Jumper Description

You may configure the MIC-7420 to match the needs of your application 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, you remove the clip. Sometime a jumper
will have three pins, labelled 1, 2 and 3. In this case you would connect either pins 1
and 2, or 2 and 3.
The jumpers setting are schematically depicted in this manual as follows.
