FRL Signal Cable Test
5V: Checks for the presence of 5 Volts on pin 18 of the HDMI cable. There are two possible re
-
sults.
·
OK - 5V is present and the HDMI test will continue.
·
FAIL - No 5V is detected and the rest of the test will fail.
DATA CH: This will show the total number of Errors detected in the Audio Video data channels.
Ideally the test result should be zero (0) errors. The test is looking for any differences between the
pixels of a static image sent from the generator to the analyzer. Errors may not be noticeable when
viewing content, but if any errors are detected you may consider replacing that cable.
NOTE: If you install an HDMI cable that shows errors on the Data Channel we cannot guarantee
that the cable will work or perform as intended.
DDC (Display Data Channel): This test will verify that essential HDMI protocol signals such as EDID
or HDCP are present. There are two possible results.
·
OK
·
FAIL - Recommend replacing the HDMI cable.
HPD (Hot Plug Detect): This test will check for communications over the HDMI cable on pin 19
between the generator and analyzer. There are two possible results.
·
OK
·
FAIL - Recommend replacing the HDMI cable.
