Zektor Switch Serial Protocol, Version 0.16, 5/13/16

Advanced Control

need to be authenticated with the source, to allow proper HDCP operations, but the switch will limit
the number of simultaneous negations to the number given by this command.

Once all the connected monitors are authenticated to the source, the Zektor Switch will generate the
missing keys.

If you believe you are having a problem with HDCP keys, perform the steps titled: “HDCP Keys” in
the user guide. 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 set the number of keys of a source:

^KSIZI @

src

,0$

Sets the switch to the normal mode, where key limits are not checked.

^KSIZI @

src

,n$

Sets the HDCP key limit to ‘n’ (n = 1 - 23).

^KSIZI @

src

,?$

Query for current setting

Response String:

^=KSIZI @

src

,

n

$

Where:

src

=

The source number.

n

=

Number of keys available in source. 0 = Key limits are not checked, 1-23 = Limit the num-

ber of HDCP keys to ‘n’.

This setting is lost when power is cycled on the Zektor Switch. 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 55.)
