Description
The CK4-PS104C is a high-assurance secure 4-port DisplayPort KVM switch designed for environments that demand strict data isolation and reliable multi-system control. Built to meet NIAP Protection Profile requirements, this solution ensures secure switching between up to four computers while preventing data leakage across channels.
Supporting up to 4K resolution at 60Hz, the unit delivers crisp, high-quality video performance alongside integrated audio switching. The built-in preview screen enhances operational efficiency by allowing users to monitor connected systems before switching, reducing errors and improving workflow in mission-critical settings.
Equipped with a dedicated CAC (Common Access Card) port, the CK4-PS104C enables secure authentication workflows without compromising system isolation. USB emulation ensures seamless keyboard and mouse switching, while robust hardware design and compliance certifications make it ideal for government, defense, and enterprise security environments.
