FMS (Fleet Management System)

FMS (Fleet Management System)

The FMS interface is an optional interface of various truck manufacturers. Since a direct connection to the vehicles’ internal bus system might affect vehicle reliability (as well as warranty), the FMS interface is designed to be the sole interface for a safe data connection to the internal network. iWave SAE J1939 protocol stack provides an efficient way to read FMS standard parameters.
