1. Getting Started
The Avitech Sequoia UHD is a highly innovative device that comes with its own embedded operating
system and graphic engines. The Sequoia UHD 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
UHD being able to connect up to four-plus-one computers and instantly switch inputs among them,
users can monitor and remotely control any four computers at the same time on a single display plus a
fifth computer on a full-screen display with just one set of keyboard and mouse. The Sequoia UHD also
supports a variety of video formats from HDMI to DVI-D.
The Sequoia UHD features an on-screen pop-up selection plus mouse right-click menu that allows
handy operation and control of the device. By clicking the relevant pop-up selections’ icon or pressing
the hot-keys through the keyboard, 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 allows users to
freely set up or configure numerous features for different applications; including audio source routing.
In addition to its interface and features, the Sequoia UHD can enter Remote mode to transfer keyboard
and mouse 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 UHD allows users
to freely switch control between the computers and the host Sequoia in an intuitive manner.

Step 1. Connect the first computer’s display output to the HDMI input port (HDMI IN 1) of the Sequoia
UHD. Repeat the step for all source computers (HDMI IN 2~ 4).
Be sure to connect the first computer to HDMI IN 1, the second computer to HDMI IN 2, and so forth.

8
Step 2. To simultaneously view four concurrent HDMI 1.4 computer sources on a single monitor (up to
4K30), connect a HDMI monitor to the HDMI (HDMI OUT) port of the Sequoia UHD.
Step 3. Connect a USB A/B cable to the first computer’s USB type A port, and connect the other end to
the USB type B port (USB IN 1) of the Sequoia UHD. Repeat this step for all source computers
(USB IN 2~ 4).
1. Be sure to connect the first computer to USB IN 1, the second computer to USB IN 2, and so forth.
2. (For Windows 2000 users) Upon connecting your Sequoia UHD to a computer through the USB interface
for the first time, perform the Windows' on-screen steps to initialize the USB connection.
Step 4. Connect a set of keyboard and mouse to the K/M USB type A ports of the Sequoia UHD that will
be used to operate the Sequoia UHD and the four source computers.
Non-standard keyboards (i.e. keyboards with a USB hub, keyboards that need driver installation and
programmable keyboards, etc.) are not supported.
Step 5. Connect a USB A/B cable to the fifth computer’s USB type A port, and connect the other end to
the USB type B port (PC) of the Sequoia UHD. The Sequoia UHD supports a fifth set of KM
(keyboard/mouse) switching on a second monitor next to the multiview display in dual monitor
operation setup.
Step 6. Make sure to power-on the four concurrent computers as well as the fifth computer.
Step 7. Connect one end of the AC power cord to the 100~240V power in jack on the Sequoia UHD.
Step 8. Connect the other end of the AC power cord to power outlet. After the initial 30 seconds or more
booting time has elapsed, the four windows (each containing image from one of the connected
computers) will appear, along with the Host cursor that can be controlled directly through the
mouse connected to your Sequoia UHD's K/M USB type A ports.
Step 9. (Optional –to achieve power redundancy)
Connect one end of the optional 12 V DC power adapter to the DC 12V/9A power in jack on the
Sequoia UHD.
Step 10. Connect the other end of the optional 12 V DC power adapter to power outlet. Power (AC or
DC) can then be unplugged without affecting the power supply to the Sequoia UHD.
Step 11. The pop-up selections will appear upon moving the Host cursor to each of the
four window’s top-right position:
Click the Login icon on a selected window to enter the Sequoia UHD's Remote mode.
Remote mode allows direct connection to the selected computer through USB interface.
Your Sequoia UHD’s (Host) keyboard and mouse will now control the selected computer; the
Host cursor will disappear when your Sequoia UHD 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 UHD’s (Host) keyboard and mouse
control to that computer.
Press the Pause/Break hot-key on the keyboard or double-click the mouse scroll button
connected to your Sequoia UHD's rear panel to return keyboard and mouse control to the
Sequoia UHD. The Host cursor will reappear.
Move the Host cursor across two displays to access computers confined to each Sequoia
UHD.
The pop-up selections are not available on the fifth computer’s monitor.

3. Basic Operations
The Sequoia UHD 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
On the multiview display:
When Sequoia UHD is in Host mode, the Host cursor appears on the display upon connecting a mouse
device to the Sequoia UHD’s K/M USB type A ports. The cursor will be controlled by this locally
connected mouse. 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 auto-hide
menu are features of this mode to enhance ease of control and operation and are discussed in detail in
Appendix A and C.
Upon re-connecting a keyboard or mouse, the Host cursor may disappear. Move the mouse to allow it to
re-appear.
On the second display:
Control the computer as you regularly would through the corresponding window on the display without
the need for the pop-up selections, right-click menu or auto-hide menu.
In summary:
As long as you are in Host mode, upon moving the Host cursor to the left or right edge of the multiview
display or second monitor will cause the Host cursor to jump to the second monitor or multiview display
and vice versa.
Remote Mode
On the multiview display with “Surfer” feature:
When Sequoia UHD enters Remote mode, the Host cursor disappears, and the “Surfer” feature is
enabled. Notice that the window’s border will turn “yellow”, this signifies that your Sequoia UHD is now in
Remote mode with “Surfer” function. Entering Remote mode, your Sequoia UHD transfer keyboard and
mouse control to the selected computer system. You can then control the computer as you regularly
would within the window on the display. Your Sequoia UHD can only enter Remote mode to take control
of a computer when the correct USB type B port (USB IN 1~ 4) on your Sequoia UHD'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.
On the second display:
Control the computer as you regularly would through the corresponding window on the display without
the need for the pop-up selections, right-click menu or auto-hide menu.
In summary:
Whether you are in the multiview display’s Remote mode with “Surfer” function or Host mode, upon
moving the cursor away from the multiview monitor to the second monitor with full screen display, the
system basically switches the mouse to Remote mode automatically.
Tips on Navigating the Sequoia UHD:
A maximum of four plus one computers can be connected to a single Sequoia UHD. The Sequoia
UHD puts the images of four computers onto four windows and simultaneously displays them on
the monitor. Instant switching of inputs through the user interface is supported; thus, any of the
four plus one computers can be monitored and controlled on the dual displays.

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 (“Surfer” feature is automatically active), your Sequoia UHD
automatically transfers its keyboard and mouse control to the selected computer. Use the
keyboard and mouse to control that computer as you regularly would.
To switch back to Host mode, use the keyboard Pause/Break hot-key, or double-click the mouse
scroll button. The Sequoia UHD will return to Host mode and the Host cursor will reappear.
