6.5. Appended DigiQuartz Telegram (VP500P)
The VA500P can be configured to output an additional DigiQuartz type telegram appended to the conventionally
selected and configure telegram. This allows a separate pressure data telegram to be broadcast to an INS, for
example.
This DigiQuartz type telegram contains the instrument pressure reading in PSI, not corrected for latitude and the
tare NOT applied, i.e.PSIA.
In addition the psia unit can be included in the telegram if required.
