THE SERVSWITCH FAMILY

Welcome to the ServSwitch™ Family!

Thank you for purchasing a BLACK BOX® ServSwitch™ Brand PS/2 Micro Extender 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® PC, RS/6000®, Apple® Macintosh®,

Sun Microsystems®, and SGI™ compatibles among 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 PS/2 Micro Extender, including how to install, operate, and troubleshoot it. For an introduction to the Extender, see

2.6 How to Use This Guide

This guide describes the installation and configuration of the ServSwitch Brand PS/2 Micro

Extender Series. Although the connection and operation of the system is relatively straightforward, you should consider the following before getting started:

Connection & Compatibility

If you have purchased an Extender Kit, this will contain all the cables required to connect the

Local unit to your PC or KVM switch. The Remote console (keyboard, monitor and mouse) and any audio and serial equipment connects directly to the Remote unit.

If you have purchased a Remote Unit, ensure that it is compatible with your Local unit (see

Compatibility, page 16).

For information about connection and installation, see Installation, page 19.

Interconnection Cable

You will need CATx (any category 5, 5e, 6 or higher) cable, terminated with RJ45 plugs, to connect the Local and Remote units (see Interconnection Cable Requirements, page 20).

Adjusting Video

Video signals become distorted when transmitted over CATx cables. To get the best from your extender system, it is essential that you adjust the Remote unit to optimize the video image quality:

• For experienced users, there is a Quick Setup section at the start of this guide (see page

10).

• For the full procedure, see Remote Unit Configuration & Operation, page 28.

18

INSTALLATION

3. Installation

For first-time users, we recommend that you carry out a test placement, confined to a single room, before commencing full installation. This will allow you to identify and solve any cabling problems, and experiment with the KVM extender system more conveniently.

3.1 Package Contents

You should receive the following items in your extender package. If anything is missing, please refer to Appendix F to obtain Technical Support.

• Extender Remote unit.

• 5-VDC universal power supply for Remote unit.

19

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

3.2 Interconnection Cable Requirements

To connect the Local and Remote units you will need CATx (any category 5, 5e, 6 or higher) cable terminated with RJ45 plugs.

Interconnect cables must be solid-core type. Stranded patch cable will give poor results over longer distances. The pairing of the cable and pinning of its connectors should normally be in accordance with EIA-568B (see Appendix D: Cable Pinning, page 46).

One CATx cable is required for each video channel.

• The Primary interconnect cable connects INTERCONNECT Port 1 on the Local and

Remote units. This carries the main video channel and all data (plus audio/serial).

• The Secondary CATx cable (connected to INTERCONNECT Port 2) carries the second video channel.

In order to send Keyboard, Mouse, Audio and Serial signals to the PC, the

Primary interconnect must be connected.

The Primary interconnect does not have to be connected in order to use the keyboard attached to the Remote unit for setup. However, if the Primary interconnect is disconnected, the keyboard cannot be used for configuration for 15 seconds after disconnection (to maintain data integrity).

With some cables, video performance may be improved by using a crossover patch cable at each end or an alternative RJ45 pin-out (see Appendix D: Cable Pinning, page 46).

20

INSTALLATION

3.3 Remote Unit Installation

To install a Remote unit:

1.

4. Remote Unit Configuration &

Operation

This section describes how to optimize the video signal, configure the Extender system and operate the Remote unit.

For details about flash upgrading and external configuration see Appendix C: Remote Unit:

Flash Upgrading & External Configuration, page 45.

For more information about serial/audio port operation, see Appendix E: Audio/Serial

Ports, page 47.

4.1 Command Mode

During normal use, the Remote console keyboard functions in the usual manner. However, by using a specific ‘hot’ key sequence, you can set the keyboard into a Command Mode. From this, you can use various keys and key combinations to tune the video signal and generally configure the extender system.

To enter Command Mode:

1.

Ensure that you have installed and powered up the system according to the instructions in Section 3.

