ST200
This PGN is transmitted in response to a PGN 126208 Request Group Function message. Fields 1 and 3 must both be fully specified in the request in order for this PGN to be
transmitted.
This PGN does not respond to ISO Requests (PGN 59904).
This PGN may be used along with an alternative speed sensor (e.g. GPS) to create a frequency versus speed profile for use in calibrating the paddlewheel speed sensor within the
device.
Field 5, duration of interval, will nominally be the same as the update rate, but reflects the actual duration, whereas the update rate setting reflects the desired duration.
