Manual Datafox ZK-MasterIV
Now the ZK-MasterIV sets its internal clock on 17:00:55 and the date on 28 Oct 2003.
If connection problems occur, the error analysis can be simplified with the help of an alive-data record.
Via the alive- data record you can detect if the device was on- or off-line, e.g. at the moment of power
outage. You also can detect if the web-server was reachable all the time with the aid of the alive-counter in
the alive-data record. With each failed attempt to send data the alive-counter increases. If no data reach
the server and the alive-counter in the alive-data record has the value 1, the device has been removed
from the power supply.
Figure 32: Activation of the alive-data record
Note:
£ After three failed attempts to send data, the ZK-MasterIV starts the device regen-
eration with a timeout of 15 minutes. When the timeout is run out three attempts
to send the data are started again. Thus, the generation of unnecessary costs is
prevented.
Caution:
Alive data are temporary data. If the alive-data record cannot be sent (e.g. server is
nor reachable), it will be deleted and the alive-counter will be increased by one. The
function "'alive"' is activated via the alive parameter in the GPRS.ini. Additionally
to the activation the F6-chain or (from version 04.01.04.x on) or the GPRS-chain
has to be available in the signal processing. Take care that this function does not
create unintentional data (trafic).
Version: 04.01.07.00
Activation of the function Alive via the parameter
"'Alive"' (cycle for the creation of the alive-data
record in seconds) with a value higher than 60 and
lower than 65500.
The data fields of the alive-data record you should
define in any case are the device number, date and
time and the alive-counter.
The value of the alive-counter * cycle for the
creation = duration of interference.
formula you can calculate the duration of interfer-
ence via the alive-counter.
