Welcome to the ServSwitch
Thank you for purchasing a BLACK BOX
appreciate your business, and we think you'll appreciate the many ways that your
new ServSwitch keyboard/video/mouse switch 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
®
Macintosh
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™ Spectra, including
how to install, operate, and troubleshoot it. For an introduction to the Spectra, see

  • Page 20 SERVSWITCH™ SPECTRA • Any monitor you connect to the Spectra needs to be able to support the highest video resolution and refresh rate that either of your CPUs can generate. For example, if one of your computers only needs its monitor to display 640 x 480 pixels at 60 Hz, but the other one needs its monitor to display 1280 x 1024 pixels at 75 Hz, make sure to use a monitor that can display at least 1280 x 1024 pixels at 75 Hz.
  • Page 21 CHAPTER 3: Installation • Some software programs come with special copy- protection devices called “dongles.” These are designed to be inserted between the keyboard and the computer; the programs test for the dongles’ presence to assure that they are being run by their legal owner only.
  • Page 22 SERVSWITCH™ SPECTRA 3.3 Connecting the Monitor, Keyboard, and Mouse The first step in your ServSwitch Spectra installation is attaching your ”user station” equipment (keyboard, mouse, monitor, and—if you want—headphones or speakers).

  • Page 24 SERVSWITCH™ SPECTRA 3.4 About the CPU Cables Now for the CPUs. You could use separate video-, keyboard-, and mouse-extension cables to connect the ServSwitch Spectra to their video, keyboard, and mouse ports, but we recommend using one of our special CPU- Extension Cables instead.
  • Page 25 CHAPTER 3: Installation • The coaxial type, which has EHN408 product codes, contains a thick coax core like cable-TV cable. You might need this if you’re using your computers for video editing, Web design, CAD/CAM, or other things that require good transmission of high- resolution video—especially if the computers are more than a few feet (more than one or two meters) from the Spectra.
  • Page 26 SERVSWITCH™ SPECTRA CAUTION! Avoid running any of these CPU cables too close to fluorescent lights, air conditioners, or other electrically noisy equipment. If you’re not sure about a particular device, check its manual. If the manual says that the device isn’t electrically or magnetically shielded, or warns that it might interfere with or damage sensitive equipment, keep the cables away from it.

This will suspend audio switching, switch the audio to the chosen computer, and “park” audio access on that CPU indefinitely. From that point on, when you select a CPU with [Ctrl] [1], [Ctrl] [2], or [Ctrl] [Backspace], or when you start and stop scanning with [Ctrl] [S] or [Ctrl] [X}, it will switch only the keyboard, video, and...
  • Page 37 CHAPTER 4: Operation Here’s what can happen: PS/2 type mice send control data to CPUs in three- or four-byte “packages.” Sometimes, because of electronic transients, unusual power-up effects, or plugging and unplugging of cables from live equipment, the currently selected CPU in a ServSwitch Spectra system can lose one or two bytes of this control information.
  • Page 38 SERVSWITCH™ SPECTRA The CPU will be thrown out of sync if it has a PS/2 mouse port and it’s in sync when you issue this command. Issue this command two or three more times to get it back in sync again. If you have version 9.01 or higher of the Microsoft mouse driver, the CPU should never get out of sync.
  • Page 39 CHAPTER 4: Operation function, this command is usually more effective than [Ctrl] [N] for clearing up mouse problems.) To do this, press and release the left Control key ([Ctrl]), then press and release the letter [O] (not the number zero). In contrast to [Ctrl] [N], entering [Ctrl] [O] when the mouse is in sync will have no discernible effect on the mouse.
  • Page 40 SERVSWITCH™ SPECTRA The “Identify ROM” command causes the Spectra to send two numbers xy (short for its three-character “x.y” ROM level) to the currently selected CPU as ASCII keyboard data; these characters will be echoed back to your monitor if you are at some type of prompt. (You must be at some kind of prompt or screen capable of displaying typed-in keyboard characters, or you will not see the Spectra’s response.)
  • Page 41 CHAPTER 4: Operation 4.9 Set Scan-Delay Time Enter a “Set Scan-Delay Time” command to set how long, in seconds, the ServSwitch Spectra will pause at each of the CPUs when it’s scanning them. The factory-default setting is 5 seconds. To set a different delay time, press and release the left Control key ([Ctrl]), then type the letter [T] followed by the new delay time in seconds (1 to 15), and press and release [Enter].
  • Page 42 SERVSWITCH™ SPECTRA Similarly, if you’re using a PS/2 wheel mouse with the ServSwitch Spectra, and either of the attached CPUs has a PS/2 mouse port and is running a driver that will handle wheel-mouse data, you should tell the Spectra to output mouse data in PS/2 wheel format to that CPU.

  • Page 43: Troubleshooting

    CHAPTER 5: Troubleshooting 5. Troubleshooting The first three sections of this chapter discuss some of the problems that can arise in a ServSwitch Spectra system and suggest possible causes and solutions. If the trouble you’re having with the Spectra is something you haven’t seen before, or if the trouble seems minor, try the procedures detailed in Section 5.1 and (if that doesn’t work) Section 5.2 before doing anything else.

  • Page 44: Resetting The Spectra

    SERVSWITCH™ SPECTRA 5.1 Resetting the Spectra Sometimes the ServSwitch Spectra might stop operating correctly (or at all) because an error occurs. At other times, the attached keyboard or mouse might become confused. If: • your keyboard gets stuck or begins misbehaving, •...
  • Page 45 CHAPTER 5: Troubleshooting If the affected CPU is running DOS or Windows 3.x, don’t press the reset button if the CPU doesn’t have a mouse driver loaded. Resetting the Spectra will cause the mouse to send data to the CPU, and many DOS/early Windows CPUs will crash if they receive unexpected mouse data.

