Welcome to the ServSwitch Family!
Thank you for purchasing a BLACK BOX
model! We appreciate your business, and we think you'll appreciate the many ways
that your enhanced keyboard/video/mouse system will save you money, time, and
effort.
That's because our ServSwitch family is all about breaking away from the
traditional, expensive model of computer management. You know, the one-size-
fits-all-even-if-it-doesn't model that says, "One computer gets one user station, no
more, no less." Why not a single user station (monitor, keyboard, and mouse) for
multiple computers—even computers of different platforms? Why not a pair of
user stations, each of which can control multiple computers? Why not multiple
user stations for the same computer?
With our ServSwitch products, there's no reason why not. We carry a broad line
of robust solutions for all these applications. Do you have just two PCs, and need
an economical alternative to keeping two monitors, keyboards, and mice on your
desk? Or do you need to share dozens of computers, including a mix of IBM
RS/6000
®
, Apple
®
multiple users with different access levels? Does your switch have to sit solidly on a
worktable and use regular everyday cables? Or does it have to be mounted in an
equipment rack and use convenient many-to-one cables? No matter how large or
small your setup is, no matter how simple or how complex, we're confident we
have a ServSwitch system that's just right for you.
The ServSwitch family from Black Box—the one-stop answer for all your KVM-
switching needs!
This manual will tell you all about your new ServSwitch Brand Fiber KVM
Extender II or II-SM, including how to install, operate, and troubleshoot it. For an

    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.
  • Page 14: Mouse Compatibility

    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.
  • Page 15: Sound Processing

    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 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.
