Configure the output sentence structure and type:
$PATC,IIHDG,CFG,abc<CR><LF>
[Replies with the standard acknowledge sentence $PATC,HCHDG,ACK<CR><LF>. ]
Where 'a' is heading sentence type as follows:
a=0 :
$HCHDG,hhh.h,,,,<CR><LF>
a=1 :
$HCHDT,hhh.h,T<CR><LF>
a=2 :
$HCHDM,hhh.h,M<CR><LF>
a=3 :
$HCHCC,hhh.h<CR><LF>
a=4 :
$HEHDT,hhh.h<CR><LF>
a=5:
no heading data sent
hhh.h is the compass heading in degrees
(this compass heading field will be omitted when auto-calibration is in process)
and 'b' is sentence end structure as follows:
b=0 : direction sentence will NOT include checksum nor unit ID serial number.
e.g.
$HCHDG,hhh.h,,,,<CR><LF>
b=1 : direction sentence will include a checksum.
e.g.
$HCHDG,hhh.h,,,,*cc<CR><LF>
b=2 : include the serial number.
e.g.
$HCHDG,hhh.h,,,,*ssss<CR><LF>
number)
and where 'c' has the following significance:
c = 0 or is missing means no ROT
c = 1
c = 2
c = 3
c = 4
The form of the transmitted sentence is:
$HFROT,zxxx.x,A*cc<CR><LF>
Except when a=4 when the form is
$HEROT,zxxx.x,A*cc<CR><LF>
ROT with 8s average
ROT with 16s average
ROT with 32s average
ROT with 64s average
11 of 12
(cc is the checksum)
(ssss is the unit's serial
