X2-SILVER-P - AdderLink X2 Silver. PS/2 KVM & RS232 CATx Extender. 300 Mtr KVM extender transmitter & receiver pair with IEC PSU (SERIAL Extender )

ADDERLINK X SERIES X2-SILVER/P-UK Keyboard, video, mouse and RS232 extender giving sharp, bright and ultra high-resolution video images at distances up to 300m (1000ft) KVM Extension is used in a wide variety of scenarios to provide direct remote access to computers in environments where it is either inhospitable or impractical to place both the machine and control console in the same place. Past applications for these products are as diverse as data centres, broadcast studios, financial institutions and ship navigational systems. The AdderLink X2-SILVER extends very high quality video, keyboard, mouse and transparent, full speed RS232 up to 300m/1000ft over Category 5 or higher CATx cable. Building on the hugely successful AdderLink X Series, the AdderLink X2-SILVER has been redesigned to significantly improve the performance, specification and value for money whilst retaining industry-leading rack densities and a modular and flexible solution. Increased video performance A significant improvement of the AdderLink X2-SILVER is the increased distance over which video can be transmitted and the very high resolutions that can be achieved at these distances. Industry leading resolutions of 1600 x 1200 are achievable at 200m/650ft and 1280x1024 at 300m/1000ft. For these distances and resolution to be achieved several engineering challenges were overcome; Video compensation When transmitting video signals over extended distances there is an inevitable degradation of the signal and it is necessary for any KVM over CATx extender to compensate for this. How this is implemented greatly affects the quality of the image and the AdderLink X2-SILVER applies a high level of signal compensation that allows for a greatly increased range of very smooth and fine adjustments. Brightness control Another consequence of extending video over long distances of CATx cable is a dimming of the image. Sometimes this can be corrected by brightness controls of the monitor but the range of correction offered by the monitor may not be sufficient. The AdderLink X2-SILVER offers its own brightness correction to ensure that the image is crisp, clear and bright, regardless of the distance. Integrated De-Skew Video signals are transmitted as separate Red, Green and Blue (RGB) signals and KVM over CATx extenders use one of the 4 pairs in a CATx cable for each colour. Because of the way in which CATx cables are constructed, specifically Cat5e and Cat6, each pair length can differ from another meaning that one colour can take longer to arrive than another resulting in colour splitting effects (skew). The user sees this as colour shadows on high contrast screen images. The skew adjustment works by delaying or advancing particular colour signals so that they are delivered to the monitor at precisely the same time. The AdderLink X2-SILVER has integrated skew correction with a 300MHz bandwidth, meaning that it is more than powerful enough to negate the negative effects of the skew. Emulated DDC Display Data Channel support is an area that is often ignored on extenders and KVM switches in general. Display Data Channel is a communication standard that allows a computer monitor to inform a video card of its capabilities. The video card can then configure itself to present an image to the monitor in the most efficient way. Unless a device actively supports DDC this communication cannot take place. Sometimes this is just inconvenient and requires users to manually configure display options. Without this circuitry, some well known high performance video cards cannot be used at high resolutions.
