Summary

Features

• Multi-installation method design: Supports panel installation/rail installation.
• Compact size: Compared with ordinary serial port servers, it has a smaller width and does not take up much space.
• Terminal power supply, wide voltage input of 9 to 24V, with reverse power protection.
• Terminal RS485 interface, with baud rate support ranging from 300 to 921600bps.
• It is equipped with RS485 hardware interface protection.
• Rich panel indicator lights facilitate debugging: In terms of connection, there is not only a LINK light indicating whether the network cable is properly connected, but also a LINK light indicating the establishment of a TCP connection. For the data indicator lights, there are independent indicator lights for "serial port to network port" and "network port to serial port".
• Supports TCP server, TCP client, UDP mode and UDP multicast. When acting as a TCP client, it also supports the functions of the TCP server side. As a TCP server, it supports 30 TCP connections; as a TCP client, it supports 7 destination ips.
• The baud rate supports 300 to 921600bps, the data bit supports 7 to 8 bits, and the check bit can be in five ways: no check, odd check, even check, marked, and space.
• Support the function of sending MAC addresses when devices are connected, facilitating cloud management of devices.
• Provide a secondary development package DLL development library for searching and configuring devices on the computer end.
• Support Web browser configuration, support DHCP dynamic acquisition of IP, and DNS protocol connection to domain name server addresses.
• Support remote cloud search for devices, configuration of device parameters, and device program upgrades.
• Support remote viewing of the TCP connection status, serial port data transmission and reception status of the device through software. The virtual serial port supports the data monitoring function.
• Support Modbus gateway function and support Modbus RTU to Modbus TCP conversion. It can support storage-type Modbus, automatically collect device data and store it. It also supports Modbus gateways in non-storage mode; Support the ZLMB configurable table Modbus gateway function.
• Support for multi-host function: Under the question-and-answer query mode, it supports the network port end to allow multiple computers to access the same serial port device simultaneously.
• Support MQTT gateway function.
• Supports JSON to Modbus RTU and 645 instrument protocol, and supports data upload in HTTP POST and HTTP GET formats.
• Support the NTP protocol to obtain network time, which is used for serial port output and the latter for uploading protocol content.
• Supports custom heartbeat packet and registration packet functions: Facilitates communication with the cloud and device identification.
• Support the function of password verification required for TCP connection establishment to ensure connection security.
• It supports data submission and distribution functions via http. The cloud can directly interact with the serial port data of the device using the http GET command.
