3.3 Format of Sending Packets
Format of Sending Packet explains the string format for different data
fields. In this chapter, you could learn the format usage about AVL data
fields.
This chapter shows you how to format data sent by VITA-350E. Firstly,
you must design the fields of data received to your server. Your server
should have the capacity to process the data which sent normally or re-
sent abnormally from VITA-350E. Secondly, you could transfer data
fields from raw data to format identifiers of VITA-350E.
The format identifiers supported by VITA-350E are list as follows:
