Notes
This PGN is transmitted in response to a PGN 126208 Request Group Function message. Fields 1, 3, and 4 must each 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 performs the same function as the received proprietary NMEA 0183 command, $PAMTC,OPTION. See the description of that command for a full description of the
use of this feature.
Although this is a fast-packet message, the version with this PID fits into a single CAN frame.