2.

Press the following key combination on the Remote keyboard:

<Left Control> + <Left Shift> + <F10>

From Command Mode you can use one or more of the ‘hot’ key sequences shown on page 11 to configure the system. The next section gives a full description of the video optimization procedure.

To exit Command Mode:

• Press <Esc> to exit Command Mode and save the configuration settings, or

• Press <Left Control> + <Esc> to exit Command Mode without saving changes made in the current session.

The Remote unit automatically exits Command Mode after 30 sec of inactivity, saves all settings to EEPROM and returns normal function to the keyboard.

28

REMOTE UNIT CONFIGURATION & OPERATION

Status LEDs in Command Mode

In Command Mode, the Remote unit:

• Illuminates the yellow Interconnect 1 LED continuously (see Figure 5).

Note. The Yellow LED on Interconnect 2 is not lit.

• Flashes the status LEDs (Num Lock, Caps Lock, Scroll Lock) on the connected keyboard to indicate the selected video channel (to which adjustments will be applied).

The number of flashes indicates the selected video channel:

Keyboard LED flashes

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

4.2 Adjusting Video

PS/2 Micro Extender Remote units incorporate video equalization circuitry, allowing you to compensate for the loss in image quality that occurs when video signals are transmitted along

CATx cables. At the factory, Remote units are configured to optimize the video signals for

Interconnect cables up to 75ft (25m) in length.

If you intend to use cables of 75–150ft (25-50m) in length:

1.

Ensure that you have installed and powered up the system according to the instructions in Section 3.

2.

Enter Command Mode by pressing the following key combination on the Remote console keyboard:

<Left Control> + <Left Shift> + <F10>

3.

By default, both channels are selected for adjustment and this is indicated by slow flashing of the keyboard status LEDs (Num Lock, Caps Lock, Scroll Lock). If you want to select a single channel press the corresponding numbered key:

Video channel Command Keyboard Status LED action

Channel 1

Channel 2

Both channels

<1>

<2>

<0> (default)

Single flashes

Double flashes

Slow single flashes

4.

Press the following key combination to change the video equalization setting:

<Left Control> + <E>

Note: This command toggles the video equalization setting; repeat the procedure to revert to the original setting for a shorter interconnection cable length [<75ft (25m)].

5.

If you are using one or more flat panel monitors in the Remote console, carry out auto-adjustment as described in the monitor’s documentation. Sometimes manual adjust of clock and/or phase is also required for optimum results and minimization

of jitter.

Technical Note: This video compensation does not correct color separation (skew). Although skew can be an issue on some CATx cables, it would not normally be observed on cables <150ft (50m).

Even so, we still recommend the use of low skew cables with PS/2

Micro Extenders. You can check whether skew is a problem in your system by viewing the test card at: http://www.blackbox.com/tech_support/ts_upgrades/ts_ss.html

REMOTE UNIT CONFIGURATION & OPERATION

4.3 Other Remote Configuration &

Operation Options

The ServSwitch Brand PS/2 KVM Micro Extender Series has additional commands to reset the keyboard and mouse, to restore the factory default configuration, change DDC settings, and to initiate and control a Private mode session (Dual Access models only).

Command Key Sequence

Reset Mouse and Keyboard <F1>

Resets the Remote console’s keyboard and mouse and then automatically exits Command

Mode. You may need to do this if you have hot-plugged a keyboard or mouse and it has not initialized correctly.

Mouse Recovery <F3>

Use this command if you experience erratic movement of the mouse pointer or you have lost mouse movement after hot plugging the Local unit into the CPU. In the case of erratic mouse movement, you may need to enter the command a number of times to re-synchronize the mouse signal. Alternatively, stop moving the mouse for a few seconds and the operating system’s mouse drivers may automatically re-synchronize the signal. If the Local unit has been hot-plugged, this command will issue a request to the OS to initialize the mouse. Use this command with care.

