Switches and Jumpers
The product has several jumpers which must be properly configured to ensure correct operation.
Figure 31: Jumper Connector
For a three-pin jumper (see Figure 35), the jumper setting is designated “1-2” when the jumper connects pins 1 and 2.
The jumper setting is designated “2-3” when pins 2 and 3 are connected and so on. You will see that one of the lines
surrounding a jumper pin is thick, which indicates pin No.1.
To move a jumper from one position to another, use needle-nose pliers or tweezers to pull the pin cap off the pins
and move it to the desired position.
