CHAPTER 2: Introduction 2.4 Safety Concerns As you prepare to install the ServSwitch Wizard Extender, please keep these things in mind: • The Extender is for use in dry, oil-free indoor environments only. • Make sure that the rated current draw in amperes of all of the devices plugged into the same extension cord, outlet, or circuit as your Extender equipment does not exceed the rated current in amperes of the cord, outlet, or circuit. • Do not attempt to service the Extender yourself.
SERVSWITCH™ WIZARD EXTENDER 3. Installation 3.1 What You Will Need These things must be in place before you can install your ServSwitch™ Wizard Extender: • Four-pair (eight-wire) twisted-pair cabling rated to at least Category 5. This should be long enough to reach from your Extender transmitter to the receiver, up to a maximum of 200 meters (655 feet). Other specifications for this cabling are given in the Appendix.
CHAPTER 3: Installation • If your computer CPU is farther than 2 m (6.5 ft.) from your Extender transmitter: One or more cables to replace or extend the included cable for connecting the CPU to the transmitter, up to a maximum distance of 5 m (15 ft.). You can use VGA and PS/2 extension cables such as EVNPS05 and EVNPS03. To attach a CPU with a PC/AT keyboard port, you’ll need a PS/2 to PC/AT keyboard-port adapter such as product code FA212.
SERVSWITCH™ WIZARD EXTENDER 3.2 Placement NOTE If you’d like to put an Extender module in a space in which its rackmount-enabling endplate doesn’t fit well, or if you need to remove its endplate for whatever other reason, you can do so by unscrewing the two end-mounted screws that hold it on.
CHAPTER 3: Installation You can cover one (ACU5003) or four (ACU5004) empty slots in the chassis using our Blank Chassis Panels. The ACU5003 Single Blank Panel comes with one (ACU5003) or two screws that you’ll use to secure it to the chassis in the same way you’d secure a module. The ACU5004 Quad Blank Panel should be secured with one screw in the upper left corner and one screw in the upper right corner.
SERVSWITCH™ WIZARD EXTENDER 3.3 The Installation Procedure First make sure the power adapter is unplugged and disconnected from the ServSwitch Wizard Extender’s receiver. Also make sure that (if possible) all of the devices you want to attach to your Extender system are turned off and unplugged. (If you have to “hot-plug” a powered computer into the Extender, see Section 5.6.) You don’t have to connect anything to ports on the Extender that you’re not using.
CHAPTER 3: Installation 4. Plug your monitor, keyboard, and mouse directly into the appropriately labeled connectors on the Extender receiver. Or, if you need to place them too far away to plug in directly, plug them into extension cables (see the Appendix) and run the extension cables to the connectors on the receiver. 5. Plug the output cord of the receiver’s power adapter—or a power cord from one of the output jacks of an optional Extender chassis power supply—into the receiver’s power jack. 6.

SERVSWITCH™ WIZARD EXTENDER 4. Configuration To configure your ServSwitch™ Wizard Extender system, first you’ll need to configure any directly attached PC, as directed in Section 4.1. Then you’ll need to configure the Extender itself, as directed in the rest of this chapter. IMPORTANT NOTE Throughout the rest of this manual, the [Enter] designation refers to the main “enter” or “carriage-return” key (often labeled “↵”) on the main section of the keyboard.
CHAPTER 4: Configuration 4.2 Configuring the Extender The ServSwitch Wizard Extender ships from the factory in a default state that’s suitable for most applications, but it has a large number of configuration options. You’ll set different options using one of two different methods: • Set the 8-position DIP switches on the Extender’s receiver and transmitter (see Section 4.2.1) to select automatic or manual video compensation, the keyboard hotkey combination, and other hardware-related functions.
SERVSWITCH™ WIZARD EXTENDER Top of receiver ON OFF Bottom of receiver Position 4 OFF: Automatic video compensation (default) Position 1 OFF: Normal operation (default) Position 4 ON: Manual video compensation Position 2 ON: Upgrade mode for receiver Positions 2 & 3 OFF: Hotkeys = [Ctrl] + [Shift] (default) Position 2 OFF, 3 ON: Hotkeys = [Alt] + [Shift] Position 2 ON, 3 OFF: Hotkeys = [Ctrl] + [Alt] Positions 2 & 3 ON: Hotkeys disabled Figure 4-1. The receiver’s DIP-switch settings.
CHAPTER 4: Configuration • Position 3: If you’ve password-protected the Extender’s receiver and lost the password, move this switch position to ON to put the Extender in configuration mode when it powers up. This will allow you to reset the password, as described in Section 4.4. • Position 4: To reset the Extender without removing power from the receiver or transmitter or disconnecting any of the attached devices, move this switch position to ON, then back to OFF.
SERVSWITCH™ WIZARD EXTENDER 4.2.2 USING CONFIGURATION MODE If hotkeys are currently enabled (see Section 4.2.1), you can put the Extender in configuration mode by pressing the currently selected hotkeys along with the [Enter] key. For example, if the currently selected hotkey combination is the default pairing of [Ctrl] and [Shift], press [Ctrl] + [Shift] + [Enter] to activate configuration mode.