Set Extender To Default State <Left Control> + <F9>

Sets ALL extender settings (video, configuration & DDC) back to the factory defaults and then exits Command Mode.

Toggle Remote Unit Private Mode <Scroll Lock>

Use this command to begin or end a Private Mode session at the Remote console (see page

32).

Toggle Local Video Blanking State <Left Control> + <Scroll Lock>

Use this command to determine whether the Local console monitor will be blanked (default setting) or enabled during a Private mode session at the Remote console.

Disable DDC Emulation <Left Control> + <F2>

By default, the Local unit provides DDC emulation on both video channels. Use this command to disable DDC emulation (see page 32).

Enable DDC Emulation <F2>

Use this command to restore DDC emulation.

Transfer DDC to Local Unit <Left Control> + <D>

Read DDC from monitor connected to Remote Unit video channel 1 and apply to selected video channels in Local Unit (see page 33).

31

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

Private Mode

On dual access systems, a user at one console can lock out the other console by triggering a

‘Private Mode’ function. This prevents the other console from being used even if the twosecond inactivity timeout period expires.

To indicate that the Private Mode session is active, the extender system:

• Slowly flashes the Scroll Lock LED on the user’s keyboard.

• Illuminates all three LEDs on the other console’s keyboard.

• Locks the other console’s keyboard and mouse.

• Displays a blank image on the other console’s monitor. If you want the other console monitor(s) to remain active during Private Mode sessions, use the Toggle Video

Blanking State command.

To cancel the Private Mode, enter Command Mode again and press <Scroll Lock>. This command also closes Command Mode.

DDC Emulation

Modern graphics cards use VESA DDC (Display Data Channel) to identify the capabilities of connected monitors. Some cards will not operate correctly unless they communicate with a

DDC-enabled monitor.

By default, a PS/2 Micro Extender Local Unit emulates a universal monitor (on both channels) and reports that it is capable of all standard screen resolutions and refresh rates.

This ensures that the vast majority of graphics cards and monitors should operate correctly with the extender system.

The DDC emulation can be optionally disabled but this would only be required in special applications.

It is also possible that the default DDC emulation may not report a non-standard graphics mode, for example, if an HDTV monitor is connected. In this case, the DDC from the remote monitor(s) may be read and stored in the Local Unit using the Transfer DDC command (see page 33).

In addition, the default DDC emulation is flash-upgradeable (see page 45).

Always reboot Windows after adjusting a DDC parameter.

32

REMOTE UNIT CONFIGURATION & OPERATION

Transferring DDC Information

To support non-standard screen settings or other features, it is possible to read and store DDC information into the Local Unit directly from the monitors connected to the Remote Unit.

You only need to carry out this procedure once; the Extender Units store the DDC information in non-volatile memory and restore it at power-up.

1.

Ensure that you have installed and powered up the system according to the instructions in Section 3.

2.

Connect the monitor to the ‘monitor 1’ socket on the Remote Unit (see Figure 4).

3.

Enter Command mode (see page 28).

4.

If you want to apply the monitor’s DDC settings to BOTH video channels, continue to step 6.

5.

Select the video channel to which you want to apply the DDC settings (see page 30) by pressing either <1> or <2>.

6.

Press the key combination:

<Left Control> + <D>

7.

The DDC information is read from the monitor and applied to the selected video channel(s) in the Local unit. This may take a few seconds. The Remote console keyboard LEDs flash twice to indicate a successful transfer.

Always reboot Windows after adjusting a DDC parameter.

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

5. Local Unit Operation

5.1 Overview

For more information about serial/audio port operation, see Appendix E: Audio/Serial

Ports, page 47.

Keyboard and Mouse Emulation

Local units have keyboard and mouse emulation. The attached PC operates normally without requiring a keyboard or mouse to be attached to either the Remote or Local units (in the case of a dual access system). You can therefore replace any keyboard or mouse attached to the extender system without disrupting the operation of the computer.

