Welcome to the ServSwitch™ Family!

Thank you for purchasing a BLACK BOX® ServSwitch™ Brand CAT5 KVM 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 CAT5 KVM Extender, including how to install, operate, and troubleshoot it. For an introduction to the Extender, see

With some cables, video performance may be improved by using a crossover patch cable at each end, an alternative RJ45 pin-out or an external skew correction device (see Appendix C: Advanced Cabling Issues (Skew), page

45).

INSTALLATION

Setting the Cable Length Jumpers

If your application uses a CATx cable less than 75m in length, you can continue to the next section.

Remote Units incorporate video equalization circuitry, allowing you to compensate for the loss in image quality that occurs when video signals are transmitted along lengthy CATx cables. At the factory, Remote Units are configured to optimize the video signals for

Interconnect cables up to 100m in length.

If you intend to use cables of 100-300m in length:

1. Unfasten and remove the screws on each side of the Remote Unit.

2. Carefully remove the top plate.

3. Locate the three cable length jumpers on the Remote Unit’s main circuit board (see

Figure 2).

If you are at the top end of a cable range, and you are using a high screen resolution (1024x768 or higher), you may achieve better quality video compensation by selecting the next cable length range.

Ensure that all three jumpers are set to the same position. If you are carrying out a test placement prior to final installation, set the jumpers to the positions appropriate to the test cable’s length. When your tests are complete, set the jumpers to the positions appropriate for the CATx cable length used in the full installation.

While you have the Remote Unit’s cover off, you may also want to change some of the other jumper settings or DIP switch options:

REMOTE UNIT CONFIGURATION & OPERATION

4. Remote Unit Configuration &

Operation

Cat5/5e cables are specifically designed for networking applications and not for transmitting analog video. Your CATx KVM extender includes, and requires, advanced technology to enable its use at high screen resolutions. This section describes how to optimize the video signal, configure the Extender system and operate the Remote Unit.

To get the best out of your extender system it is essential that you configure it correctly and tune the video signal. Tuning is necessary because of distortions that occur in a video signal when it is transmitted over lengthy CAT5/5e cables. Generally, you only need to carry out this procedure after installation.

When you have installed your extender system, run an application that requires a high screen resolution. Examine the video image on the remote console’s monitor. You may see some of the following distortion effects:

Smearing Loss of Sharpness

Black smearing at the right edge of large horizontal objects such as title bars.

Blurring and lack of detail, edges appearing too bright and sharp.

Color Separation or Skew Brightness

Displacement of individual colors

(caused by timing differences in RGB signal reception).

Image appears brighter or darker than the original.

The Remote Unit’s Focus control allows you to correct smearing and loss of sharpness effects. The Brightness control adjusts video image brightness.

REMOTE UNIT CONFIGURATION & OPERATION

Skew only tends to be a problem at high screen resolutions with long interconnect cables. We recommend the use of low skew CAT5/5e cable for all applications. Please contact Technical

Support for more information.

Issues (Skew), page 45).

The alternative ServSwitch™ Brand CATx KVM Extender range has been specifically designed for the extension of high screen resolutions

(1600x1200) over long CATx cables (300m). ServSwitch™ Brand CATx

KVM Extenders have fully integrated skew compensation and independent control of low frequency (LF) and high frequency (HF) cable equalization.

Remote Units feature a number of correction tools to simplify video optimization. This procedure is straightforward and only needs to be carried out once.

Please note that cable equalization cannot be exact – the remote image will never be as sharp as the original. The KVM Extender’s equalization system produces good results for short to medium length cables (<150m).

Adjusting Video

Use the following step-by-step procedure to optimize the video image on the remote console:

1. If possible, view the online test card at: ftp://ftp.blackbox.com/connectivity/ServSwitch/

This is an image (see Figure 9) created and used by the manufacturer for video optimization purposes. It is particularly useful for observing skew. If you are unable to view the test card, display some text in a large font on a white background.

You should also open up other application windows to check the clarity of text in tool bars and icons on the desktop.

2. Turn the Brightness and Focus controls on the Remote Unit fully anti-clockwise. The image quality may be poor at this point.

3. Use the Focus control to adjust video equalization. If the video signal is undercompensated, you will notice black smearing on the right-hand edge of large horizontal objects such as title bars. If it is overcompensated, horizontal edges may become bright and too sharp. Rotate the Focus control clockwise until these effects disappear. The compensation is now adjusted correctly for the length of cable.

REMOTE UNIT CONFIGURATION & OPERATION

If you are at the top end of a cable range, for example, 80m (250ft), and you are using a high screen resolution (1024x768 or higher), you may achieve better quality video compensation by selecting the next cable length range using the cable length jumpers (see page 19). Use the

Brightness control to adjust the brightness of the overall picture. After adjusting this control, you may need to re-adjust the Focus control.

4. If you are using a flat panel monitor at the remote console, carry out autoadjustment as described in the monitor’s documentation. Sometimes manual adjustment of clock and/or phase is also required for optimum results and minimization of jitter.

