CEC Commands
Consumer Electronics Control (
CEC): Atlona has confirmed proper CEC functionality with several current models of
Samsung, Panasonic, and Sony displays. However, it is not guaranteed that CEC will work with all displays. Many
manufacturers do not support the CEC “off” command, and older displays use proprietary commands. Atlona only
supports displays that use the CEC command structure defined in HDMI 1.2a. It is recommended that dealers re
-
quest an evaluation product from Atlona, before designing a system using the CEC protocol. If this is not possible,
then other control methods will need to be considered, in order to control displays using Atlona products.

Click this drop-down list to select the desired pulse duration for the relay. Some devices may require different time
