DVI 101 and HDMI 101 • Installation and Operation 2-9
C When you are connecting the power supply, voltage
polarity is extremely important. Applying power
with incorrect voltage polarity could damage
the power supply and the equalizer. Identify the
negative lead by the ridges on the side of the cord
(see the illustration on page 2-8).
C Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned
wires are not as secure in the captive screw
connectors and could be pulled out.
W The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before continuing.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
Powering Via the Input Source
For shorter distances, the DVI 101 and the HDMI 101 can receive
power from the input device via the 5 VDC signal on pin 14
of the DVD 101 or pin 18 of the HDMI 101 (see the table on
page 2-8). This eliminates the external power supply. However,
for best unit performance, the external supply is recommended.
N If the source does not adequately supply the +5 V power,
an external power supply must be used.
To verify if the source is providing power, connect a short
DVI/HDMI cable from the input device to the input of
the DVI/HDMI. If the DVI 101 front panel LED lights
yellow, the source is supplying power.
Connecting for Long Cable Runs
To use the DVI 101 or HDMI 101 effectively in a long cable run
between the source and the display, position the DVI/HDMI
at the end of the cable closest to the display. See the diagram
below for an example.