REMOTE UNIT CONFIGURATION & OPERATION

Hot Key Commands

After pressing the initial ‘hot’ key on the remote keyboard, you can issue a number of commands by pressing additional keys. These commands allow you to start a private mode session on the remote console or to reset the keyboard and mouse.

Private Mode

(ACU1028A, ACU1049A, ACUVREM, ACUREMSW only)

<Scroll Lock>

Audio/Serial Local Units that feature dual access allow the remote user to lock out the local console by triggering a ‘Private Mode’ function. This prevents the local console from being used even if a two second inactivity timeout period expires.

During a Private Mode session, the extender system:

•

Flashes the Scroll Lock LED on the remote keyboard.

Illuminates all three LEDs on the local keyboard.

Displays a blank image on the local console’s monitor.

Locks the local console’s keyboard and mouse.

Reset Keyboard and Mouse <Num-Pad Up Arrow>

Reset the remote 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 <Num-Pad Left Arrow>

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.

Switch to other PC

(ACU1049A and ACUREMSW only)

<Num-Pad + >

Toggles KVM switch in Remote Unit so that the remote console controls either the second

PC (connected directly to the Remote Unit) or the extended PC.

Note: On power-up, the Remote Unit will switch to the first active CPU.

LOCAL UNIT OPERATION

5.1 Overview

You need to read this section if you have purchased an extender system kit containing both a

Local and Remote Unit.

For more information about serial/audio port operation, see Appendix D: 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 Requirements

Local Units normally take power from the keyboard connection to the computer. For video only applications, you must apply external power through this port. Use an external 5V PSU with PS/2 connector (Model: PSU1001E-LOCAL).

Contact Technical Support for further information.

LOCAL UNIT OPERATION

5.2 Operation of Dual Access Local Units

Models ACU1028A and ACU1049A offer dual access with a second console at the Local

Unit. 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 a set time: the Inactivity Timeout Period. This is fixed at two seconds. Thereafter, any keyboard or mouse action at the other console switches console activity.

When the PC is booted, the local console is active. When you are activating a console, the first key or mouse press is not passed to the PC.

ACU1028A only: When the local console is in Private Mode, audio transmission to the Remote Unit is stopped but the serial link is maintained

Hot Key Commands

With dual access systems, keyboard hot keys are used to carry out various functions at the local console.

To enter these commands:

1. Press and release the initial ‘hot’ key.

By default, the initial ‘hot’ key is <Right Control>.

2. Press and release the command key.

With these systems, the Scroll Lock operates as normal unless you have pressed the initial hot key.

Changing the Initial Hot Key

The Local Unit’s initial ‘hot’ key may be changed from <Right Control> to <Left Control> using a DIP switch on the Remote Unit’s main circuit board (see Figure 10).

LOCAL UNIT OPERATION

Local Console Commands

After pressing the initial ‘hot’ key on the local keyboard, you can issue a number of commands by pressing additional keys. These commands allow you to start a private mode session on the local console or to reset the keyboard and mouse.

These commands only apply to Local Units having firmware versions ‘S50’ and above.

Private Mode

(ACU1028A and ACU1049A only)

<Scroll Lock>

Audio/Serial Local Units that feature dual access allow the local user to lock out the remote console by triggering a ‘Private Mode’ function. This prevents the remote console from being used even if the two second inactivity timeout period expires.

During a Private Mode session, the extender system:

•

Flashes the Scroll Lock LED on the local keyboard.

Illuminates all three LEDs on the remote keyboard.

Displays a blank image on the remote console’s monitor.

Locks the remote console’s keyboard and mouse.

Stops audio transmission.

Switches to remote CPU (ACU1049A only).

Reset Keyboard and Mouse <Num-Pad Up Arrow>

Reset 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 <Num-Pad Left Arrow>

this command with care.

The ACU1049A Local Unit allows the local console to operate the local

CPU and the remote console to operate the remote CPU at the same time.

TROUBLESHOOTING & FAQ

6. Troubleshooting & FAQ

6.1 Video

The image is not sharp, or is badly smeared.

Have you adjusted the video equalization? Follow the instructions on page 29.

Check the Interconnect cable between the Remote and Local Units. Is it of the recommended type (see page 17)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly?

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 that the compensation jumper setting is correct for the length of your

Interconnect cable (see page 19).

See Appendix C: Advanced Cabling Issues (Skew), page 45.

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 33.

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 ensuring that the shield connection is maintained between the extender units.

Check system grounding. The Remote Unit has an isolated power supply and relies on obtaining a ground reference through the connected monitor. Some monitors on the market have an external PSU which itself may be isolated from power ground.

If this is the case, and you are experiencing monitor blanking, you may need to consider grounding the Remote Unit chassis (to power ground) or replacing the monitor’s power supply with a non-isolated model.

If this is a persistent problem, contact Technical Support.

TROUBLESHOOTING & FAQ

The PC won’t boot into the correct graphics mode

The extender includes DDC emulation for all standard resolutions and there should not normally be any issues.

For non-standard resolutions, you will need to explicitly set the resolution in your operating system configuration ignoring the DDC data read from the Local Unit.

Contact Technical Support if you have problems selecting your required graphics mode.

