TTL-MBUS Master/Slave Converter - UART to M-Bus Communication for Smart Meter Reading & Water/Gas/Electric Energy Monitoring

TTL UART serial port to MBUS Master Slave Converter communication Module f/ Smart control / energy heat water meter debuggingNote:As long as the interface is mbus, it can work Use the corresponding software to call the serial port recognized by the computer for communicationWe only have drivershttp://115.28.16.44:81/file/6382.zipThe module is data transparent transmission The module itself does not require softwareIf you want to communicate with the instrument panel Find the software for the instrument and call the serial port recognized by the computerTTL to MBUS, serial to MBUS host moduleTTL to MBUS Master module, serial to MBUS master module. MBUS meter reading module applied to water, gas, heat, meter. Input wide voltage range 4V-18V, compatible with various TTL levels, TTL level can be set, bus with Short-circuit protection, self-recovery when short-circuit is withdrawn, ultra-low power consumption in short-circuit protection state.The module is compatible with a variety of TTL levels, and can be flexibly used in other modules such as wireless RF to MBUS module, GPRS to MBUS, 485 to MBUS and so on.TTL to MBUS slave moduleTTL signal and MBUS signal optocoupler isolation, do not interfere with each other, MBUS receiving circuit to take power from the bus, do not need a separate power supply, but because the TTL signal and MBUS signal optocoupler isolation, so the optocoupler needs separate power supply! The module uses FC722 slave MBUS chip, stable and strong anti-interference. Ultra-small size is easy to install with any device!parameters:1, communication baud rate: 300-9600bps2, TTL signal: compatible 3.3V, 5V or other3, bus voltage12V-42V can adapt4,Bus current200uA-3mA continuous5, VIN: TTL signal voltage value (if TTL is 3.3V, VIN input 3.3V voltage; TTL is 5V, VIN input 5V voltage)6, data interface: TXD external TXD; RXD external RXD7No self-reception (TSS721 internal Uart is a closed loop so there is spontaneous self-discovery, and this module does not)
