1. Getting Started
The Avitech Sequoia Dual is a highly innovative device that comes with its own embedded operating
system and graphic engines. The Sequoia Dual integrates functions of a KVM (keyboard video mouse)
switch and a robust multi-viewer into one enclosure, providing a simple multi-viewing solution for any
user who works in an environment with multiple computer and video systems. With a single Sequoia
Dual being able to connect up to four computers and instantly switch inputs among them, users can
monitor and remotely control any two computers at the same time on a single display with just one set of
keyboard and mouse. The Sequoia Dual also supports a variety of video formats from HDMI, DVI-I to
VGA and YPbPr. Additionally, its scalability through cascading with other Sequoia devices makes the
Sequoia Dual an ideal solution to both individual users and corporate applications.
The Sequoia Dual features an on-screen user interface which allows handy operation and control of the
device. By giving relevant mouse commands through the interface, users can easily convert monitoring
styles to various layouts, and adjust windows to any size and position on the display. The mouse
right-click menu available through the on-screen interface allows users to freely set up or configure
numerous features for different applications. In addition, the top menu allows users to lock their windows
in size and position, and load previously saved layouts.
In addition to its freely adjustable interface and features, the Sequoia Dual can enter Remote mode to
transfer mouse and keyboard control from the Sequoia to the connected computer systems. Users can
then remotely control any of the connected computers with the set of keyboard and mouse on the
Sequoia. The “Surfer” feature, along with other user-friendly commands supported by the Sequoia Dual
allows users to freely switch control between the computers and the host Sequoia in an intuitive manner.
Furthermore, for more hands-on user experiences, the Sequoia Dual can be used with a touch-screen
display. The touch-screen controls are receptive and intuitive, allowing source switching, window
resizing and repositioning, and control of remote computers with just a tap of your finger.
This chapter will continue to introduce more features and specifications as well as external components
of your Sequoia Dual.

1.2 Product Features
The Sequoia Dual is HDCP-compliant and capable of handling HDMI®, DVI-I, VGA and YPbPr inputs.
Featuring two DVI-I and two HDMI input ports, and one HDMI output port, a single Sequoia Dual can
connect up to four computers, four videos, or any combination of four inputs. It can simultaneously
display any two of the four inputs on a single display, and allows instant switching of inputs through its
on-screen user interface.
The Sequoia Dual features in automatic sensing of input signals, automatic detection and selection of
optimum display resolution; it also supports hot-swapping which allows addition and removal of any
input/output signals without powering down the device.
For audio monitoring, the Sequoia Dual features a 1/8 inch headphone jack. It also accepts embedded
HDMI® audio (8ch-stereo) and analog audio (2ch-stereo).
For operation, the Sequoia Dual provides a friendly on-screen user interface that can be controlled by a
set of keyboard and mouse, allowing free switching of operating modes and adjustments for numerous
behavior that suits different applications. In addition, with Avitech Hook Utility (patent pending), a
computer with its own keyboard and mouse can also be used to control the Sequoia Dual through the
USB type B port on its front panel .The Sequoia Dual also features in multi-touch support and is
compatible with touch-screen displays, offering more flexibility for operation and control.
In addition to monitoring, the Sequoia Dual can remotely control the connected computers through the
USB keyboard and mouse connected to its front panel. Utilizing the “Surfer” feature – which allows users
to transfer keyboard and mouse control from one computer to another by simply moving the mouse
cursor to the window border of the targeted computer, the Sequoia Dual is able to seamlessly switch
between and control any of the four computers connected to it with just one set of keyboard and mouse.
Integrated file and folder transfer across computers provides convenient file management. By selecting
an origin and a destination through the on-screen user interface, the Sequoia Dual allows simple
copy/cut and paste of files/folders across connected computers using its embedded file managing utility,
Go! Bridge.
The Sequoia Dual also supports streaming its display through Ethernet connection, allowing computers
at far ends to perform remote monitoring and control of the Sequoia. Its video over IP operates on

2. System Configuration
This chapter discusses the process of setting up your Sequoia Dual.
2.1 Getting the Sequoia Dual Ready
To control your Sequoia Dual directly, connect a keyboard and mouse to the USB type A ports on
its front panel. Alternatively, to control your Sequoia Dual on a computer, use a laptop (or desktop)
computer with its own keyboard and mouse and connect to your Sequoia Dual’s USB type B port on
its front panel (use a USB A/B cable), and then run the Hook Utility on this controlling computer to
simulate mouse and keyboard operation.
When using a touch-screen display, connect the display to one of the USB type A port with a USB
cable to simulate mouse-click action. The Sequoia Dual can then be controlled by tapping your finger on
the display.
1. The Hook Utility currently supports the Sequoia solo series (non-cascaded) and the Pacific X-HDU. With
Hook Utility, use the connected computer to simulate keyboard and mouse function for remote control
processing (KVM feature).
2. Refer to the Hook Utility user manual for more details.
2.1.1 Basic Setup When Connecting a Regular Display or Touch-screen Display
The following figures show a typical setup with a single Sequoia Dual connected to four computers and
a regular/touch-screen display.

