The Jumper column allows you to specify the state of a jumper or series of jumpers on the top-level schematic. This column is useful for making changes to the schematic topology when the components cannot be altered with a Var(), GlobalVar(), or Change() function.
The jumper symbols have either one or two positions and can have up to 64 poles. Through the testplan, jumper positions can be changed on a test-by-test basis to provide additional flexibility in configuring the schematic.
The process for using jumpers consists of two basic additions to the testplan.
where Close() is a synonym for Pos1().
