4-port air-traffic-control DisplayPort multi-view KVM switches
supporting EDID Aux emulation, with seamless switching, redundant power, specialized ATC resolution, 1 or 2 screens, USB 2.0 peripheral sharing, audio and RS-232 support
• Specialized air-traffic-control (ATC) resolutions, including 2048x2048 @ 60Hz, with front-panel resolution-toggle push-button
• RS-232 serial communication support for each computer-port, for full RS-232 switching supporting legacy printers
• Power failover support – two AC IEC inlets for power redundancy to ensure constant availability
• Independent (asynchronous) switching of KVM, USB peripherals and audio ports – users can listen to audio from one computer while working on a different computer, or scan a document and save it on another computer
• Integrated multiviewer for simultaneous monitoring of multiple systems on one screen with flexible viewing modes (Full-Screen, Dual-Mode, Quad-Mode, Tri-View Mode and Picture-in-Picture Mode)
• True seamless switching: No video blanking or re-sync, for real-time decision making
• Web-based and RS-232 configuration and control
ATC DisplayPort high-performance multi-view KVM switches are purpose-built for 24/7 air-traffic-control (ATC) operations, capable of managing four DisplayPort computers through one or two DisplayPort monitors, one USB keyboard/mouse, and a set of speakers, while sharing USB peripherals like printers, memory devices, scanners, etc.
Designed to meet the demanding requirements of modern air-traffic-control (ATC) environments, ATC DisplayPort high-performance multi-view KVM switches enable controllers to securely manage multiple critical systems – including radar, flight data, surveillance, and weather platforms – from a single, unified workstation.
ATC DisplayPort high-performance multi-view KVM switches support specialized ATC resolutions such as 2048x2048 @ 60Hz, ensuring precise visualization where accuracy is mission-critical.
ATC DisplayPort high-performance multi-view KVM switches are engineered for reliability, performance, and operational continuity – ensuring controllers have uninterrupted access to the systems they depend on.
ATC DisplayPort high-performance multi-view KVM switches support resolutions of up to 4K 3840x2160 @ 60Hz with zero pixel loss from TMDS signal correction, delivering crystal-clear visuals for your demanding tasks.
Not just limited to video, keyboard and mouse emulation, ATC DisplayPort high-performance multi-view KVM switches extend their connectivity to additional USB 2.0 devices, such as printers, scanners, and web cameras, providing a comprehensive solution for diverse needs.
The main function of these KVM switches is to centralize the access of four computer into a single, comprehensive KVM console.
Their USB 2.0 functionality support allows users at the console to access USB devices that would otherwise be unavailable. For example, it allows the use of a flash memory drive or camera without having to plug it directly into the remote computer.
By centralizing IT hardware outside the control room, the system significantly reduces heat, noise, and clutter, while delivering real-time, zero-disruption access to all connected systems – including those requiring RS-232 communication.
Featuring flash upgradeable firmware, front panel keys for manual port selection, and hot-key commands for swift navigation, these KVM switches ensure user-friendly control.
Screen Modes

EDID Aux Emulation
With EDID Aux (DisplayPort Auxiliary channel) video emulation, your window and monitor configurations remain intact when switching between computers, ensuring a smooth and uninterrupted workflow.
Unlike traditional DisplayPort KVM switches, SM-EDPN-ATC-4S is designed to overcome the inherent DisplayPort loss of emulated picture when switching from one connected computer to another (leading to a disorganized desktop video upon switching). SM-EDPN-ATC-4S's built-in EDID Aux emulation offers full EDID video emulation that ensures visual workspaces and screen resolutions are remembered every time you switch between computers.
ATC DisplayPort high-performance multi-view KVM switches' built-in EDID Aux emulation offers:
• Consistent screen resolutions: With EDID (Aux) Emulation, your screen resolutions stay static, providing a stable visual experience when switching between connected computers
• Persistent icon and window positions: Switch between connected computers without the chaos - icons and window positions remain undisturbed, ensuring a smooth transition between tasks
Flexible Control
Any external device or program supporting RS-232 can control SM-EDPN-ATC-4S. ATC DisplayPort high-performance multi-view KVM switches use a very simple protocol, enabling easy integration with the RS-232 control devices.
A front-panel push-button along with keyboard hot-keys also allow the user to switch and control all the different functions of the KVM switch.
The USB emulation technology utilized by ATC DisplayPort high-performance multi-view KVM switches enable immediate hot key source switching through the connected USB keyboard and mouse. Additional USB peripherals can be attached, like a USB printer. RS-232 control and front panel switching are also supported.
Flexible Sharing
ATC DisplayPort high-performance multi-view KVM switches support independent simultaneous device selection. It enables the use of a USB keyboard and mouse on one computer while other USB peripherals such as speakers, scanners and printers are connected to the other computer source. ATC DisplayPort high-performance multi-view KVM switches maintain the ability to switch all connected devices to any one of the computer sources as with any other KVM switch in the market.
SM-EDPN-ATC-4D: Supports 4x dual-video computers and two screens
SM-EDPN-ATC-4S: Supports 4x single-video computers and one screen
