GPIO Functions
Readers with GPIO functionality1) offer the possibility to set up small controls which trigger the reader, for
instance by means of a light barrier, or which trigger an action at the outputs of the reader by reading specific
tags. Such an action can switch an output to control the flow of goods.
The GPIO tab allows the reader to interact with its environment. The GPIO function tab allows the user to
manually read or switch inputs and outputs of the respective application. For more complex procedures, it is
possible to create action lists which execute a sequence of commands on the reader. This list can then be
linked to various inputs.
Figure 40 GPIO
The GPIO tab is divided into 3 sections, IO Configuration, consisting of Input and Output, Test Input and Test
Output, Action List and Assign Input to Action List which are described in the following chapters.

ᬅ
Invert logical
input
negates the electrical input signal and uses this state for processing in the reader;
if the parameter is not checked, the signal is used
ᬆ
Debounce
time
assigns a debounce time in milliseconds to each channel depending on the sensor
being used (mechanical or electrical switch)
