2.2.1 Jumper Description
ITA-460 can be configured for specific applications by setting jumpers. A jumper is a
metal bridge used to close an electric circuit. 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, remove the clip. Some jumpers may have three pins,
labelled 1, 2, and 3. For these jumpers, 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 about the best hardware configuration for your application, contact
your local distributor or sales representative before making any changes. For most
connections, only a standard cable is required.