Power

Local units may require an external 5V PSU (PSU1006E):

• For video only applications.

• If the PC cannot provide sufficient power through the keyboard connection.

5.2 Dual Access Systems

ACU3209A and ACU3228A models offer dual access from consoles at both Remote and

Local units. This operates on a first-come, first-served basis. When one console is in use, the system blocks out the other console until there is no keyboard or mouse use at the active console for two seconds. Both monitors show the current activity on the computer irrespective of which console is in use.

Only Reset and Private Mode commands are available at the Local unit. If you want to configure the Extender system (for example, change DDC emulation) or tune the video signal, see page 28; these commands can only be issued from the Remote console.

To enter these commands:

1.

Press and release the initial ‘hot’ key sequence.

<Left Control> + <Left Shift> + <F10>

2.

Press and release the command key.

34

LOCAL UNIT OPERATION

Local Console Commands

After pressing the initial ‘hot’ key sequence ( <Left Control> + <Scroll Lock> + <F10>) on the Local keyboard, you can issue a number of commands by pressing additional keys. These commands allow you to control a Private mode session at the Local console, reset the keyboard and mouse or restore the Local Unit’s factory default settings.

Command Key Sequence

Toggle Local Unit Private Mode <Scroll Lock>

ACU3209A, ACU3228A only

Use this command to begin or end a Private Mode session at the Local console (see page 32).

Toggle Remote Video Blanking State <Left Control> + <Scroll Lock>

ACU3209A, ACU3228A only

Use this command to determine whether the Remote console monitor will be blanked (default setting) or enabled during a Private mode session at the Local console (see page 32).

Reset Local Keyboard and Mouse <F1>

Resets the Local console’s keyboard and mouse. You may need to do this if you have hotplugged a keyboard or mouse and it has not initialized correctly.

Mouse Recovery <F3>

Use this command if you experience erratic movement of the mouse pointer or you have lost mouse movement after hot plugging the Local unit into the CPU. In the case of erratic mouse movement, you may need to enter the command a number of times to re-synchronize the mouse signal. Alternatively, stop moving the mouse for a few seconds and the operating system’s mouse drivers may automatically re-synchronize the signal. If the Local unit has been hot-plugged, this command will issue a request to the OS to initialize the mouse. Use

this command with care.

Exit Command Mode and Save <Esc>

Exit Command Mode and save all settings to EEPROM.

Set Local Unit to Default State <Left Control> + <F9>

Restore Local Unit factory defaults (configuration and DDC).

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

6. Troubleshooting

6.1 Video

The image is not sharp, or is badly smeared.

Have you adjusted the video equalization? Follow the instructions on page 30.

Check the Interconnect cable between the Remote and Local units. Is it of the recommended type (see page 20)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly (see page 30)?

Ensure that all video connections throughout the system are attached securely.

Are you using an LCD panel? You need to adjust its clock and/or phase.

Colors appear to be separated and there are colored borders on text and icons.

Check the Interconnect cable between the Remote and Local units. Is it a recommended ‘low skew’ type (see page 20)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly (see page 46)?

You can check whether skew is a problem in your system by viewing the test card at: http://www.blackbox.com/tech_support/ts_upgrades/ts_ss.html.

I only need video extension – not keyboard or mouse - but I can’t get a picture.

Have you powered the Local unit? The Local unit gets its power from the CPU through the keyboard connection and it will not operate without it. Use an external

5V PSU as described on page 34.

The monitor sometimes goes blank for a second or two.

Check that the interconnect cable is not routed near power lines or other sources of electrical interference. Use shielded STP/FTP cable instead of UTP cable and ensure the shield connection is maintained between the Extender units.

Check system grounding.

If this is a persistent problem, contact Technical Support.

The PC won’t boot into the correct graphics mode.

Check that DDC Emulation is enabled (see page 32). If you are using a nonstandard resolution, transfer the monitor’s DDC information to the Local Unit (see page 33).

