This is a high-performance dual converter with bus interface and communication protocol. On the bus interface, the M-BUS bus to Ethernet B:RS485 is realized. In terms of communication protocol, CJ/T-188, European standard first-level address protocol, European standard second-level address protocol, and user-defined protocol to standard MODBUS- or MODBUS-RTU are realized, and it also supports server and instrument communication parent mission. The user can obtain the data of various meters connected to the converter by reading the registers with the MODBUS-/MODBUS-RTU protocol through the Ethernet B:RS485 interface. The converter realizes the conversion function of the physical layer and the protocol layer at the same time. Its built-in isolation circuit can effectively protect the equipment connected to the serial port. This converter is suitable for any MODBUS master station to read the data of M-BUS equipment. The converter uses the MODBUS-RTU protocol to support the reading of 100 pieces of instrument data. At the same time, the converter also supports the parent mission mode. The parent mission mode can realize the parent mission between the host and the M-BUS slave. The parent mission mode supports up to 500 Block meter Color: As shown Material: plastic Package Contents: 1 x to Ethernet Converter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
