Introduction
Overview
The CS1964 4-Port USB3.0 4K DisplayPort Triple Display KVMP™ Switch
combines Triple Display KVM switch with DisplayPort video interface, 2-port
USB 3.1 Gen 1 hub and 2.1 channel audio support for rich bass surround sound.
DisplayPort technology provides 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 CS1964 allows users to access four DisplayPort computers from a single
USB keyboard, USB mouse and three HDMI monitors. In addition to the front
panel pushbuttons, Hotkeys, and the mouse port-switching functionality, the
CS1964 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 CS1964 will automatically switch ports to the next powered-
on computer.
With a built-in USB 3.1 Gen 1 hub, the CS1964 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
CS1964 delivers the latest innovations in desktop KVM switching technology.

Hardware Setup
Cable Connections
To set up your installation, refer to the installation diagram on the following
page (the numbers in the diagram on page 13 correspond to the steps below),
and do the following:
1. Plug your USB keyboard and USB mouse into the USB console ports
located on the unit’s rear panel.
2. Plug your monitor(s) into the HDMI console ports located on the unit’s
rear panel and power on the monitors.
3. Plug your microphone and speakers into the console microphone and
speaker jacks located on the unit’s front panel. Audio cables are required
on the CPU side for this connection to work.
4. Plug your microphone and speakers into the audio console ports located on
the unit’s rear panel. The microphone and speakers plugged into the front
panel have priority over those plugged into the rear panel.
5. Using the DisplayPort cable, plug the DisplayPort connector into an
available DisplayPort A socket on the KVM port section of the switch
(CPU 1, CPU 2, etc.), then plug the USB 3.0 cable, microphone/speaker
cables into their corresponding sockets. Using another DisplayPort cable,
plug the DisplayPort cable connector into the DisplayPort socket B in the
same KVM port section of the switch. Repeat for DisplayPort socket C.
6. At the other end of the cables from step 5, plug the microphone/speaker
cables into their respective ports on the computer.
1. Important safety information regarding the placement of this
device is provided on page 39. Please review it before
proceeding.
2. Make sure that power to all the devices you will be installing has
been turned off. You must unplug the power cords of any
computers that have the Keyboard Power On function.

7. At the other end of the DisplayPort cable and USB 3.0 cable from step 5,
plug the DisplayPort cable into its respective port on the computer. Repeat
steps 5, 6, and 7 for each triple-screen PC system you are installing.
8. (Optional) Plug your USB peripherals into the front or rear USB
peripheral ports.
9. Plug the power adapter that came with your switch into an AC power
source, then plug power adapter cable into the switch’s Power Jack.
10. Power on the computers.
Note:
By default, the switch links to the first computer that is powered on.
The total cable length from the PC to monitor (including KVM) cannot
exceed 3.3 meters.
Choosing high quality cables helps to ensure that 4K UHD (3840x2160
@ 60 Hz) or 4K DCI (4096x2160 @ 60 Hz) resolutions can be
reached.
It is highly recommended that the CS1964 is kept powered on at all
times.
