***************************************
Plug-in USB to MBUS host module, water and gas heat meter debugging
******************************************************
***************************************
There is voltage on the MBUS bus, reminding buyers to buy MBUS host must have bus protection function!
Unprotected features may cause the computer's USB serial port to crash and may cause permanent USB damage.
Our module bus can be completely shorted, please see the test chart!
This module contains two sets of MBUS interfaces (the same MBUS is divided into two groups) to facilitate the connection of multiple slave devices!
USB-B interface, especially suitable for the production line is often plugged and used.
Please use the store to provide a USB driver, otherwise it will not communicate properly!
Application field
Smart energy meter, gas meter, heat meter, smart grid meter reading application with MBUS
Smart home control, fire alarm and linkage network applications with MBUS
Central air conditioning control with MBUS, intelligent sensor network application
Module characteristics
1, fully in line with MBUS international standards and national standards
2, compatible with all systems including win10
3, USB power supply, no external power supply required
4, USB hot swap, safe and stable
7, the shell size is small, easy to carry out on-site debugging
8, the shell does not have any text or pattern logo, customers can engrave the logo.
9, the module has no spontaneous self-receipt and error in the normal load range
10, short circuit protection low power function.
After the bus is shorted, the USB indicator goes out and the internal auto-shutdown bus enters the protection state.
About 4S detects whether the bus is short-circuited, and the short-circuit is automatically recovered in 4S, and the USB indicator is automatically restored.
The module enters protection and low power consumption and the computer USB will not die (Hint: USB dead needs to restart the computer to recover).
10, communication baud rate 300~9600 can be adapted to a maximum of 19200bps.
11, according to the load can bring about 10 standard MBUS slave devices.
19200 communication waveform
Buyers note:
1. The MBUS host module can only communicate with the slave module. The master module cannot communicate with the master module. The slave module cannot communicate with the slave module.
There can only be one host on the same MBUS bus, and there can be no more than two or more hosts.
2, USB power supply capacity is limited, MBUS bus can load up to 10 standard slave devices, too many slave devices will make the module into overload protection state.
3, bus protection function, the module will not be damaged after the MBUS bus is short-circuited, but try to avoid long-term short circuit.
4, all interfaces of this module can not touch the strong electricity
