Configuring General Purpose Input/Output
When needed, port #1 can be used as an input to remotely switch the RF Field on and off. This is
useful to limit the HF field generation to a strict minimum, i.e. whenever a person is about to enter
the detection passageway crossing a light barrier placed ahead of the pedestal and keep it on for a
fixed duration or whenever the person is exiting the RFID detection area using a second light
barrier beam crossing detector.

Refer to Figure 22 for the pin layout to wire the Input and output signals.
In section GPIO#1, select one of the available options:
•
GPIO: Port has no predefined function; it can be driven remotely by Host PC via API.
•
Input Trigger: when wired signal matches the Active Level Setting (“Low” or “High”) the
Radio Frequency Field will be turned On, Theft detection becoming active.

•
Output Trigger: when Theft is detected (EAS or AFI signal setting the alarm), the Port
Signal level matches the Active Level Setting (“Low” or “High”). The output voltage level of
the port should match the active voltage to set the external alarm device wired up.

In section GPIO#2, select one of the available options:
Once you have set the basic configuration, check that all the slaves are
well synchronized. To do so, L-SP3 electronics unit green LEDs should
flicker cyclically. If not, proceed to the advanced configuration stage.
