Before setting up the devices it will help you to understand how Single View
and Multi View setups affect the installation. The table below provides a
picture of the display connections in a Single View and Multi View setup. For
example, the first row shows that in a Single View - Mini DisplayPort setup,
you cannot connect a HDMI or Thunderbolt monitor and no Thunderbolt
Daisy-Chained devices can be connected.

Cable Connections
Installation of the US7220 is simply a matter of connecting the appropriate
cables. Refer to the installation diagram on the following page (the numbers in
the diagram correspond to the steps below), and do the following:
1. Use Thunderbolt cables (one is included with this package) to connect a
Thunderbolt-enabled Mac and/or PC to the Thunderbolt 2 ports on the
US7220. The power saving function will automatically shut down the
US7220 when the Mac or PC host is powered-off.
2. Connect a Thunderbolt (or Mini DisplayPort*) monitor to the Thunderbolt
2 Daisy-Chain port on the US7220. You can daisy-chain up to 4 additional
devices through the Thunderbolt 2 Daisy-Chain port.
3. Connect an HDMI monitor to the HDMI port on the US7220. The HDMI
monitor should automatically detect the additional display.*
4. Use mini digital optical (mini TOSLINK) or 3.5 mm analog audio cables
to connect the Line Out port to external speakers and the Line In port to a
microphone. The Line In and Line Out ports support optical signals for
higher quality playback.**
5. Use an eSATA cable to connect an external storage device to the eSATA
port.
6. Connect USB 3.0/2.0/1.1 peripherals to the USB 3.1 Gen 1 ports.
7. Connect a keyboard and mouse (or any other USB 2.0/1.1 peripheral) to
the USB 2.0 ports.
8. Connect a Cat 5e/6 LAN cable to the Ethernet port.
9. Connect a USB 3.0/2.0/1.1 peripheral device to the front USB port.
10.Plug the AC power adapter into the US7220's power jack, and plug the
other end into an AC power source.
Note: 1. If a Mini DisplayPort monitor is connected to the Thunderbolt 2
Daisy-Chain port, the monitor connected to the HDMI port will
not work. The US7220 supports either a Mini DisplayPort or
HDMI monitor but not both at the same time.
2. The audio Line In/Line Out ports only support optical or self-
powered sound devices, such as active speakers and mini sound
systems. To use passive headphones, you must use a digital
headphone amplifier.

adequate ventilation. To ensure reliable operation, and to protect against
overheating, these openings must never be blocked or covered.

The device should never be placed on a soft surface (bed, sofa, rug, etc.) as
this will block its ventilation openings. Likewise, the device should not be
placed in a built in enclosure unless adequate ventilation has been provided.
Never spill liquid of any kind on the device.
Unplug the device from the wall outlet before cleaning. Do not use liquid
or aerosol cleaners. Use a damp cloth for cleaning.
The device should be operated from the type of power source indicated on
the marking label. If you are not sure of the type of power available,
consult your dealer or local power company.
The device is designed for IT power distribution systems with 230V
phase-to-phase voltage.
To prevent damage to your installation it is important that all devices are
properly grounded.
The device is equipped with a 3-wire grounding type plug. This is a safety
feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not attempt to defeat the
purpose of the grounding-type plug. Always follow your local/national
wiring codes.
Do not allow anything to rest on the power cord or cables. Route the
power cord and cables so that they cannot be stepped on or tripped over.

If an extension cord is used with this device make sure that the total of the
ampere ratings of all products used on this cord does not exceed the
extension cord ampere rating. Make sure that the total of all products
plugged into the wall outlet does not exceed 15 amperes.
To help protect your system from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
un-interruptible power supply (UPS).
Position system cables and power cables carefully; Be sure that nothing
rests on any cables.
Never push objects of any kind into or through cabinet slots. They may
touch dangerous voltage points or short out parts resulting in a risk of fire
or electrical shock.
Do not attempt to service the device yourself. Refer all servicing to
qualified service personnel.
If the following conditions occur, unplug the device from the wall outlet
and bring it to qualified service personnel for repair.
The power cord or plug has become damaged or frayed.
Liquid has been spilled into the device.
The device has been exposed to rain or water.
The device has been dropped, or the cabinet has been damaged.
The device exhibits a distinct change in performance, indicating a need
for service.
The device does not operate normally when the operating instructions
are followed.
Only adjust those controls that are covered in the operating instructions.
Improper adjustment of other controls may result in damage that will
require extensive work by a qualified technician to repair.
Avoid circuit overloads. Before connecting equipment to a circuit, know
the power supply’s limit and never exceed it. Always review the electrical
specifications of a circuit to ensure that you are not creating a dangerous
condition or that one does not already exist. Circuit overloads can cause a
fire and destroy equipment.
