| Reporting interval ≤ 30 mins: the device will send a specific number of LinkCheckReq MAC packets to the network server every 30 mins to validate connectivity; If there is no response, the device will re-join the network.

Reporting interval > 30 mins: the device will send a specific number of LinkCheckReq MAC packets to the network server every reporting interval to validate connectivity; If there is no response, the device will re-join the

network.

Set the number of packets sent|

When rejoin mode is enabled, set the number of LinkCheckReq packets sent.

ADR Mode| Allow network server to adjust data rate of the device.
Tx Power| Transmit power of the device.

Note:

1. Please contact sales for device EUI list if there are many units.
2. Please contact sales if you need random App keys before purchase.
3. Select OTAA mode if you use Milesight IoT cloud to manage devices.
4. Only OTAA mode supports rejoin mode.

LoRaWAN Frequency Settings:
Go to Settings > LoRaWAN Settings 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.

Examples:

• 1, 40: Enabling Channel 1 and Channel 40
• 1-40: Enabling Channel 1 to Channel 40
• 1-40, 60: Enabling Channel 1 to Channel 40 and Channel 60

All : Enabling all channels
Null : Indicates that all channels are disabled

Basic Settings
Go to Device > Settings > General Settings to change the reporting interval, etc.

Reporting Interval

| Reporting interval of transmitting current sensor values to network

server. Default: 1080 mins, Range: 1-1080 mins

Change Password

| Change the password for ToolBox App or software to read/write this

device.

Threshold Settings

Go to Device > Settings > Threshold Settings to enable the threshold settings and input the angle threshold. You can set a relative initial surface to measure the deviance from an initial one and if the device detects the angle of a certain axis reaches the threshold based on the initial position, it will upload the current data instantly.

Initial Position

| Click Setting to set current position of device as initial position to measure the deflection angle.

Click Clear to change the initial position back to (0.00°, 0.00°, -90.00°).

Note: after writing Setting or Clear configuration, click Read to read the device to check if the initial position changes successfully.

Over / °| The maximum/upper limit of angle threshold.
Below / °| The minimum/lower limit of angle threshold.

Alarm Condition

| Acceptable elements are “X”, “Y”, “Z”, “and”, “or” “only”, it takes 2 or 3 axes to complete an expression and the device will only read from left to right. If left blank, it will consider the condition as “or”.

Example:

1)   XandYorZ means (X and Y) or Z, that is XandY meets the threshold or Z meets the threshold.

2)   XorYandZ means (X or Y) and Z, that is XandZ meets the threshold or YorZ

meets the threshold.

Alarm Reporting Interval| After the threshold is triggered, the device will detect if the threshold is triggered again according to this reporting interval.

Alarm Reporting Times

| After the threshold is triggered, the device will detect according to Alarm

Reporting Interval and if still triggered, the device will send the certain number of alarms to NS.

Example:
When X axis is detected to 0° (0° – 1.91° = -1.91° < -1°), it will trigger the threshold and upload an alarm package right away. If it changes back to normal, the device will also upload a data package immediately; if not, it will send alarm package after 1 minute. This process will repeat 2 times .

Maintenance

• Fix the bottom of the device to the cover with a fixing screw.

Installation Location:

• Ensure the location of device is within the communication range of LoRaWAN® gateway and keep it away from metal objects.
• Ensure that the device is tightly attached without any gap to the surface to be measured of a certain object, and one of the 3 axes should be paralleled with the measuring axis of the object, otherwise, the result may not be correct.
