The Schneider Electric MTN6500-0103 is a SpaceLogic KNX IP router for DIN-rail mounting. It forwards telegrams between KNX twisted-pair lines over a LAN (KNXnet/IP), forming a high-speed IP backbone and providing up to eight ETS tunneling channels for programming and visualisation.

The router supports KNX IP Secure and KNX Data Secure, coupling secured and non-secured TP segments onto a protected IP network. An extended filter table (main groups 0–31) and internal buffer (150 telegrams) manage bus load. Power is drawn from the KNX bus (≈ 12 mA); supply the line with MTN684064 or MTN6513-1202. For TP-only line coupling without IP, use MTN6500-0101; for bus programming without routing, use MTN6502-0105.

Key Features — Secure IP Backbone

Routing and Tunneling

• KNXnet/IP: Core, device management, tunneling, and routing per KNX specification.
• Tunneling: Up to 8 simultaneous channels for ETS, visualisation, or logic servers.
• Filter table: Extended — main groups 0–31 (ETS-generated).
• KNX Security: IP Secure backbone; forwards secured and unsecured telegrams.
• IP addressing: DHCP or manual configuration via ETS.

Commissioning and Diagnostics

• Front-panel test: Two push-buttons for commissioning tests.
• Status LEDs: Power and communication indication (3 LEDs).
• ETS application: IP Router secure 7127/1.2 — ETS 5.7.3 or higher.
• Factory default address: 15.15.0.

Applications and KNX Integration

• IP backbone: Replace multiple TP couplers with LAN routing between areas — pair with LSS100200 or LSS100100 on the network.
• Remote ETS: Tunnel programming sessions over VPN without a USB interface at each cabinet.
• Multi-line buildings: Route between sub-lines fed by MTN6500-0101 couplers on each TP segment.
• Secure projects: Deploy KNX IP Secure on the backbone; extend secure switching with MTN6705-0008S on field lines.
• Load monitoring: Meter circuits on routed lines with MTN6600-0603.

Choosing IP Router vs Coupler vs IP Interface

Use MTN6500-0103 when you need routing and filtering between KNX lines over IP. Choose MTN6500-0101 for TP-to-TP coupling only. Choose MTN6502-0105 when you only need ETS tunneling to one line without inter-area routing.
