HOBO RXW Smart Sensor Input Mote (RXW-OBUS-xxx) Manual 1-800-LOGGERS 3 www.onsetcomp.com 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 Press this button for 3 seconds for the moter to join the network Press this button to view the module where the RXW Manager is installed Press this button so the station is ready to have motes join the network Press this button again to stop searching for motes
HOBO RXW Smart Sensor Input Mote (RXW-OBUS-xxx) Manual 1-800-LOGGERS 4 www.onsetcomp.com 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. Store the solar panel connector here when using lithium batteries Make sure solar panel cable is installed when using rechargeable batteries
