Question: is there a "hot key" sequence to switch between sources? most KVM switches that I have used do have this feature but I can't find any information about this one to verify it
Answer: Thank you for your inquiry,

Secure KVM Switches like the Avocent SC945H do not utilize a physical memory buffer, thus preventing any eavesdropping or key logging attempts (The keyboard and mouse USB buffers are automatically cleared after data transmission). This also means that Secure KVM Switches do not support "Hot Key" functionality. The SC945H can be switched using the physical buttons on the unit. You can also optionally authenticate users over CAC (smart card readers, fingerprint readers and face recognition devices)

Question: Does the SC945H support HDCP
Answer: Thank you for your inquiry,

The SC945 does not support HDCP. While I am currently not aware of a NIAP-certified 'Secure KVM switch' which supports HDCP, if the security certification is not required, you may want to consider the Avocent SV340 instead.

Question: Does the SC945H come with a DC adapter or does it do AC directly out the back?
Answer: Thank you for your inquiry,

The Avocent (by Vertiv) Cybex SC945H has the DC adapter built in - you would plug in a AC cord directly into the unit.

Question: Is there a kit to mount these under a work surface?
Answer: Thank you for your inquiry,

Unfortunately there is no mounting kit available for the SC945H that would allow it to be mounted under a desk.

We do however have other Dual Monitor HDMI KVM switching solutions such as the Raritan DKX3 User Station which would be possible to mount under a work station- Please feel free to contact our sales representatives for a KVM Switch recommendation for your application.
