HDMI CEC female to HDMI male adapter, black

The adapter has no connection at Pin 13 which can prevent problems when installing HDMI splitters and switches
When using the adapter, the CEC signal is not applied to the cable to the device.

Blocks HDMI CEC signals when there is an incompatibility.
Use this adapter when you have problems with incompatibilities between IR remote controls; such problems tend to occur now and then in installations with HDMI splitters and -switches.
The adapter does not pass on the CEC signal further. In principle, you only need to use this adapter upstream of the incompatible devices. However, several adapters installed upstream of a number of devices can be used.
