Every cell/unit on the battery system is assigned a single Vigilant sensor. That sensor is wired directly to the battery connections with as short of wire as possible. All sensors are connected in a loop via RJ12 comms cable back to the monitor. This allows the sensors to be powered from the monitor while greatly reducing the amount of sensing cables required. Eagle Eye has past provided systems with longer cable runs as well as wireless technologies and found that both are subject to noise from the environment, decreasing the reliability of the system overall.
