HOBO RX3000 RXW Manager (RXMOD-RXW-xxx) Manual

The HOBO RX3000 RXW Manager is a module and mote designed to work with the HOBOnet
Wireless Sensor Network. When the RXW Manager module is installed in an RX3000 station, data
is transmitted wirelessly from sensor motes across the network to the RX3000 station and then
uploaded to HOBOlink® web-based software. You can use HOBOlink to monitor the network, view
graphs, set up alarms, download data, and more.

Installing the Module

The module must be installed in an RX3000 station before the
motes in the RXW Wireless Sensor Network can join the network.

Important: If you have not already registered the RX3000
station with HOBOlink and set up the station communications,
follow the instructions in the RX3000 Quick Start.

To add a module:

1. Stop the station if it is currently logging. Press the Connect
button and wait for the station to connect to HOBOlink so
that all the latest data is offloaded before adding a new
module.

Press Connect if the station was
logging to upload the latest data

2. Once the station is done connecting to HOBOlink, power it
down by disconnecting the battery and unplugging any
charging device.

3. Insert the connector on the back of the module into the
receptacle in the left or right module slot.

7. The station should automatically connect to HOBOlink
(press the Connect button on the station if it does not).
Check your station’s page in HOBOlink to make sure the
new module is listed.

8. If you added the module to an RX3000 station that was
previously in use, you will need to update the station
firmware. (If you have a new station, go to the next step.)
To update the firmware:

a. In HOBOlink, go to Devices > List and click your station

name.

b. On the station page, click Overview and scroll down to

Device Information.

c. On the General tab under the Firmware Version, click the

firmware upgrade link.

4. Using a Phillips-head screwdriver, tighten the screw at the
bottom of the module.

5. Plug the cable from the RXW Manager mote into the jack on
the module, making sure the cable is inserted through the
bottom of the station case. Do not reconnect the power on
the station until the mote is plugged in as shown.

6. Plug in the battery and then the charging device, and wait
for the station to power up. Verify that the new module is
listed on the LCD screen with a checkmark. Because the

d. Select Upgrade on Next Connection and click Save.

e. Press the Connect button on the station.

Press Connect to connect to HOBOlink
and start the firmware upgrade

f. Wait for the firmware upgrade to complete. The upgrade

icon should be gone in HOBOlink once the upgrade is
successful. If the station firmware is not successfully
installed, it could be because there is an interruption in
cellular service or poor signal strength. Contact Onset
Technical Support at 1-800-LOGGERS, 508-759-9500, or
www.onsetcomp.com/support/contact for help.

9. Set the logging interval for the module in HOBOlink. Go to

Devices > List, select the icon next to your station, and
select Module/Sensor Configuration. Select Module <1 or
2>: Wireless Sensors Logging, enter a logging interval (how
often the sensor motes will record data), and click Save.
