In data communications applications, using products that exceed required capacities is usually not a problem. For example, if a 28.8K modem is required, a 33.6K or 56K model will work... more/see it nowjust fine.
But sometimes, more isnt better. Take KVM extenders designed to expect CAT5 and only CAT5 cable. Youd expect that Category 3 cable wouldnt be effective with these products, and you would be right.
But you may also assume that if Category 5 cable works fine, Category 5e, Category 6, and other higher-capacity cables would work even better. Unfortunately, this isnt the case, and heres why:
KVM extenders from many manufacturers, including ServSwitch CAT5 KVM Extenders, are designed specifically for the Category 5 specs defined by the TIA/EIA standard. Higher-level cables, such as Category 5e, have different characteristics and specifications. Although differences—specifically twist ratios—might seem small, they can have a negative impact on these extenders, which are expecting a true Category 5 transmission.
So with ServSwitch CAT5 KVM Extenders, you can think big with CAT5—just dont think bigger. collapse

Black Box Explains...Digital Visual Interface (DVI) and other digital display interfaces.
There are three main types of digital video interfaces: P&D, DFP, and DVI. P&D (Plug & Display, also known as EVC), the earliest of these technologies, supports both digital and... more/see it nowanalog RGB connections and is now used primarily on projectors. DFP (Digital Flat-Panel Port) was the first digital-only connector on displays and graphics cards; it’s being phased out.
There are different types of DVI connectors: DVI-D, DVI-I, DVI-A, DFP, and EVC.
DVI-D is a digital-only connector. DVI-I supports both digital and analog RGB connections. Some manufacturers are offering the DVI-I connector type on their products instead of separate analog and digital connectors. DVI-A is used to carry an analog DVI signal to a VGA device, such as a display. DFP, like DVI-D, was an early digital-only connector used on some displays; it’s being phased out. EVC (also known as P&D) is similar to DVI-I only it’s slightly larger in size. It also handles digital and analog connections, and it’s used primarily on projectors.
All these standards are based on transition-minimized differential signaling (TMDS). In a typical single-line digital signal, voltage is raised to a high level and decreased to a low level to create transitions that convey data. TMDS uses a pair of signal wires to minimize the number of transitions needed to transfer data. When one wire goes to a high-voltage state, the other goes to a low-voltage state. This balance increases the data-transfer rate and improves accuracy. collapse
Video...How to protect and secure your CPUs with KVM extenders.
Tasked with keeping CPUs or servers secure? Then watch this video tutorial to learn about KVM (keyboard/video/mouse) extension technology. It shows you how to use KVM extenders to put... more/see it nowextra distance between CPUs and user consoles located in public areas. The educational video covers common applications for KVM extenders, such as schools and harsh industrial-control environments, and demonstrates how the extenders maintain high monitor resolutions at even extended distances. Later, the video goes over options for extending KVM signals wirelessly and over an IP-based connection, and spotlights extenders that feature integrated USB hubs and dual-video support. collapse
