Appendix A.1.1. Pressure Data

Offset (where x is the offset		Notes
specified in the MD)
X + 0		Gage Pressure. A signed real number.
		Gage Pressure Units. A whole number which is used
X + 1		as a lookup into the table provide in section
		“Appendix A.2 Gage Pressure Units”
		Gage Pressure Indicating Letter
X + 2		‘A’ = 65
X + 2		‘G’ = 71
		‘G’ = 71
		‘T’ = 84
X + 3		Set to 1 If the pressure reading reports the status as
X + 3		‘OK’
		‘OK’
X + 4		Set to 1 If the pressure reading reports the pressure
X + 4		as a ‘SEA LEVEL’ reading
		as a ‘SEA LEVEL’ reading

If any fields are absent in the response to a poll for status data then the values are set to zero for that field.
