usage is similar to what it would be if you had selected this
rate for the normal logging interval.
Setting a Password
You can create an encrypted password for the logger that is
required if another device attempts to connect to it. This is
recommended to ensure that a deployed logger is not
mistakenly stopped or purposely altered by others. This
password uses a proprietary encryption algorithm that changes
with every connection.
To set a password:
1.
Tap Devices. Press the button
on the logger
to wake it up, if
necessary. Tap the logger tile in the app to connect to it.
2.
Tap Lock Logger.
3.
Type a password and then tap Set.
Only the device used to set the password can then connect to
the logger without entering a password; all other devices are
required to enter the password. For example, if you set the
password for the logger with your tablet and then try to
connect to the logger later with your phone, you must enter
the password on the phone but not with your tablet. Similarly,
if others attempt to connect to the logger with different
devices, they are also required to enter the password. To reset
a password, press the button on the logger for 10 seconds or
connect to the logger and tap Manage Password and tap Reset.
Downloading Data From the Logger
To download data from the logger:
1.
Tap Devices. Press the circle button
on the logger
to wake it
up, if necessary. Tap the logger tile in the app to connect to
it.
2.
Tap Download Data. The logger downloads data to the
phone, tablet, or computer.
3.
Once the download is complete tap Done to return to the
previous page or tap Export and Share to save the file in the
specified format.
4.
When the export file has successfully been created, tap
Done to return to the previous page or tap Share to use
your device’s usual modes of sharing.
You can also upload data automatically to HOBOlink, Onset’s
web-based software, using the app or the MX gateway. For
details, see the HOBOconnect User Guide and see the HOBOlink
help for details on working with data in HOBOlink.

Deploying and Mounting the Logger
When mounting the logger, it is very important that the logger
housing does not get distorted. If you are mounting the logger
on an irregular surface, it is recommended that you use the
mounting boot (BOOT-MX2201-2202).
•
The logger must be mounted to a flat surface or in such a
way that prevents the logger housing from bowing. You
can deploy the logger by using the two mounting tabs.
Insert two screws through the round holes on the
mounting tabs to affix the logger to a flat surface, being
careful not to overtighten the screws. Alternatively, you
can hang the logger using a loose cable tie loop.
Guidelines for Using the Mounting Boot
•
To install the logger in a boot, hold both the boot and the
logger upside down and insert the logger mounting tab
into the boot as shown.
Use screws with
the round holes
