I/O 1: Trigger (input)
I/O 2: Copy of trigger (output)
I/O 3: Active when tag is correctly read (output)
I/O 4: Active when no tag has been read after a trigger (output)
The trigger function operates based on the voltage level; i.e. active high or active low. The IDs of
tags detected when the trigger is active can either be sent immediately or after the trigger is reset
(inactive). If no tags are detected during a valid trigger condition, a specific character string can be
sent. This character string is called a "No Read" message and can be defined by the user. This
string replaces the tag ID field in the tag message frame.

The output duration of I/Os 3 and 4 can be individually set for a time between 0 and 63750
milliseconds in steps of 250 milliseconds. These outputs are generally used in connection with a
signal box.

8.2.6 Watchdog
A Watchdog function is available. A specific user-defined ASCII message can be regularly sent.
The Repetition Delay can be set up to 63750 milliseconds in steps of 250 milliseconds.
In Trigger mode, the antenna RF field is switched on only when the trigger is activated.
