Troubleshooting

• Select a slower connection interval in Readout Configuration.
• Consider setting up a second connection schedule at a less frequent rate by enabling Night Mode in Readout Configuration.
• The cellular signal at the device location may be weak or there may have been an interruption in cellular service. Consider repositioning the device to a location with a stronger signal if the problem persists.

• If you are using an external solar panel, make sure it is installed properly and functioning. The solar panel should provide enough power to recharge the battery during the day.
• Use the AC adapter to recharge the battery.

• RX2100 stations using the built-in solar panel may need to be repositioned if it is not receiving enough sunlight to keep the battery charged. Or, you can add an external solar panel.

Recharge the battery for 12 hours with the AC adapter. If the battery cannot be recharged, you will need to replace the battery. Contact Onset Technical Support or your Onset Authorized Dealer. It is always recommended that either a solar panel or AC adapter be connected all the time to provide a trickle-charge to the battery.

Important: The station uses durable, high-capacity Flash memory so data is retained even when the battery runs out of charge. Do not restart the device until the data has been recovered. If the battery cannot be recharged and you are still unable to read out the device, contact Onset Technical Support or your Onset Authorized Dealer as it may be possible to retrieve the logged data.

The RX3000 station should be powered down before installing a new module. Try unplugging the battery and any power charging devices (AC adapter, solar panel). If you installed an RXW Manager module, make sure it is plugged into the manager mote. Wait a few seconds and then reconnect the power. If the mote still isn’t recognized, turn the power off again and make sure the module is installed properly with the pins fully inserted in the connector on the station.

• For RX3000 or RX2100 stations: Check that the sensor appears in Sensor Configuration. If it does not, then use the Search button on the station to find the connected sensor and then press the Cloud/Connect button to reconnect to HOBOlink. For analog sensors, make sure "Enable this channel" is selected in Sensor Configuration.

• For U30 stations: If a sensor was added or changed while the device is logging, the device must be relaunched to detect the changes and begin recording data. Select "Force Relaunch on Next Connection" in Launch Configuration.
• Check for a loose connection in the sensors that are not logging.
• For U30 stations: If you are using the smart sensor expander board, make sure it is connected to the device's built-in smart sensor board with the short expander cable. See the U30 Station User's Guide for more details.
• Make sure you have not exceeded 100 meters (328 ft) of network cable for all smart sensors.
• Make sure you have not exceeded 15 smart sensor channels. Note that some smart sensors use multiple data channels. For RX3000 and RX2100 stations, check the smart sensor count on the LCD. For U30 stations, use HOBOware to see a list of all installed smart sensors in the Launch Logger window. Sensors are listed in ascending order by serial number. If more than 15 data channels are connected, the sensors with the higher serial numbers will be ignored and their data will not be recorded.

Any changes that you made in Launch Configuration or Readout Configuration will not take effect until the next time the station connects to HOBOlink. For example, if the connection interval for the station was set to two hours, then any change you made in Launch Configuration or Readout Configuration won't take effect until the next connection on that two-hour schedule.

If it has only been offline for less than hour, the mote may be temporarily offline due to a poor network connection. If the sensor has been offline for a long time, check its position and the battery. See Tips for Working with Wireless Sensors for details.

When configuring a logger with HOBOconnect, you must select whether data should be uploaded to HOBOlink from a gateway or from HOBOconnect. This also requires that HOBOconnect is connected to your HOBOlink account (check Settings in HOBOconnect). If you are using a gateway, make sure it is set up as described in the HOBO MX Gateway Manual. If any loggers were already logging before you set up the gateway, then you will need to reconfigure them and make sure to select to upload data via a gateway.

If you are not using the gateway, data will not appear in HOBOlink until you read out the logger with HOBOconnect. Your phone or tablet must have access to the internet to then upload the data from HOBOconnect to HOBOlink. See the HOBOconnect User's Guide at www.onsetcomp.com/hoboconnect for details on using the app.

• The indicators are very faint under direct sunlight. If no indicators appear to be blinking, shield the device from the light and check the indicators again.
• Check the Device Information panel on the device page and make sure the battery power is not too low. There needs to be at least 3.5 volts for logging to continue and 3.9 volts for cellular communication.
• The memory may be full if the device was not set to "Wrap when memory is filled" in General Configuration. Read out the device and relaunch it.
• The device may not have been launched. Check the Connections tab in in the Activity Log panel to see when the device is scheduled to connect or if it is awaiting its first call.

If you are missing data for a particular sensor, check that it was properly installed and configured. Remove and reconnect the sensor and check the status in HOBOware to verify that it can report accurate readings. If you find that it is not communicating, it may be damaged. Contact Onset Technical Support or your Onset Authorized Dealer.

In rare circumstances, a data file may become corrupt. Contact Onset Technical Support or your Onset Authorized Dealer.

Launches attempted with HOBOware will be overridden the next time the device connects to HOBOlink. If the HOBO U30 Station is communicating with HOBOlink, then it most likely has been relaunched in HOBOlink.

If this is the first time the device has been launched, make sure you have set the connection interval in Readout Configuration.

If this is not the first launch and the device is connecting but still not launching, then select "Force Relaunch on Next Connection" in Launch Configuration and wait for the next connection.

There is a known limitation with sharing files downloaded from HOBOlink on an iPhone or iPad using Google Chrome. Switch to Safari to open and share the file. Or, if the problem persists, use a computer or Android device to export the data and then open and share the file.

Data files downloaded from HOBOlink on an iPhone or iPad that are very large may not always open as expected. Change the parameters for the export to create a smaller file (i.e. reduce the time frame, sensors, or devices included in the export). Or, switch to a computer or Android device.
