Configuring and Monitoring
4.1.2 RF Configuration
FR900_SDK_DEMOAPP is an example of a PC client application.
Regardless of the application you’re using, the underlying protocol is the same, Low-Level Reader Protocol
(LLRP).
LLRP is a standard, asymmetric, binary protocol used for communication between a client application and
the Reader. LLRP controls the configuration of the antenna transmit power, the receive sensitivity, the
operating Reader, and more. For more information about LLRP, see the following
documents:

Using DemoApp to Configure and Test FR900
BLUEBIRD provides a LLRP application to use to configure and test the basic RF behavior of FR900. The
DemoApp is available from the BLUEBIRD support Web site . To use DemoApp, your computer must be
running a minimum of Windows 7 and have .NET Framework 4.6.1 installed.
This section describes how to connect to and configure a Reader’s RF parameters by using DemoApp. It
also provides a high-level description of each parameter.
To configure and test a Reader by using DemoApp
1. Launch the DemoApp. The screen shown in Figure 4.1 displays.
