5.0 OPERATING THE UNIT

5.1 Connect the Unit as follows:

1. Turn off power to source device (such as PC) and to all display devices
(such as monitors).

2. Connect the output of the source device to the amplifier’s input with the
HD-15 cable provided.

3. Connect the input of the display devices to the output connectors of the
amplifier with high quality HD-15 cables, up to 300 feet in length.

4. Plug the DC connector from the 5VDC power adapter provided into the
amplifier. Twist the DC connector after inserting it to lock it in place.

5. Plug the power adapter into an AC outlet.

6. Turn on power to the source and display devices.

Note: If you connect a DDC (Plug-and-Play) monitor to output 1 of the amplifier,
all the other display devices must be able to support the same resolutions as the
DDC monitor.

5.2 CASCADING

To display the same image on more monitors than available amplifier outputs
permit, you may cascade additional amplifiers. Connect the input of the additional
amplifier with an HD-15 cable to an output of the original amplifier.

Caution - Signal degradation may occur if too many amplifiers are cascaded.

6.0 TROUBLESHOOTING

Problems with the DA1200P amplifier are rare. Most of the time, the problem is
caused by the use of an incorrect cable for the signal type, to long a cable run,
bad connectors on the cable and occasionally damaged cables. Bad grounds or
use of different AC power sources for the DA1200P amplifier, source and/or
display device(s) may also cause problems due to ground loops.

After trying the above suggestions should the problem still persist, contact your
dealer for additional suggestions before contacting Avocent. Should the dealer’s
technical personnel be unable to assist you, contact Avocent via our support
website: http://support.avocent.com. Create a technical support request on
the site and our support team will respond within a short period of time.
