Chapter 5 – Components and Operation
Programming will be initiated by a rising edge of the PROG bit; i.e. first the transpon
-
der code which has to be programmed with PROG=0 should be transferred, subse
-
quently the same transponder code wit PROG=2. Thus the released programming
process lasts approx. 100 ms. Afterwards the new code will be read directly and is
available for the input bytes.
5.2.7 Software download
If necessary, the antennas may be updated via the serial interface. Please refer to
chapter 6.3 „Software Update (Antenna Software)“ auf Seite 36.

(refer to section 6.2.2.3 on
page 32). The Baud rate must be set to 19200 Baud.
Out of this data stream the
code
is converted into a 16 Bit parallel output. The code
then contacts the outlets until the next code is received. In addition, 10 ms after the
code bits are applied a data ready pulse of 100 ms is generated as the antenna pass
-
es over a transponder, i. e. the same transponder generates a new data ready pulse
as it enters the field again (e. g. when switching tracks).
The validity of the voltage, i. e. if a transponder is actually within reception range, is
displayed by the signal
Data_Valid
. If there is no transponder within the range,
0 V is output. The parallel outputs,
Data_Ready
and
Data_Valid
are switched
contra

and are not current limited. In addition they are not potentially
separated.
