Product Overview

The AdderLink XD642 doubles the video capability of the XD641, extending two DisplayPort heads at up to 4K @ 60 Hz for dual-monitor workstations. Transparent USB 2.0 and an RS232 channel are carried alongside the video streams.

Link options are CAT6 or fiber SFP modules; ATEN-grade clarity is maintained by running the two 4K60 heads over the fiber link, as documented in the official XD642 installation manual (MAN-000008) available from adder.com.
