The Moxa CN2650I-8-2AC is a rugged industrial terminal server designed for mission-critical applications requiring high reliability. With 8 serial ports supporting RS-232/422/485 and 2 kV isolation on DB9 connectors, it offers excellent protection and communication performance in harsh environments.

Equipped with dual LAN ports and dual AC power inputs, this model delivers full network and power redundancy. Its Redundant COM mode ensures continuous operation by transmitting duplicate data over both LAN connections, making it ideal for fault-tolerant architectures in factory automation, utilities, and transportation.

Configuration is straightforward via web browser, Telnet, serial console, or Windows utilities. The server supports a broad range of operating systems and protocols, including modern security standards like HTTPS, SSH, and SNMPv3—ensuring secure and flexible integration into any industrial Ethernet network.
