how to install Black Box ServSwitch DVI-D USB KVM-over-Fiber Extender, Single-Mode

Follow these steps to set up the extender and begin managing a remote workstation with a local host efficiently:

  • Power off all devices before connecting the extender components.
  • Connect the local host’s DVI-D output to the Extender Transmitter’s DVI-D input, and attach the local USB keyboard/mouse to the Transmitter or designated USB ports as specified by the installation guide.
  • Link the Transmitter to the Remote Receiver using a single-mode fiber cable appropriate for the desired distance and alignment. Ensure both ends are securely terminated and threaded through any routing or conduit as needed.
  • Connect the Remote Receiver’s DVI-D output to the remote monitor and attach the USB keyboard/mouse to the Receiver’s USB ports designated for peripheral access. Verify that the remote workstation is powered and reachable via the extender link.
  • Power up both the local host system and the remote workstation, then verify display clarity, cursor responsiveness, and keyboard input. Adjust display settings if necessary to ensure optimal 1920 x 1080 output and smooth cursor control across the extended link.

Great product
Size: 6FT, Color: Black-20W
Added two of these behind the couch in a wood ledge between the couch and the wall. A template will make marking the cutout easier. You will need to make one as it does not come with the product.

Amazing. A bit of a job to set it up but worth it!
Color: Black, Color: Black
Excellent quality. Sturdy and strong. The screws that come with it are awful. Get yourself some different ones. Takes a while to set it up and get it all measured. I did it while I was setting up my new Flexi-spot E7 Plus standing desk. Wanted to get it all done at the same time. At first. I thought it might be overkill, but I am sooooo glad I did get this. Now my computer moves along with the desk. It looks great. I bet it has improved the air flow around my computer as well. Looks sleek and cool. I might have set it a bit too tight around my case and as a result I have to shimmy it to get it out of the holder if I have to do any work on the computers internals. But at least I know it's secure. My suggestion would be to leave a little bit of slack to avoid this in your setup. Maybe like a 1/4 inch would be ok. The pads should hold it in place anyway. May loosen mine up if I find the time. But it feels totally secure on the desk with no wobble or shaking. Great product. Also I'm a woman in my late fifties 😃and I was able to set it all up on my own. So don't be intimidated ladies, you can do it too. I also bought two of the ultimate set up cable management trays. Great products. Note for anyone from the Ultimate Setup company who might read this. Please provide better quality wood screws and some extra ones) I stripped three of the cheap ones that came with this. And it took forever to drill them in because they weren't strong enough. Then it would be perfect.
