to the HDMI/CEC output port on the receiver. If the device (such as a CEC-compliant
display) supports CEC control, the HCR 102 can automatically turn display power on or
off based on whether an active signal is detected at the selected input.
NOTE: It can take up to 2 minutes after powering up the receiver to initiate CEC
display control.
Via PCS, this port can be configured for DVI output or for one of several HDMI formats.
You can select an HDCP output mode, and configure scaling settings to match video
resolution and rate for the display device. To facilitate setup, the receiver can output a
test pattern via this port,
or it can display the
on-screen menu options
(see Using the OSD
Menu System on
page 41) for use
during configuration.
About CEC control
Consumer Electronics Control (CEC) is an industry standard for control functions provided
by HDMI. CEC control functions are incorporated into the HCR 102 and into GC software
to control other equipment. HDMI CEC implementations vary by manufacturer and by their
equipment.
Extron has tested a representative sample of equipment from other manufacturers to assure
that power on and off commands work with most devices that conform to the HDMI CEC
standard. However, CEC interoperation between the HCR 102 and equipment from other
manufacturers cannot be guaranteed. Volume and audio mute commands may or may
not be supported by any given display. See the manual for the device that you want the
HCR 102 to control to determine the details of the HDMI CEC functions for that product,
and see the release notes for the Extron Universal Display Driver - HDMI CEC.
TIPS:
If your display device does not support CEC commands or does not support a
•
full implementation of them, use one of the other control options available in the
HCR 102, such as RS-232, IR, or Ethernet control.
Some displays must be configured to enable CEC communication.
•
Automatic display power control
The HCR 102 can automatically turn display power on or off based on whether an active
signal is detected at any input. The system uses CEC driver commands sent to the display
to automatically turn display power on or off based on whether or not an active signal is
detected at any input.
• When an active signal is detected at any input, the receiver automatically sends the
CEC power-on command out the HDMI/CEC port to the display or projector.
• If no signal is detected at all inputs, the receiver sends the CEC power-off command to
the display or projector.
HC 400 Series systems ship with basic CEC control built into the default configuration.
Basic CEC controls in that configuration work "out of the box", but can be further
customized using Global Configurator software.
The CEC port configuration can specify whether or when to send the power-off command,
change the timeout period (from 0 to 500 seconds), and specify whether to send other CEC
commands. See the Global Configurator Help File for more detailed information on the port
and on macros.
