sensors (logging interval and sampling interval) and the settings
for each smart sensor (labels, graphs, and scaling).
a. Click Smart Sensors Logging from the menu on the left.
b. Select the logging interval. This will be used by all
configured smart sensors.
c. Enable the sampling interval and enter the rate to use in
minutes and seconds.
Tip: When a sampling interval is configured, the station
will take multiple measurements within a given logging
interval and then average them together to create a
single logged data point. This is only an option for the
following smart sensors that support measurement
averaging: temperature (S-TMB-M0xx), PAR (S-LIA-
M003), solar radiation (S-LIB-M003), barometric
pressure (S-BPA-CM10 and S-BPB-CM50), 4-20mA input
(S-CIA-CM14), 12-bit voltage input (S-VIA-CM14), and
FlexSmart TRMS module (S-FS-TRMSA-D). Disable the
sampling interval if none of your smart sensors support
measurement averaging to avoid unnecessary drain on
the battery power.

Offset, and Scaled Measurement Type fields.
h. Click Save. You can also click Next to move from one
smart sensor to the next.
i. Repeat steps e–h for any additional smart sensors you
need to configure.
Analog Module and Sensor Configuration
You can configure both the global settings for the analog
module that affect all connected analog sensors (logging
interval, statistics, and excitation) and the settings for each
individual analog sensor (enabled logging and graphs,
labels, sensor type, and scaling).
a. Click Module <#>: Analog Sensors Logging from the
menu on the left.
b. Select the logging interval to be used for all analog
sensors, which can be different than the one used for
smart sensors (if applicable).
c. Click the Enable checkbox under Sampling Interval if you
want to log statistics. Enter the sampling interval to be
used for calculating the statistics (must be a factor of
the logging interval). Select the statistics to be logged:
minimum, maximum, average, and standard deviation.
The selected statistics will be calculated between each
logging interval at the sampling interval rate you select.
Each statistical value will then be logged at each logging
interval.
d. Enable “Use excitation power” if you want sensors to
use the 12 V DC excitation voltage provided by the
station. Select warmup and enter the seconds or
milliseconds (5 milliseconds to 120 seconds), or select
continuous. Note that the excitation power selected will
be used for all of the module’s configured sensors.
•With warmup, the station supplies excitation power,
12 V DC, for a brief period prior to each
measurement. This allows you to select the minimum
warm-up time needed to allow for sensor
stabilization while conserving battery power. For
example, if you specify a warm-up of one second and
set the logging interval for the module to one minute,
the station will power the external sensor for one
second, log a measurement, and then turn off the
excitation power for the next 59 seconds. Note that
the excitation mode is automatically set to
Continuous if the warmup time selected is within one
second of or greater than the logging or sampling
intervals.
•With continuous, the station supplies constant
excitation power to the sensor for the entire duration
of the deployment. Continuous mode is required if the
sensor needs more than two minutes of warm-up time.
Important: Continuous mode operation will greatly affect
battery operating life and is not recommended.
Note that excitation power will not be enabled until
logging begins (if “Logging” is blinking on the LCD, then
excitation is not being used).
e. Click Save. You can also click Next to move from one
analog channel to the next.
f. Click one of the four analog sensor channels from the
menu, such as Channel 1 shown in this example.
g. Select “Enable Graph” if you want the sensor data to be
graphed in HOBOlink.
h. Select “Enable this channel” if you want the station to
record data for this channel. If the channel is not
enabled, then it will not be part of the channel count
shown on the LCD.
i. Type a label for the sensor (optional).
j. Select the sensor/input type, which is needed to set the
voltage or current range for the analog input.
k. Click the Enable Scaling checkbox and then enter the raw
and scaled unit values as defined in the sensor manual.
Type the scaled measurement type.
l. Click Save. You can also click Next to move from one
channel to the next.
m. Repeat steps f–l for any additional analog sensors you
need to configure for the module.

