+5V*2
*1: The VCC and GND signals are all common.
*2: Outputs +5V power supplied from the +5V pin in the PC to the external device.
The maximum current flowing through these two Vcc pins together is 500mA.
Use this pin to supply +5V power to an external device (such as an encoder) for simple checking.
