What Are the Differences Between a Mini USB Interface and a Common USB Interface on the AR series?
The mini USB interface lies next to the console interface on the device. The mini USB interface supports the similar functions as the console interface and is used for configuring the device that is powered on for the first time. The USB interface is used to connect to a USB flash drive for device deployment and system file loading.
All series ARs except the AR150&160&200 series provide a mini USB interface.
