2.2.1 Jumper Description
You may configure AIR-500D to match the needs of your application by setting jump-
ers. 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 connect the pins with the clip. To
open a jumper, remove the clip. Sometimes a jumper will have three pins, labeled 1,
2 and 3. In this case you would connect either pins 1 and 2, or 2 and 3.
The jumper settings are schematically diagrammed in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
