Abstract

A retail terminal includes a first terminal cabinet and a second terminal cabinet. The retail terminal includes a controller secured to the first terminal cabinet, the controller having a controller data port associated therewith. The retail terminal also includes a port expander device secured to the second terminal cabinet. The port expander device has a first expander data port, a second expander data port, and a third expander data port associated therewith. The retail terminal also includes a first retail peripheral device secured to the second terminal cabinet. The first retail peripheral device has a first peripheral data port associated therewith. The retail terminal further includes a second retail peripheral device secured to the second terminal cabinet. The second retail peripheral device has a second peripheral data port associated therewith. The controller data port is electrically coupled to the first expander data port via a first data cable. The first peripheral data port is electrically coupled to the second expander data port via a second data cable. The second peripheral data port is electrically coupled to the third expander data port via a third data cable.
