1. The Sequoia 4K60 can provide a total maximum current of 500mA for both of USB Type-A port marked
1 and 2; and another total maximum current of 500mA for both of USB Type-A port marked 3
and 4.
2. Please be advised when using wireless mouse/keyboard, signal interference may occur with other 2.4 GHz
devices in close proximity, leading to slow mouse movement or other issues. The Sequoia 4K60 has
multiple USB Type-A ports closely packed together, and with each USB Type-A port capable of supporting
one user connection, it would be best to use short USB extension cables to physically separate the
wireless USB receiver dongles, or use USB hubs for direct wired connections to mouse/keyboard/touch
screens to avoid any interference.
3. If you plan to use a USB hub to support more USB devices i.e. keyboard, mouse and touch screen, it is
strongly recommended to use a powered USB Hub to prevent any drops in performance. If a powered USB
HUB is not available, you may use an unpowered USB 2.0 Hub instead.
4. The following items can be commonly used for USB extension to avoid any interference:
A short USB extension cable can physically separate multiple
wireless USB receiver dongles concurrently connected to the
Sequoia 4K60, preventing any signal interference.
A USB hub for direct wired connections to mouse/keyboard
and/or touch screen is an option to completely prevent
interference.
For USB connections over longer distances (up to 150 feet),
USB extension over CATx cable is recommended.
Step 6. Connect one end of the USB A/B cables to the USB Type-B ports to touch screens and connect
other end to the USB hubs corresponding to the HDMI OUT ports.
Step 7. Connect the 12 V DC/5A power adapters to the Sequoia 4K60. Then press the power switch
button to ON position of Sequoia 4K60. The image will be displayed on touch screen around 60
seconds.
Step 8. Turn on power of the four computers and touch screens.
Step 9. Press Ctrl + T on your keyboard or tap anywhere (except the yellow and orange marks shown in
below figure) and hold the spot for seven (7) seconds to perform touch screen calibration (when
using the touch screen with the Sequoia 4K60 for the very first time or upon resetting your
Sequoia 4K60 to its default state).
