Frequently Asked Questions
What is a dual-LAN terminal server used for?
A dual-LAN terminal server converts serial RS-232/422/485 connections to Ethernet, enabling legacy industrial devices to communicate over modern networks. The dual Ethernet ports provide redundancy, ensuring continuous connectivity even if one network link fails.
Why is 2 kV optical isolation important?
Optical isolation protects connected equipment from electrical surges, ground loops, and noise interference common in industrial environments. The 2 kV rating ensures robust protection for sensitive serial devices and prevents damage from power transients.
Can the CN2650I-16-2AC support mixed serial protocols?
Yes, the 16 RS-232/422/485 ports are configurable, allowing simultaneous support for different serial protocols. This flexibility makes it ideal for integrating diverse legacy equipment in unified industrial networks.
What are the benefits of dual AC power inputs?
Dual AC power inputs eliminate single points of failure, ensuring the terminal server remains operational during power supply maintenance or failure. This redundancy is critical for mission-critical industrial automation and remote monitoring applications.
