2.2.1 Setting Jumpers

You can configure your ALAD-K2120T(P) to match the needs of your application by setting the jumpers.
A jumper is the simplest kind of electrical switch. 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 pins 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.