Note that any existing alarms associated with removed
modules will be listed in HOBOlink. See the HOBOlink Help for
details on deleting alarms. Also, if you are using alarms to
activate relays, check that the relays are in the proper state.
Managing Connections to HOBOlink
The station will connect to HOBOlink on the connection interval
you selected in Readout Configuration.
To change the connection schedule:
1. Click the arrow next to on the Devices page or next to
Configure button at the top of your station’s page and
select Readout Configuration.
2. Set the connection interval. For the RX3003 cellular model,
the minimum connection interval depends on your
communication plan.
3. If you wish to set up a second connection interval, select
the “Night Mode” checkbox. Select when night mode
should begin and end and then enter the connection
interval you want to use during that part of the day.
4. Click Save. The changes to the connection interval will take
place the next time the station connects to HOBOlink.
You can also connect to HOBOlink from the station at any time,
regardless of the connection schedule. Press the Connect
button on the station to connect to HOBOlink. Unless the
station is running on a night mode connection interval, the
normal connection schedule will then restart after the
connection is complete. For example, a station is configured to
connect hourly and the last connection on its regular schedule
occurred at 10:05. If you use the Connect button on the station
to connect to HOBOlink at 10:15, the next connection will then
be about 11:15 based on the one-hour connection interval.
Similarly, if a station misses a connection, the connection
schedule will shift depending on the time of the next successful
connection. While the station is using a second, night mode
schedule, all connections will follow that schedule only; any
extra connections while the station is in night mode will not
cause a shift in the connection schedule.
Also note that the station will connect to HOBOlink when the
device is powered up and when you press the Start button.
For RX3003 cellular models: All connections to HOBOlink count
toward your communications plan. If the station is nearing its
limit for monthly cell use, minimize unscheduled connections.
This includes any connections for alarms or changes you make
to the connection schedule. You can also increase the
connection interval to reduce the number of connections to
HOBOlink per day. Check the Device Information section on
your station page in HOBOlink to check the status of the
monthly communications plan usage for the station.
Checking Latest Conditions with HOBOware

Deploying and Mounting the Station
Follow the guidelines and steps in this section for deploying and
mounting the station.
Deployment Guidelines
When deploying the station:
•Check the signal strength on the LCD in the location you
wish to deploy the station to make sure it will be able to
reliably connect to HOBOlink (RX3002 Wi-Fi and RX3003
cellular models). The station may have difficulty
connecting if there is only one bar illuminated in the Wi-Fi
or cellular LCD symbol. (The signal strength shown on the
LCD is from the last connection.)
•The RX3003 cellular model must be mounted at least one
foot from all sensors to avoid interference from the built-
in radio module and antenna with the measurements
made by the sensors.
•Make sure the station remains in a vertical position once it
is placed in its deployment location. If it is mounted
horizontally, the battery could be damaged over time as it
is charged and the antenna (if applicable) will not have
optimal range.
•If you haven’t already done so, plug in an AC adapter, solar
panel, or other external power source to keep the battery
charged.
•If you are using a wind speed/direction sensor or if the
station will be installed on a roof or in a location with
exposure to lightning, use the grounding wire included
with this station and ground the tripod or mast using
appropriate grounding, such as the Grounding Kit (M-
GKA). A grounding wire may also reduce potential sensor
errors that can result from installing near other radio or

HOBO RX3000 Remote Monitoring Station Manual
1-800-LOGGERS 15 www.onsetcomp.com
electrical equipment or antennas. See Installing the
Grounding Wire.
•Make sure all cables and wires are fastened securely,
routed through the cable access openings, and placed in
the rubber cable channels. Any empty holes in the cable
channels need to be filled with the appropriate size plug to
ensure the station is weatherproof. See Installing the
Weatherproof Rubber Cable Channel and Covers.
•Do not store excess sensor cable wire coiled inside the
station case or within one foot outside the case.
•Protect cables and wires with conduit. Exposed cables can
be chewed by rodents.
•Make sure the total cable length for all installed smart
sensors does not exceed 100 m (328 ft).
•Consider using a padlock to restrict access to the station.
With the station door closed, hook a padlock through one
of the latches on the right side of the door and lock it.
Installing the Grounding Wire
Insert the grounding wire through the larger of the two cable
access openings and plug it into the ground connector. You may
need pliers to connect it to the station. The grounding wire
must be connected to a properly grounded mast (typically on
one side of the U-bolt) when the station is mounted.
Mounting the Station
Attach the mounting plates with a Phillips-head screwdriver to
the back of the station to mount it on a flat surface. Mount the
station vertically to a wall or board using screws.
You can also mount the station vertically to a mast or pole and
tripod using U-bolts (unscrew the nut on the U-bolt to place
around the mast or pole). Screw the mounting plates to the
back of the station as shown above. Make sure the mounting
plates are mounted against the flat part of the U-bolt saddle
clamps. If using the grounding wire, attach it to one end of the
U-bolt. Refer to the Tripod Setup Guide for full details.
Installing the Weatherproof Rubber Cable
Channel and Covers
Important: This is required for outdoor and weatherproof
deployments and recommended for harsh indoor environments
where debris could enter the station.
1. Make sure all sensors and cables are installed, including the
solar panel, AC adapter cable, or external DC power cable,
and the grounding wire.
2. Grease one of the two rubber cable channels.
a. Apply a small amount of silicone grease (about the size
of a pea) onto your fingertip.
b. Lightly coat all four outer edges on the rubber cable
channel with grease.
c. Open the cable channel and lightly coat the inside of
both halves (the part with the grooves).
3. Lightly coat each cable with grease.
4. Place the greased cables in the channel grooves.
a. Open the greased rubber cable channel so that the
channel’s hinged side is oriented to the left.
b. Place each cable or wire into a single groove in the cable
channel, installing them from left to right.
•For the large cable channel, place smart sensor cables
in the grooves. If using the grounding wire, place the
black portion of it into the rightmost hole in the cable
channel (the hole farthest from the hinged side).
•For the small cable channel, place the AC adapter or
solar panel cable and any analog sensor cables or relay
wires in each of the grooves. Place larger cables in the
five grooves on the left closest to the hinged side and
smaller cables in the five grooves on the right.

