Jumper Description

ARK-1220 can be configured to satisfy specific application requirements 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, connect the pins with the clip. To open a
jumper, remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and
3. For these jumpers, 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 necessary when working with jumpers. Users
with concerns regarding the ideal hardware configuration for your application should
contact your local distributor or sales representative before making any changes.
Generally, only a standard cable is required to make most connections.
