Peripheral Control Interface
A fan for system cooling and a power supply with power management can be connected via
the peripheral control connector J13.
The following figure and table provide pinout information for the power connector J13.
Note ...
Pin 5 is an open drain output and has no pull-up resistor on the CP-RIO3-04
Rear I/O module. Therefore, for fan control operations, an external pull-up
resistor is required.
