2.2 Jumpers

2.2.1 Jumper Description

You may configure the ARK-3390 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 connect the pins with the clip. To

open a jumper, you remove the clip. Sometimes 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.

The jumper settings are schematically depicted in this manual as follows.

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.
