JRC JLN-900 - Docking Log (PSALL); Remote Dimming Message (PSALR)

3.2.3 Docking log (PSALL)
Note this sentence was created when the VBW sentence lacked the capability to present stern
speed. The standardised sentence should be used whenever possible.

Log status character 'B'=valid bottom track,

rate of turn information. Field 3
contains transversal speed from
log, ?field 4 is invalid?
'E'=log error

Checksum
Example: longitudinal speed 1.32 knots, bow -1.11 knots, stern +0.44 knots:

This message is intended for using the NMEA network to control groups of indicators.
Whenever a $PSALR message is received by any indicator it adjusts the light level
accordingly. $PSALR messages are generated by SD indicators having remote dimmer
controls. (SD1 and SD2 indicators only uses field 2).
Example:
Increase light on SD1/SD2:
$PSALR,+,,*
Set a light level of 70% on instruments with id E:
$PSALR,,E,70*