  • Page 46: Restoring Factory-Default Settings

    SERVSWITCH™ SPECTRA 5.2 Restoring Factory-Default Settings If you’re having difficulty with a ServSwitch Spectra, something that sometimes helps is resetting the Spectra to its factory defaults. Follow these steps: 1. Make sure that at least one powered CPU is attached to the ServSwitch Spectra (it doesn’t matter which port the CPU is connected to).

  • Page 47: Common Problems

    CHAPTER 5: Troubleshooting 5.3 Common Problems 5.3.1 A CPU C ’ ONNECTED TO PECTRA OESN ET A EYBOARD OR OUSE RROR A. First make sure that the CPU is in fact connected to the ServSwitch Spectra and that the Spectra is getting power. (To get enough power to work properly, the Spectra must be cabled to the keyboard port of a powered CPU.) B.
  • Page 48 SERVSWITCH™ SPECTRA F. If swapping cables doesn’t solve the problem, try plugging the CPU into the other CPU port on the Spectra. If the CPU boots when it’s connected to the other port, one or more of the first port’s connectors are probably defective.
  • Page 49 CHAPTER 5: Troubleshooting B. The ServSwitch Spectra might have lost power for less than three seconds. (This can cause the keyboard to lock up.) Disconnect the keyboard and plug it back in. C. The keyboard might simply have gotten a little off kilter. If the Spectra can see the keyboard at all, try reinitializing the keyboard by pressing the reset button (see Section 5.1).
  • Page 50 SERVSWITCH™ SPECTRA 5.3.3 C HARACTERS RONG OR ISSING The keyboard mode that the Spectra is using to send data to the CPU might be wrong. See item D under Section 5.3.2. 5.3.4 Y ’ OUSE RIVER OESN A. To recognize the mouse, the CPU must be directly connected to it, or indirectly connected to it through the Spectra, at boot-up time.

  • Page 51: Mouse Gets Out Of Sync

    CHAPTER 5: Troubleshooting C. Your mouse driver might be old or incompatible with your mouse. Try the latest version of the Microsoft mouse driver. D. If your mouse is a Logitech mouse, the Spectra supports the two-button models but not the three-button models.

  • Page 52: Display Is Fuzzy

    SERVSWITCH™ SPECTRA C. The Spectra’s mouse mode might not be set correctly. See Section 4.10. D. Your mouse must be connected to the ServSwitch Spectra when the CPUs are booted and when mouse applications are run. Try exiting and re-entering your application;...
  • Page 53 CHAPTER 5: Troubleshooting B. Your monitor might not be capable of synching to the selected video resolution or frequency (refresh rate). Try a lower resolution or frequency or a more powerful monitor. C. If the video problem is not centered on the monitor itself, check the monitor cable and the video strand of the CPU-Extension Cable.
  • Page 54 SERVSWITCH™ SPECTRA 5.3.11 O NE OR OTH OF TART INDOWS The usual cause of this problem is that the affected CPUs are set to load a Logitech or other type of mouse driver when Windows starts up. Set the CPU to load the generic Microsoft mouse driver instead.

    APPENDIX B: Surface-Mounting the Spectra Appendix B: Surface-Mounting the Spectra If you want to firmly mount your ServSwitch Spectra on a flat surface—we’ll refer to this as the “mounting surface” in the rest of these instructions—use the included mounting plate. We recommend attaching the plate to the mounting surface with either adhesive material or screws.
  • Page 60 SERVSWITCH™ SPECTRA 2. Attach the adhesive material to the underside of the plate. If you’re using something like double- sided tape that isn’t very thick between its adhesive layers, you might have to attach a single strip to the plate’s middle groove in order for the adhesive to make contact with the surface.
  • Page 61 APPENDIX B: Surface-Mounting the Spectra 1. If screwholes of the proper width, depth, and spacing don’t already exist in the mounting surface, such holes will need to be drilled by an experienced person taking all appropriate safety precautions. The holes in the mounting plate can be used as guides.

  • Page 64: Appendix C: Commands For Advanced Users

    SERVSWITCH™ SPECTRA Appendix C: Commands for Advanced Users C.1 Set Keyboard Mode Some CPUs might require you to set the ServSwitch Spectra to output a different keyboard mode than usual. Keyboard “modes” are electrical signaling protocols that determine how a powered CPU and keyboard interact. A CPU and keyboard must use the same mode in order to work with each other.
  • Page 65 APPENDIX C: Commands for Advanced Users Most CPUs that use keyboard mode 1 or 3 send a “mode command” to the keyboard at power-up, to put the keyboard in the proper mode. A Spectra can use these commands to automatically detect each such CPU’s keyboard mode when you turn on the CPU after it has been cabled to the Spectra.
  • Page 66 SERVSWITCH™ SPECTRA • you don’t know which mode the CPU uses or the port is set for, but the keyboard’s behavior makes you suspect that the port’s setting is wrong. To set the keyboard mode of the currently selected port on a Spectra, press and release the left Control key ([Ctrl]), then type [M] followed by the mode number ([1], [2], or [3]).

  • Page 67: Set Keyboard Typematic

    APPENDIX C: Commands for Advanced Users C.2 Set Keyboard Typematic Most keyboards have an internal seven-bit “typematic” setting, which governs the way the keyboard responds when you hold a key down to force it to repeat.
