Diagnosis and working mode
Diagnostic function: The module is equipped with diagnostic LED indicator lights. The "power aux" indicator light is on, indicating that the auxiliary voltage is supplied by an external power source and the power unit is working properly; If the "power int" indicator light is on, it indicates that the auxiliary voltage is provided by the host device and the power supply unit is running well; The LED marked as "sc" will flash according to the data communication rate. By observing the flashing of this indicator light, the data communication status can be intuitively understood, making it convenient to quickly troubleshoot communication faults.
Working mode:
Master device mode: This mode is used when the bus connection module is connected to a device in the system that serves as the master device. In this mode, the module can actively initiate data requests, control signal transmission and other operations, and coordinate data interaction among slave devices within the system.
Slave device mode: If the bus connection module is connected to a device in the system that acts as a slave device, the slave device mode is used. At this point, the module responds to the instructions of the main device and performs data transmission and operation execution according to the requirements of the main device.
