To enable your customer display, open settings and select "Customer display" section.
In this section, check "Enabled" option and select COM port your display is attached to.
Once you have selected COM port for customer display, click "Test display" button to check if everything is set up properly. If customer display is connected you will see a test message displayed.
You can customize your welcome message to show any greeting message in both display lines. To do so, enter your welcome message in top and bottom line fields.
Welcome message will be displayed on application start and after sale is complete.
Also, Aronium will display an item being added to the sale, so this information is clearly presented to the customer.
