Introduction
Overview
The CS1922M / CS1924M 2/4-Port USB 3.0 4K DisplayPort MST KVMP™
Switch takes a giant leap forward in KVM switch functionality by combining
a KVM switch with a DisplayPort video interface, 2-port USB 3.1 Gen 1 hub,
MST hub and 2.1 channel audio for rich bass in surround sound. DisplayPort
technology provides a 4K UHD @ 60 Hz and 4K DCI @ 60 Hz resolution that
displays the most vivid high-definition images available while pumping out
premium sound for music, movies, and games.
As a KVM switch with built-in MST hub, the CS1922M / CS1924M allows
users to access two or four DisplayPort computers from a single USB
keyboard, USB mouse and DisplayPort or HDMI monitor console. In addition
to the front panel pushbuttons, hotkeys, and RS-232, the CS1922M / CS1924M
offers the latest mouse port-switching functionality which allows a double-
click of the scroll-wheel to change ports. A Power On Detection feature also
ensures that if one computer is powered off, the CS1922M / CS1924M will
automatically switch ports to the next powered-on computer.
The 2-port USB 3.1 Gen 1 hub provides SuperSpeed 5 Gbps data transfer
speeds to all connected 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.
The CS1922M / CS1924M's built-in MST hub can receive DisplayPort™ 1.2
signals from the source device and split it to independently route the video
signal to multiple monitors.
Featuring an unbeatable combination of ultra high 4K resolutions, a next
generation USB 3.1 Gen 1 hub and enhanced, user-friendly operations, the
CS1922M / CS1924M provides the latest innovations in desktop KVM
technology.

3. MST (Multi-Stream Transport) requires either monitors capable of
DisplayPort 1.2 daisy-chaining, or use of a powered DisplayPort
MST Hub. A DisplayPort v1.1a display can be the last display in a
DisplayPort v1.2 chain. The PC source must be DisplayPort 1.2
compliant.
4. DisplayPort Dual-Mode (DP++) does not require an active adapter
for most single display setups. Active DisplayPort adapters are
recommended if you are unsure of the video source's DP++
compatibility.
5. PC keyboard combinations emulate Mac keyboards. Mac keyboards
only work with their own operating system.

Troubleshooting
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 The Firmware Upgrade Utility, Chapter 6, for upgrade
details.
