If multiple text messages have been received, pushing this button will display the last 5.
Signal Quality
Displays the last measured cell signal strength in terms of bars, or in dBm with % bit
error rate. The dBm value can range from -51 (strong) to -113 (weak). For reference -75
is considered “5 bars”, and -105 is considered “2 bars”. The bit error rate will vary from
0.2% (best) to 12.8% (worst). Often the bit error rate is a better indicator of quality than
signal strength.
Update
Pressing the Update button will cause the signal strength to update for 2 minutes or until
the button is pressed again. As it updates, a tone is output by the Xpert that’s proportional
to the signal strength. The higher in frequency, the better the signal. This can be used to
aid in aiming the antenna.
ON
Pressing “ON” turns the GPRS radio on until the next scheduled off time.
OFF
Pressing “OFF” turns the GPRS radio off until the next scheduled on time. GPRS will
still turn on as needed for transmissions.
Selftimed statisitics…
Displays the following information about self timed transmissions:
Last Tx, #Tx Today, Next Tx Time, Next Tx msg, Next Tx size, Est #Tx bytes/day, and
#Tx bytes today.
The estimate #Tx bytes/day can be used to help estimate the data budget for a station, but
as it doesn’t include overhead it will be significantly low.
Alarm statistics:
Displays the following information about alarm transmissions:
Last Tx, #Tx today, #Tx bytes today.
GPRS Test Dialog
The GPRS Test Dialog is used to send test transmissions using SMS, Selftimed, or SSP
messaging. Select the type of transmission, enter a test message (and other related
information), and press Send.