2.1.2 Basic Setup When Cascading the Sequoia Dual
Cascade is the technique of “daisy-chaining” multiple Sequoia Dual (up to five) through a USB A/B
cable(s). It can be used when larger applications that involve having multiple computer systems
controlled by a master device. It should be noted that only the keyboard and mouse are cascaded; in
other words, when cascading, one set of keyboard and mouse can be used to control five Sequoia Dual
(or other Sequoia series) by “surfing” the Host cursor across five displays and switch over control to any
of the connected computers. Other functions (e.g., audio, video, and USB hub) are still confined to the
associated Sequoia Dual to which they are connected (see Figure 2-3).
The following figure shows three Sequoia Dual cascaded together, with each Sequoia Dual connected
to four computers.
Cascading is available on the Sequoia Dual, 4H, and 2H2U. A combination of any of these Sequoia devices
can be cascaded to meet custom applications.

Step 1. Perform step 1 – 4 for your first Sequoia Dual as outlined in the previous section (2.1.1)
“Basic Setup When Connecting to a Regular or Touch-screen Display.”
Step 2. Repeat the above-mentioned steps for your second and third Sequoia Dual to be cascaded.
Step 3. Connect a mouse and keyboard to the USB type A ports located on your first Sequoia
Dual’s front panel.
Step 4. Connect your first Sequoia Dual’s USB type B port to one of the second Sequoia’s USB
type A port using a standard USB A/B cable. Repeat this procedure to connect the second
Sequoia Dual to the third one.
Step 5. Move your Host cursor across all three displays to allow the system to complete the USB device
initialization.
If the Host cursor is unable to move over all three displays, perform step 5 and 6 again.
Step 6. The pop-up selections will appear upon moving the Host
cursor to a window’s top-right position:
Click the icon on a selected window to enter the Sequoia Dual's Remote mode.
Remote mode allows direct connection to the selected computer through USB interface.
Your Sequoia Dual’s (Host) keyboard and mouse will now control the selected computer; the
Host cursor will disappear when your Sequoia Dual is in Remote mode.
The “Surfer” feature (default setting is ON) is enabled. Moving your cursor out of your
current window's border toward the other window, or to the edges that are shared with the
other window will automatically switch over your Sequoia Dual’s (Host) keyboard and mouse
control to that computer.
Press the Pause/Break hot-key on the keyboard connected to your Sequoia Dual's front
panel to return keyboard and mouse control to the Sequoia Dual. The Host cursor will
reappear. Right-click anywhere and select Options
Surfer to toggle off this feature if
desired.
Move the Host cursor across three displays to access computers confined to each Sequoia
Dual.

3. Basic Operations
The Sequoia Dual always operates in one of its two operating modes: Host and Remote mode. Users
are allowed to freely switch between these two modes anytime during the operation for different uses.
This chapter discusses these operating modes, their functions, and hot-keys in details.
Host Mode
When your Sequoia Dual is in Host mode, the Host cursor appears on the display upon connecting a
mouse device to the front panel of your Sequoia Dual. The cursor will be controlled by this locally
connected mouse (In the case of a cascaded setup the cursor will be controlled by the mouse device
connected to the Master Sequoia Dual; in the case of using a touch-screen display, the Host cursor can
be controlled by a tap of a finger). Host mode provides a monitoring solution for the incoming
computer/video signals. Users can use the Host cursor to select and adjust window size, position, and
display layout directly through the on-screen interface. Other features such as the mouse right-click
menu and the top menu are features of this mode to enhance ease of control and operation and are
discussed in details in Appendix A and D.
Upon re-connecting a keyboard or mouse, the Host cursor may disappear.
Press the Pause/Break key to solve this problem.
Remote Mode
When your Sequoia Dual enters Remote mode, the Host cursor disappears, and your Sequoia Dual
transfers the connected mouse and keyboard control to a selected computer system. You can then
control this computer as you regularly would through the corresponding window on the display. Your
Sequoia Dual can only enter Remote mode to take control of a computer when the correct USB type B
port on your Sequoia Dual's rear panel is properly connected to the USB type A port of that computer
(using a standard USB A/B cable). In addition, only windows corresponding to computer systems (as
opposed to pure video systems) can be accessed through Remote mode.
Tips on Navigating the Sequoia Dual:
A maximum of four computers can be connected to a single Sequoia Dual. The Sequoia Dual
puts the images of two selected computers onto two windows and simultaneously displays them
on the monitor. Instant switching of inputs through the user interface is supported; thus, any two
of the four computers can be monitored and controlled on the display.
When Host mode is active, use the mouse connected to your Sequoia Dual to resize and
reposition windows on the display.
To switch from Host mode to Remote mode, move the Host cursor to the top-right corner of the
targeted window and then click the Login icon (or double-click your mouse's left button any
area within that window).
When entering Remote mode, your Sequoia Dual automatically transfers its mouse and
keyboard control to the selected computer. Use the mouse and keyboard to control that
computer as you regularly would.
To switch back to Host mode, use the keyboard hot-key Pause/Break, or double-click the
mouse scroll button. The Sequoia Dual will return to Host mode and the Host cursor will
reappear.
