A proprietary NMEA sentence is supported which allow the user to dene up to 4
additional parameters to be displayed from any specied NMEA sentence(s). This
proprietary NMEA sentence has the following format:
$PSKPPCCPNMEA, <Auxiliary number>,<Header>,<Data Field number.>,<Type>,
< Status eld number >,< Status valid character >,<Text>*hh<CR><LF>
Example: Fetch a proprietary NMEA sentence for roll & pitch and display the values:
$PPPRP
,<a>,<b><CR><LF> where <a> is roll data parameter and <b> is pitch data
parameter.
Fetch also the parameters for both port and starboard rudder angle from the following
NMEA
message: $SGRSA,<a>,A,<b>,A<CR><LF> where <a> is starboard rudder
sensor and <b> is port rudder sensor and ’A’ is status for each corresponding data eld
parameter. The following NMEA sentences must be sent to the Compact Multi Repeater
to accept these parameters:
$PSKPPCCPNMEA,1,PPPRP,0,8,,ROLL<CR><LF>
$PSKPPCCPNMEA,2,PPPRP,1,8,,PITCH<CR><LF>
$PSKPPCCPNMEA,3,SGRSA,0,8,1,A,SRUD<CR><LF>
$PSKPPCCPNMEA,4,SGRSA,2,8,3,A,PRUD<CR><LF>
Select the AUX1 in the meny to display the roll parameter, select the AUX2 in the
meny to display the pitch parameter, select AUX3 in the menu to display the starboard
