NCA-5230 User Manual
The motherboard layout shows the connectors and jumpers on the board. Refer to the following picture as a
reference for the pin assignments and the internal connectors.
The pin headers on the motherboard are often associated with essential functions. With the shunt (Jumper)
pushed down on the designated pins (the pin numbers are printed on the circuit board, surrounding the pin
header), particular features can be enabled or disabled. While changing the jumpers, make sure your system is
turned off.
Jumper Setting
To short the designated pins, push the jumper down on them so that they become SHORT. To make the pins
setting OPEN, simply remove the jumper cap.
