The Schneider Electric MTN6502-0101 is a SpaceLogic KNX USB interface for DIN-rail mounting. It provides a galvanically isolated link between a PC and the KNX bus for commissioning with ETS 4, 5, or 6 and higher.

The USB Type-C port (USB 2.0) supports KNX long-frame telegrams for faster application downloads and is compatible with KNX Security telegrams during secure device programming. The device is addressed locally; no on-board programming button is required. For network-based ETS access without a USB cable at the cabinet, use MTN6502-0105 IP interface or MTN6500-0103 IP router for multi-line routing.

Applications and KNX Integration

• On-site commissioning: Standard tool for installers programming lines fed by MTN684064.
• Secure projects: Commission MTN6705-0008S and MTN6215-0410S with KNX Security enabled.
• Multi-line sites: Use one USB interface per cabinet; route between areas with MTN6500-0103.
• Remote alternative: MTN6502-0105 for LAN/VPN tunneling without a physical USB connection.

Choosing USB vs IP Interface

Use MTN6502-0101 for direct PC-to-bus commissioning at the distribution board. Choose MTN6502-0105 when ETS must reach the bus over Ethernet (up to 8 tunneling channels). Choose MTN6500-0103 when inter-line IP routing is also required.
