Be careful:This module is MBUS slave module,Not master module!!
Be careful:New module Green PCB!!!!!
USB to MBUS slave module, master slave communication debugging, no spontaneous self collection!
USB turns MBUS from module to MBUS master and debug from module communication. This module connects the computer through USB interface. Through this module, the module is debugged from the module to the main module, and the chip is FC722 from the machine chip!
The integrated chip FC722 is different from TSS721A without spontaneous self collection, and has lower bus leakage current compared with discrete device FC722.
Analog slave machine (water heat meter, etc.) communicate with main equipment, and monitor MBUS bus.
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!The characteristics of this product:
1. Fully consistent with M-BUS international standards and national standards
2. Bus current 200uA - 3mA continuous
3. The bus voltage 12V-42V can be adapted
4. Enhanced 5V, 3.3V steady voltage output
5, 300 - 9600BPS communication rate
6. Support UART, high stability
Application domain:
- Communication debugging of master slave module for analog intelligent water meter meter reading application
- Automatic meter reading of analog smart gridApplication of master slave module communication debugging
- Analog intelligent home control networkApplication of master slave module communication debugging
- Analog fire alarm and linkage networkApplication of master slave module communication debugging
- Analog central air conditioning control systemApplication of master slave module communication debugging
- Analog intelligent sensor networkApplication of master slave module communication debugging

MBUS profile:
Meter bus (meter bus referred to as: MBus) is a new kind of bus structure, MBus is two non-polar transmission line to also supply and serial data transmission, and each sub station (with a different ID confirmation) in parallel with the MBus bus. The MBus is applied to the energy consumption of all kinds of instrument or apparatus for intelligent management system, of related data or signals are collected and transmitted to the concentrator, and then through the corresponding interface is transmitted to the main station. MBus can greatly simplify the residential area, office space and other energy consumption intelligent management system wiring and connection, and has the characteristics of simple structure, low cost, high reliability.
Statement:
All components of the module are exposed outside, and customers can not touch other strong electricity when using them.
