connected. (Fig 4.)
Short: With three short “beep” sound. Shorted pins
LED will light up at same time. Example: Test HDMI
(A Type) to HDMI (A Type) cable that pin #4、#5、#6
are shorted or test HDMI (A Type) to Mini-HDMI
(C Type) cable that pin #4、#5、#6 are shorted. (Fig 5.)
Crossover: With two short “beep” sound. Crossed
pins LED will light on at same time. Example: Test HDMI
(A Type) to HDMI (A Type) cable that pin #13 crossed
with pin #17 and pin #14 crossed with pin #19, or test
HDMI A Type) to Mini-HDMI (C Type) cable that pin
#14 crossed with pin #13 and pin #17 crossed with
pin #19. (Fig 6.)
