Cash Drawer

The Motherboard supports 12V or 24V Cash Drawers on the rear I/O. Dual cash drawers are supported using an adapter. Two cash drawers share a common switch status signal. The port auto-detects drawer voltage and configures the driving circuit for 24V or 12V drawers as appropriate.

Control signals are connected to GPIOs of the PCH. The 24V uses the same fuse type as the +24V USB plus power port.

The CDKO circuit design is a new type that supports both NCR and Radiant cash drawer families. The cash drawer interface circuit supports both 12V and 24V output voltages, selectable in software. A presence detect function signals whether Drawer A, Drawer B, or both are present. Dual drawer splitter devices for Silver are supported, allowing differentiation of whether Drawer A or Drawer B is open.

A 6-position RJ12 connector is used.
