2.2.1 Setting Jumpers

You can configure your KMDA-3201 to match the needs of your application by setting the jumpers or
switches. A jumper is the simplest kind of electrical switch. 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 you 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
pins 2 and 3.
The jumper settings are schematically depicted in this manual as follows:
