TX rate in Hz
* PS talker identifier (relative. heading)
* Calculated as magn. heading + magvar.
** Relative (geared synch./step) if PSIM identifier
* J50-1 will only read speed, not heading
New mess. priority
No data action
delay (sec)
* HDT if true, HDG if magn. steering compass
* Either true or magn. is calc. value if magvar is available
AP50 system, NMEA 183 messages
(applies for J50 and NI300X sw release V1R2 onwards)
