Adder XD612P-DP-US – Dual-Head DisplayPort KVM Extender Pair

Product Overview

The Adder XD612P-DP-US ADDERLink XD612 is a high-performance single or dual-head DisplayPort KVM extender pair that transmits HD video, USB 2.0 HID, and audio on a single CATx or fiber cable. Using DisplayPort 1.2 Multi-Stream Transport (MST), one connection at the transmitter drives one or two displays at the receiver — up to 1920x1200 @ 60Hz per head with 4:4:4 chroma sampling. As a dual-monitor KVM extender over CATx or fiber, it reaches 100m over CAT6 and up to 4km/2.5 miles over single-mode fiber, built for control rooms and enterprise desks that demand ultra-low latency.

Product Description

The XD612 was developed for enterprise organizations and high-pressure control rooms, combining true plug-and-play simplicity with real-time HD KVM extension. The transmitter takes a single DisplayPort 1.2 input from the host — dual-head operation rides on MST, so no second graphics output is consumed — and a local pass-through video port lets a monitor remain at the computer side.

Extension runs over a point-to-point protocol with adaptive video stream compression at 5Gb/s on CATx or 10Gb/s on fiber, keeping latency imperceptible for operators. Both RJ45 and SFP+ ports are fitted on each unit, so installers can choose CAT6 (100m/328ft), CAT5e (50m/164ft), multimode fiber (300m/984ft), or single-mode fiber (4km/2.5 miles) without changing hardware.

Audio handling is comprehensive: two channels of 24-bit/192kHz PCM are encapsulated with each video signal, USB audio runs at 24-bit/96kHz, and analog line in/out plus microphone and headphone/speaker connections operate at 24-bit/96kHz. Adder's USB True Emulation ensures reliable computer boot-up, with emulated USB 2.0 supporting any full or low-speed HID — keyboards, mice, graphics tablets, jog shuttles. RS232 passes between the units at up to 115,200 baud with RTS/CTS flow control, and intelligent EDID management feeds the true monitor characteristics back to the host.

The pair ships complete with two power supplies, DisplayPort and USB cables, and a quick start guide — zero configuration required. Browse matching rack kits, SFP+ optics, and cabling in our Adder Technology collection at Creation Networks.

Key Features

• Single or Dual-Head over One Cable — DisplayPort MST carries one or two 1920x1200 @ 60Hz displays, USB 2.0 HID, and audio on a single CATx or fiber link.
• Copper and Fiber Flexibility — Both RJ45 and SFP+ ports are built in: CAT6 to 100m, multimode fiber to 300m, single-mode fiber to 4km.
• Ultra-Low Latency — Point-to-point protocol with 5Gb/s CATx or 10Gb/s fiber adaptive compression keeps control real-time.
• USB True Emulation — Ensures reliable computer boot-up and supports full and low-speed USB HID devices through four receiver ports.
• Comprehensive Audio — 24-bit/192kHz PCM with video, 24-bit/96kHz USB audio, and analog line/mic/headphone support.
• Local Pass-Through Video — A monitor can remain connected at the transmitter side for rack-side maintenance.
• RS232 with Flow Control — Serial passes between units at up to 115,200 baud with RTS/CTS.
• Plug and Play — Delivered zero-config; works immediately with no drivers or software on any known operating system.

Typical Applications

• Broadcast studio — dual-screen edit and playout positions fed from machines in the central apparatus room.
• Government space — hardware-level extension that keeps computers in secured areas with full desktop response at the user position.
• Auditorium — presentation and show-control PCs racked remotely with operator control over house fiber or CATx.
• Boardroom — silent user position with the host computer relocated out of the room.
• Training room — instructor stations extended from a protected equipment closet over structured cabling.

Frequently Asked Questions

Does dual-head mode need two outputs on my computer?
No. The transmitter takes a single DisplayPort 1.2 connection and uses Multi-Stream Transport (MST) to deliver two independent displays at the receiver.

Which cable should I run?
CAT6 is recommended for copper installs (100m, limited to two short patch connections with CAT6-or-better patch cables). For longer paths, use SFP+ fiber modules: multimode to 300m or single-mode to 4km.

Are the fiber modules included?
No. SFP-SM-LC-10G (single-mode) and SFP-MM-LC-10G (multimode) modules are sold separately; the RJ45 copper ports are built in.

Can I keep a monitor at the computer rack?
Yes. The transmitter provides a local pass-through video output for rack-side maintenance and monitoring.

What USB devices work at the desk?
Full and low-speed USB HID devices — keyboards, mice, graphics tablets, jog shuttles — connect to the receiver's four USB Type A ports with Adder's True Emulation for reliable boot-up.

Is any software required?
None. The XD612 ships zero-config, is transparent to the host, and works with all known operating systems.
