LoRaWAN Frequency Settings: Go to Setting > LoRaWAN Settings of ToolBox App to select supported frequency and select channels to send uplinks. Make sure the channels match the LoRaWAN® gateway. If frequency is one of CN470/AU915/US915, you can enter the index of the channel that you want to enable in the input box, making them separated by commas.
3.3 Basic Settings Go to Device > Setting > General Settings of ToolBox App to change the reporting interval, etc. Parameters Device Mode Description Select from Standard Mode, Bin Mode or Parking Lot Mode. Reporting interval of transmitting data to network server. Standard Mode: 10 minutes as default; Reporting Interval Bin mode: 20 minutes as default; Parking Lot Mode: 1080 minutes as default. If the sensor detects the occupancy status change, it will report immediately.
Tilt & Distance Switch Change Password When detecting that the offset angle is greater than 20 degrees, turn off the distance sensor. Change the password for ToolBox App or software to access this device. 3.4 Advanced Settings 3.4.1 Calibration Settings Go to Device > Setting > Calibration Settings to enable calibration. EM400-MUD supports two calibration types. Numerical Calibration: users can define calibration value to correct every distance.
according to collecting interval. If threshold is triggered, it uploads the current data once instantly. Note: threshold setting is only for bin mode and standard mode. Parameters Collecting Interval Threshold Dismiss Report Description Collecting interval to detect distance, this should be smaller than or equal to reporting interval. When the collected value changes from outside the threshold to within the threshold, a threshold release packet will be reported. 3.5 Maintenance 3.5.1 Upgrade 1.
3.5.2 Backup EM400-MUD support configuration backup for easy and quick device configuration in bulk. Backup is allowed only for devices with the same model and LoRaWAN® frequency band. 1. Go to Template page on the App and save current settings as a template. You can also edit the template file. 2. Select one template file which saved in the smartphone and click Write, then attach to another device to write configuration. Note: Slide the template item left to edit or delete the template.
3.5.3 Reset to Factory Default Please select one of following methods to reset device: Via Hardware: Hold on power button (internal) for more than 10s. Via ToolBox App: Go to Device > Maintenance to click Reset, then attach smartphone with NFC area to device to complete reset. 4. Installation 1. Drill two holes on the container cover according to the location of device mounting holes.
2. Put the device under container cover and align the holes in order to perfectly screw the bolts into the holes from the other side of the cover. Besides, the device can also be fixed by two M4 mounting screws and wall plugs. Installation location: In order to provide the best data transmission, please ensure the device is deployed within the signal range of the LoRaWAN® gateway and keep it away from metal objects and obstacles.
When EM400-MUD is in waste bin mode, place the device in the center of waste bin mode and here are some recommended sizes of waste bins: when the height is 88cm, the minimum radius should be 24cm. 5.
