Secure 8-Port, Single-Head DP KVM Switch with 4K HD Support

Description: The Secure KVM emulates (simulates) the presence of a keyboard and mouse for every attached computer through a USB cable. Both selected and non-selected computers maintain a constant connection with the unit’s keyboard and mouse emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected peripherals during switching operations. Emulation of keyboard and mouse also prevents direct connection between the peripherals and the connected computers, shielding systems from potential vulnerabilities.The KVM can simulate a generic EDID, allowing it to operate most of the connected DP monitors in the market. Both selected and nonselected computers maintain a constant connection with the unit’s video and EDID emulation controllers, allowing for ultra-fast switching and restricting discovery of newly connected monitors during switching operations. The unit prevents unwanted and unsecure data from getting transmitted between the computers and the display.

Sam Smith - General Dynamics

We were looking for a 1U 19" Rackmount LCD Keyboard console for our Flight Simulation System. KVMSwitchTech promptly responded to all our questions. We purchased several NRKD-KVM-19 Rackmount Console units from them and are very happy with the performance. Keep up the good work.

KVMSwitchTech helped us with a 1080p Rackmount Console with integrated 8 Port USB KVM Switch for our CNC Machines. The product works great and the staff is very friendly. I would recommend this Company.

James Johnson- Lockheed Martin

Knowledgeable, experienced and courteous staff. We needed Fiber Optic Extenders with EMI shielding to avoid interference in signal transfers. KVMSwitchTech worked with us to design a DVI Fiber Optic Extender customized for our application. Thanks for all your help.
