IOT
has the following features: 1) RS485/422 serial optical coupling isolation, isolation voltage is 1500V. Apply to the strong interference environment which normal serial device server cannot work properly in. Effectively isolate the ground circuit between the serial port device and the serial port server. 2) Built-in lightning protection of power supply: built-in pressure sensitive resistance and ceramic discharge tube can effectively protect the internal circuit of serial device server in the case of power surge. 3) Industrial power supply: it has two kinds of power supply connection modes: terminal and power plug. Can be 9~48V wide voltage power supply. 4) It has three serial port interfaces of RS232/485/422. 5) RS485/422 has capacity of 256 loads. 6) Ethernet port with 2KV surge protection. 7) Abundant panel indicator lights are convenient for debugging: in connection, there is not only a 100M_LINK light indicating whether the network line is connected, but also a LINK light indicating the establishment of TCP connection. Data indicator light has independent indicator light for "serial port to Ethernet port", "Ethernet port to serial port". Convenient for site debugging.
2.2 Software functions 1) Support TCP server, TCP client, UDP mode, UDP multicast. Support TCP server side function as TCP client. Support 30 TCP connections as a TCP server and 7 destination IP as a TCP client. 2) The baud rate supports 1200~115200bps, data bits support 5~9 bits, and parity can be None, Odd, Even, Mark, Space. CTS/RTS hardware flow control and XON/XOFF soft flow control. 3) Support the function of sending MAC address when device connecting to facilitate cloud management of devices. 4) Provide search, configure the device secondary development package DLL on PC. 5) Support Web browser configuration, support DHCP dynamic access IP, DNS protocol connect domain name server address. 6) Support remote search device, configure device parameter, device program upgrade on cloud. 7) Support remote viewing of TCP connection status, serial port data sending and receiving status of devices through software. Virtual serial port supports data monitoring. 2.3 Advanced software features The 4 number in 5143BI indicates that advanced soft functions are supported, including: 1) Support Modbus gateway function, support Modbus RTU to Modbus TCP. The storage Modbus can be supported, and the equipment data can be collected automatically and stored. Modbus gateway for non-storage mode is also supported. 2) Support for multiple hosts: support Ethernet port allows multiple computers to access the same serial port device at the same time in a question-answer query mode. 3) Support for custom heartbeat and registration package features: easy to communicate with the cloud and identify device. 4) Support the function of TCP needs password authentication to establish connection to ensure connection security. 5) Support "transcoding" function, which can realize the translation of protocols for specific devices and allow different devices to connect to the unified software platform. 6) Support data submission and sending function in HTTP mode, and the cloud can directly use HTTP GET instructions to interact with the serial port data of the device.
