4.2 Checking Environment Monitoring Cables
The sensors detect various monitoring parameters and send them to the EMU for processing.
The H304ESC board converts the monitoring parameters of the sensors and reports the converted
parameters to the control system. Therefore, make sure that the connection from the H304ESC
board to the control system is correct.
