3.1 Overview
Functionality of the programming interface
The functionality of the programming interface is available for the RTLS4083T transponder.
The programming interface of the transponder is a functionality supported by the Locating
Manager. It enables external client applications to communicate with the transponder via the
Locating Manager Server. The transponder can be accessed via WAMP (Web Application
Messaging Protocol) independent of the operating system or the code language of the external
client.
Additional functions of the transponder
In addition to the basic function of its use as a localizable node, the transponder o󹪜ers additional
functions such as "ePaper display" or "Control keys", which can be used by the external client
applications. The display content is managed via "Themes". A transponder Theme contains a
background graphic and various form 󹪝elds to display text and barcode. A form 󹪝eld is a text
󹪝eld on the display of the transponder with the following con󹪝gurable properties:
Field type
Text 󹪝eld

Project-speci󹪝c requirements for the con󹪝guration of the "Themes" as well as the download of
the con󹪝guration to the transponder can be performed during operation. Optionally, the
con󹪝guration of the "Themes" can be transferred from the manager to the transponder.
