kPowerUp (frame ID 23)
This frame is sent from the module after wake up from power down mode. The frame has no
payload. Since the module was previously powered down which drives the RS-232 driver TX line low
(break signal), it is recommended to disregard the first byte.
kSetAcqParams (frame ID 24)
This frame sets the sensor acquisition parameters in the unit. The payload should contain the
following:
PollingMode FlushFilter SensorAcqTime IntervalRespTime
UInt8 UInt8 Float32 Float32
Payload
PollingMode: Flag to set push/poll data output mode. Default is TRUE (poll mode).
FlushFilter: Flag to set FIR filter flushing every sample. Default is FALSE (no flushing).
SensorAcqTime: The internal time interval between sensor acquisitions. Default is 0.0 seconds, this
means that the module will reacquire immediately right after the last acquisition.
IntervalRespTime: The time interval the module output data in push mode. Default is 0.0 seconds,
this means that the module will push data out immediately after an acquisition cycle.
kGetAcqParams (frame ID 25)
This frame queries the unit for the acquisition parameters. The frame has no payload.
kAcqParamsDone (frame ID 26)
This frame is the response to kSetAcqParams frame. The frame has no payload.
kAcqParamsResp (frame ID 27)
This frame is the response to kGetAcqParams frame. The payload should contain the same payload
as the kSetAcqParams frame.
