6th/7th/8th Gen Cable Harness for NUC HDMI-CEC Adapter

Modified on Fri, 5 Jun at 11:38 PM

This article describes the cable harness supplied with the Intel NUC HDMI-CEC Adapter for 6th, 7th, and 8th generation Intel NUC systems. It covers the harness layout and how to connect each sub-connector to the correct header on your NUC motherboard.

Note: This harness is specific to 6th/7th/8th gen Skylake, Kaby Lake, and Coffee Lake NUC boards. If you have a 4th or 5th gen NUC, refer to the relevant cable harness article for your generation. For Skull Canyon or Hades Canyon NUCs, the adapter connects directly without a harness.

The Harness

The harness has a single base connector that plugs into the CEC adapter PCB, splitting into two 4-pin sub-connectors that each connect to a different header on the NUC motherboard.

The 6th/7th/8th gen cable harness. Left sub-connector goes to the USB header (X). Right sub-connector goes to the CEC header (P or N).


Connecting the Harness

Both sub-connectors connect to headers on the top side of the NUC motherboard. You do not need to remove the motherboard from the chassis to connect them.

Left sub-connector — USB header (marked X)

The left sub-connector plugs into the internal USB 2.0 header on the motherboard, which is labelled X on the board silk-screen. This header provides the USB data connection the adapter uses to communicate with the host system.

1
Locate header X on the motherboardWith the NUC lid removed, find the small 1.25mm pitch header labelled X. It is located on the top side of the board, typically near the memory slots.
2
Connect the left sub-connectorPress the left sub-connector firmly onto header X. The connector is keyed and will only seat correctly in one orientation.

Right sub-connector — CEC header (marked P or N)

The right sub-connector carries the CEC signal, 5V standby, and power switch. It plugs into the dedicated CEC header on the motherboard, labelled P or N depending on the board revision.

P or N — either works: Both the P and N headers are internal USB interface connectors and are functionally equivalent for this adapter. Plug into whichever is more accessible. You do not need to use a specific one.

The CEC header pinout (Molex 53398-0471, 1.25mm pitch, 4 circuits) as documented in Intel's NUC Technical Product Specifications:

1
Locate header P or N on the motherboardFind the small 4-pin 1.25mm pitch header labelled P or N on the top side of the board, typically near the HDMI output circuitry.
2
Connect the right sub-connectorPress the right sub-connector firmly onto header P or N. Check the small triangle or dot on the connector housing to align pin 1 with pin 1 on the header.

PCB Placement

Once both sub-connectors are seated, fix the CEC adapter PCB inside the chassis using the supplied double-sided foam pad. The recommended location is between the WiFi mPCI board and the memory modules, but any stable position that does not obstruct airflow or press against other components is acceptable.
