THE SERVSWITCH™ FAMILY

Welcome to the ServSwitch™ Family!

Thank you for purchasing a BLACK BOX® ServSwitch™ Brand CAT5 KVM 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 CAT5 KVM Extender Local Hub, including how to install, operate, and troubleshoot it. For an introduction to the Extender, see Chapter 2. The Extender product codes covered in this manual are:

OVERVIEW

1.6 How to Use This Guide

This guide describes the installation and configuration of the ServSwitch™ Brand CAT5 KVM Extender Local Hub range. Although the connection and operation of these systems is relatively straightforward, you should consider the following before getting started:

Connection & Compatibility

You will require cables to connect your CPUs to the Extender Lo cal Hub.

Order Code Description

EHN230D-xx CPU KVM Combination Cable (DDC Compatible) BC00200 / BC0023x Serial Cable 9-way D (Male-Female) EJ110-xx 3.5mm Audio Cable (Male-Male)

xx = length. Various lengths are available. Contact technical support for details. Ensure that the Remote Units you intend to use are compatible with your Extender Local Hub

(see Extender Compatibility, page 15). For information about connection and installation, see Installation, page 17.

Interconnection Cable

You will need CATx cable, terminated with RJ45 plugs, to connect the Local Hub to your Remote Units (see Interconnection Cable Requirements, page 18).

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. Please refer to the Remote Unit Configuration & Operation section in the manual supplied with your Remote Unit.

INSTALLATION

2. 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 Local Hub system more conveniently.

2.1 Package Contents

You should receive the following items in your extender package. If anything is missing, please refer to Appendix C: Calling Black Box, page 43.

• KVM Extender Local Hub unit.

• 5V DC PSU and power cable.

• Quick Start Guide.

INSTALLATION

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

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. The following table illustrates which RJ45 connector pins the extenders use for various signals. It also details the standard EIA-568B wiring scheme that is recommended for most installations.

OPERATION

3. Operation

3.1 Overview

The operation and configuration of dual access Standard, Serial and Serial/Audio enabled systems is slightly different. Please read the appropriate section for your system.

Dual Access, with consoles at both the Remote Unit and Local Hub port, operates on a firstcome, 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. Thereafter, any keyboard (and, optionally, mouse) action at the other console switches activity.

Local Hubs offering dual access allow the user to lock out the remote console by triggering a ‘Private Mode’ function. This prevents the remote console from being used even if the inactivity timeout period expires.

For more information about serial/audio port operation, Appendix B: Audio/Serial Ports, page 38.

Keyboard and Mouse Emulation

Each port on a Local Hub has keyboard and mouse emulation. The attached PC operates normally without requiring a keyboard or mouse to be attached to either the Remote Unit or Local Hub (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.

OPERATION

3.2 Operation of Dual Access Standard & Serial Local Hubs

ACU1006DRA and ACU1006DSRA only

Scroll Lock Function

Standard and Serial Remote Units redefine the function of the Scroll Lock key for use within the Extender system.

You may need normal Scroll Lock activity for a specific application. In this case, you can restore the Scroll Lock key to its usual function. In doing so, you will disable Private Mode operation on a dual access system. In addition, if you need to reset/recover a console’s keyboard and mouse, you may need to reboot the Remote Unit or the CPU.

Please refer to the manual supplied with your Remote Unit for more details about Scroll Lock key functions and configuration.

Console Switching

With Standard and Serial Extender systems, you can set the Inactivity Timeout Period to 2 seconds (the default) or 15 seconds. You can also choose the method of switching between consoles:

• Any detected keyboard action (the default), or

• Any keyboard or mouse action.

Please refer to the manual supplied with your Remote Unit.

When the PC is booted, the local console is active. When you are activating a console, the first key or mouse button action is not

passed to the PC. ACU1006DSRA only: Serial communication across the Extender system

continues even when the local console is active or in a Private Mode session (see below).

OPERATION

Local Console Commands

On a dual access system, you can issue the following commands at the local console:

Command Key Sequence

Activate Console

Gain control of CPU from remote console. Only operates if inactivity timeout period has expired.

Start/End Private Mode

Start/End ‘Private Mode’ at local console. Private Mode prevents the remote console from being used even if the inactivity timeout period expires.

During a Private Mode session, the extender system:

• Lights the Scroll Lock LED on the local keyboard.

• Lights the Scroll Lock LED on the remote keyboard.

• Locks the remote console’s keyboard and mouse.

• Displays a blank image on the remote console’s monitor. With ACUREM and

ACUSREM Remote Units, you can disable this feature by setting switch 1 on the SW1 DIP switch block on the Remote Unit’s main circuit board to ON. In this case, the remote monitor will continue to show PC activity during a Private mode session.

• Switches remote CPU (ACUREMSW only).

To end a Private Mode session, press the Scroll Lock key on the local console a second time. Remember that each press of the local console’s Scroll Lock key also resets the keyboard and mouse.

Reset Local Keyboard and Mouse

Reset the local console’s keyboard and mouse.

Any key and (optionally) mouse action

press key twice to avoid starting/stopping Private Mode session

Mouse Recovery

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.

