Air Data Computer Format
The Air Data computer transmits once per second using the following parameters:
Baud:
9600
Parity:
None
Start Bit:
1
Data Bits:
8
Stop Bit:
1
Update Rate:
1 msg/sec
Air Data messages are accepted when the serial port is set to "ENCODER". A packet consists of a set of ASCII
message strings. The first character of each packet is an ASCII Start-of-Text (STX = 02H). The last character of each
packet will be an ASCII End-of-Text (ETX = 03H).
Each message string begins with one ASCII character to identify it as an Air Data message ("Z"). The second
character identifies which message it is. The rest of the string consists of one or more alphanumeric ASCII fields.
Each message field ends with a carriage return, line feed (CR = 0D0AH). All numeric fields are ASCII decimal, right
justified and zero filled. If the Air Data Computer cannot supply data in a particular field, the field is filled with dashes
("-" = 2DH). The table on the next page lists the valid message strings.
