Introduction
Overview
The CS1942DP / CS1944DP 2/4-Port USB 3 0 4K DisplayPort Dual Display
KVMP™ Switch takes a giant leap forward in KVM switch functionality by
combining a Dual Display KVM switch with a DisplayPort video interface,
2-port USB 3 1 Gen 1 hub and 2 1 channel audio support for rich bass in
surround sound DisplayPort technology provides a 4K UHD @ 60 Hz and 4K
DCI @ 60Hz resolution that displays the most vivid high-definition images
available while pumping out premium sound for music, movies, and games
The CS1942DP / CS1944DP allows users to access two or four DisplayPort
computers from a single USB keyboard, USB mouse and two DisplayPort
monitors In addition to the front panel pushbuttons, Hotkeys, and the mouse
port-switching functionality, the CS1942DP / CS1944DP offers serial
commands to help switch ports and configure device settings A Power On
Detection feature also ensures that if one computer is powered off, the
CS1942DP / CS1944DP will automatically switch ports to the next powered-
on computer
With a built-in USB 3 1 Gen 1 hub, the CS1942DP / CS1944DP 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
Featuring an unbeatable combination of ultra high 4K resolutions, a next
generation USB 3 1 Gen 1 hub and enhanced, user-friendly operations, the
CS1942DP / CS1944DP delivers the latest innovations in desktop KVM
switching technology

refer to the CS1942DP_CS1944DP RS-232 Commands
document
3 For DisplayPort 1 4 compliant display device, make sure to
configure the device setting to be compatible with DisplayPort
1 2 to avoid compatibility issue
4 HD audio through DisplayPort cannot be switched independently
5 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
6 DisplayPort Dual-Mode technology (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

Cables
To guarantee video quality, we recommend using only ATEN DisplayPort
KVM cables which are certified by the VESA Compliance Program Four
(CS1942DP) or eight (CS1944DP) cables are provided with this package
Note: 1 The quality of the display is affected by the quality of the cables
We recommend the total length from the source to the monitor to
not exceed 3 meters (1 5 meters between the PC and the KVM
switch 1 5 meters between the KVM switch and the monitor) If
you need additional cables, please contact your dealer to purchase
ATEN approved cables
2 If you are using DisplayPort cables that are only DP 1 1
compliant, make sure the DisplayPort EQ setting of the monitor
is set to auto or DP 1 1