CHAPTER 4: Configuration they’re flashing slowly (to a minimum of one cycle per second for zero distance), the Extender is compensating at a low level suitable for shorter runs of twisted-pair cable. If they’re flashing quickly (to a maximum at which the cycling can no longer be distinguished and it looks like all the LEDs are “half on” for 200 m [655 ft.]), the Extender is compensating at a high level suitable for longer runs of twisted-pair cable. 2.
SERVSWITCH™ WIZARD EXTENDER 4. When you find the best possible picture—and finish entering any other configuration commands (see Section 4.2.2.B)—press [Enter] to save the configuration setting and exit configuration mode. The compensation setting is saved in EEPROM, so it will persist even if the Extender is powered off. For this reason, unless you change your twisted-pair cabling, you shouldn’t need to adjust this setting again. 4.2.2.
CHAPTER 4: Configuration [M] [6] [Enter] = Restore regular mouse [M] [7] [Enter] = Restore IntelliMouse • Set/clear password (see Section 4.4): [P] [Enter] (password) [Enter] = Sets the Extender’s password [P] [Enter] [Enter] = Clears the Extender’s password • [F] [1] [Enter] = Display firmware version (see Section 7.5) • [F] [2] [Enter] = Apply automatic compensation (see Section 7.1) • Report skew (see Section 7.
SERVSWITCH™ WIZARD EXTENDER 4.4 Setting a Password for the Extender There are many situations where access to corporate file servers or sensitive information needs to be controlled. In such circumstances, the ServSwitch Wizard Extender’s transmitter and the attached CPU can be locked away in a secure room or cabinet and controlled from the primary control station attached to the receiver. The Extender also has a password that you can set to prevent unauthorized use.
CHAPTER 4: Configuration If you want to remove the password after setting one, get into configuration mode, type the letter “P”, and press the [Enter] key as before, but then press [Enter] again without typing in any other characters. (If you try to lock the Extender before you’ve set a password, or after you’ve removed the password, the Extender will still blank the video, but it won’t prevent anyone from accessing the CPU.) 4.
SERVSWITCH™ WIZARD EXTENDER 5. Operation This chapter explains the general operation of the ServSwitch™ Wizard Extender. We recommend that you read this chapter carefully before starting to use the Extender; also make very sure you have read the important note at the start of Chapter 4! 5.1 Power-Up Status Under normal circumstances, the ServSwitch Wizard Extender is ready for use as soon as the transmitter and receiver power up.
CHAPTER 5: Operation 5.2 The Extender’s LEDs The ServSwitch Wizard Extender’s transmitter and receiver modules each have one LED mounted on their right sides next to their RJ-45 interconnect ports. There is a similar LED on the right side of the power-supply module. If you have the modules mounted in the Extender Chassis, this LED can be read from the front of the chassis. On all of the modules, the LED has these two states and meanings: • STEADILY LIT = The module is receiving enough power to operate.
SERVSWITCH™ WIZARD EXTENDER 5.3 How the Extender Uses the Keyboard LEDs The ServSwitch Wizard Extender also uses the LEDs on the attached keyboards to indicate various conditions. It will light the Num Lock, Caps Lock, and Scroll Lock LEDs in several different ways: • Configuration-mode indication—rolling sequence. As shown in Figure 5-1, the receiver flashes the Num Lock, Caps Lock, and Scroll Lock LEDs on the attached keyboard in sequence to show that it’s in configuration mode (see Section 4.2.2).
CHAPTER 5: Operation 5.4 Things to Keep in Mind About the Keyboards and Mice PC bootup sequence: When your PC CPUs are powered on, they communicate with any attached keyboards and mice and load the setup parameters required by their particular operating systems. It is necessary for the Extender to be attached and powered on during this sequence so that it can give the CPUs the required responses and keep track of all the modes and settings requested by each of the connected CPUs.
SERVSWITCH™ WIZARD EXTENDER 5.5 Keyboard Control: Hotkey Commands You can control several functions on the ServSwitch Wizard Extender—including CPU connection/disconnection, screen blanking, locking, and entering configuration mode—from the keyboard, using commands triggered with the Extender’s currently selected hotkey combination. All of the hotkey-control commands are invoked by holding down the two hotkeys and then pressing a command key.
CHAPTER 5: Operation Extender is locked, you will have to press [Enter] to clear those characters so that they won’t invalidate the password when you proceed to type it in. • Use {Hotkeys} + [Enter] to cause the Extender to go into configuration mode. See Section 4.2.2. Examples of how to enter these hotkey commands (assuming the hotkeys are [Ctrl] and [Shift]): • To blank the attached monitor’s video: Press and hold [Ctrl] and [Shift], press and release [0] (zero), release [Ctrl] and [Shift].
SERVSWITCH™ WIZARD EXTENDER 5.6 Hot-Plugging PS/2 Mice and Mouse Ports into the Extender and Re-Enabling Disconnected CPU PS/2 Mouse Ports It is advisable to switch off the computer systems that are going to be connected to the ServSwitch Wizard Extender before you install them.
