2.2 Jumpers and Connectors
Setting jumpers
You can configure your PCA-6654/6654L to match the needs of your
application by setting 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.
