All of the AVL ID's that are above 255 need to use Codec 8 Extended instead of Codec 8. The reason being, that Codec 8 AVL ID's have 1 Byte (Maximum value 255), while Codec 8 Extended has 2 Bytes for AVL ID's (Maximum value 65535). Also Codec 8 Extended can have variable size I/O elements.

record and packet size

An AVL record contains basic AVL data. An AVL packet conveys one or more AVL records. An AVL packet is sent trough the cellular network as a cellular packet.

AVL record size:

  • minimum: 45 bytes (all IO elements disabled);

  • maximum: 783 bytes.

AVL packet size:

  • minimum: 1 record;
  • maximum: 1 kbyte (for FMB devices).

Most cellular network operators have a minimum billed packet size of 1 kbyte.

The cheapest way to set up the device would be to send as many records as they fit in a maximum size packet 81 kbyte).
