'''''Latitude''''' - Is calculated in the same way as longitude but since latitude maximum value is two times smaller than longitude it can produce a bit more accurate data. The coefficient for latitude is 93206,75. This coefficient is got in the following way: 16777215(maximum 3 bytes value) divided by 180 (maximum latitude value then 90 is added). This calculation is used to fit negative and positive values to 3 bytes width variable. | '''''Latitude''''' - Is calculated in the same way as longitude but since latitude maximum value is two times smaller than longitude it can produce a bit more accurate data.

'''''SBD AVL ID and flags''''' – Custom ID that will indicate what caused the record to be generated | '''Din/Dout info''' - Displays configured IO elements in parameter id 99422 (only din/dout). If IO is not set, it will send be replaced by 0. | ||

'''Reserved''' - Not used anywhere. | |||

'''Speed''' – Indicates the speed (from GNSS) of the vehicle if configured. If not (or in case of no gps) – will display 255. | |||
