The Moxa NPort S8000 Series combines a 4-port RS-232/422/485 serial device server with a full-featured managed Ethernet switch. Designed for space-constrained industrial environments, it simplifies installation, reduces wiring complexity, and enhances network reliability through redundant networking technologies.

Key Features:

• 4 serial ports (RS-232/422/485)
• Integrated managed Ethernet switch: 5 copper or 3 copper + 2 fiber ports
• Serial QoS for prioritizing serial data traffic
• Ethernet redundancy: Turbo Ring, Turbo Chain (< 20 ms), RSTP/STP
• VLAN, QoS, IGMP snooping, LACP, SNMPv1/2c/3, RMON
• 2 kV isolation for serial signals
• Adjustable pull-up/down resistors and 120-ohm terminator for RS-485
• Surge protection for serial, Ethernet, and power inputs
