Customer display

To enable your customer display, open settings and select the Customer display section.

Aronium supports two customer display types:

• Pole display - a VFD two-line customer display connected through a COM/serial port.
• Secondary monitor - a full customer screen shown on an additional Windows display, such as an HDMI monitor.

Choose the preferred display type.

Pole display

Select Pole display as the display type, then select the COM port your display is attached to.

Once you have selected the COM port, click Test display to check if everything is set up properly. If the customer display is connected, you will see a test message displayed.

Port settings

Additionally, you can adjust settings for the COM (serial) port where the customer display is connected. In case your customer display is not working correctly, or is displaying unreadable characters, click Show port settings next to the port selection and try adjusting the properties until you see the test message displayed as expected.

In many cases, changing port speed ("Bits per second") only can be enough to fix the problem with unreadable characters displayed.

Welcome message

You can customize your welcome message to show any greeting message in both display lines. To do so, enter your welcome message in the top and bottom line fields.

The welcome message will be displayed on application start and after the sale is complete.

Aronium will also display an item being added to the sale, so this information is clearly presented to the customer.

Secondary monitor

Select Secondary monitor as the display type to show a full customer screen on the second display. In this mode, Aronium does not use COM port settings.

Secondary monitor settings include:

• Advertisement position - choose whether the advertisement media is displayed on the left or right side of the screen.
• Media file - select an optional image or video to show next to the order.
• Page background - set the background color behind the order and media areas.
• Media background - set the background color of the media area.
• Preview on display - open or update the secondary monitor preview without saving and closing the settings screen.

Advertisement media

The media file is optional. If no media file is selected, or if the selected file no longer exists, the media area will be hidden and the order will use the full screen.

Supported media formats include PNG, JPG, JPEG, BMP, GIF, SVG, WEBP, MP4, MOV, and WEBM.

Preview changes

Use "Preview on display" when adjusting the secondary monitor layout, colors, media file, or advertisement position. The preview opens the customer display if it is not already visible, or updates the existing customer display window if it is already open.

Previewing does not save your changes. Click Save to keep the new settings. If you close the settings screen without saving, Aronium restores the previously saved customer display settings.

Sale display

During a sale, the secondary monitor shows the current order items, subtotal, tax, and total. When payment is complete, the screen changes to a payment complete message and shows subtotal, tax, total, and change when change is available.

Troubleshooting

• If a pole display shows unreadable characters, open port settings and try a different "Bits per second" value.
• If the secondary monitor does not appear, check that the display is connected, turned on, and detected by Windows.
• If advertisement media is not displayed, confirm that the selected file still exists and uses a supported media format.
