Further menus are activated via input of the (characters in brackets). Before altered
values are transferred into the permanent memory, the pass word
815
has to be en-
tered
by first entering
. This prevents unwanted alterations of values. With
the val-
ues are saved after alteration and input of the password.
Input of
enables reading the description of a possibly occurring system status mes-
sage. If the procedure is „transparent or „3964r“ input of
will exit this menu.
The following section describes the submenus

CA(

Frx [Hz]
and
Ftx [Hz]
Display of important system frequencies for transmission and
reception. These frequencies are permanently monitored and
are included in the system status word E (see below)
CSEL
Determins from which channel the code is detected
U [mV]
Supply voltage of the processor board measured with an accu-
racy of 100 mV. This voltage is, due to various safety measures,
always a little lower than the connected overall supply voltage
I [mA]
Current consumption of the positioning unit measured with an
accuracy of 10 mA
T [Grd.C]
Average temperature measured in steps of 5
o
C
S_MA
Hexadecimal system status from master. The description of the
individual bits is included in Table 4 „List of the system com-
mands“ on page 22
S_SL
Hexadecimal system status from slave.
Noise
Output of one counter:
-
Whenever the sum voltage S exceeds the
Threshold for
Decoding
the counter is increase every 8 ms until it has
reached the value 1.000.
-
Whenever S falls under this threshold, the counter counts
backwards until it has reached 0 again. When a code is
decoded, the counter is immediately set to 0.
This mechanism checks whether a Transponder or a foreign sig-
nal is received. Every time this counter exceed an adjustable
value (refer to section 5.3.2.3 „(T)ime & Code“ on page 37), the
system status bit RX_NOISE is set.
