ATEN USB Single Link Dvi-i Dual Display - KE6940AIT

ATEN KE6940AIT USB Dual-Display DVI-I KVM over IP Extender

The ATEN KE6940AIT is a USB KVM-over-IP extender designed for dual-display DVI-I environments where operators need full 1920x1200 resolution at 60Hz across a network link. It targets control rooms, broadcast suites, and secure operations centers where the source computer must remain physically separated from the operator workstation — with keyboard, mouse, and dual video signals transported over IP.

Key Features

• 1920x1200 @ 60Hz Video Resolution: Full WUXGA output on both displays — enough pixel density for side-by-side application windows or dual-monitor control consoles without downsampling artifacts. If your operators work with map overlays, video walls, or multi-pane VMS layouts, this resolution keeps content sharp at native panel density.
• Sub-5ms Latency to KE Unit: The KE6940AIT delivers less than 5ms latency to the KE receiver — fast enough that keyboard and mouse input feel local. The 50ms path back to the source PC is within the threshold most operators won't perceive during standard monitoring tasks.
• Three-Mode Slide Switch: A single physical slide switch on the unit toggles between Auto, RS-232 Config/Access Control, and Local modes. This matters during commissioning: you can configure or access-control the extender without touching software, reducing setup friction in locked-down environments.
• USB Keyboard and Mouse Support: Standard USB HID connectivity means no proprietary drivers or special peripherals — existing USB keyboards and mice drop straight in. Simplifies hot-desk and operator-rotation setups where peripheral standardization matters.
• 0–95% RH Non-Condensing Humidity Tolerance: Suitable for the humidity range found in typical data centers and control rooms. Not rated for outdoor or high-condensation environments — confirm environmental conditions before rack placement.
• Active Firmware (v1.8.173, April 2026): The current firmware release dates to April 15, 2026, indicating the product line is actively maintained. Firmware updates are delivered via a shared package covering both KE6900AIT and KE6940AIT units.

Integration and Compatibility

The KE6940AIT uses a rack-mount form factor — confirm your rack depth and adjacent unit clearance before ordering. The RS-232 Config/Access Control mode on the slide switch supports integration with building access control or serial-based management systems, useful in secured facilities where IP-based management must be supplemented by physical access controls. The shared firmware package with the KE6900AIT (single-display variant) suggests common management infrastructure across both models if you're deploying a mixed extender environment.

Frequently Asked Questions

Q: What video resolution does the KE6940AIT support?

A: The KE6940AIT supports up to 1920x1200 at 60Hz on its dual DVI-I display outputs.

Q: What is the latency of the KE6940AIT?

A: Latency to the KE unit is less than 5ms; latency back to the source PC is less than 50ms.

Q: How do you switch modes on the KE6940AIT?

A: A physical slide switch on the unit selects between Auto, RS-232 Config/Access Control, and Local modes — no software required for mode changes.

Q: What is the latest firmware version for the KE6940AIT?

A: As of April 15, 2026, the current firmware is v1.8.173, available in a shared package covering both the KE6900AIT and KE6940AIT.

Q: What keyboard and mouse interfaces does the KE6940AIT support?

A: The KE6940AIT uses standard USB for keyboard and mouse — no proprietary peripherals required.

James Everett

The KE6940AIT's sub-5ms latency to the KE receiver is the number that matters most in operator-driven deployments — at that threshold, the keyboard and mouse feel local even though the source computer may be a rack away in a locked IDF or across a secured LAN segment. That's the core value proposition of this extender for control room and NOC environments.

Technical Highlights:

• Dual DVI-I at 1920x1200: WUXGA on two independent displays covers side-by-side VMS, SCADA, or map-plus-video layouts without resolution compromise — important when operators need pixel-dense content on both screens simultaneously.
• Three-Position Mode Slide Switch: Physical mode selection (Auto / RS-232 Config/Access Control / Local) on the KE6940AIT means commissioning and access-control integration don't require network connectivity to the management plane — a real advantage in air-gapped or segmented deployments.
• Active Firmware Maintenance (v1.8.173, April 2026): A firmware update less than two months old signals an actively supported product line — relevant if you're planning a multi-year deployment and need confidence that security patches will keep coming.

Deployment Considerations:

• The shared firmware package between KE6900AIT (single display) and KE6940AIT simplifies version management if you're running both variants in the same facility — one update file covers both.
• Humidity tolerance tops out at 95% RH non-condensing: this is a controlled-environment device. Do not place it in server rooms with cooling failures or unconditioned spaces — condensation risk is real at the ceiling of that spec.

The KE6940AIT is the right pick for dual-monitor operator stations in physical security operations centers or broadcast control rooms where the source hardware must be centralized but the operator workspace needs full WUXGA on both screens with imperceptible input lag.
