NMEA 2000 T-connector, One Port

The Garmin NMEA 2000® T-connector is a critical component designed for extending marine network architectures. It allows any NMEA 2000-compatible device, such as sensors or displays, to connect to the main backbone of the network, ensuring seamless communication between onboard equipment.

This T-connector, part number 010-12935-10, features an optimized design where the connection port is offset by 45 degrees compared to previous iterations. This modification is intended to simplify installation in confined spaces aboard your vessel.

This connector uses NMEA 2000 micro-connectors, which are the standard for Garmin sensors and displays. It is compatible with other NMEA 2000-certified micro-connectors, cables, and devices, ensuring extended compatibility within an NMEA 2000 network.

Yes, the Garmin NMEA 2000® T-connector (part number 010-12935-10) is a revised and installation-optimized version, succeeding part number 010-11078-00.

In an NMEA 2000 network, the T-connector is a fundamental element for building a linear backbone. Each device (sensor, display, etc.) must connect to the main backbone via a T-connector, and this Garmin model provides a single port for this function.

A NMEA 2000 device must be connected to the top port (the single port) of a T-connector. The sides of the T-connector are reserved for connection to the main backbone of the network, either directly to another T-connector or via a backbone cable.

The 'backbone' is the main communication path of the NMEA 2000 network. It is a linear structure made up of T-connectors and backbone cables, and it must be terminated at both ends to ensure proper network operation. All NMEA 2000 devices connect to this backbone via T-connectors.

Yes, NMEA 2000 is a plug-and-play communication standard. It was designed to simplify the interconnection of marine devices, allowing sensors and displays to communicate easily with each other.

The NMEA 2000 network must be powered by a 12 Vdc direct current source. NMEA 2000 devices must operate between 9 and 16 Vdc, with a nominal voltage of 12 Vdc.

Yes, terminators must be installed. A 120-ohm terminator must be fitted at each end of the NMEA 2000 backbone. Proper termination is essential to maintain signal integrity across the entire backbone and ensure the network operates correctly.

An NMEA 2000 drop cable, which connects a NMEA 2000 device to the backbone, is limited to a maximum length of 6 meters (20 feet).

Yes, the dedicated NMEA 2000 power cable must connect to the top port (the single port) of a T-connector, not the side ports. The location of the T-connector for power depends on backbone length and device power requirements.

Yes, NMEA 2000 is a communication standard. The micro-connectors used by Garmin are compatible with other micro-connectors, cables, and devices certified as NMEA 2000, regardless of brand, as long as they comply with the NMEA 2000 standard.

NMEA 2000 is considered the successor to the NMEA 0183 serial data bus standard. It provides faster and more robust communication with a plug-and-play architecture.

This NMEA 2000 T-connector has a single port for connecting a device. It also has two additional ports for connecting to the network backbone.

Yes, you must connect each NMEA 2000 device to the main backbone of the network using a dedicated T-connector. This is a fundamental rule for building a correct NMEA 2000 network.

Yes, this T-connector is a key element for creating a NMEA 2000 backbone. By combining it with other T-connectors and backbone cables, you can build a network architecture suited to your vessel.

The T-connector itself does not provide power. It serves as a connection point for devices to draw power from the NMEA 2000 backbone, which is powered separately by a dedicated power cable connected to another T-connector.

For correct backbone construction, all T-connectors must be connected to each other via their sides, either directly or via a backbone cable. The top part of a T-connector must only be used to connect a device or the network power supply. The backbone must always be linear and terminated at both ends.

Yes, even if a NMEA 2000 device is very close to the backbone, it must always be connected via a T-connector. This is a requirement of the NMEA 2000 standard to maintain network integrity and structure.
