780C Multi-Interface Interoperability Tester – User Guide Page 126September 29, 2014 Revision A16.5 Testing an HDMI or HDBaseT Source’s Response to EDIDsThe 780C HDMI and HDBaseT IN ports emulate an HDMI or HDBaseT sink device. Part of that emulationfunction is presenting an EDID to a source when a sink device is powered and hot plug is asserted. The 780Cis provisioned with a default EDID from the factory. There are two standard EDIDs available with the 780C asprovided: 1) Standard HDTV EDID, 2) Standard A/V Receiver EDID.However you can reprovision the EDID by connecting it to a sink device whose EDID you would like to use fortesting. The 780C can store multiple EDIDs. These EDIDs can be obtained either by extracting them from anHDMI or HDBaseT sink device (e.g. HDTV, Projector, AVR, repeater or distribution device input) or byimporting EDID .xml files created using Quantum Data EDID Editor tools. For procedures on importing EDIDsrefer to Adding Reference EDIDs for Use in Testing HDMI Devices.Note: Quantum Data has an EDID Library available for free at: http://www.quantumdata.com/edid/.The EDID test of an HDMI or HDBaseT source device enables you to see how a source device responds to aspecific EDID or a series of EDIDs. The EDID could be a known good EDID or an EDID you have chosenspecifically for testing purposes.6.5.1 Configurations for Testing an HDMI Source Devices Response to an EDIDYou can run this test in two configurations: 1) with your source device connected directly to the 780C, 2) withyour source device connected to the 780C through a repeater device. In both cases the 780C is emulating anHDMI sink to test an upstream source. These configurations are shown below.6.5.2 Configurations for Testing an HDBaseT Device’s Output Response to an EDIDTypically you run this test with the 780C connected to an HDMI source through an HDBaseT distributiondevice. This configurations is shown below.
