how to install Black Box ServSwitch Dual DVI CATx KVM Extender, USB
Setting up the ServSwitch Dual DVI CATx KVM Extender is a straightforward process designed for quick deployment in professional environments. Begin by planning the layout of the two units: place the transmitter near the host computer and the receiver near the remote console. Use standard CAT5, CAT5e, or CAT6 Ethernet cabling to connect the two units, ensuring the cable runs are within the 400-foot maximum distance for reliable signal integrity. Power up both units using their respective power adapters, or as directed by the product’s installation guide if a central power source is available.
- Connect the host computer’s DVI-D video output to the transmitter’s DVI input. Attach the host keyboard and mouse to the transmitter’s USB ports, ensuring they are recognized as standard HID devices. If your setup includes a local console, connect its DVI display to the transmitter as well, maintaining the same USB connections for local control.
- Run a CAT5/5e/6 cable from the transmitter to the remote receiver. Make sure the cable is properly terminated and secured to prevent interference or damage. Keep the cable away from high-power lines and metal obstructions to preserve signal quality.
- At the remote end, connect the CAT5/5e/6 cable to the receiver. Attach the remote monitor to the receiver’s DVI input and connect the remote keyboard and mouse to the receiver’s USB ports. This arrangement enables the remote console to access the same host resources with minimal latency.
- Power-on sequence: turn on the host computer first, then supply power to the transmitter and receiver. Allow the system to initialize and verify that the remote monitor displays the desktop correctly and that keyboard and mouse input are responsive at the remote end.
- Configuration and testing: adjust the display resolution to 1920 x 1200 at 60 Hz if needed, and confirm the color depth automatically negotiates to the optimal 18/21-bit mode. Test keyboard shortcuts, multi-button mouse actions, and any USB peripherals that you plan to use across the extended connection. If you require dual-console use, verify each console is operating independently and that the KVM switch handling is correctly configured in your software or hardware environment.
Tips for optimal performance: keep your CAT cable runs as direct as possible with minimal bends, and avoid running data and power cables in parallel to reduce electromagnetic interference. If you experience any edge artifacts or intermittent signal loss, re-check cable integrity, reseat connectors, and confirm that the distance is within the supported range. Firmware updates, when available, should be performed using the manufacturer’s guidelines to preserve compatibility with your operating environment and connected devices.

Fantastic Shoe for the Price
Size: 9.5 Wide, Color: Wingtip Black
Okay, I’m used to spending big bucks on men’s dress shoes. I’m talking $300 plus for American made shoes. They are recraftable (resole-able) for another $100 each time.
But since Covid, I don’t go to the office as often. One of my black dress shoes needs to be re-soled, and it will be. Just not now.
So I ran into these shoes on Amazon. It’s hard to argue with the price. Literally 10% of what I have been paying. So, are these shoes 90% lower in quality?
The short, simple answer is, surprisingly, no. Just the opposite.
Upon receipt, I inspected them carefully and they looked pretty darned decent. I was looking for any excuse to plop them back in the box and return them. I couldn’t find anything.
I appreciate that the leather upper is smooth and mildly shiny. This is a wing tip style shoe, so I’m impressed that the extensive stitching was evenly spaced. The leather detailing that I expect on a wing tip is also all there.
Inside the shoe, it is lined from the toes all the way to the heel box… nice! And that leather feels surprisingly supple. That is something I would expect on a much more expensive shoe. But definitely not at this price point.
Hmm.
I even liked the wax laces they chose. They are a little thicker and have more than adequate length. The shoe’s eyelets have interior facing metal grommets to protect against stretching and tear out of the leather and helps protect the laces against friction wear, as they are tightened and loosened over time. Now having that detail, at this price point, has raised both of my eyebrows.
Double hmm. Now I am really impressed.
The only thing that I didn’t like was that the stitching—that joins the uppers to the sole—is white. I needed to polish these shoes anyway, so I figured I’d see what would happen if I put black polish on the stitching.
I’m happy to say that the uppers shine up very nicely, to a high gloss. This was done with just a little bit of buffing, using a traditional horse hair bristled brush. And followed by a buffing cloth. Although I didn’t do it, the leather is smooth enough that I probably could have spit shined them.
And those pesky white stitches on the top side of the soles? Well I’m happy to report that they are now definitely black.
Turning the shoe over, I can visually see a lump where the shank is supposed to be. That’s a good thing. Not all shoes have a shank. It helps to support the arch. That’s another nice detail. I am expecting the shank to be plastic at this price point. So I am utterly shocked to report to you that a magnet sticks to the bottom of the shoe. That shank is steel! Now I am amazed! We’re talking mind blown, Purple smoke everywhere.
Speaking of details, I was very surprised to see the nicely done wing tip detailing, from on top of the shoe, carried over to the bottom of the sole. Wow. I have never seen that before. That’s surprising.
Now it is important to point out that the sole is some man made material. Definitely not leather. But that’s okay. Especially in the wet, leather wears out quickly, if you don’t wear rubber over shoes. One less thing to fuss about.
The heel itself has a band/layer of rust brown material sandwiched between black layers. I wonder if that is a cork or bamboo material? Having walked in these shoes, on concrete and tile floors, last week, there is a noticeable level of cush, or give. They will definitely not to be confused with sneakers. But for dress shoes, this is a pleasant and surprising experience.
The first day, I wore them at home, over the weekend and I’m glad I did that. They needed time to adjust to my feet. Any dress shoe that I have ever worn needs that.
But after that, these shoes have been pleasant enough to walk around in at work.
I’d have to say that these shoes give me at least 90% of what I would expect from my $300+ shoes for around 10% of the cost.
In my estimation, at their current price point, they constitute an excellent deal.
And especially if you are just breaking into the business world and need a good pair of interview shoes, these are definitely respectable… just be sure to put black polish on the white stitches.
Oh, BTW, I have wider feet and I ordered the shoe wide. After the initial stretching, they fit nicely.
So, in the final analysis, what do I think? I have to say, yes, these shoes definitely get my recommendation. Especially if price is a huge factor, then these shoes constitute an excellent deal.

Wow. Very impressed with these.
Would purchase again.
Comfortable enough for my teenage son, my husband and I very impressed with their look. Great for any special occasion.
Ours appear to be all leather. Even the sole. These will last a lifetime if cared for.

Great shoes
Size: 10 Wide, Color: Brown, Size: 10 Wide, Color: Brown
This shoe is incredibly comfortable and durable.
I work in custodial work as management. However, sometimes I have to help my team when we are low manned. Just recently I had to help my team auto scrub a restroom. My shoes felt lightweight and were completely easy to clean. I was worried I would be slipping on sudsy water. To my surprise, these shoes gripped on to the floor nicely.
I love the versatility of having a working shoe with the great style Bruno Marc provides. The shoe is breathable and true to size. I ordered the black pair as well and have had them for about 3 months. Highly recommend these amazing shoes.
