Question: I don't need audio or RS232. Is there a NIAP certified version of this 4K 30Hz DisplayPort, USB, Audio & RS232 KVM Extender without those features?
Answer: Thank you for your inquiry,

While NIAP Certification does not really apply to accessories like KVM Extenders, most local KVM Extenders are naturally suitable for classified or unclassified federal government applications. This also applies to many other KVM accessories, like most Rack Monitor Console Drawers, Extenders, and KVM Cables. Most of these devices do not emulate signals, and for the ones that do, they are disposable after resetting local memory.

Here are a few different DisplayPort KVM Extender options for your application:
  1. The SmartAVI DPX-XT is similar to this model but without RS232. We don't currently have a similar extender without Audio; The SmartAVI DPX-XT model, or this SmartAVI DPX-1P-Plus model, would likely be the best options for your application.
  2. For longer extension distances, or more advanced user rights & settings, you may be interested in the Adder ALIF4021P instead. Note, the even though it's an Over IP network extender, the ALIF4021P can also be used point-to-point without going over the IP network.
  3. For a dual-monitor application, or for the option to add a second DP video source later on, the Adder XD522 or the Adder ALIF4021P would be your best options.
