Input Cable Length Tuning
The HDMI5 features receiver equalization that can be used to com-
pensate for the losses that occur in var ying length, and var ying
quality, cables.
The HDMI5 allows for 15 levels of equalization. Using high quality
DVI or DVI to HDMI conversion cables, the HDMI5 can compensate
for cables of up to 65 feet (20 meters), on all its inputs and still
reliably receive a stable, spark le free image at 100p. Longer cable
lengths can be achieved at lower resolutions.
To tune an HDMI5's input to a specific cable length...
Step 1: Place the HDMI5 into the Cable Length Adj. Mode
Press the desired input and hold the button for seconds,
until the HDMI5 enters the Cable Length Adj. Mode.
Step 2: Enter the Cable Length Adj. Mode
Use the 'A1' and 'A2' buttons to tune cable length.
'A1' adjusts for shor ter cables.
'A2' adjusts for longer cables.
'SEL' switches to Bandwidth settings (See next page).
Shor t cables are indicate by only Red LEDs being lit.
Medium length cables are indicated by only Blue LEDs lit.
Long cables are indicated by Blue & Red LEDs being lit.
Use the Power Toggle button to exit the setup mode.
When a cable's tuning is too shor t, the display will begin to spar-
k le, eventually going blank . For best results, star t long, and use an
equalization a step or two above any noticeable ar tifacts on the
screen.
Note:
Output cable lengths depend on the display's receiver's
capabilities, and the quality of cabling used. The HDMI5
uses source termination to compensate for all lengths of
output cables, and to help in cases where the receiver
may not have followed the specifications properly.
Note:
Each input can be tuned individually andall settings are
saved in non-volatile memor y and are not affec ted by a
power failure.
