The last known state of the probe is displayed in brackets for each parameter. The parameters should be
set as explained below:
General Tab
Parameter Comment
TETRA Type Set to ‘Motorola’ or ‘Sepura’ depending on the terminal type
Packets Accumulate
Period
Enter the time in minutes that the probe should wait
between sending data back to the server. Setting this
parameter to 0 means that data is sent back instantly so
that the server shows data in real-time. Increasing this
parameter to maybe 10 or 20 minutes will cause the probe
to accumulate logged data and then send it all in one go to
the server. The advantage of this is that the overall amount
of data sent using GPRS is reduced as there is a significant
overhead per data transmission hence GPRS costs are
reduced – at the cost of the server being slightly behind
real-time.
Use Encryption Data from the probe to the probe to the server may be sent
in clear text or encrypted using the DES64 algorithm. There
is no significant time or data amount penalty using
encryption therefore this is the default.
Handover Timeout This is the timeout period in secs after a handover event. If
another handover or ‘No Service’ event occurs in this period
then the initial handover will be marked as a Failed
Handover.
Collect Neighbour Info Specify how often the full neighbour list should be logged.
As this produces a large amount of data the default is ‘On
Handover and every 10 events’
Action when external
power removed
Options are ‘Continue running on battery’ or ‘shut down
after 15 mins’. If the TETRA radio is also powered down
then the probe shall send Tracking messages (if allowed in
the Monitor Tab). If there is still data in the probe internal
memory to send to the server then the probe shall continue
to remain operational until the data has been sent or the
battery runs out.
Network Tab
Net APN As specified by the GSM provider
e.g. for Orange UK set to ‘orangeinternet’
Net Username As specified by the GSM provider
e.g. for Orange UK set to ‘user’
Net Password As specified by the GSM provider
e.g. for Orange UK set to ‘pass’
Monitor Tab
TETRA Params Rate Enter the time in seconds between each monitor message
– default is 60, minimum is 5. When using very short
monitor periods, i.e. less than 60secs, it is generally a good
idea to set a Packets Accumulate Period of 1 min to prevent
too many simultaneous attempts to send individual
messages to the server.
Enable Tracking Send Tracking messages when the probe is running but
there is no TETRA radio attached or powered up.
Call Tab
Enable Active TETRA
operations
Ticking this enables the probes to make test calls
Test Call Type Options are:
‘PTT Only – No Speech’
‘One Sample in each direction’ – VQ test call
‘Two samples in each direction’ – VQ test call
