Components Description
Power LED If the correct voltage is applied to the device, the
Power LED is green and the device is operational.
Reset button Pressing this button initiates a power-reset of the
device. The reset button must be pressed for at least
three seconds until all the LEDs of the foil keypad
simultaneously start and the hardware reset is
executed.
Mode button If the mode button and the reset button are
simultaneously pressed at a powerup reset for about
15 seconds until all the LEDs of the keypad light up for
the second time, the reader will be reset to the default
state (default factory setting).
Mode LED Currently no use.
Test button Pressing this button switches the device to the reading
test mode and is used to select the antenna ports. If
the button is pressed for a longer time (at least 2
seconds), then the test mode is activated (Test OK LED
and Test Error LED both briefly come on) or disabled
(Test OK LED and Test Error LED both go out). Briefly
pressing the buttons when the test mode is activated
results in switching to the next antenna port.
Test OK LED When a transponder in the test mode can be
successfully identified, this LED turns green.

I/O ports 1 to 4 A digital input and output can be connected to each
antenna port. A 3 wire sensor or dry contact is possible
as the input. The output can operate a LED without a
series resistor or directly switch 5 V DC
(Imax = 100 mA).
