JTL-Links

Thank you for using the English version of the JTL-Guide!
We are currently still building up the English documentation; not all sections have been translated yet. Please note that there may still be German screenshots or links to German pages even on pages that have already been translated. This guide mostly addresses English speaking users in Germany.

Note: On 1 September 2024, JTL introduced new editions that bundle most of the previous individual services into different packages. In order for you to continue working as smoothly as possible, existing customers were automatically switched to the package configuration that best matched their existing contract. The individual packages differ in terms of limitations and/or range of functions. Therefore, some of the features described in the JTL-Guide may not be available to you as part of your booked JTL edition. You can change your package configuration in your JTL customer account. Find out more about the new editions and packages here. Check our FAQ for frequently asked questions about the product editions.

Setting up JTL-POS CustomerDisplay

Your task/initial situation

You use JTL-POS on a stationary device that can only be viewed by your cashier. However, you would like to show your customers important information about the items that have been placed on the receipt. To do this, use JTL-POS CustomerDisplay on a second device that can be viewed by the customer.

Requirements

You need two separate Android devices. One on which you run JTL-POS and a second one for JTL-POS CustomerDisplay.
Both devices must be part of the same network, e.g. WLAN.
Alternatively, you can connect a second display to the device on which you use JTL-POS.

System requirements

Operating system: Android 7.0
Processor: 1.0 GHz; Dual-Core
RAM (working memory): 100 MB
Internal storage space: 100 MB

Downloading and installing the app

On the device on which you want to run JTL-POS CustomerDisplay, open the app in the Google Play Store: Go to Google Play Store.
Select Install. The app will be downloaded and installed on your device.

Connecting the display with JTL-POS

Open the installed JTL-POS CustomerDisplay app and click Connect.

If you have not connected the app to another device, you can see the IP address of the device.

Open JTL-POS on the other device and click Displays in the menu. The Manage displays area opens.

Tap on the button Add display (plus icon). The Display area opens.
Enter a name for the display into the Name field and enter the IP address that is displayed on the other device in JTL-POS CustomerDisplay into the IP address field.

You have now successfully set up the JTL-POS CustomerDisplay. Read here how you can configure it individually: Managing displays.
