Icron USB Extension Technology | Benefits
Icron, the leader in USB Extension Technology.
All Icron products include their ExtremeUSB suite of features: Transparent USB extension, True plug and play (no software drivers required) and Works with all major operating systems such as Windows, macOS and Linux and Chrome OS.
ExtremeUSB is the most robust and reliable USB extension technology available today and is backed by 20 years of development.
A USB extender system typically consists of a local extender unit (LEX) connected to a host such as a computer, and a remote extender unit (REX) that connects to a USB peripheral such as a keyboard, mouse, flash drive or camera.
These two extender points are joined by transmission link cable such as CAT 5e/6/7 or fibre, to provide a Point-to-Point Connection.
Backed by Scene Double, who have been at the forefront of the professional USB and KVM extension market for over 25 years.

Can I use my own cable with Starling extenders?
No, both versions are designed to work only with the supplied custom 10m cable, ensuring full performance and the proper fire safety rating for your installation.
Is external power required?
Both Starling models are fully bus-powered at each end (with optional DC power input)
