KVM ServSwitch? Secure Plus (with USB)
Thwart hackers from accessing information with the added security of a built-in card reader
Built-in card reader provides an additional layer of security. Authorised users can access only the computers they are permitted to operate.
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 60 dB 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.
Digital DVI-I video 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.
