$PATC,IIHDG,TXP,uuuu<CR><LF>

Set the Output update period:

Valid range is u=100 (default) to 2500 milliseconds. This is limited by the

maximum data rate of NMEA-0183 output at 4800 baud.

4.2.19

$PATC,IIHDG,TXY<CR><LF>

Toggle RXY

This command sets a flag to enable the transmission of the data of the

RXY command continuously interleaved with the heading. By sending the

command again the flag is cleared; it is also cleared on power-up.

4.2.20

This command is used by Autonnic's updater software which runs under

Microsoft Windows. It is used to send .aeh files to install a new version of

firmware.

4.2.21

Interleaved with the normal data there is a special message sent every

500ms if the field strength is deemed to be out of range.

Typical examples are:

Low:

$PATC,HCHDG,MFE,119,LOW*65 interleaved with $HCHCC,*6F

High:

$PATC,HCHDG,MFE,1652,HIGH*06 interleaved with $HCHCC,*6F

Where the value following the MFE is a representation of the field

strength.