36

TROUBLESHOOTING

Jitter is evident on video.

Adjust the clock and/or phase on your flat-panel. Contact Technical Support if this fails to improve the situation.

Are you testing a system using a coiled drum of CATx cable? Try uncoiling the cable. If this solves the video jitter, you should not have a problem after full installation.

The image is not stable and is blanking regularly.

Re-power the Remote unit.

Can the extender be used with RGB video?

Yes.

6.2 Keyboard & Mouse

When I am typing, I get wrong or missing characters on the screen.

Your keyboard may be in the wrong mode. Use the appropriate commands to reset the keyboard and mouse as described in the sections covering Local and Remote operation.

The PC comes up with ‘keyboard error’.

Press <F1> or <ESC>. If the keyboard now operates correctly, you need to adjust the BIOS setup to disable keyboard testing during booting.

The system does not detect a PS/2 mouse.

If connecting the Local unit to a live system, connect the mouse cable to the CPU

before keyboard connection to ensure the mouse is enabled correctly.

Issue the Mouse Recovery command.

Check that the mouse cable is connected properly and securely. Reboot the system.

The mouse pointer moves erratically.

Reset the keyboard and mouse.

Issue the Mouse Recovery command up to three times.

Ensure that you have the latest driver for your mouse.

If you are using the extender with a KVM switch, command the switch to reset the mouse.

Quit and restart the application. Reboot the PC.

37

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

When I ‘hot-plug’ the Local unit, the mouse no longer moves.

When connecting the Local unit to a live system, connect the mouse cable to the

CPU before keyboard connection to ensure the mouse is enabled.

Try issuing the Mouse Recovery command.

Some of the mouse buttons don’t work.

The PS/2 Micro Extender units support standard 2/3-button mice (with or without a wheel). Additional buttons will not operate.

I have an enhanced keyboard with extra keys and indicators. Everything works apart from these additional features.

As standard, the extender only emulates a generic PS/2 keyboard. To support other keyboards (or cascaded KVM switches), special firmware offering a transparent

mode may be required. Please contact Technical Support to discuss your application.

6.3 Audio

The audio is very quiet.

The audio I/O is line-level and requires amplified speakers and connection to devices providing line-level I/O.

The audio is loud but distorted.

Check that the audio input is not greater than line level (4V peak-to-peak). The

KVM extender accepts line-level audio input only.

The microphone output is barely audible.

See Appendix E: Audio/Serial Ports, page 47.

6.4 Serial

My serial device does not function.

The extender supports serial devices at data rates not exceeding 19.2K Baud

(although 38.4K operation might be possible with certain equipment).

Check the type of flow control used by the device and CPU. The extender supports

RTS, CTS, DTR, and DSR. Some systems may require a wiring adapter to transfer

RI and DCD.

Attach the device directly to the serial port on the PC and test whether the problem is a PC or extender problem.

Some serial devices cannot be hot-plugged. Try connecting the device to a powered

Remote unit prior to booting the system.

38

TROUBLESHOOTING

6.5 General Questions

Is it possible to use a cable length longer than 150ft (50m)?

It might be possible to use a cable of up to 300ft (100m) at lower resolutions.

However, we do not recommend this and cannot guarantee the video quality.

Can extenders be daisy chained?

In certain circumstances, it is possible to cascade extenders, though we do not recommend doing so. Careful consideration needs to be given to extender setup, and the electrical environment. If you plan to cascade extenders, please contact

Technical Support.

Which interconnection cable is best?

In electrically ‘quiet’ environments, UTP cable will give the best quality video over long distances because it has less capacitance per unit length. However, STP/FTP is usually better in electrically noisy environments, because it resists interference more strongly (if it is installed correctly!) and limits ground potential differences.

Can the extender system be used between buildings?

No. Ground loops could damage the extender system and attached equipment.

Can multiple Local/Remote units be used by swapping the interconnection cable?

