The IPGard 4-Port Dual-Link DVI-I KVM Switch allows users to control keyboard, video and mouse operation on up to four computers with dual-head DVI displays (or HDMI/VGA displays with an optional adapter). It supports native video resolution up to 2560 x 1600 at 60 Hz and can also support up to 4K (3840 x 2160 at 30 Hz) resolutions via an HDMI-to-DVI adapter (available separately). It features a dedicated CAC port and allows users to assign specific peripheral devices to this port. Once a peripheral device has been registered by an authenticated admin, users can then switch the connection between that device and the PC's along with KVM switching. Designed for use in secure defense and intelligence applications, this switch is NIAP PP 3.0 certified and includes security features that meet Information Assurance safe control standards.

Thanks to the opto-isolators that keep the USB data paths electrically isolated from each other, providing high isolation and preventing data leakage between ports. This switch emulates the presence of a keyboard and a mouse for every attached computer through a USB cable, preventing direct connection between the peripherals and the connected computer. It also prevents unwanted and unsecure data from getting transmitted through the DDC lines by means of secure EDID learning and emulation.

The unit is equipped with internal anti-tamper switches, which sense attempts to open the device enclosure. Once the system identifies such an attempt, the unit shuts off connections with all the attached PCs and peripherals, disabling any functionality. The controller of the unit comes with a protection feature that prevents reprogramming or reading the firmware. The enclosure is also protected with a tamper-evident seal to provide a visual evidence if the unit has been opened.
