8 / 10 Expert Rating

A serious modular KVM built for control rooms that need to scale past 4 computers, overkill for a simple desk setup.

8.2 / 10 Expert Rating

Specify this over the standard SX42PHU-4 only when the installation requires TEMPEST emissions-security accreditation — otherwise the feature set is identical.