Local units provide full keyboard and mouse emulation, so it is possible to swap or switch the Local-Remote interconnection to create a KVM matrix-switch system.

Sometimes you may need to reset the keyboard and mouse (by entering the appropriate command) after a swap or switch. Please call Technical Support before deploying such a system.

Can the extender be connected into our network?

Absolutely not. Regardless of the cable similarities, the data signals and voltages used by the extender are different from those used by Ethernet and other types of networks. Connecting the extender to a LAN hub, switch, repeater, or other network device, or exposing it to the signal levels present on network data lines may damage the extender and other devices.

APPENDIX C: FLASH UPGRADING

Appendix C: Flash Upgrading

& External Configuration

Each extender unit contains a service port. This can be accessed through the mouse port on a

Remote unit or through the 25-way D-connector on a Local unit. By attaching an upgrade cable between the appropriate port and the serial port on any PC (or laptop) a unit’s firmware may be upgraded.

To operate the configuration port, you need:

• A laptop or PC close to the extender unit running Windows 98 or above. The extender unit only has to be powered.

• An upgrade cable connected between the Extender’s service port and the laptop or PC’s serial port (Part No: ACUFLH-R2).

• A software utility called ‘ConfigXt’.

• The firmware upgrade file.

The application, detailed instructions and firmware upgrades may be downloaded online.

Please consult Technical Support for details on how to do this.

APPENDIX E: AUDIO/SERIAL PORTS

Appendix E: Audio/Serial Ports

Operation & Multi-Port Configuration

This appendix describes audio & serial interface operation for those models that have this feature:

• ACU3222A

• ACU3228A

• ACUMRA02A

These extender products contain daughter boards that allow bi-directional stereo audio and a full-duplex serial data link to be sent across the CATx interconnection cable in addition to

PS/2 keyboard, mouse and video.

Serial Interface - Set Up and Operation

No setting up or user adjustments are required. Please note that on dual access Local units, the serial link is always active.

The Remote unit’s serial port is wired as DTE - the same as that on a PC. To connect a serial printer or other DTE (rather than DCE device) to the Remote unit, you will need a Null-

Modem crossover cable between the Remote unit and the printer. Select Xon/Xoff software flow control on the printer and PC.

A serial touch screen may be plugged directly into the Remote unit.

Serial Interface – Handling Multiple Serial Devices

The extender’s serial interface transmits/receives six signals (3 signals in each direction).

Normally, four of these signals are used for hardware handshaking (in addition to TX & RX).

However, because each handshaking line can support signals up to 19,200 Baud it is possible to configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links.

To do this, you will need to construct a custom breakout cable. Please contact Technical

Support for further information.

47

SERVSWITCH PS/2 MICRO EXTENDER FAMILY

Audio Interface - Set Up and Operation

The audio interface is line-level and is designed to take the output from a sound card (or other line-level) source and be connected to a set of powered speakers at the other end of the link.

Stereo audio may be transmitted either way across the link (simultaneously).

No setup is required unless a microphone is connected to the Remote unit.

Connect the extender as follows:

• Take the line-level output from your sound card (green connector) and connect to ‘Line

In’ on the Local unit.

• Connect ‘Line Out’ on the Remote unit to a set of powered speakers.

Audio Interface – Using a Microphone

A microphone may be plugged into the ‘Line In’ connector on the Remote unit.

There are two ways of setting up a microphone:

• The Local unit’s ‘Line Out’ connection should normally be wired to the microphone input (Pink) on your sound card. The sound card should then be set up to provide additional amplification (+17dB). This is the preferred connection method.

• Alternatively, the Remote unit itself can provide microphone amplification. To set this, open up the Remote unit and locate the jumper labeled ‘MIC’ on the daughter board.

Connect this jumper across the pins. The Local unit’s ‘Line Out’ connection should then be wired to ‘Line In’ (Blue) on your sound card.

If your microphone is already amplified, follow the second method but DO NOT install the amplification jumper in the Remote unit.
