Adding the Mote to the RX Wireless Sensor
Network
The mote must join an RX Wireless Sensor Network before it
can begin transmitting data. This requires accessing the RX3000
Station and the mote at the same time so it is recommended
that you complete these steps before deploying the mote.
Important: If you have not configured the RX3000 Station with
the RXW Manager, follow the instructions in the RX3000 Quick
Start before continuing.
To add a mote to the RX Wireless Sensor Network:
1. If the LCD is blank on the RX3000 station, press any button
to wake it up.
2. Press the Select button once (which shows the number of
smart sensors installed) and then press it again once if the
HOBO RXW Manager is installed in the left slot (module 1)
or twice if it is installed on the right slot (module 2).
3. Press the Search button (the magnifying glass). The
magnifying glass icon will blink while the RX3000 is in search
mode.
4. Open the mote door and install the batteries if you have not
already done so.
5. Press the button on the mote for 3 seconds. The signal
strength icon will flash and then cycle.
6. Watch the LCD on the mote. The signal strength icon and
the LEDs will quickly blink while the mote searches for the
wireless network. Once it has found the network, the icon
will stop blinking and the signal strength bars will slowly
cycle from left to right. As the mote completes its
registration process with the network, the “x” icon to the
right of the signal strength icon will flash and the yellow-
green LED will stop blinking. Once the registration is
complete, the signal strength bars will stop cycling and
remain solid and the channel count on the RX3000 LCD will
be updated by 1 to represent the battery channel in the
mote. This process may take up to five minutes.
7. Press the Search button (the magnifying glass) on the
RX3000 Station to stop searching for motes.
Use HOBOlink to monitor mote status. See the HOBOlink Help
for details on how to check mote status, add the mote to a
map, and more.
Deployment and Mounting
• Use cable ties to mount the mote via the holes on the
mounting tabs.
• Avoid mounting the mote near metal, which can cause
interference with the signal.
• Position the mote towards the sun, making sure the solar
panel is oriented so that it receives optimal sunlight
throughout each season. It may be necessary to
periodically adjust the mote position as the path of the
sunlight changes throughout the year or if tree and leaf
growth alters the amount of sunlight reaching the solar
panel.
• Make sure the mote door is closed, with both latches fully
locked to ensure a watertight seal.
• Consider using a 3/16 inch padlock to restrict access to the
mote. With the mote door closed, hook a padlock through
the eyelet on the right side of the door and lock it.
• To maximize the communication between motes, place
the mote within 304.8–457.2 m (1,000–1,500 feet) and full
line of sight with the next mote in the network and at least
1.8 m (6 feet) from the ground.
• If there is an obstruction between two sensor motes or
between the sensor mote and the RXW Manager, then use
an RXW Repeater (RXW-RPTR-xxx) mounted higher than
the two motes. For example, if there is a hill or mountain
between the sensor mote and the RXW Manager, place a
repeater at the top of the hill between the sensor mote
and the RXW Manager.
• There should not be more than five motes in any direction
from a repeater or the RXW Manager. Data logged by a
wireless sensor must travel or “hop” across the wireless
network from one mote to the next until it ultimately

reaches the RXW Manager at the RX3000 station. To make
sure the data can successfully travel across the network,
the sensor mote should not be more than five hops away
from a repeater or manager.
• The RX Wireless Sensor Network can support a maximum
of 50 motes.
• Use a #4-40 screw to attach a ground wire to the port on
the back of the mote if you are deploying the mote in a
location where lightning is a concern.
• Make sure the mote remains in a vertical position once it
is placed in its deployment location for optimal network
communications.
• Follow the instructions in the smart sensor manual for
how to deploy the sensor.
Maintenance
The mote and smart sensor case are designed for outdoor use,
but should be inspected periodically. When inspecting them, do
the following:
• Verify the mote and smart sensor case are free of visible
damage or cracks.
• Make sure the mote and smart sensor case are clean.
Wipe off any dust or grime with a damp cloth.
• Wipe off any water before opening the mote or the smart
sensor case.
• Make sure the interior seal is intact and the latches are
fully locked when the mote door is closed.
• Make sure the rubber cable channel is free of cracks and
all holes are filled with either cables or rubber plugs.
Updating Mote Firmware
If a new firmware version is available for the mote, use
HOBOlink to download the file to your computer. Connect the
mote to the computer with a USB cable (open the mote door
and use the USB port to the right of the LCD). The mote appears
as a new storage device in the computer’s file storage manager.
Copy the downloaded firmware file to the new storage device
(the mote). After the file is copied, eject the storage device
from the computer and disconnect the cable from the mote.
The file will be installed automatically on the mote. Note to
Mac® users: A message may appear indicating the disk has not
ejected properly. The mote is operational and you can ignore
the message.
Battery Information
The mote uses two 1.2 V rechargeable NiMH batteries, charged
by the built-in solar panel. The quality and quantity of solar
light can affect whether the battery is sufficiently charged to
last through the night and cloudy periods. Make sure the mote
is placed in a location that will receive several hours of sunlight
each day. If the mote does not receive enough sunlight to
recharge the batteries, the battery life is estimated at 3–4
months. When batteries are regularly recharged, expected
battery life is estimated at 3–5 years. Battery life varies based
on the ambient temperature where the mote is deployed, the
logging interval, the number of tripped alarms, and other
factors. Deployments in extremely cold or hot temperatures
can impact battery life. Estimates are not guaranteed due to
uncertainties in initial battery conditions and operating
environment.
Mote operation will stop when battery voltage drops to 1.8 V.
Mote operation will return if the battery recharges to 2.3 V. If
the batteries are unable to be recharged, replace them with
fresh rechargeable batteries.
To replace rechargeable batteries:
1. Open the mote door.
2. Remove the old batteries and install the new ones
observing polarity.
3. Make sure the solar panel cable is plugged in.
You can use two 1.5 V lithium batteries (HWSB-LI) for operation
at the extreme ends of the mote operating range. Lithium
battery life is an estimated at 1 year, but varies based on the
ambient temperature where the mote is deployed, the logging
interval, the number of tripped alarms, and other factors.
Estimates are not guaranteed due to uncertainties in initial
battery conditions and operating environment. When using
lithium batteries, you must disconnect the solar panel cable
because the batteries will not be recharged.
To install lithium batteries:
1. Open the mote door.
2. Remove any old batteries and install the new ones
observing polarity.
3. Push in the side tab of the solar panel cable connector and
pull the connector out of the cable port.
4. Place the connector in the slot on the inside of the mote
door. Make sure the solar panel cables are tucked inside the
door so that they do not interfere with the interior seal
when the mote is closed.