Important: The cable diameter must be 4.0 mm (0.156
in.) to fit through one of the five smaller holes or 6.4
mm (0.25 in.) to fit through one of the five larger holes
in the rubber cable channel. If the cable diameter is too
small, build up the diameter using heat shrink. If the
cable is too big, splice on another cable with a smaller
diameter to fit through the hole.
5. Close the rubber cable channel making sure the cables and
wires remain in their grooves.
6. Press the cable channel into the opening until it is flush with
the outside of the case (when fully seated, the channel will
project slightly into the inside of the case). To reduce the
amount of excess cable in the case, gently pull the cables
toward you as you press the channel into place.
7. Using thumbscrews, install the plate on the cable access
opening to hold the rubber cable channel in place. (Use the
smaller plate for the top opening and the larger plate for
the larger opening.) Do not fully tighten the thumbscrews
yet; keep them loosely installed while you install the rubber
plugs in the next step.
8. Lightly coat rubber plugs with a small amount of grease and
use the plugs to fill any empty holes in the two cable
channels. There are large and small plugs; use the large
plugs in the larger holes and the small plugs in the smaller
holes. Insert the thin part of the plug into the hole and push
it in until the thick part of the plug fills the hole.
9. Repeat steps 2 through 8 with the other rubber cable
channel.
10. Use the included wrench to tighten the four thumb screws
on each of the two plates until the plates are flat against
the case.
Care and Maintenance
The station is designed for outdoor use, but should be
inspected periodically. When inspecting the station, do the
following:
•Verify the station enclosure is free of visible damage or
cracks.
•Make sure the station enclosure is clean. Wipe any dust or
grime off with a damp cloth.
•Wipe any water off the station before opening it.
•Check that all cables and wires are free of damage, such as
cracks, cuts, and splits.
•Make sure cables and wires are still fastened securely and
any conduit is still intact.
•Verify that all cables and wires are free of corrosion. If
moisture is visible inside the station or if there is any sign
of corrosion on the connectors, spray WD-40® or an
equivalent electronics-safe corrosion inhibitor on the
connectors. This will displace moisture and prevent
additional corrosion. Be sure to determine the source of
the moisture and fix it. Check the cable channel and cover
seals for any sign of moisture entry.

Battery Information
The station uses one rechargeable 4 volt, 10Ah, sealed lead-
acid battery. Use the AC adapter (AC-U30), solar panel (SOLAR-
xW), or external DC power cable (CABLE-RX-PWR) with your
own charging device to keep the battery charged. If using a
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. Without a charging device connected,
expected battery life varies based on the ambient temperature
where the station is deployed, the logging or sampling interval,
frequency of connections to HOBOlink, the number of channels
that are active, excitation in analog modules, the number of
tripped alarms, and other factors. Deployments in extremely
cold or hot temperatures, a logging interval faster than 1
minute, or a sampling interval faster than 15 seconds can
impact battery life. Estimates are not guaranteed due to
uncertainties in initial battery conditions and operating
environment.
Use the following table as a guideline for estimating how long
the station will run using a fully charged battery and no source
of external power. For these examples, the station has up to 10
smart sensors installed and no excitation enabled for the
analog sensor module.
Connection Interval Logging Interval Typical Run Time
10 minutes 1 minute 20 days
1 hour 15 minutes 50 days
6+ hour 30 minutes 75 days
All communications will stop if the battery voltage drops below
3.9 V. The station will stop logging if the battery voltage drops
below 3.6 V. If the station has stopped logging due to low
battery voltage, plug in an AC adapter, solar panel, or external
power source to recharge it. It may take several minutes for the
station to power back up; the lower the remaining voltage, the
longer it will take for power to return. Also note that it will take
longer for power to return with a solar panel than with an AC
adapter. If the charging device is not recharging a dead battery,
contact Onset Technical Support.
Important: Due to the self-discharge characteristics of this type
of battery, it is imperative that you charge the battery for at
least 12 hours every six months at minimum, even if you are
not actively using the station. Otherwise, permanent loss of
battery capacity may occur.
