5.1 ALOHA transmission mode
ALOHA transmission mode is a special connection mode whereby the NivuLog Easy creates a connection to
the Device to Web server for a period of time configured using the "Basic settings" configuration section (see
"Aloha/wake-up duration" in chapter "Basic settings" on page 58).
There are two options for initiating the ALOHA transmission mode:
l
Directly on the device by means of the solenoid switch (see "Solenoid switch" on page 37) or button
(see "Buttons" on page 36).
l
Via the Device to Web sever if the "Interval & Wakeup" connection type has been selected (see "Basic
settings" on page 58).
A speech bubble in the measurement device list (see "Device to Web Server Manual " - upon request) 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 "Device to Web
Server Manual " - upon request). It includes the internal "voltage", "GSM level" and "battery" measurement
values, as well as the measurement values of the 4 universal inputs. The measurement values for the last
thirty minutes are always shown in the ALOHA data window, this can mean that data from a previous ALOHA
transmission is included. The ALOHA data is generated every three seconds independently of the normal
measurement values that are generated and is thus not saved with the standard measurement data.
If a measurement dataset is recorded during ALOHA transmission mode, it is immediately transmitted to the
Device to Web server and saved in the standard measurement data.
