4.1 Jumpers and Connectors
4.1.1 Setting jumpers
You can configure your Point of Care Terminal 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:
1 2 1 2
1
Open Closed Closed 2-3
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.
