through the mounting pole and brought out at or near
the bottom so that the wires can be connected to the
sensors. DO NOT connect the sensors yet. Be sure to
have the cable exit the pole above the level of the inner
post to avoid wire damage. Also leave an adequate
length of cable exposed to allow the pole to be lifted off
of the inner post without disconnecting from the sensor
wires. The use of a small valve box or junction box will
protect the wire splices and make them easy to find
should anything need to be disconnected in the future.
Node cases are rainproof but should always be
mounted vertically. The components inside the cases
are conformal coated for moisture protection but
should not be directly exposed to water.
Use the form on page 10 to record ID numbers,
located on the label under each Node’s clear cover,
and a reference name for its location. This information
will be needed later when you configure your system in
the WEB portal or WaterGraph Software. Note that
these numbers are comprised of only 0 through 9 and
letters A through F. Be sure to record them accurately.
The geographic reference (latitude/longitude in
decimal degree format) for each Node can be input
during set-up to enable Nodes to display in the portal’s
mapping feature (when using SensMitWeb).
Off-Season Shut-Down: To properly shut a system
down during the off-season, slide the power switch
inside the Base housing to ‘OFF’ and cover the solar
panels. It is best to remove the Base from the field
entirely. If the Base is left operational during non-
reporting periods, it will still accumulate data then upload
it once connectivity is re-established next season,
possibly incurring additional data usage charges.
SENSORS: Once all Nodes are in place and the
network is functioning properly, the sensors can be
installed and wired to the Nodes. Refer to the
‘Connecting to WATERMARK Sensors’ section on
page 6, and the color reference wiring instructions on
page 9. When in place, configure them to display
using your own alphanumeric descriptive references.
Data Collection Options
LOGGER — 975L
Data is collected from the Base by a stationary
Logger in the field and retrieved manually
with a laptop computer. A free download
of 975L WaterGraph Software is provided
to retrieve, view and graph data.
NOTE: The Logger is used to batch
download data but cannot be used to
‘stream’ data.
Charging and Associating the Logger: The Logger is
powered by internal super capacitors that are charged
in full sunlight (just like the Base). Slide the power
switch inside the enclosure to the ‘ON’ position, remove
the black bag that covers the solar panels and include
the Logger when charging and associating the Base
and Nodes as described on page 2.
Installation of the Logger: The Logger must be
mounted in the field with fully charged capacitors and its
power switch in the ‘ON’ position within 400’ (122 m) of
the Base, though it is usually mounted on the same
pole. Mount the Logger, like the Base, on any sturdy
post or pole using supplied mounting brackets, as
described on page 3. (
Installation – Base).
Data Collection with a Logger: 975L software
available from the IRROMETER website at
www.IRROMETER.com/download/975-DL.exe
and running on a Windows
®
OS laptop is necessary for
data download and display. The Logger must be fully
charged and associated before connecting to the
computer with the 975L software for the first time. The
saved data file can then be opened for display with the
graphing program included in the 975L software or
uploaded to SensMitWeb for later access, archiving
and sharing if a subscription is purchased. (See the
‘IRROmesh Logger User Manual’ that accompanies
each Logger purchase, for detailed Logger instructions.)
Off-Season Shut-Down of the Logger: Slide the power
switch inside the housing to ‘OFF’ and cover the solar
panels. Remove the Logger from the field (optional).
PC LINK — 975P
Data is automatically and continuously ‘streamed’ to
the WEB using your computer’s active Internet
connection as long as the computer is on and running
the SenMitPath software. The PC Link connects to your
computer via USB cable and is required to be within
400' (122 m) of the Base. (Range is dependent on what
type of structure the signal transmits through.) Data is
viewed and stored on the WEB. (Subscription required)
Charging and Associating the PC Link: The PC Link
must be plugged in to an active computer or any USB
socketed power source to supply its power. Once fully
charged, it will hold the charge long enough to be
