Black Box SI1P-SH-DVI-UCAC 1-Port DVI-I USB KVM Switch CAC

Secure Single-Port KVM for CAC Environments

The Black Box SI1P-SH-DVI-UCAC is a NIAP 3.0 certified KVM defender designed for single-head DVI-I workstations that require Common Access Card authentication. It provides absolute isolation between the connected computer and the console peripherals. This unit targets government or defence users who must prevent data leakage across classification boundaries while operating at resolutions up to 2560 x 1600 at 60Hz.

Verify DVI-I Video and USB 1.1 Peripheral Support

Before ordering, confirm that your source system outputs a DVI-I signal compatible with the 29-pin female connector and that the display accepts the same interface. The switch passes USB 1.1 keyboard and mouse data only through two Type B console ports and two Type A computer ports; higher-speed USB devices will not function. An external 12-VDC power supply is included and required for operation.

Passive Cooling Within 0 to 40°C Range

The device operates without fans, relying on passive dissipation within an ambient temperature range of 32 to 104°F (0 to 40°C) and humidity up to 80% non-condensing. With only a single computer connection and USB 1.1 signalling, power draw remains minimal and acoustic output is silent. Anti-tamper features such as hologram seals and chassis intrusion detection add physical security without thermal impact.
