Cause/Check item/Solution
Ensure that the registered control command data and the number of bytes
are both correct. Devices requiring delimiters may not execute commands
correctly if the delimiters are not sent. If the set number of bytes is not
correct, the control command may not be sent completely or unnecessary
data may follow the control command.
Is the registered control command correctly linked to the desired control
command execution condition?
Is COM PORT's FUNCTION set to "RECIEVER" mode?
In order to send control commands, the communication port must be
configured for "TRANSMITTER" mode.
If using LAN, set the IP address and other com port settings of the
connected device.
Is the registered reply command correct?
Ensure that the setting of "TIME OUT" for checking control commands is
not too short.
Does the cable support CEC?
In order to use CEC, use an HDMI cable that supports CEC.
Does the sink device support CEC?
Is the HDMI link function of the sink device set to be enabled?
Enable the HDMI link control of the sink device and the function which
powers on the sink device from external devices of the sink device.
When the CEC connection changes, EDID may also change. In this case,
the input signal may be interrupted. Check the CEC connection settings.
Are HDMI cables that support CEC being used?
To use CEC, enable the HDMI link control of the connected devices (such
as LCD TVs, Blu-ray recorder, and other formats).
