NMEA PTID - 22
Description
Driver to decode tide height observations from any tide gauge receiver that can output a NMEA propietary PTID message.
The driver can handle multiple tide observations from more than one tide gauge station.
Tide station number and information type are entered as slots. (See image below)
- CH1 - Channel 1, This is the primary observation and most likely the tide
- CH2 - Channel 2, This is the secondary observation, this value is optional and not always present
- BAT - Battery, This is the voltage level of the battery of the tide gauge.

Decoding Notes
The status (6) field is used as Quality Indicator.
Fields 5, 7 and 10 are use internally in the driver to convert their corresponding values into either Meter for tide, Volt for battery level and pHa for Air pressure if present in Channel 2.
The Date (2) and Time (3) fields are ignored, instead the time of the message arrival is used as these values can be inaccurate.
