Jumper Description/ 跳线说明
2.3.1
You may configure the ITA-2000 to match the needs of your application by setting
jumpers. A jumper is a metal bridge used to close an electric circuit. It consists of two
metal pins and a small metal clip (often protected by a plastic cover) that slides over
the pins to connect them. To close a jumper, you remove the clip. Sometime a jumper
will have three pins, labeled 1, 2 and 3. In this case you would connect either pins 1
and 2, or 2 and 3.
用户可以根据应用需要通过设置跳线进行 ITA-2000 配置。板卡可以通过设置跳线进行
配置。跳线是用来连通电路的金属桥。它包括 2 个金属针脚和一个跳线帽 （里面是金
属夹片，外部是起保护作用的塑料套） 。跳线帽可套住针脚将其连成通路。移走跳线帽
则会断开线路。有时，一个跳线具有 3 个针脚，分别为针 1、2、3。这种情况下，用
户可以任意选择连接针脚 1、2 或者针脚 2、3。
The jumpers setting are schematically depicted in this manual as follows.
设备的跳线设置如下图所示：
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
进行跳线设置时，使用针鼻钳可能会有所帮助。若用户对应用的最佳硬件配置产生任
何疑问，请在进行更改前联系当地的分销商或销售代表。一般情况下，多数连接仅需
要一根标准电缆。
