7.2 Diagnosing HDMI and HDBaseT Interoperability Problems at the Sink -
Downstream
This subsection describes how to diagnose HDMI and HDBaseT interoperability problems on HDMI or
HDBaseT sink device—downstream (Sink Test).
7.2.1 Connection Configurations for Testing HDMI Sink Devices
The 780C’s HDMI input port acts as a “reference” HDMI source device. Therefore it enables you to emulate a
known good HDMI source device to conduct diagnostics downstream toward the sink device. The following
illustrations show the typical configurations.
7.2.2 Connection Configurations for Testing HDBaseT Sink Devices
The 780C’s HDBaseT output port acts as a “reference” HDBaseT source device. Therefore it enables you to
emulate a known good HDBaseT source device to conduct diagnostics downstream toward the sink device.
The following illustrations show the typical configurations.
