4.1 Jumpers and Connectors
4.1.1 Setting Jumpers
Users can configure the UTC-315 to match their application needs by setting jump-
ers. A jumper is the simplest type of electrical switch and consists of two metal pins
and a small metal clip (typically 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,
simply remove the clip. Some jumpers have three pins, 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 helpful when working with jumpers. If you have
any concerns regarding the optimum hardware configuration for your application,
contact your local distributor or sales representative before making any changes.
