Module overview

USB turns MBUS from module to MBUS master and debug from module communication. This module connects the computer through USB, through which the module is debugged from the end to the main end, from the machine chip.Integrated chipFC722Unlike TSS721A, it has no spontaneous self collection, and has lower bus leakage current compared with discrete device FC722.

The module MBUS signal is completely isolated from the USB signal. There is no need to worry that the MBUS high level will damage the computer USB interface. MBUS signal part of the circuit from the MBUS bus power, nothing to do with USB!

Be careful:This module isMBUS From the moduleNot Master module!!!

Be careful:The new version of the module isGreen PCB!!!!!

MBUS introduction:

Meter Bus (MBUS) is a new type of bus structure. The main features of MBus are two non polar transmission lines to supply and transmit serial data at the same time, and each sub station (with different ID confirmation) is parallel to the MBus bus. When the MBus is used in the energy consumption intelligent management system of various instruments or related devices, the related data or signals can be collected and transferred to the concentrator and then passed to the main station through the corresponding interface. The use of MBus can greatly simplify the wiring and connection of the energy consumption intelligent management system, such as residential area, office space and so on, and has the characteristics of simple structure, low cost and high reliability.
