The Single Slot Dock is both a USB and a serial communication adapter between the terminal and the host computer.
The Single Slot Dock also functions as a battery charger, both for the terminal and the spare battery pack. The spare battery can be charged by inserting it into the slot at the back of the cradle.
Power supply is required for the Elf or the Falcon X3 to be connected to the cradle and for battery recharging operations.
