The highest value of the day was already achieved at
the time of the last measurement before the day change
(no new pulses between the time of the last
measurement and day change)
The highest value of the day is recorded at the time of
the first measurement after the day change (new pulses
between the time of the last measurement and day
change)
6.3 ALOHA transmission mode
ALOHA transmission mode is a special connection mode whereby the myDatalog2Ex establishes a
connection to the myDatanet server for a period of time configured via the "Basic settings"
configuration section (see "Aloha/wakeup duration" in chapter "Basic setting" on page 80).
Note: ALOHA transmission mode cannot be activated if the myDatalog2Ex is connected to
the USB interface of a PC.
InitiatingALOHAtransmission mode:
l
Directly on the device using the solenoid switch (see "Solenoid switch" on page 65). The GSM
network is re-selected during this process. This means that a list of all of the GSM networks in
the receiving range of the device is created from which the first GSM network is then selected
that is not on the "Ban list" (see "Ban list" on page 37) and that is part of one of the service
providers supported by the integrated SIM chip or the external SIM card (see
www.microtronics.at/footprint).
A speech bubble in the measurement instrument list (see "myDatanet Server Manual " 805002)
with the title "Aloha" indicates that a device is in ALOHA transmission mode.
Clicking on the speech bubble with the "Aloha" title opens the ALOHA data window (see
"myDatanet Server Manual " 805002). It contains the internal "Battery" and "GSM level"
measurement values, as well as the measurement values of the 2 universal inputs. The
