Operating the Reader Using the ReaderStart Software

GPIO Functions
Readers with GPIO functionality
1)
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.

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.

①
Invert logical
input
negates the electrical input signal and uses this state for processing in the reader; if the param-
eter is not checked, the signal is used
②
Debounce
time
assigns a debounce time in milliseconds to each channel depending on the sensor being used
(mechanical or electrical switch)
③
Invert logical
output
negates the electrical output signal
④
Function
selects between the functions described in
⑤
First antenna
the first antenna for the selected function
