SDHN-4D-P: Ultra-Secure KVM SwitchingMade In America

The SDHN-4D-P is a 4-port, dual-head DisplayPort to HDMI Secure KVM switch with a dedicated CAC port and support for 4K (38402160 @ 30Hz) resolution video.The SDHN-4D-P allows users to control KVM (Keyboard, Video and Mouse) operation on up to four computers with HDMI monitors. It features mechanical, electrical and optical signal isolation to prevent hacking and data leakage in environments where security is paramount.

With the SDHN-4D-P, all data relays are controlled by inverted signals, shielding connections from outside intrusion by forcing them each to work one at a time. Each port uses its own isolated data channel and each unit features non-reprogrammable ROM to better protect the switch's functions. Better yet, the SDHN-4D-P offers the highest security when accessing classified and public networks over the internet through these isolated connections. By isolating connections between networks, the SDHN-4D-P ensures no data is leaked between secure ports and the outside world.

The SDHN-4D-P has clearly marked front-panel buttons for controlling the device, so securely switching between sources is always simple. For high-grade secure switching made easy, look no further than the SDHN-4D-P.

Question: Will the SDHN-4D-P switch support a 30-50ft HDMI output cable with signal boost?
Answer: Thank you for your inquiry,

You can indeed extend the HDMI output of the SDHN-4D-P KVM Switch with a signal booster.

For video only extension, you can use 1-2 CatX / Fiber based HDMI Video Extenders or HDMI cable Boosters / Repeaters. Two extenders would be required for Dual Monitor.

If you would like to extend the USB for Keyboard / Mouse / CAC as well, you can use a HDMI KVM Extender, like the Rose CRK-1DTXT-HD6, with a second optional HDMI Video Extender for Dual Monitor KVM extension.

If you need 4K resolution support, make sure to pick extenders which support 4K.
