4.0 CONNECTING THE HARDWARE
Please study the images below and become familiar with the signal input,
output, and power input. See Section 5, “Operating the Unit,” for additional
information.

5.0 OPERATING THE UNIT
1. Turn OFF the DVI source and the DVI display device.
2. Connect a high quality DVI (long) cable between the output of the DVI
source and the “INPUT” port of the ACE™ unit.
3. Connect a high quality DVI (short) cable between the DVI input on the
display device and the “OUTPUT” port of the ACE™ unit.
4. Connect the External AC Power Adapter to the ACE™ unit. Take care to
insert the locking plug into the DC power connector on the ACE™ unit and
rotate a quarter turn clockwise so that it locks securely into position.
5. Plug the AC Power Adapter into an active AC power socket. The red
POWER LED should be illuminated.
6. Turn ON the DVI source and DVI display device. The green ACTIVE LED
should be illuminated, and there should be a stable image on the DVI
display. There should be no artifacts (streaks, sparkles, etc.) visible in the
displayed image.
7. On the side of the ACE™ unit there is a cable equalization switch that
can be set for AUTO (automatic) or MANUAL adjustment. The AUTO
position is preferred and works well with most cables. For DVI cables
longer than 30 meters (100 ft.), the MANUAL EQ position can give better
results. When the switch is set to the MANUAL EQ position, a 25x turn
potentiometer is activated, allowing very precise control of the amount of
cable equalization. For best results, take care to rotate this potentiometer
adjustment slowly. Note that at the end of its range you will feel a slight
clicking in the adjustment even though it continues to rotate.

6.0 TROUBLESHOOTING
If the DVI ACE™ unit does not appear to be working properly, please check the
following:
1. Verify that the External AC Power Adapter is plugged in and delivering power
to the DVI ACE™ unit. In this case the red POWER LED should be brightly lit.
If the red POWER LED is dim, ickering or off altogether, then check the AC
power source and/or replace the power adapter.
2. Verify that the cables connected to the Input and Output ports of the DVI
ACE™ unit are premium grade cables (such as DVIGear’s Super High
Resolution™ cables) and do not exceed the recommended cable lengths
specied in Section 2 of this User Guide.
3. Inspect the DVI connectors on both the cables and on the DVI ACE™ unit for
damage, bent pins, loose connections, etc.
4. Turn ON the DVI source and verify that the green ACTIVE LED is illuminated.
If it is not, double-check the source to ensure that it is outputting an active
DVI signal.
5. As a nal check, bypass the DVI ACE™ unit and connect the DVI source
directly to the DVI display device using a high quality DVI cable with a length
of 3 meters (10 ft.) or less. If the image is visible on the display, then follow
the procedure below in step 6.
6. Turn OFF all system components, as well as the DVI ACE™ unit. Restart
the DVI display, then the DVI ACE™ unit, and nally the DVI source device.
Recheck steps 1-4 above.
If the problem persists after trying the above suggestions, please contact your
dealer for additional assistance. If the dealer’s technical personnel are unable
