6. Operating the reader
Reading and setting the conguration is done via the buttons “Read LED Conguration” and “Set LED conguration”. The conguration
change is done immediately.
If the function access protocol for the LEDs is chosen, it can be adjusted in the submenu LED and residual period for the LED can be
set. With buttons “Switch LED On” the LED is switched on for ms duration. The “Switch LED Off” button switches off the chosen LED.

LEDs
For cascadable SmartShelf antennas an absolute attenuation value is to be entered under the heading “interim cable
loss” (in 0.25 dB steps) for the lines between the antennas. The given value is set with “interim cable loss” to the reader.
Conversely, this can be called up from the reader using the button “Read interim cable loss”.
For cascading smart shelf antennas, it is necessary to use cables with the same attenuation (cable length). Otherwise
the TX-power of the antennas that is derived from the intermediate cable attenuation is not calculated correctly.
Furthermore, the value of the intermediate cable loss should be correct, so that the output power can be correctly cal-
culated and fed accordingly.
The libraries and headerles to support the software integration of the reader into existing applications can be found
on the CD in the /API directory. The user can choose the appropriate library for the target system (windows/ linux/ ELC/
ETL).
As another way of integration the user can implement the KBRP protocol according to the specication ((A)).
The example projects are located in the directory RFIDDemoApp. They demonstrate the programming of applications
for the reader under Windows, Linux and embedded Linux (ELC/ ETL) in C#, C++ and VB.Net. The examples are based
on the use of library functions. This examples are console applications. They show how to establish an connection to
the reader, read tags, use GPIOs and
how action lists are constructed.
