Adder XD642P-DP-US – Dual-Head 4K60 DisplayPort KVM Extender Pair

Product Overview

The Adder XD642P-DP-US is the AdderLink XD642 KVM extender pair, a high-resolution dual-head 4K DisplayPort KVM extender that carries ultra-high-definition 4K60 video, transparent high-speed USB 2.0, and audio over a single CATx or fiber cable. Built for enterprise organizations and high-pressure control rooms, this dual-monitor KVM extension solution supports two 4096 x 2160 at 60 Hz (DCI 4K60) displays with 24-bit color and 4:4:4 chroma, reaching 100 m over CAT6 copper or up to 4 km over optical fiber. The US suffix indicates US mains cables for both units.

Product Description

The XD642 keeps critical computers in a secure, climate-controlled room while preserving the full desktop experience at the operator position. Its low-latency point-to-point protocol works the moment the link is cabled — no network setup, drivers, or software — making deployment as simple as connecting the transmitter to the host's two DisplayPort 1.2 outputs and the receiver to the operator's displays.

Dual 4K60 operation runs over a fiber link, while dual 2560 x 1600 at 60 Hz is supported over CATx cable — each unit provides both an RJ45 port and an SFP+ cage so integrators can match the medium to the distance and resolution required (fiber SFP modules sold separately). USB 2.0 is handled two ways: True Emulation keeps keyboards and mice instantly responsive, and a transparent high-speed port supports mass storage, webcams, and USB audio headsets.

Audio support is comprehensive: up to eight channels of 24-bit/192 kHz PCM over the DisplayPort connection, plus bi-directional analog stereo at 24-bit/96 kHz with line in/out and headphone connections at the receiver. An RS232 serial channel passes between units at up to 115,200 baud with RTS/CTS flow control, and EDID management reports true monitor characteristics back to the host for correct output without manual configuration. With a 500,000-hour MTBF, fanless receiver design, and rugged metal construction, the XD642 is engineered for continuous duty. Need quad displays instead?

Technical Specifications

Frequently Asked Questions

Do I need fiber for dual 4K60?
Yes. Dual 4096 x 2160 @ 60 Hz operation requires a fiber link via the SFP+ cages; dual 2560 x 1600 @ 60 Hz is supported over CATx copper up to 100 m.

Are SFP modules included?
No. Fiber SFP modules are sold separately so the optics can be matched to your fiber type and distance, up to 4 km.

Can I connect USB drives, webcams, or headsets?
Yes. The transparent USB 2.0 high-speed port supports mass storage and isochronous devices such as webcams and USB audio headsets, alongside the emulated HID ports.

Is host software or network configuration required?
No. The XD642 is a point-to-point extender that operates as soon as it is connected; it is independent of the corporate network.

How does the XD642 compare with the XD C650?
The XD642 delivers dual-head 4K60 from two host DisplayPort connections; the XD C650 pair provides quad-head HD60 (or single 4K60) from a single host DisplayPort using MST.

What operating systems are supported?
All known operating systems; no drivers are installed on the host.
