4. PACKET PROTOCOL

The Developer/User should have a thorough understanding of each packet/parameter before proceeding to the same. Users are advised to memorize the following statement listed below in note, which is commonly used in packets.

1) Start of packet is ‘~’ character and End of packet is ‘^’ character. A valid packet should start with ‘~’

character and end with ‘^’ character. E.g.. ~Valid Packet^ Field Description ~ Start of Packet ^ End of Packet

2) CCN is Control/Call Center Number. 3) Parameter CheckSum is XORing of all characters in the message from Start of packet ‘~’ to ‘*’

( ‘*’ is excluded). 4) In this document Device refers as AVL-500 Box. 5) Date in DDMMYY format. 6) Time in HHMMSS 24 hour format (e.g.. 03:30:45PM is 153045) 7) Speed in Km/Hr. 8) Latitude and Longitude is in DegreeMinuteDotMinutes (DDMM.mmmmm) format. 9) The format of POSITION DATA is given below:
