Configuration Messages

Accelerometer Sensor Configuration (16200)

Configure accelerometer behavior and reporting thresholds. Sent with tsmEv: 30.

}]

General Configuration

Field	Default	Description
`transactionId`	-	Request tracking ID (0–2,147,483,647)
`intervalMultiplier`	1	Multiply base measurement interval
`fullScale`	8	Full-scale setting in G (device selects closest supported value)

Mode Configuration

Mode	Name	Description
`0`	Disabled	Accelerometer off
`1`	Orientation	Report 3D orientation (message 1111)
`2`	Machine monitoring	Report vibration histograms (message 16100) + optional orientation

Reporting Thresholds

Field	Default	Description
`orientationHysteresis`	5°	Angular change threshold for orientation reporting
`energyLevelThreshold`	1	Minimum energyLevel to trigger 16100 event
`activityLevelThreshold`	0.001%	Minimum activityLevel to trigger 16100 event
`impactThreshold`	1 mG	Minimum impact to trigger 16100 event

Tip

Adjust thresholds based on your use case. For sensitive machine monitoring, lower the thresholds. For battery optimization, raise them to reduce unnecessary transmissions.

Example - Read current configuration:

[{
    "tsmId": 16200,
    "tsmEv": 30,
    "tsmDstTuid": "TSPDXXSERIAL1",
    "transactionId": 2147
}]

Example - Enable machine monitoring mode:

[{
    "tsmId": 16200,
    "tsmEv": 30,
    "tsmDstTuid": "TSPDXXSERIAL1",
    "transactionId": 2147,
