In daily use

Connect the USB Type-A male end to any available USB port on the Sunmi terminal and plug the RJ11/RJ12 male connector into the cash drawer. When a sale is completed, the POS software sends an open command through the adapter, triggering the drawer instantly. The adapter draws power directly from the USB bus, so no external power supply is needed.
