Advanced Control
To assign zone EDIDs to a source:
^ESET @
src
,0$
Use the default EDID for this source.
^ESET @
src
,
zmsk
$
Assign zone EDIDs to the source based on the bits in the setting.
^ESET @
src
,?$
Query for current setting
Response String:
^=ESET @
src
,
zmsk
$
Where:
src
=
The source number.
zmsk
= The zone assignment mask. If Bit-0 is set, then Zone1 will be assigned to the source, if
Bit-1 is set, the assign Zone2.
Example:
To assign zones 1 & 3 to source 4:
^ESET @4,5$
Bit0=Zone1, Bit2=Zone3. Setting bits ‘0’ and ‘2’ = ‘5’.
‘KSIZI’ Set the number of HDCP keys of a source
For HDMI to work properly, each monitor connected to the switch must be issued a key by each source
connected to the switch.
By default the switch simply assumes each source has enough keys to drive all the monitors attached to
the switch. But this is not always the case.
Some manufacturers supply a limit number of keys, sometime as small as 1 key. If a source has only 1
HDCP key, then only one monitor can negotiate an HDCP connection with the source. When a second
monitor is switch to the source, it will be unable to connect. In most cases, this will also break the
video connection to the working monitor as well.
This command allows you to specify the number of keys a source has. The HD1600V2 will then limit
the number of HDCP negotiations to the given number. All the monitors will still need to be authenti-
cated with the source, to allow proper HDCP operations, but the switch will limit the number of simul-
taneous negations to the number given by this command.
Once all the connected monitors are authenticated to the source, the HD1600V2 will generate the miss-
ing keys.
If you believe you are having a problem with HDCP keys, perform the steps outlined at: “
HDCP
Keys
” on page 19. 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.
