Alternative user interfaces

A.3.1

User-defined user interface

The supplied user interface and HTML pages are ideal tools for classic operator control and
monitoring tasks. For applications that are not covered by these tools, we recommend that
you create a user-defined user interface. The basis of these user-defined user interfaces is
the Web API communication of the Web server of the optical readers, which has been
standardized for the optical readers.
WebAPI communication is independent of the target hardware on which the user interface
will run. This means that you have numerous options. For example, you can program .NET
applications for the PC or apps for mobile end devices.
HTML pages with JavaScript in particular represent one special option. You can adapt the
HTML pages to your needs and upload them to the optical readers. You can access these
HTML-based, installed user interfaces from any Web browser.
An example of an HTML-based, user-defined user interface is already stored on optical
readers as of firmware V5.1. Based on this example, modifications or expansions can then
be made.
Requirements and notes on the development of user-defined user interfaces
● The optical reader must have firmware V5.1 or higher.
● The documentation of the standardized WebAPI communication does not ship with the
product. It is intended for experienced developers and requires experience in Web-based
development of user interfaces.
● You will find information on uploading/downloading and access protection of the user-
defined user interface in the online help under the entries "Maintain" and "Connections"
(keyword "Custom GUI").
