Lowrance 000-0119-79 N2K-T-RD NMEA 2000 T-Connector

Lowrance 000-0119-79 N2K-T-RD — NMEA 2000 T-Connector

The Lowrance N2K-T-RD is a standard NMEA 2000 T-connector that allows you to branch a device off the main network backbone while keeping the backbone run continuous. It features the industry-standard Micro-C connector format and is compatible with any NMEA 2000 compliant network, regardless of brand.

Part Details

• Part Number: 000-0119-79
• Brand: Lowrance
• Official Product Type: NMEA 2000 T-Connector
• Connector Style: Micro-C (NMEA 2000 standard) — inline T, male backbone in / female backbone out / female device drop
• Color: Red (RD designation)
• System: NMEA 2000 marine networking
• Weight: 34 g

Compatible Applications

• Adding a device drop to an existing NMEA 2000 backbone run
• Expanding a Lowrance, Simrad, Garmin, or any NMEA 2000 Micro-C compatible network
• Helm installations requiring a branch point for a display, sensor, or instrument
• New NMEA 2000 network builds alongside backbone cable and terminators

Parts Desk Insights

Best Use Case: This T-connector is the core building block of any NMEA 2000 network expansion. You need one T-connector for every device you want to connect to the backbone — whether that's a chartplotter, VHF radio, engine interface, or sensor. It's also the right choice when adding a single new device to an existing working network: simply insert the T into the backbone at the nearest convenient point and run a drop cable to your device.

Common Issues: The most common mistake is confusing the backbone ports with the device drop port — the single female port is the device drop; the two inline ports continue the backbone. Also confirm your backbone is properly terminated at both ends with male terminators before powering the network. If you're starting a new network from scratch, consider the X2K-Exp-Red-2 NMEA Starter Kit, which includes T-connectors, backbone cable, terminators, and a power cable in one package.

Technical Notes

• One T-connector is required per network device
• The NMEA 2000 backbone must be terminated at both ends with a 120-ohm male terminator for correct network operation
• Maximum backbone length: 100 m (standard NMEA 2000 specification)
• Maximum drop cable length per device: 6 m
• Maximum number of devices on a single backbone: 50 nodes
