚是同一对的,所以需要使用同一对线。(见标准EIA/TIA 568B) 左起:白橙/橙/白绿/蓝/白蓝/绿/白棕/棕
  步骤 6:将裸露出的双绞线用剪刀或斜口钳剪下只剩约 14mm的长度,之所以留下这个长度是为了符合EIA/TIA的标准,您可以参考有关用RJ-45接头和双绞线制作标准的介绍。最后再将双绞线的每一根线依序放入RJ-45接头的引脚内,第一只引脚内应该放白橙色的线,其余类推.

  步骤7:确定双绞线的每根线已经正确放置之后,就可以用RJ-45压线钳压接RJ-45接头,市面上还有一种RJ-45接头的保护套,可以防止接头在拉扯时造成接触不良。使用这种保护套时,需要在压接RJ-45接头之前就将这种胶套插在双绞线电缆上。

  步骤8:重复步骤2到步骤7,再制作另一端的RJ-45接头。因为工作站与集线器之间是直接对接,所以另一端RJ-45接头的引脚接法完全一样。完成后的连接线两端的RJ-45接头无论引脚和颜色都完全~样,这种连接方法适用于ADSL MODEM和计算机网卡之间的连接,计算机与集线器(交换机)之间的连接。完成的RJ45接头应该如下图所示。

  交叉网线用于ADSL MODEM和集线器HUB的连接(与MODEM设计有关系,并非全部如此),HUB与HUB之间不通过级连口的连接,以及两台计算机直接通过网卡相互连接。制作方法和上面基本相同,只是在线序上不像568B,采用了1-3,2-6交换的方式,也就是一头使用568B制作,另外一头使用568A制作,如图:

Windows 3.1/95 Printer Driver - v1.0

1.0 Overview
============
This printer driver allows you to print documents from any Windows
application to your MultiSpot Network Printer. Separate
drivers are provided for Windows 3.1 and Windows 95. You should
install the driver that matches your version of Windows.

2.0 System Requirements
=======================
The MultiSpot Network Printer requires that
a Canon Network Interface Device (NID) be installed on the
parallel input port and the NID needs to be connected to your
network. The NID must be configured for the proper communication
protocol and frame type before printing. Included with your
software is a copy of Canon NetSpot v2.3.1 Network Configuration
Utility. Please see the MultiSpot Network Printer User's Guide
for instructions on installing and using NetSpot. Detailed
NetSpot information can be found in the NetSpot User's Guide,
which is on your CD-ROM in the file GUIDE-E.pdf. This file is in
Acrobat Reader format. A copy of Reader is also on the CD-ROM for your convenience.

1. For Windows 3.1, the minimum amount of RAM memory required is
4 MB, although 8 MB is recommended. For Windows 95, the
minimum amount of RAM memory required is 8 MB, although 16 MB
is recommended. Increasing the amount of RAM memory will
result in faster printing and reduce compatibility problems
with some applications. As an alternative, you can increase
the amount of virtual memory to reduce the possibility of "low
memory" conditions (although this does not improve printing
performance).
2. Allow at least 20 MB of free hard disc space on the drive that contains your system's TEMP directory for Windows 3.1 and 40 MB for Windows 95.
3. The workstation used for loading NetSpot and configuring the
printer has additional requirements. You need at least 16 MB
of memory and 40 MB of free hard disc space.

3.0 Specific Information for Windows 95 Users
=============================================
3.1 Installing the Printer Driver
---------------------------------
To use this printer driver with software application packages that operate with Microsoft Windows 95, use the following installation procedure:

Installing from NetSpot printer configuration utility
It is necessary to install the NetSpot printer configuration utility before installing FAX-L800/L900 Printer Driver.

1. Start Windows 95 on your system.
2. Start NetSpot and Click Windows and select "IPX Device".
Confirm that your FAX-L800/L900 printer status is ready.
3. Click "Device" menu and point to the "Install Driver...".
4. Double-click on the "Add Printer" icon to start
the "Add Printer Wizard".
5. Click "Next" button.
6. Click "Network Printer" radio button and click "Next" button.
7. Click "Browse..." and select your FAX-L800/L900 print queue and then click OK button.
8. Click "Next" button.
9. Click "Have Disk" button.
Click "Browse..." button and specify the directory
<//Netspot/Drivers/Lc9000/Win95/> where the FAX-L800/L900
Printer Driver for Windows 95 is located on your computer's
hard disc drive.
10. Click OK to the "Install From Disk" dialogue.
11. Click OK and follow the instructions of Add Printer Wizard
until the installation is finished. The FAX-L800/L900
Printer Driver icon will then appear in the Printer folder.
