2.2 Jumpers
2.2.1 Jumper Description
ARK-1250L 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 pin 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 about the ideal hardware configuration for their application should con -
tact their local distributor or sales representative before making any changes. Gener -
ally, only a standard cable is required to make most connections.
