The Schneider Electric MTN6502-0105 is a SpaceLogic KNX IP interface that bridges a LAN (RJ45) and the KNX bus. It enables ETS programming, diagnostics, and visualisation access from any network point — including VPN remote sessions — without a USB cable at the cabinet.

Up to eight simultaneous tunneling channels support multiple ETS users or servers. KNX IP Secure encrypts tunnel traffic. The device is bus-powered (≈ 20 mA) from the KNX line; size the PSU with MTN684064 or MTN6513-1202. For inter-line routing over IP, use MTN6500-0103; for direct USB commissioning, use MTN6502-0101. ETS application 7133/1.0.

Key Features — Secure IP Tunneling

Networking

• Tunneling: Up to 8 simultaneous channels (ETS, visualisation, logic).
• KNX IP Secure: Encrypted tunneling over LAN/VPN.
• Remote access: Commission and maintain installations over VPN.
• IP configuration: DHCP or manual addressing via ETS.

Commissioning and Diagnostics

• Front panel: 2× push-buttons for tunnel channel selection; 3× status LEDs.
• ETS application: IP Interface 7133/1.0 — ETS 5 or higher.
• Compact: 1 DIN module (18 mm) — bus-powered, no external PSU.

Applications and KNX Integration

• Remote ETS: Program lines from the office via VPN — pair with logic servers LSS100100 / LSS100200 on the same LAN.
• Multi-user commissioning: Eight tunnel channels for parallel ETS and test tools.
• Secure buildings: Tunnel securely to MTN6705-0008S and MTN6215-0410S lines.
• Single-line access: When routing between areas is not needed — unlike MTN6500-0103 IP router.
• On-site USB fallback: Keep MTN6502-0101 for local commissioning if the network is unavailable.

Choosing IP Interface vs IP Router vs USB

Use MTN6502-0105 for ETS tunneling only to one KNX line over IP. Choose MTN6500-0103 when telegrams must be routed and filtered between multiple lines over IP. Choose MTN6502-0101 for direct USB connection at the cabinet.
