The AdderLink XD641 is a high-performance KVM extender that delivers real-time, lossless single-head DCI 4K60 video (4096x2160@60Hz with 24-bit color and 4:4:4 chroma), full USB 2.0 HID emulation, bi-directional audio, and RS232 serial control over a single CATx or fiber link up to 100m/4km, ensuring a native desktop experience without latency or artifacts. Key benefits include plug-and-play simplicity with zero drivers or configuration, support for up to four HID devices like mice, keyboards, and graphics tablets for seamless peripheral control, and EDID management for optimal monitor integration—enhancing productivity in remote access scenarios while minimizing setup time and cabling complexity.

Constructed with robust, fanless metal enclosures for reliable rack or desktop deployment, both transmitter and receiver units measure 186mm x 39mm x 148mm, with the transmitter weighing 1.29kg and receiver 1.24kg. Multi-color status LEDs provide easy monitoring, and the included 12V 18W PSU ensures efficient, low-heat operation across diverse environments.

Ideal for mission-critical control rooms, broadcast studios, and enterprise IT workstations, it excels in applications such as secure remote computer access, multi-operator switching, and serial device integration. Fully compatible with all operating systems, Adder's XD series ecosystems, SFP+ fiber modules for extended reach, and DisplayPort 1.2 monitors, it supports local transmitter monitoring for uninterrupted on-site viewing.
