The Moxa NPort 6400/6600 Series is designed to securely and efficiently connect up to 32 serial devices to an Ethernet network. Supporting RS-232/422/485 interfaces and encrypted communication via TLS and SSH, this series is ideal for industrial deployments requiring high flexibility, secure data transmission, and robust failover mechanisms.

Each port is independently configurable, enabling mixed-use environments. With a built-in 64 KB port buffer (expandable via SD card), the NPort ensures zero data loss during temporary network outages. The built-in LCD (standard models only) simplifies configuration and provides real-time status feedback.

Key Features:

• Terminal server with 4, 8, 16, or 32 serial ports
• Supports RS-232/422/485 (per-port selectable)
• Security: AES-128/256, HTTPS, SSHv2, SNMPv3, IEC 62443 compliant
• Fail-safe design with 64 KB per-port buffer + SD slot (up to 32 GB)
• LCD screen for quick setup (standard temperature models only)
• Ethernet redundancy via STP, RSTP, and Turbo Ring
• Supports Windows, Linux, macOS, Android, VMs, and embedded OS
