Overview
B1-Cport3102 is 2-ports serial to Ethernet converter. It adopts the Cortex-M7 solution, which has a main frequency up to 400MHz, powerful performance, fast transmission speed, and high reliability. Equipped with a deeply optimized TCP/IP stack, built-in hardware and software watchdog and a variety of keepalive mechanisms, B1-Cport3102 keeps online all the time. It supports TCP Client, TCP Server, UDP Client, UDP Server and HTTPD Client working modes, achieves data transparent transmission via simple configuration.
The B1-Cport3102 supports Modbus RTU Master for retrieving field site data from serial meters. After collecting data, users can convert serial data to MQTT json format data, allowing users to get field site data. This two-in-one design reduces system complexity and the amount of space required in the network topology, as well as overall installation time.
Modbus Gateway
It supports Modbus TCP and Modbus RTU protocol mutual conversion, a multi-host polling function.
Industrial Grade Design
The device conforms to industrial design standards. Reliable EMC protection and -40~85? operating temperature make it endure various complex industrial scenarios.
Dual Sockets
Each serial port supports connecting to two different servers at the same time. Two sockets are mutually backed up, providing higher reliability and better flexibility
