ClarityHD8x8 Serial Protocol, Version 1.1, 6/7/13 29
Advanced Control
Once all the connected monitors are authenticated to the source, the ClarityHD8x8 will generate the
missing keys.
If you believe you are having a problem with HDCP keys, perform the steps outlined at: “HDCP
Keys” on page 18. If it appears you have a source with a limited amount of keys, use this command to
limit the number of keys sent to the source.
To turn on / off, or the EDID lock state of the ClarityHD8x8:
^KSIZI 0$ Sets the switch to the normal mode of operating where key limits are not checked.
^KSIZI n$ Sets the HDCP key limit to ‘n’ (n = 1 - 23).
^KSIZI ?$ Query for current setting
Response String:
^=KSIZI n$
Where:
n = Number of keys available in source. 0 = Key limits are not checked, 1-23 = Limit the number
of HDCP keys to ‘n’.
This setting is lost when power is cycled on the ClarityHD8x8. To save this settings through a power
cycle, backup the HDMI settings using the ‘SS’ command. (See “‘SS’ Save Default Power On Set-
tings” on page 25.)
