Industrial Din Rail 1-Channel CAN Bus + 1-Channel RS232-422-485 Server (Mini)

This industrial rail-mounted CAN bus server, with an IP40 protection rating, instantly connects serial devices to the internet, allowing centralized management of distributed serial devices and hosts over the network. It supports one CAN bus, one RS422/485/232 serial port, and one 100M Ethernet channel. It can be mounted on a 35mm rail or on a wall, meeting the needs of diverse applications.

This CAN bus and serial server supports multiple network protocols, including TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, and SNMP. It offers comprehensive management features, including access control, quick configuration, and online upgrades. Each CAN and serial port supports four TCP or UDP sessions, supporting various operating modes including TCP Server, TCP Client, UDP Server, and UDP Client. It also supports web access. The included Windows-based management and configuration tool guides users step-by-step through device management and configuration, enabling serial devices to connect to the internet instantly through simple setup. The user-friendly network management system offers simple and easy operation, providing a superior user experience.

● Powered by an ARM Cortex-M4 processor with a 240MHz clock speed.

● Supports one 100M Ethernet channel; Ethernet supports 10/100Base-T(X) auto-sensing Ethernet interface, auto-negotiation (full and half duplex), and automatic crossover detection (MDI/MDIX).

● Supports multiple configuration methods, including web and Windows tool configuration, and SNMP network management.

● Provides one CAN bus channel, supporting 0-1Mbps line speed, non-blocking communication, automatic baud rate scanning and matching, and custom baud rates.

● Supports CAN 2.0A and CAN 2.0B frame formats, compliant with ISO/DIS 11898.

● Supports three CAN transmission modes: transparent conversion, transparent transmission with information, and relay. CAN’s maximum transmit data rate is 8000 frames per second; CAN-side message timestamp accuracy reaches 1µs.

● Provides one selectable RS232/422/485 serial port, supporting non-blocking communication at line speeds from 300bps to 921600bps, automatic baud rate scanning and matching, and custom baud rates.

● Each CAN and serial port features 6kV lightning protection and 3kV optical isolation. Each CAN channel has an independent shielded ground connection and is powered by a 3kV DC-DC power supply. Communication signals are isolated by high-speed optocouplers.

● Supports Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and other operating modes.

● Supports CAN status and CAN parameter monitoring for clear communication status.

● Supports serial port status and serial parameter monitoring for clear communication status.

● Supports communication across gateways and routers. Supports virtual serial port driver access mode and automatic connection recovery after network interruptions.

● Flexible serial port data framing settings meet various packet segmentation requirements.
