Can this KVM Switch support a smart card keyboard combination?
Thank you for your inquiry., According to our Avocent contact, this KVM will support a keyboard with integrated CAC reader as long as the keyboard is CCID compliant.

If you have issues installing the driver, please see this Avocent Support Community post:

How can I use multiple monitors at my avocent 440 station?
Thank you for your inquiry. Unfortunately the SC 400 series does not support dual monitors. While the units are dual-link, they are not dual-head. Dual-link DVI provides additional data channels that effectively double the available video bandwidth for increased resolutions.

For a dual monitor system the KVM will require two available video ports on both the target computer and KVM switch itself, for each attached system. The SC 500 series is a comparable dual-head KVM: https://www.kvm-switches-online.com/sc540.html.

Is it really 1.85"H or 1.75"H (i.e., within 1 rack unit)? Is there rackmount kit available?
Thank you for your inquiry. We have seen the height listed by Avocent for this unit as 1.85", 1.875" and 1.9". Unfortunately, it appears this unit will not fit within 1U of rack space.

For the most part, the SwitchView series is considered a desktop KVM. While some of the 8-port models and other subsets (like the SC100,SC200 and SC600 series) come in under 1.75" in height, there is not a specific rackmount kit for any but the SC8PDV.

Can USB extenders be used to put keyboards and mice further away?
Thank you for your inquiry. Unfortunately, the security features of this switch prevent the use of a USB extension device. This switch will only detect mouse, keyboard and CAC reader USB type devices and would not recognize a USB extension device. If it was possible, another potential issue would arise in that the only way to switch target devices is via the push buttons on the front of the switch.
