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 double­click 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.

Chapter 1. Introduction
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.

CS1922M / CS1924M User Manual

Requirements

Console

A DisplayPort or HDMI monitor capable of the highest possible resolution
A USB mouse
A USB keyboard
Microphone and speakers

Computers

The following equipment must be available on each computer:
DisplayPort port
USB Type A port
Audio ports

Cables

To guarantee video quality we recommend using only ATEN DisplayPort KVM cables which are certified by the VESA Compliance Program. Two (CS1922M) or four (CS1924M) cables are provided with this package.
Note: 1. The video quality displayed is affected by the quality and length of the
cables you use. We recommend the total length from the source to the monitor not exceed 3 meters. If you need additional cable sets, please contact your dealer to purchase ATEN approved cables.
2. If you use DisplayPort cables that are DP 1.1 compliant, make sure the DisplayPort EQ setting on the monitor is set to auto or DP 1.1.
