Connecting the Logger to a Computer
The HOBO Pendant logger requires either of the following to
connect to the computer:
•
Pendant Optic USB Base Station & Coupler (BASE-U-1);
HOBOware 2.1 or later
OR
•
Optic USB Base Station (BASE-U-4) or HOBO Waterproof
Shuttle (U-DTW-1); coupler (COUPLER2A); HOBOware 2.2 or
later
If possible, avoid connecting at temperatures below 0°C (32°F)
or above 50°C (122°F).
1. Plug the USB connector on the base station into an available
USB port on your computer.
2. Insert the logger and the base station into the coupler, as
shown in the following diagrams.
For BASE-U-1, make sure that the logger is inserted in the
end of the coupler that has the magnet, and that the ridges
on the base station and logger are aligned with the grooves
in the coupler.
For BASE-U-4 or the HOBO Waterproof Shuttle, firmly insert
the optical end of the base station into the D-shaped end of
the coupler, and make sure that the ridge on the logger is
aligned with the groove in the coupler.
3. If you are using the HOBO Waterproof Shuttle, briefly press
the coupler lever to put the shuttle into base station mode.
4. If the logger has never been connected to the computer
before, it may take a few seconds for the new hardware to
be detected.
5. Use the logger software to set up the alarms, launch, and
read out the logger.
You can read out the logger or check its status while it
continues to log, stop it manually with the software, or let it
record data until the memory is full. Refer to the software
user’s guide for complete details on launching, reading out, and
viewing data from the logger.
Important:
Do not cover the optical communication window in
the logger (shown in diagram above) with a label or sticker as
that may interfere with the communications with the base
station or shuttle.
Connecting to a Tipping-Bucket Rain Gauge
The logger’s black and white input wires can be connected
directly to the relay output of most tipping-bucket rain gauges.
(Polarity of the input connection is not important.) If your
gauge came with a counter display and battery, disconnect
