Identify Ancor NMEA 2000 Parts

When sorting NMEA 2000 marine-network parts, first distinguish network power, backbone, and device drop. Ancor marks these connection types differently. A yellow-coupler backbone cable is not the same component as a black-coupler drop cable, even if their lengths look alike.

Recognize the component's job

Red connector: network power

The 270000 is a 1-metre power cable supplied with a tee. It is not the cable used to link two electronics displays.

Yellow connector: backbone

270001, 270002, 270005 and 270010 are backbone sections of different lengths. Read the label and measure the cable.

Tee connectors: branch points

270101 is a single tee and 270103 is a two-way tee. Check the number and arrangement of available connections.

Black connector: device drop

The 270302 is a 2-metre drop cable, used between a compatible electronic device and its backbone tee.

Part number, type and measured length

MPN	Component	Length	What it does
270000	Power cable with tee	1 m (3.3 ft)	Red-coded power tee that introduces network power
270001	Backbone cable	0.5 m (1.6 ft)	Short yellow-coupler backbone section
270002	Backbone cable	2 m (6.5 ft)	Yellow-coupler backbone section
270005	Backbone cable	5 m (16 ft)	Longer yellow-coupler backbone section
270010	Backbone cable	10 m (32 ft)	Longest backbone length in this comparison
270101	Single tee connector	Connector	One tee connection for a device drop
270103	Two-way tee connector	Connector	Two drop-cable connections from one tee assembly
270302	Drop cable	2 m (6.5 ft)	Black-coupler cable between a device and a tee

What to examine before reusing a part

Read the six-digit Ancor part number and compare with the table, particularly when the same-looking cable is available in several lengths.
Identify the coupler colour and the connection role. Avoid treating yellow backbone cables as device drops.
Inspect pins, threads, seals, housing and the cable jacket for damage; check whether any terminators or blanking caps are supplied separately.
Check the existing network topology and the equipment requirements before connecting a component. A tee is not a terminator.
Review the individual store listing for condition and availability; manufacturer identification does not establish the condition of an individual item.

For a standard NMEA 2000 network, Ancor specifies end termination with one male 270106 and one female 270105 terminator. These are separate items, not assumed to be included with the cables shown. Viewing and pickup at UsedRVParts in Kelowna are by appointment.
