Component
Description
LF module
Via the antenna the LF module supplies the
transponder with energy and it transmits the
received data to the controller.
Tuning LEDs
The six Tuning LEDs show the switch status of
the adjustment relays.
RS232 interface
The data are passed down serially to one of the
two
RS232 interfaces
(9-pin Sub-D female
plug) with the different protocols. Baud rates of
300 Bd up to 115.2 kBd are possible.
Ethernet interface
Communication with the device can be carried
out via the 10/100 BaseT Ethernet interface
(IEEE 802.3) with PoE.
External output
The external output (usually a LED) shows the
status of the reader. The behavior of the
external output is depending on the sensor
triggered automatic reading.
The LED remains on until the read operation is
complete. The LED goes off if the reader
receives confirmation that the page was read, or
if an error message occurs.
If the host does not return confirmation after the
page was read, the LED remains on until either a
new read process is started and successfully
completed, or until the device is reset.
External input
A sensor (such as an optical sensor) can be
connected to the external input.
Fuse
TR5 housing, 400 mA T (low-breaking).
Tuning LED
The antenna's efficiency is optimized by pushing
the automatic calibration button. The LED lights
up during the calibration process and
subsequently goes off when tuning is successful.
If a fault occurs, the LED flashes until the next
calibration process is successful.
Possible faults could be caused by a defective
antenna or a strong metallic environment near
the antenna.
Antenna LED
If the antenna sends LF signals (to load a
transponder or send data, for example), the LED
is activated for this period.