CHAPTER 5: Operation To restore lost mouse movement on a CPU connected to the Extender: 1. At the receiver’s keyboard, select the CPU that has lost its mouse movement. 2. Enter configuration mode (see Section 4.2.2) by pressing the hotkeys followed by [Enter]. 3. To restore a PS/2 mouse connection, issue the [M] [6] [Enter] command. Or, to restore an IntelliMouse connection, issue the [M] [7] [Enter] command. 4. Press [Enter] again to exit configuration mode. 5.
SERVSWITCH™ WIZARD EXTENDER 6. Upgrading the Extender’s Firmware The ServSwitch™ Wizard Extender uses flash-rewritable program memory, and you can upgrade its firmware code by using a PC program to download new firmware into the transmitter and receiver through their keyboard connections. (The transmitter and receiver may be independently upgraded, but we highly recommend that whenever you upgrade one, you also always upgrade the other.
CHAPTER 6: Upgrading the Extender’s Firmware 3. Power down the computer that will be running the upgrade program. 4. Disconnect the twisted-pair cable and any previously connected CPU from the transmitter. 5. Connect the transmitter to the computer that will be running the upgrade program as shown in Figure 6-1. You only need to connect the keyboard strand of the three-to-one cable between the transmitter and the computer. Plug the monitor and mouse directly into their normal ports on the CPU.
SERVSWITCH™ WIZARD EXTENDER 11. Power down the Extender’s receiver and disconnect the twisted-pair cable and any previously connected keyboard from it. 12. Use standard PS/2 extension cable such as product code EVNPS03 to connect the receiver’s keyboard port to the keyboard port of the computer that will be running the upgrade program, as shown in Figure 6-2. (This is correct—the upgrade procedure reverses the normal signal flow on the CPU’s keyboard port.
CHAPTER 6: Upgrading the Extender’s Firmware 18. Reconnect the upgraded transmitter and receiver to each other and to any previously connected equipment.
SERVSWITCH™ WIZARD EXTENDER 7. Troubleshooting If your ServSwitch™ Wizard Extender is not providing sharp video, you can force it to apply automatic video compensation as described in Section 7.1. If one or more of the red, green, and blue colors in the video it’s displaying seems separated or offset, have the Extender report how much skew is occurring (and install the ServSwitch Wizard Skew Compensator, if necessary) as described in Section 7.2.
CHAPTER 7: Troubleshooting 7.2 Reporting and Compensating for Video Skew If you notice that one or more of the primary colors (red, green, or blue) in the video image displayed on your monitor has separated from the others and is horizontally offset from them on your screen—for example, if colored shadows trail bright white objects, as shown in Figure 7-1—then your Extender system might be affected by video “skew.
SERVSWITCH™ WIZARD EXTENDER • If none of the other solutions are practical or if none of them work, you can install a ServSwitch™ Wizard Skew Compensator (product code ACU5100A) between your transmitter and receiver, as shown in Figure 7-2. Receiver To included power adapter Keyboard, mouse, and monitor Skew Compensator CAT5 or higher cables, together totaling up to 200 m (655 ft.) in length Computer CPU Transmitter Figure 7-2. An Extender system with a Skew Compensator installed.
CHAPTER 7: Troubleshooting Before you install or configure a Skew Compensator—or try the other remedies— you might want to have the Extender report how much skew is occurring in your system. To do this, take these steps: 1. Make sure the transmitter and receiver are connected with the twisted-pair cable you want to use.
SERVSWITCH™ WIZARD EXTENDER The first section of the report indicates the length differences between the twisted pairs that are carrying the red, green, and blue color signals. One of the colors will have a reported length difference of “+0.0M”; this is the color carried by the shortest twisted pair. The other reported differences are how much longer the other pairs are than the shortest one.
CHAPTER 7: Troubleshooting 7.3 Other Problems and Possible Solutions Problem: Poor video quality with smearing, fuzziness, or rippling. Possible Solution: Make sure that the video compensation has been set for your system, as described in Sections 4.2.1 and 4.2.2.A. Check for video skew; see Section 7.2. Make sure your Category 5 cable is pinned and paired properly; see the Appendix.
SERVSWITCH™ WIZARD EXTENDER Problem: Compaq MX11800 model integrated keyboard and mouse only: The mouse consistently fails to boot when the Extender is connected to a PC running Windows NT® 4.0 through its PS/2 style mouse port. Possible Solutions: There are three possible solutions to this problem: 1. Use a different type of mouse. 2. Connect the Extender to your NT 4.0 PCs through an adapter and one of the PC’s serial ports rather than through its PS/2 port. 3. Select “CPU zero” while NT is booting.
CHAPTER 7: Troubleshooting 7.6 Calling Black Box If you determine that your ServSwitch Wizard Extender is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable parts. Contact Black Box Technical Support at 724-746-5500. Before you do, make a record of the history of the problem.
