4.1 Jumpers and Connectors
4.1.1 Setting Jumpers
UTC-315 POS can be configured according to the application requirements by set-
ting jumpers. A jumper is the simplest type of electrical switch. Jumpers consist of
two metal pins and a small metal clip (typically protected with a plastic cover) that
slides over the pins to connect them. To “close” a jumper, connect the pins using the
clip. To “open” a jumper, remove the clip. Some jumpers have three pins, which are
labeled 1, 2,
and 3. In such cases, connect either Pins 1 and 2 or Pins 2 and 3.

A pair of needle-nose pliers may be necessary when working with jumpers. If you
have concerns regarding the best hardware configuration for your application, con-
tact your local distributor or sales representative before making any changes.
