HDMI Control Settings

HDMI control settings. These commands change the behavior of the HDMI switch. The changes made
will only be in affect until the switch is powered down. To make this changes permanent, be sure to
save these settings in EEPROM after making all desired changes.
These settings are saved using the 'SS' command. (See: "'SS' Save Default Power On Settings" on
page 55)

'EDLO' EDID Lock

Locking the EDID will keep the HDMI switch from registering any new EDID changes. Any new
devices added to the switch, or any devices removed from the switch will be ignored.
This command is useful in keeping a receiver from causing the switch to re-read EDIDs and HDCP
keys each time the receiver is power cycled. This will cause displays to flicker.
Most receivers will change their EDID settings when their power state is changed. They will change
the EDID to indicate their own built in capabilities when turned on. When turned off they will either
remove the EDID completely or pass through the EDID of the monitor plugged into the receiver's out-
put.
The Zektor Switch switch sees this change in EDIDs as a change in devices, which forces it to re-nego-
tiate the new devices with the sources HDCP keys. This will cause a temporarily loss of video on
zones sharing the source that's having it's HDCP keys read.
To prevent display flickering each time a receiver is turned on or off, you should perform the proce-
dure titled: Validating the Installation" in the user guide.
Once your system is validated, you should lock the EDID, and then save the new HDMI settings in
EEPROM so that they won't be lost when power is cycled. (See: "'SS' Save Default Power On Set-
tings" on page 55)
To turn on / off, or the EDID lock state of the Zektor Switch:
^EDLO 0$
^EDLO 1$
^EDLO ?$
Response String:
^=EDLO n$
Where:
= Current lock state, 0=Unlocked, 1=Locked.

'ESET' Assign zones to an input source

By default, all the EDIDs of all zones (monitors and receivers) are read, and the lowest common fea-
tures of all the zones are combined into a single EDID, that is sent to all the sources. For instance, if all
the zones can receive Dolby5.1 audio, then the EDID will indicate that Dolby5.1 can be sent. If how-
ever even a single TV can only decode PCM stereo, the combined EDID will indicate to the all the
sources that only PCM stereo can be sent to any zone.
You can use the 'ESET' command to combine the EDIDs of similar devices and send the combined
EDID to a source that will be associated with the devices. For instance all receivers can be combined
and sent to a Blu-ray or Cable box that will be used mostly for those receivers. This allows you to
enable Dolby5.1, or Dolby TrueHD, or any other features the receivers are capable of decoding.
