TRIMBLE ASCII INTERFACE PROTOCOL (TAIP)
Message Identifier
A unique two character message identifier consisting of alphabetical characters is
used to identify type messages. For example: PR for Protocol or VR for Version
Number.
Data String
The format and length of a data string is dictated by the message qualifier and the
message identifier. The data string may contain any printable ASCII character with
the exception of the >, SRM;ID_FLAG=T;*6F<
In this example, the checksum (6F) was generated by XOR'ing the ASCII codes for >
and S then XOR'ing that result with the ASCII code for R and so forth, up to and
including the * character.
Message Delimiter
The < character signifies end of a sentence and is used as the message delimiter.
