Industrial Video Ethernet Switch 4x100M Ethernet 1 Video 1 RS485 1 Gigabit Fiber
The LNK-GY4E1V1D Industrial Video Ethernet Switch is a rugged, physically isolated networking solution designed for harsh industrial environments. It integrates 4×10/100M Ethernet ports, 1×Video interface, 1×RS485 serial data port, and 1×Gigabit fiber uplink, making it ideal for multi-protocol industrial networks.
✅ Multi-Protocol Industrial Connectivity
4× Physically Isolated 10/100M Ethernet Ports: Ensures secure, independent network segments for internal & public networks.
1× Video Interface: Supports CCTV/IP camera integration for surveillance networks.
1× RS485 Serial Port: Enables PLC/SCADA device communication (MODBUS RTU, PROFIBUS).
1× Gigabit Fiber Uplink (1000BASE-X): Extends long-distance fiber backhaul (up to 120km).
✅ Industrial-Grade Reliability
Physical Isolation Technology: Prevents cross-network interference for mission-critical systems.
Wide Temperature Range (-40°C to 75°C): Operates in extreme outdoor/industrial conditions.
IP40 Metal Housing: Resists dust, vibration, and EMI interference.
✅ Flexible Deployment
DSLAM Bandwidth Expansion: Upgrades legacy fiber networks without rewiring.
Multi-Network Isolation: Ideal for secure OT/IT network convergence.
Plug-and-Play Installation: No complex configuration required.
1536 Bytes Jumbo Frame Support: Optimizes throughput for video & large data packets
1MB Built-in Frame Buffer: Prevents packet loss during high-traffic bursts
Auto-Select Switching Modes: Store-and-Forward (error checking) or Cut-Through (low latency <5μs)
4×10/100M Auto-Negotiation Ports: Support Full/Half-Duplex & Auto-MDI/MDIX for plug-and-play cabling
1024 MAC Address Table: Enables automatic learning/updating for large-scale device networks
Video Interface: Directly connects CCTV/ANPR cameras without extra converters
6KV Lightning & Surge Protection: Safeguards against power surges in outdoor installations
Dual 12-48VDC Power Inputs: Ensures 24/7 uptime with redundant PSU support
Wide Temp Range (-40°C to 85°C): Operates in extreme environments (factories, tunnels, substations)
DSLAM Bandwidth Expansion: Upgrades legacy fiber networks without cable replacement
LED Port Status Indicators: Real-time monitoring of link/activity/speed per port
DIN-Rail/Wall-Mount (IP40): Compact metal housing for space-constrained cabinets
