Abstract
Some embodiments include a stand that includes a communication interface, a universal serial bus (USB) microcontroller, and one dual purpose RJ12 interface configured to switch between a cash drawer mode and an RS232 mode. The stand can be configured to be coupled to a main display device. The main display device (e.g., an application running on the main display device) can enable selection of the cash drawer mode for communications via the dual purpose RJ12 interface, and receive an input signal after the selection. The main display device can enable selection of the RS232 mode for communications via the dual purpose RJ12 interface based on the input signal and transmit an indication to the stand, where the dual purpose RJ12 interface is configured to operate in the RS232 mode. The stand can include a hinge structure that enables the main display device to be flipped to face an opposite direction.
