Moxa CN2650I-8 Terminal server DB9 connector

The CN2600 Series terminal servers by Moxa deliver highly reliable serial-to-Ethernet communications with comprehensive redundancy features and flexible interfacing. Designed for industrial applications where uninterrupted data transfer is critical, these devices offer 8 or 16 serial ports (RS-232/422/485), dual-LAN and dual-AC input models, and robust protocol support for seamless integration into Ethernet networks.

A highlight is the Redundant COM mode, which sends identical data simultaneously over two LAN interfaces, ensuring that no data is lost even if one network path fails. The dual-host redundancy allows two hosts to be connected independently—providing system-level resilience in mission-critical applications.

User-friendly with configuration options via web console, Telnet, or serial console, these devices also feature a built-in watchdog timer (WDT), real-time clock (RTC), and buzzer alert system. Rugged metal housing, 19-inch rack mount design, and models built for wide temperature ranges or high-voltage DC supply make the CN2600 Series well-suited for harsh industrial environments.
