How to present data in client screen?
In order to establish a connection between the POS and external devices, we have an Installer app and external device microservice. Now the last step is to edit configurations of the microservice, so it can be a sort of bridge between all of the moving parts.
Make sure your customer display is connected to the computer via one of the USB ports. It is important to know which port the display is connected to.
To see what port number is used for your customer display on your Windows go to Device Manager and check Ports (COM & LTP ). From there you will be able to see which COM port number is assigned to customer display
Now that the COM port which customer display is connected has been established, we can configure the microservice. For that, go ahead and navigate to the microservice configuration page.
The default expected configuration is already prefilled, COM port was the only field that was needed to edit on the creation of this example.
Scroll down and press the Save button, which rewrites the configuration file.
Test the newly added device on your POS.
