Page 13: Introduction
SERVSWITCH ™ DUO EXTENDER 2. Introduction The ServSwitch™ Duo Extender is a high-performance IBM ® PC compatible keyboard-, monitor-, and mouse-extension device that you can use to connect a distant user station to a ServSwitch™ Duo. The Extender is linked to the Duo with twisted-pair cable, preferably rated Category 5. -
Page 14: The Complete Extender Package
2.2 The Complete Extender Package Along with your ServSwitch Duo Extender, you should have received: • The Extender’s power supply. • The power supply’s input cord. • This manual. If you didn’t receive everything, or if anything arrived damaged, contact Black Box right away. -

Page 16: Installation
CHAPTER 3: Installation 3. Installation 3.1 What You Will Need These things must be in place before you can install your ServSwitch™ Duo Extender: • Four-pair (eight-wire) twisted-pair cabling rated to at least Category 5. This should be long enough to reach from your Extender to the ServSwitch Duo, up to a maximum of 200 meters (655 feet). -
Page 17: Placement
SERVSWITCH ™ DUO EXTENDER • If you’re connecting a local CPU to the KV6EXT-R2 Extender, you’ll need VGA and PS/2 extension cabling. We recommend our bonded three-to-three extension cable EHN408, which has VGA and PS/2 keyboard and mouse strands all in the same cable. However, you can also use separate VGA and PS/2 extension cables such as EVNPS05 and EVNPS03. -
Page 18: Connecting Your Devices
CHAPTER 3: Installation 3.3 Connecting Your Devices First make sure the power supply is unplugged and disconnected from the ServSwitch Duo Extender. 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 5.9.) You don’t have to connect anything to ports on the Extender that you’re not using. - Page 19 SERVSWITCH ™ DUO EXTENDER Optional user station User station directly attached to directly the Duo’s user port #1 attached to CPUs attached to the (shares access with the Duo’s Duo system Extender station) user port #2 SERVSWITCH DUO Category 5 interconnection cable Optional local CPU...

Page 22: Configuration
CHAPTER 4: Configuration 4. Configuration To configure your ServSwitch™ Duo Extender system, first you’ll need to configure any attached PC (if the Extender is a KV6EXT-R2), as directed in Section 4.1. Then you’ll need to configure the Extender itself, as directed in the rest of this chapter. -
Page 23: Configuring The Extender
SERVSWITCH ™ DUO EXTENDER 4.2 Configuring the Extender The ServSwitch Duo Extender has a large number of configuration options. You’ll set different options using one of two different methods: • Which keyboard-character combination the Extender recognizes as a keyboard command is controlled with the Extender’s eight-position DIP switch. See Section 4.2.1. - Page 24 CHAPTER 4: Configuration Top of Extender Bottom of Extender Possible Settings of DIP-Switch Positions 6 through 8: All OFF: Hotkeys = [Ctrl] + [Alt] (default) DIP-Switch Positions 1 through 5 6 & 7 OFF, 8 ON: are reserved for future use; leave Hotkeys = [Ctrl] + [Shift] them set to OFF 6 &...

Page 25: Using Configuration Mode
SERVSWITCH ™ DUO EXTENDER 4.2.2 U SING ONFIGURATION 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 [Alt], press [Ctrl] + [Alt] + [Enter] to activate configuration mode. - Page 26 CHAPTER 4: Configuration 3. Use any of these keys to “tune” the Extender’s video compensation: [Home] sets video compensation to zero. [Pg Up] increases the video compensation coarsely (in large increments). [↑] (up-arrow) increases the video compensation finely (in small increments).

