Configuration

Allow detection

Allow alarm

A preference needs to be configured by setting a numeric value in milliseconds. When the drawer gets open and after the value previously inserted an alarm will begin to sound. If there are no value or it is 'N', no alarm will rise.

Web POS Time Allowed Drawer Sales is configured for the events of opening the drawer from sales or menu.

Web POS Time Allowed Drawer Count is configured for the event of opening the cash drawer from Cash Up, Cash Management or Initial Count.

Hardware url

In order to use this functionality Hardware url MUST be configured properly on POS Terminal window.
