Example of Determining Sink Support (FIG. 39):
FIG. 39 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 68). The remaining sources
were checked one at a time using the same method, and then the system was initialized using InstaGate
®
Technology
(see page 66) to route each source device to specific destination devices (up to the maximum each source supports).
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 HDMI UTPro.
Even though the connected source device may support more than 16 sinks, the HDMI UTPro only supports 16 sinks per
input. The HDMI UTPro will not allow the source device to route its signal to more than 16 sinks downstream of the
HDMI UTPro.
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 UTPro 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.
