The Moxa CN2610-8 is a terminal server from the CN2600 series, specifically designed for industrial applications where reliable serial communication over IP networks is required. The device features eight serial ports designed for RS-232 interfaces and offers Dual-LAN functionality with two independent Ethernet ports, each having its own MAC and IP address. This configuration enables network redundancy, ensuring communication remains active even if one of the two LAN ports fails. The integrated Redundant COM function ensures the serial ports remain accessible even if a network path is unreachable. Additionally, the device optionally supports Dual-Host connections, increasing flexibility in network integration.

Applications

The CN2610-8 is designed for use in industrial environments, particularly in manufacturing, power supply, transportation, building automation, and infrastructure networks. In these areas, continuous and stable communication between serial devices and IP-based networks is essential. The robust construction with a metal housing and certifications according to UL, FCC, CISPR, IEC, and RoHS make the device suitable for demanding environments where high EMC requirements and safety standards apply.

Functions and Equipment in Detail

The device supports a variety of operating modes, including TCP/UDP, Real COM, Terminal, Reverse Telnet, RFC2217, PPP, and Redundant COM. Baud rates can be set between 50 bps and 921.6 kbps, with flexible configuration options for data, stop, and parity bits (5–8 data bits, 1/1.5/2 stop bits, None/Even/Odd/Parity). Flow control options include RTS/CTS, XON/XOFF, and DTR/DSR, enabling communication with various serial end devices. The serial ports are equipped with 1.5 kV isolation, ensuring high electrical safety.

Technology Explained Simply

The Dual-LAN functionality means that two separate Ethernet connections can be operated in parallel, each with its own network configuration. This increases device availability, as one connection continues to function if the other fails. The Redundant COM function allows the serial ports to remain accessible even if a network path is unreachable, automatically switching to the remaining path. Power supply is via Dual-AC inputs, providing additional operational safety in case of power failure, although the CN2610-8 model is not explicitly marked as a Dual-AC model.

Compatibility and Accessories

The terminal server is compatible with common operating systems, including Windows, Linux, macOS, various UNIX variants, and Android from version 3.1. Driver types include Real COM, TTY, and API (for Android), enabling broad integration into various system environments. Management is performed via a web console, a Windows utility, or Telnet. Security features include encryption with AES-128/256, RSA-1024, HMAC, and HTTPS, as well as authentication via local database or RADIUS. Protocols SNMPv3, SSHv2, and MIB-II support network management and monitoring.

Mounting and Installation

The device is designed for mounting in a 48,3 cm ( 19 inch ) rack and is delivered with a rack mounting kit. Installation is performed using an RJ45-to-DB9 console cable and one or two network cables, both included in the delivery. A Quick Installation Guide supports setup. The operating temperature ranges from -40 °C to 85 °C, making the device suitable for use in extreme environments. The MTBF is up to 831,925 hours, indicating high reliability and longevity.

Operational Advantages

The combination of Dual-LAN, Redundant COM, and optional Dual-Host support ensures high availability of serial communication. The robust construction, wide temperature tolerance, and international standard certifications make the device a reliable solution for demanding industrial applications. Easy management via web console, Windows utility, or Telnet, along with support for many operating systems, increases flexibility and maintainability.
