$PATC,IIHDG,RID,ssss<CR><LF>

5.11

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>

$HCHCC,hhh.h<CR><LF>

a=3 :

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.

$HCHDG,hhh.h,,,,*ssss<CR><LF>

e.g.

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>

where ssss is the serial number in ASCII decimal.

ROT with 8s average

ROT with 16s average

ROT with 32s average

ROT with 64s average

(cc is the checksum)

(ssss is the unit's serial number)
