描述：

KVM ServSwitch™ Secure (with USB)

The switch you need if your secure and unsecure networks have the newest computers.

TEMPEST Type 2 approved.

Permanently hard wired. Every circuit is soldered down and there is no flash ROM. There is no way to access one CPU from the other or to access one network from the other.

Diodes also provide at least 60dB of isolation to swamp any crosstalk signals between connected computer circuits.

Unidirectional keyboard and mouse signalling thwarts hacking via timing analysis, USB common storage Trojans, keyboard light emissions snooping, and forced malfunctions.

Heavy-duty metal casing is electrically bonded and ensures low emissions.

USB keyboard and mouse connections produce substantially less radiated emissions than PS/2® ones do, making it difficult to snoop data transmissions.

Digital DVI-I video provides even greater security. Its signals are differential, DC balanced, and encoded.

DVI-I video also provides exact video quality and is backwards compatible with older analogue VGA equipment.

True DDC video support.

Clear stereo audio switching circuit for speaker connections eliminates interference and crackle.
