Introduction
Overview
The CS1822 / CS1824 2/4-Port USB3.0 4K HDMI KVMP™ Switch combines
KVM switch with HDMI video interface and 2-port USB 3.1 Gen 1 hub. The
HDMI interface provides 4K UHD @ 60 Hz and 4K DCI @ 60Hz resolution
that displays the most vivid high-definition images available while producing
premium sound for music, movies, and games.
The CS1822 / CS1824 respectively allows users to access two or four HDMI
computers from a single USB keyboard, USB mouse and HDMI monitor. In
addition to the front panel pushbuttons, Hotkeys, and the mouse port-switching
functionality, the CS1822 / CS1824 offers serial commands to help switch
ports and configure device settings. ATEN default EDID Mode is available for
smooth power-up, high-quality display and eliminates monitor compatibility
issue. A Power On Detection feature also ensures that if one computer is
powered off, the CS1822 / CS1824 will automatically switch ports to the next
powered-on computer.
With a built-in USB 3.1 Gen 1 hub, the CS1822 / CS1824 provides SuperSpeed
5 Gbps transfer rates to all connected USB peripherals. The unit’s independent
(asynchronous) switching feature, allows the KVM focus to be on one
computer while the USB peripheral focus is on another computer. This
eliminates the need to purchase a separate USB hub or stand-alone peripheral
sharer – such as a print server, modem splitter, etc. For further customization,
the CS1822 / CS1824 provides audio mixing modes where you can combine
up to two audio sources as your audio output.
Featuring an unbeatable combination of ultra high 4K resolutions, a next
generation USB 3.1 Gen 1 hub and enhanced, user-friendly operations, the
CS1822 / CS1824 delivers the latest innovations in desktop KVM switching
technology.

Troubleshooting
Overview
Operation problems can be due to a variety of causes. The first step in solving
them is to make sure that all cables are securely attached and seated completely
in their sockets.
In addition, updating the product’s firmware may solve problems that have
been discovered and resolved since the prior version was released. If your
product is not running the latest firmware version, we strongly recommend that
you upgrade. See Chapter 6, The Firmware Upgrade Utility, for upgrade
details.
