Example of Determining Sink Support (FIG. 46):
FIG. 46 illustrates a source device that was checked and found to support only 5 sinks past R1. The check
included the following: From a clear matrix state (the cache is clear), the source device was routed to
Outputs 1, 2, 3, 4, and 5 one at a time as a stable image appeared on each destination device. When
attempting to route the source device to the sixth output, all displays lost content. Only five of the
destination devices will be able to receive a signal from this source. At this point, the limitation of the
source device was noted and the cache cleared (see page 82). The remaining sources were checked one
at a time using the same method, and then the system was initialized using InstaGate
(see page 81) to route each source device to specific destination devices (up to the maximum each source
supports).

Determining sink support
The previous process works for verifying sink support for a source device up to 8 sinks. If the process
did not cover the needs of the installation (extra repeaters, etc.), continue with the next one until full
system capabilities are mapped out.
The next process works for determining if additional sinks are supported by the source device up to a
maximum of 16 downstream of the Optima.
Even though the connected source device may support more than 16 sinks, the Optima HDMI board only
supports 16 sinks per input. The Optima board will not allow the source device to route its signal to more
than 16 sinks downstream of the Optima.
To determine sink support maximum from 8 up to 16 on a source device:
1. If not already completed, complete the previous instructions.
2.
Disconnect the first destination device from the HDMI board and connect a new destination device
in its place (this increases the total number of sink devices by one). (Alternatively, attach an HDCP
supported repeater to the output, and attach the repeater to the same destination device.)
3.
Repeat Step 2 for the remaining outputs until either all 8 destination devices show the image from
the source or a failure point is reached.