Hold down Left and Right Mouse

buttons then press and release <Scroll Lock>

OPERATION

3.3 Operation of Dual Access Audio/Serial Local Hubs

ACU1006DVRA only

The ‘Hot’ Key

With these systems, keyboard ‘hot’ keys are used to carry out various functions. To enter these commands:

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

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

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

key.

You can change the Hot Key to <Left Control>. Please refer to the manual supplied with your Remote Unit for more details about Hot Key configuration.

Console Switching

With Audio/Serial models, the Inactivity Timeout Period 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. When the local console is in Private Mode, all audio/serial transmission is stopped.

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 ACU1006DVRA Local Hubs having firmware versions ‘S50’ and above.

Command Key Sequence

Private Mode <Scroll Lock>

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 loca l k e yboard.

• Illum inates 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.

Reset Local 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.

4.1 Video

The image is not sharp, or is badly smeared.

Check the Interconnect cable between the Remote Unit and Local Hub. Is it of the recommended type (see page 16)? 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. Refer to the manual supplied with your Remote Unit.

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

Check the Interconnect cable between the Remote Unit and Local Hub. 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?

Are you using low skew cable? You may need to use a skew reduction technique. Refer to the manual supplied with

your Remote Unit.

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

Have you powered the Local Hub? Each Local Hub port 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 23.

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. If your remote monitor has an external PSU you may need to consider grounding the Remote Unit chassis (to power ground).

If this is a persistent problem, contact Technical Support.

TROUBLESHOOTING

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. However, you must be using DDC capable CPU cables on each hub port.

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.

The image is not stable and is blanking regularly.

Re-power the Remote Unit.

Can the extender be used with RGB video?

Yes.

4.2 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). KVM Extenders accepts line-level audio input only.

The microphone output is barely audible.

See Appendix B: Audio/Serial Ports, page 38.

4.3 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

4.4 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 manual supplied with your Remote Unit.

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 a Local Hub port 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 as described in the previous sections. Issue the Mouse Recovery command up to three times. Ensure that you have the latest driver for your mouse. If you are using the Hub port 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 Hub port, the mouse no longer moves.

When connecting a Hub port 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

4.5 General Questions

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 Hubs 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 B: Audio/Serial Ports Operation and Multi-Port Configuration

This appendix describes audio & serial interface operation for:

• ACU1006SRA and ACU1006DSRA

• ACU1006VRA and ACU1006DVRA

Please note that on dual access Local Hubs, the serial link remains active during a Private Mode session but audio transmissions are stopped.

Serial Interface Setup and Operation

Serial only systems ACU1006SRA and ACU1006DSRA

Baud Rate

With serial-only systems, you can set the baud rate for a serial extension to 9600bps or 19200bps at the Remote Unit. Refer to the manual supplied with your Remote Unit for more information.

You can override this setting and fix the baud rate at 1200bps using a jumper on the serial daughterboard in the Local Hub. You may want to use this baud rate to extend a mouse device such as an industrial trackball.

In most cases, we recommend that you use PS/2 mouse devices with your extender system. If you have a PC that does not have a PS/2 mouse port:

• Plug a PS/2 mouse into the Remote Unit

• Use an Mdapt (PS/2) Serial Mouse Converter to connect the PC to your Local Unit.

The drivers supplied with certain Wacom Graphics Tablets dynamically alter the baud rate and cannot be used with an Extender Local Hub. There is a version of the driver available with a fixed baud rate. Please contact Technical Support for more information.

To change the baud rate to 1200bps:

2. Remove the Local Hub’s top cover by unfastening the five retaining screws.

3. Lift of the top cover. There are six serial daughter boards for each port in the Local Hub.

Locate the Baud jumper posts on the appropriate serial daughter board (see Figure 10).

The circuit board has several jumper blocks in addition to those shown in Figure 10. Do not adjust any of these settings, as you will cause the extender system to operate incorrectly.

APPENDIX B: AUDIO/SERIAL PORTS

4. Place the jumper across the posts as shown in Figure 11.

5. Set the hardware flow control jumpers to RTS/CTS Flow Control Across CATx Link as

shown in Figure 12. This mode will support most, but not all, serial mouse and trackball devices.

You must also configure the Remote Unit to use this protocol. Refer to the manual supplied with your Remote Unit.

APPENDIX B: AUDIO/SERIAL PORTS

Hardware Flow Control

The serial daughterboards in both Local Hub and Remote Units have a series of jumpers that allow the selection of alternative hardware flow control schemes across the CATx link (see Figure 10). Most applications will not require hardware flow control across the link, and therefore the flow control jumpers are set to loopback by default and should not need adjustment.

The following diagrams show how the jumpers may be set for various flow control schemes. Please contact Technical Support if you are unsure about serial port handshaking methods.

Audio/Serial Interface Setup and Operation

ACU1006VRA and ACU1006DVRA only

Serial Port Configuration

No setting up or user adjustments are required. In the Audio/Serial extender family, the 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 Hubs, 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 B: AUDIO/SERIAL PORTS

Audio Port Configuration

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 Hub 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 Hub’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 Hub’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.