Page 27: Keyboard Commands
SERVSWITCH ™ DUO EXTENDER 4.2.2.B Issuing Other Configuration-Mode Keyboard Commands While the Extender is in configuration mode, it is also possible to enter a number of other keyboard commands that you can use to configure advanced options on the Extender. (There are also commands for such functions as displaying the Extender’s firmware revision, restoring a disconnected mouse port, and resetting all of the keyboard-controlled configuration options to their factory-default states.) Most of these commands consist of pressing a letter key, then a number, then... -

CHAPTER 4: Configuration • [F] [1] [Enter] = Display firmware version (see Section 6.4) • [F] [8] [Enter] = Reset to factory defaults (see Section 6.3) When you finish entering configuration commands and/or adjusting the Extender’s video compensation (see Section 4.2.2.A), press [Enter] to quit configuration mode and return to normal operation. - Page 29 SERVSWITCH ™ DUO EXTENDER Don’t worry if you type the password incorrectly; you can always re-enter it, even if you’ve exited and re-entered configuration mode. If you discover that you messed up entering the password or that you can’t remember what the password is only after someone locks the Extender, you can erase it by selecting “Clear UTP Extender Password”...

Page 32: How The Extender Uses The Keyboard Leds
CHAPTER 5: Operation 5.3 How the Extender Uses the Keyboard LEDs The ServSwitch Duo 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: •... - Page 33 SERVSWITCH ™ DUO EXTENDER • Password-lockout indication—lightbar flashing. As shown in Figure 5-3, while the Extender is locked and waiting for the user to enter a password (see Sections 4.3 and 5.1), it alternately lights the Num Lock/Scroll Lock LED pair and the Caps Lock LED on the keyboard.

Page 35: Contending For Control Of Duo-System Cpus
SERVSWITCH ™ DUO EXTENDER 5.5 Contending for Control of the Duo-System CPUs The user station at the ServSwitch Duo Extender contends with the user stations directly attached to the Duo system for keyboard and mouse control of the Duo system’s CPUs. While a user at one station is in control of a CPU, the Duo system won’t accept keyboard or mouse data for that CPU. -

CHAPTER 5: Operation 5.6 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. If you have a local CPU attached to the full KV6EXT-R2 Extender, it is necessary for the Extender to be powered on during this sequence so that it can give the CPU the required responses and keep track of the modes and settings requested by the CPU. -
Page 37: Keyboard Control: Hotkey Commands
SERVSWITCH ™ DUO EXTENDER 5.7 Keyboard Control: Hotkey Commands NOTE On the basic KV6EXT-R2 Extender, or when the Duo-system CPU is selected on the full KV6EXT-R2 Extender, you won’t use any of the Extender’s own hotkey commands to switch to a different CPU in the Duo system. - Page 38 CHAPTER 5: Operation • Use {Hotkeys} + [0] to select nonexistent “CPU zero.” This causes the Extender to (a) stop lighting its CPU LEDs, (b) disable keyboard and mouse input to any CPU (although Extender commands will still work), and (c) shut off the video output to the attached monitor.

CHAPTER 5: Operation 5.9 Hot-Plugging a PS/2 Mouse or Mouse Port into the Extender or Re-Enabling a Disconnected PS/2 Mouse Port (KV6EXT-R2 with Local CPU Only) It is advisable to switch off any local computer that you’re going to connect to the full KV6EXT-R2 ServSwitch Duo Extender before you install it. - Page 41 SERVSWITCH ™ DUO EXTENDER To restore lost mouse movement on a local CPU directly connected to the Extender: 1. If you’re working with the Duo-system CPU, select the local CPU instead. 2. Enter configuration mode (see Section 4.2.2) by pressing the hotkeys followed by [Enter].

Page 42: Troubleshooting
Section 6.3. If nothing seems to help, get the Extender’s firmware-revision level as described in Section 6.4 if possible, then call Black Box Technical Support as directed in Section 6.5. If you need to ship your Extender, see Section 6.6. - Page 43 SERVSWITCH ™ DUO EXTENDER 5. Make sure that (a) the mouse and computer were both connected to the Extender before any part of the system was powered up, and (b) the Extender was powered ON before the attached computer. If you’re not sure whether this was the case, then (if it’s possible to do so) power everything down, make sure all cable connections are correct and secure, power up the Extender, then power up all attached computers.
