Abstract: A wiring hub for a retail terminal system provides an interface between a main terminal of the retail terminal system and a plurality of peripherals associated with the retail terminal system, such as an input device, a scanner, a printer, and a customer display. The wiring hub provides a centralized chassis containing a plethora of connectors for power distribution to each peripheral and the main unit/terminal and for communication between each peripheral and the main terminal. Each peripheral includes a single cable having integrated power and communications wiring that attaches to appropriate connectors of the wiring hub. The wiring hub is coupled to a source of electricity and includes appropriate electricity routing and conversion for AC and DC peripherals/components. The main terminal is coupled to the wiring hub via one or two cables carrying power wiring, network wiring, and communication wiring. The wiring hub also provides a network connection for the main terminal.
