: ADM-5850G Industrial Modbus Gateway Server - MODBUS RTU/ASCII to Modbus TCP Converter with PLC Serial Port Support. This industrial Modbus gateway server converts Modbus TCP to MODBUS RTU/ASCII, equipped with RS485/422/232 and Ethernet ports, and supports Modbus master-slave functionality. Function Introduction: The Modbus protocol is the most widely used protocol in electronic industrial equipment and has become a general industrial standard. Through this protocol, Modbus devices (such as PLCs, DCSs, HMIs, and instruments) can communicate with each other via network or serial port. However, the Modbus protocols used in serial ports and Ethernet are different, therefore a gateway is needed to perform communication conversion between the two protocols. The ADM-5850G is a Modbus gateway product specifically designed to connect Modbus TCP devices and Modbus RTU/ASCII devices. The ADM-5850G features Modbus RTU/ASCII and Modbus TCP protocol conversion. It integrates Modbus TCP, Modbus RTU, and Modbus ASCII protocols, and its serial port can be configured as an RS-232, RS-485, or RS-422 interface via software. You can easily connect Modbus serial devices to Modbus Ethernet devices. Product features: 1. 32-bit ARM Cortex-m3 CPU. 2. One 10/100M Ethernet interface. 3. Supports RS-232, RS-422, and RS-485 serial port modes. 4. Configurable baud rate, data bits, stop bits, and parity bits. 5. Integrated ARP, IP, ICMP, IGMP, UDP, TCP, DHCP, DNS, MODBUS TCP, MODBUS RTU, and MODBUS ASCII protocols. Offers 4 operating modes: RTU Master -- TCP Slave, TCP Master -- RTU Slave ASCII Master -- TCP Slave, TCP Master -- ASCII Slave 7. Supports up to 32 Modbus TCP Masters and 4 Modbus TCP Slaves 8. Automatic character time interval adaptation function 9. Provides ID mapping function for managing host ID numbers 10. Local port, target IP address, and target port number can be set. 11. Can be configured via Web server, Telnet, and MG configuration tool. 12. MG configuration tool supports Windows 98/Me/NT/2000/XP/WIN7/WIN8/WIN10 operating systems. 13. Industrial-grade design, capable of stable operation in harsh environments. Package List: Modbus Gateway *1 Power Adapter *1 ( Please check if a power adapter is included in the package.
