2.2.1 Setting Jumpers
You can configure your KMDA-3601 to match the needs of your application by setting the jumpers. 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.
