CHAPTER 2: Introduction 2. Introduction 2.1 Overview There are many KVM extenders available, but until now many of them have used analog image transmission, which inherently degrades image quality (especially over long distances and at high video resolutions). The ServSwitch Brand Fiber KVM Extender II and II-SM is a digital image- transmission system. Video output from a local computer CPU is automatically digitized by the extender’s local unit and transmitted serially to the remote unit on a s

CHAPTER 3: Compatibility and Signal Processing 3. Compatibility and Signal Processing This chapter discusses technical details of how the ServSwitch Brand Fiber KVM Extender II and II-SM process I/O signals, and how that processing affects compatibility with various equipment. 3.1 Video Processing The extender’s local unit contains powerful electronics to process your video signal with superior quality. Video input is digitized as 16-bit data (65,536 colors). The local unit can accept these res

SERVSWITCH™ BRAND FIBER KVM EXTENDER II AND II-SM The brightness and contrast of the video signal are adjusted automatically before digitizing the signal. This ensures the best possible video quality without requiring configuration or adjustment by the user. When the local unit detects that the CPU has switched to a different resolution, refresh rate, etc., it will adjust all digitizing parameters automatically. Only a few seconds later, you will again have a sharp, crisp, and colorful image wit

CHAPTER 3: Compatibility and Signal Processing 3.3 Sound Processing The local unit receives stereo sound input and converts it into a monaural “sum” signal. (The local unit supports standard input-signal levels of 0.7 V [effective eff volts], equivalent to about 2 Vpp [volts peak-to-peak].) This signal is then digitized as 8-bit data by sampling at a rate of about 16 kHz. The remote unit converts the signal back to analog audio and outputs the monaural sound simultaneously on both the left and r
