This module is used for MBUS master and slave module communication debugging, and the module is used as the slave to communicate with the host terminal through the USB terminal. The integrated chip FC722 is used as the slave end, which is different from the TSS721A without self-receiving, and has lower bus leakage current than the discrete device circuit integrated chip. The module signal is completely isolated from the USB signal, so you don't have to worry about For MBUS high level damage to the computer USB interface! The signal circuit takes power from the bus and has nothing to do with USB!

Features:
1. Full compliance with M-BUS international standards and national standards
2, bus current 200uA - 3mA continuous
3, bus voltage 12V-42V can be adapted
4, enhanced 5V, 3.3V regulated output
5, 300-9600BPS communication rate
6, support UART, high stability

Application areas:
1.Communication debugging of master-slave module for simulating intelligent water meter gas meter heat meter reading meter application

2.Communication debugging of master-slave module for simulating smart grid automatic meter reading application

3.Communication debugging of master-slave module for simulating intelligent home control network application

4.Communication debugging of master-slave module for simulating fire alarm and linkage network application

5.Communication debugging of master-slave module for simulating central air conditioning control system application

6.Communication debugging of master-slave module for simulating intelligent sensor network application

Meter Bus (Meter Bus: ) is a new bus structure. The main feature of Meter Bus is two non-polar transmission lines to simultaneously supply and transmit serial data, and each sub-station (confirmed by different ID) is connected in parallel on the bus. . When Meter Bus is used in the energy-based intelligent management system of various meters or related devices, relevant data or signals can be collected and transmitted to the concentrator, and then transmitted to the primary station through the corresponding interface. The use of Meter Bus can greatly simplify the wiring and connection of energy-consuming intelligent management systems such as residential quarters and office spaces, and has the characteristics of simple structure, low cost and high reliability.
