Question: This product have UL certificate ?

Question: I require a dual dvi screen extender. what do you suggest.
Answer: Thank you for your inquiry. Without knowing more about your particular project, it would be difficult to recommend an appropriate solution. Please call us at 1-877-586-6654 to discuss your project further.

Question: Does this support/refresh/pass through I2C/EDID or does it cache the information once?
Answer: Thank you for your inquiry,

I have confirmed with SmartAVI that the EDID/I2C emulation within the FDX-3000S pings the display on connect, and then caches that information - so it is not actively pinging the display.

If you would like a recommendation based on your setup, please feel free to contact your KVM Switches Online sales representative directly at 1-877-586-6654, at, or via our online Chat functionality.

Question: Do these kvm extenders support CAC enabled keyboards for government usage?
Answer: Thank you for your inquiry,

The SmartAVI FDX-3000S features 'Fully Transparent' USB ports which will support any USB device, including CAC enabled keyboards for government usage.

Question: We have experienced an issue with the keyboard & mouse losing communications with the PC. The solution has been to cycle power on the remote KVM switch, rebooting the PC has resolved the issue as well. Can you provide additional support to help to resolve this issue?
Answer: Thank you for your inquiry,

We are sorry to hear of the troubles you are experiencing!

This sounds like it may be due to the remote KVM Switch you are using - Some older or cheaper KVM switches do not feature USB emulation, which ensures that Keyboard & Mouse devices don't get disconnected due to inactivity or switching sources. Please feel free to get in touch with your KVM Switches Online sales representative for an ideal KVM switch for your application.
