Dealing with Sources with Limited Sink Support
For sources with limited sink support, the following system design considerations and control
suggestions are provided.
System Design Considerations
If at all possible, replace the source device with one with that supports more sinks.
If a repeater is connected between the source and the HDMI board and the repeater is not
necessary, remove the repeater and connect the source device directly to the Optima input.
The Optima becomes the first repeater and one sink is eliminated, allowing you to add one
more destination to the system.
If a repeater is connected between the HDMI board and a display device and the repeater is
not necessary, remove the repeater and connect the display device directly to the Optima
output. This eliminates the one sink, allowing you to add one more destination to the system.
Example of Reducing Sinks:
A reduction in sinks can be made by removing unnecessary repeaters either upstream or downstream of
the Optima.
If a source supports five sinks downstream of the first repeater and the sinks (repeaters and destination
devices) total six, removing a repeater will reduce the number to five. In this example, the source will
not transmit the protected content until the number of sinks is reduced to five or less.
Important: If the repeater that is removed is downstream of the Optima, you will need to clear the
Optima input’s sink key cache and then persist the cleared state to eliminate the key(s) before
routing the source to any of the destinations; for instructions, see page 85.
Control Suggestions
Either a controller or a modified configuration file can provide a workaround for sources with limited
sink support.
Program an external controller so that the source(s) can only be routed to a limited number of
specific destination devices.
Use XNConnect to create a virtual matrix (VM) that limits routing of the source(s) to a limited
number of specific destination devices (see the next page).
External Controller
For control programming information for an Optima using an external controller, see the external
controller’s documentation.
Tip: Locking the control panel after routing the desired sources can prevent accidental switching
of a source to more sinks than it supports and the resulting need to empty the cache and go through
the initial authorization process again. For locking instructions, see the control panel documentation.
XNConnect
XNConnect can be used to create virtual matrices (VMs) which limit the routing of a source to specific
destinations.
Caution: Virtual matrix modifications are an advanced feature of XNConnect that should not be
attempted unless you are extremely familiar with XNConnect and the AMX Distribution Matrix being
configured.
