Setting Jumpers and DIP Switches
There are jumpers and DIP-switches on the system board of the
MBATX-845GV-VEAH Series. You can set the jumpers to make the
necessary operations.
Figure 7: Jumper Connector
For any three-pins jumpers (Figure 7), the jumper setting is 1-2 when the
jumper connects pin 1 and 2. The setting is 2-3 when pin 2 and 3 are
connected and so on. You see a number “ 1 “ and a “ 3 “ printed on the circuit
board to identify these pins. And also, there is a second way of indication –
one of the lines surrounding jumpers 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.