Can the extender be used with RGB video?

Yes.

6.2 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 D: Audio/Serial Ports, page 47.

6.3 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.

TROUBLESHOOTING & FAQ

6.4 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. Try issuing 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.

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 Extenders 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.

The extender 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.

TROUBLESHOOTING & FAQ

Is it possible to use a cable longer than 300m?

It might be possible to use a cable of up to 500m at lower resolutions. However, we do not recommend this and cannot guarantee that it will work.

Can the extender 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?

The extender will operate with either shielded (STP/FTP) or unshielded (UTP)

CATx cable. However, correctly installed shielded cable is preferred, especially in electrically noisy environments, because it resists interference more strongly, limits ground potential differences, and reduces emissions. To benefit from shielded cable the shield connection must be maintained from end to end through any intervening patch cables, panels and RJ45 connectors.

Please note that shielded cable is advised in order to maintain regulatory EMC compliance.

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: ADVANCED CABLING ISSUES (SKEW)

Appendix C: Advanced Cabling Issues

(Skew)

This section discusses skew and how to minimize its effects.

What is Skew?

Each color in the RGB (Red, Green, Blue) video signal is sent down a separate pair of wires in the Interconnect cable. On many cables, the twist rates differ and this leads to each color arriving at a slightly different time and therefore spreading out on the screen.

Certain CATx cables can show noticeable skew when operating at high video resolutions over longer lengths of cable (see page 28). Skew problems are best avoided by using ‘low skew’ cable. This is CATx cable with closely matched twist rates. Please contact Technical Support for recommendations.

Correcting Skew

If a change in cable is not possible, or if you still observe color separation when using low skew cable, you could try one of the techniques described in this section:

•

Optimizing pairs (to match pairs for RGB video)

•

Patch cables (to minimize visible distortion)

•

Extender with Skew Compensation (to delay fastest signals)

You can check the relative delays in the color signals using the test card, as described on page

29. Skew causes the color bars in the test pattern to be displayed at slightly different horizontal positions on the screen. To fully correct skew, the two color bars furthest to the left require delaying until they align with the color bar on the right (slowest).

Optimizing Pairs

This technique is a general solution for optimizing video transmission along a CATx cable.

The aim is to arrange the color and data signals as shown in the following table:

Pins Pair

7 & 8

1 & 2

4 & 5

3 & 6

Shortest Pair (Fastest)

3 rd

Longest Pair

2 nd

Longest Pair

Longest Pair (Slowest)

Blue Video

Red Video

Green Video

APPENDIX C: ADVANCED CABLING ISSUES (SKEW)

You can measure pair lengths with a LAN cabling tester (TDR) or view pairs by stripping back a small piece of cable and viewing how tightly the pairs are twisted. The most tightly twisted pair is the slowest (longest) and the loosest pair the fastest (shortest). You can also observe relative delays using the test card.

Some cables have a ‘3+1’ construction where three pairs closely match. The fourth pair should be used for data and the other pairs sorted as in the above table. Other cables have a

‘2+2’ construction where there are two sets of dissimilar pairs. Put red and green on one set

(tightest) and blue & data on the other.

A suitable pair-swapping scheme is easily made using custom wired patch cables at each end of the Interconnect cable.

Extender with Skew compensation

In more extreme cases, you should consider using an alternative extender with an in-built

Skew Compensation feature such as the ACU2000 series. This allows you to set independent delay values of up to 42nS on each color signal. Contact Technical Support for details

Patch Cable

To obtain optimal video performance with your existing setup, it is desirable to have the green signal as the reference (slowest). This is because the human eye is extremely sensitive to additional green distortion (introduced by delays).

If your system requires a large delay on the green signal, try using a crossover patch cable at each end of the link (instead of straight patch cables to connect to wall outlets). In many cases, the crossover should transfer the delay requirement to the blue signal rather than green.

The human eye is much less sensitive to blue distortion and so video quality appears to be improved. The main cable should be wired according to EIA-568B as shown on page 17.

Using a crossover cable (at each end) will put the green video on the orange colored pair and the blue video on the green colored pair.

EIA-568A wiring can also be used to the same effect. Contact Technical

Support for details.

APPENDIX D: AUDIO/SERIAL PORTS

Appendix D: Audio/Serial Ports

Operation & Multi-Port Configuration

This appendix describes audio & serial interface operation for:

•

ACU1022A

•

ACU1028A

•

ACUVREM

These extender products contain daughter boards that allow bi-directional stereo audio and a full-duplex serial data link to be sent across the CAT5/5e interconnection cable in addition to

PS/2 keyboard, mouse and video.

When a dual access Local Unit is in a Private Mode session, audio transmissions to the Remote Unit are stopped but the serial link remains active.

Set up and Operation

No setting up or user adjustments are required.

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.

Please note that on dual access Local Units, the serial link is always active.

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.

APPENDIX D: AUDIO/SERIAL PORTS

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.

There is no output on the Local Unit to connect a set of speakers. If you require a set of speakers at the local console, use a 3.5mm stereo socket doubler on the audio input to the extender.

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.
