The transmitter connects externally to the video, audio and USB ports of the target computer and is
attached directly to the target computer. It captures, compresses and encrypts the computer’s media
stream and transmits it to the user station over a standard TCP/IP network. The user station enables
the desktop user’s keyboard, video, mouse and audio devices to connect to the HMX system.
Safety precautions
To avoid potentially fatal shock hazard and possible damage to equipment, please observe the
following precautions:
• Do not use a 2-wire power cord in any product configuration.
• Test AC outlets at the target computer and monitor for proper polarity and grounding.
• Use only with grounded outlets.
NOTE: The AC inlet is the main power disconnect.
CAUTION: Failure to observe the precautions in this section may result in personal injury or damage to
equipment.
Observe the following general safety precautions when setting up and using Avocent equipment.
• Follow all cautions and instructions marked on the equipment.
• Follow all cautions and instructions in the installation documentation or on any cautionary
cards shipped with the product.
• Do not push objects through the openings in the equipment. Dangerous voltages may be
present. Objects with conductive properties can cause fire, electric shock or damage to the
equipment.
• Do not make mechanical or electrical modifications to the equipment.
• Do not block or cover openings on the equipment.
• Choose a location that avoids excessive heat, direct sunlight, dust or chemical exposure, all of
which can cause the product to fail. For example, do not place an Avocent product near a
radiator or heat register, which can cause overheating.
• Ensure that the voltage and frequency of the power source match the voltage and frequency on
the label on the equipment.
• AC power supplies have grounding-type three-wire power cords. Make sure the power cords
are plugged into single
-phase power systems that have a neutral ground.
