7 Using the 780 Test Instrument Installer Utility
This section provides procedures for diagnosing HDMI networks using the automated Installer Utility. The features and
functions described in this section are included as a standard feature. The Installer Utility enables you to quickly
and simply identify common interoperability problems. The Installer Utility enables you to conduct step by step
diagnostics toward the source—upstream (Source Test), toward the sink—downstream (Sink Test), or in a looped
configuration around a repeater device (Repeater Test). You can also conduct both and upstream and a downstream
diagnostic test at the same time using the Link Test.
Table 7-1 below describes what items are tested with each test in the Installer Utility.
