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 Micro Extender, including how to install, operate, and troubleshoot it. For an introduction to the Extender, see Chapter 2.

Although the connection and operation of these systems 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 serial equipment connect directly to the Remote Unit. If you have purchased a Remote Unit or Hub, ensure that it is compatible with your Local Unit or hub (see Extender Compatibility, page 16). For information about connection and installation, see Installation, page 18. Interconnection Cable You will need CATx cable, terminated with RJ45 plugs, to connect the Local and Remote Units (see Interconnection Cable Requirements, page 19). 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 Operation, page 29. 17 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 Micro 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 C: Calling Black Box, page 46. • Micro Extender Remote Unit (or Hub). • 9V DC universal power supply for Remote Unit.

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. Cable Pinning/Pairing 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. Looking into the RJ45 socket on a Remote Unit, Pin 1 is on the right and Pin 8 on the left. Pin* Color (EIA-568B) Signal 1 2 White/Orange Orange/White Blue Video 3 6 White/Green Green/White Green Video 4 5 Blue/White White/Blue Red Video 7 8 White/Brown Brown/White Data * Looking into the RJ45 socket on a Remote Unit, Pin 1 is on the right and Pin 8 on the left. EIA-568A wiring can also be used. Contact Technical Support for details. Technical Note: Although skew (color separation) can be an issue on some CATx cables, it would not normally be observed on cables <50m. Even so, we still recommend the use of low skew cables with Micro Extenders. 19 INSTALLATION 3.3 Remote Unit Installation Setting the Cable Length Jumpers If your application uses a CATx cable less than 80 ft (25m) in length, or you have an ACU1007A, 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 CATx cables. At the factory, Remote Units are configured to optimize the video signals for Interconnect cables up to 80 ft (25m) in length. If you intend to use cables of 80-150 ft (25-50m) in length: 1. Locate the DIP switches on the underside of the Remote Unit. On a 6-port Micro Extender hub, there are six pairs of DIP switches, also located on the underside, in line with each port. 2. Set DIP Switch 1 as follows: Interconnect Cable Length DIP Switch 1 Position 0 - 80 ft (0 - 25m) OFF (default) 80 - 150 ft (25 - 50m) ON If you are carrying out a test placement prior to final installation, set the DIP switch to the position appropriate to the test cable’s length. When your tests are complete, set the DIP switch to the position appropriate for the CATx cable length used in the full installation. For information about DIP switch 2, see Remote Unit Operation, page 29. Attaching Rack Mount Brackets ACU1006MRA and ACU1006MRVA only You can mount 6-port Micro Extender Remote Hubs in a 19” rack using the supplied brackets. To attach the brackets: 1. Remove the two screws on each side of the Remote Hub case. 2. 3. 4. 5. Match up the holes on a bracket to the vacant screw holes on the Remote Hub case. Fasten the bracket to the Remote Hub using the original screws. Repeat the procedure with the other bracket. Fit the assembly into your 19” equipment rack and fasten using appropriate screws, cage nuts or bolts (not supplied). 20 INSTALLATION 3.4 Connecting the Remote Unit To install a Remote Unit: 1.

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. Activate Console ACU3009A only Any key or mouse action Gain control of CPU from local console. Only operates if local console has been inactive for at least 2s. 29 REMOTE UNIT OPERATION You can restore normal Scroll Lock activity by setting switch 2 on the DIP switch block to ON. If you do this on a Dual Access system (ACU3009A, for example): • Private Mode operation is disabled. • To reset the keyboard and mouse, you will need to re-power the Remote Unit or hot-plug the keyboard and mouse on the Local Unit. 4.2 Operating Audio/Serial Remote Units Micro Extender kits: ACU3022A Micro Extender Remote Unit: ACUWREM Micro Extender 6-port Remote Hub: ACU1006MRVA With these systems, keyboard hot keys are used to carry out keyboard and mouse reset functions. 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. Changing the Initial Hot Key The initial ‘hot’ key for both Remote and Local Units may be changed from <Right Control> to <Left Control> by moving switch 2 on the Remote Unit’s DIP switch block to the ON position. 30 REMOTE UNIT 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 reset the keyboard and/or mouse. Command Key Sequence 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 plugged a keyboard or mouse into a powered Remote Unit 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. Dual Access Commands The Micro Extender range does not include a Dual Access Audio/Serial Local Unit. However, if you use an Audio/Serial Micro Extender Remote Unit with a compatible Dual Access Audio/Serial Local Unit/Hub (for example, ACU1006DVRA), the following commands are available at the remote console: Command Key Sequence Activate Console Any key or mouse action Gain control of CPU from local console. Only operates if local console has been inactive for at least 2s. Start/End Private Session at Remote Unit <Scroll Lock> Start/End ‘Private Mode’ at remote console. This prevents the local console from being used even if the inactivity timeout period expires. During a Private Mode session, the extender system: • Slowly flashes the Scroll Lock LED on the remote keyboard. • Lights all three LEDs on the local keyboard. • Locks the local console’s keyboard and mouse. • Displays a blank image on the local console’s monitor. To end the Private Mode session, press the Scroll Lock key on the remote console a second time. 31 LOCAL UNIT OPERATION 5. 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, Appendix B: Audio/Serial Ports, page 44. 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. 32 LOCAL UNIT OPERATION 5.2 Operation of Dual Access Local Units Micro Extender kit: ACU3009A only Dual Access 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 2 seconds. Thereafter, any keyboard or mouse action at the other console switches console activity. Scroll Lock Function The Remote Unit supplied with the ACU3009A Micro Extender kit redefines the function of the Scroll Lock key (on both the local and remote console keyboards) for system use (see page 29). You can restore normal Scroll Lock activity by setting switch 2 on the Remote Unit’s DIP switch block to ON (see page 29). In Dual Access systems, this will disable Private Mode operation. In addition, if you need to reset/recover a console’s keyboard and mouse, you may need to reboot the system. 33 LOCAL UNIT OPERATION Command Summary On a dual access system, you can issue the following commands at the local console: Command Key Sequence Activate Console Any key or mouse action Gain control of CPU from remote console. Only operates if remote console has been inactive for at least 2s. Start/End Private Mode <Scroll Lock> Start/End ‘Private Mode’ at local console. This 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. 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 Keyboard and Mouse press key twice to avoid starting/stopping Private Mode session <Scroll Lock> Reset the remote console’s keyboard and mouse. You may need to do this if you have plugged a keyboard or mouse into a powered Remote Unit and it has not initialized correctly. Mouse Recovery (press keys simultaneously) Hold down Left and Right Mouse buttons then press and release <Scroll Lock> 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. 34 TROUBLESHOOTING & FAQ 6. Troubleshooting & FAQ 6.1 Video The image is not sharp, or is badly smeared. Check that the cable length DIP switch is correct for the length of your Interconnect cable (see page 20). 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 the Interconnect cable between the Remote and Local Units. Is it of the recommended type (see page 19)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly? Are you using low skew cable (see page 19)? 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 32. 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. 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. 35 TROUBLESHOOTING & FAQ 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 CAT5 cable? Try uncoiling the cable. If this solves the video jitter, you should not have a problem after full installation. 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). Micro Extenders accepts line-level audio input only. The microphone output is barely audible. See Appendix B: Audio/Serial Ports, page 44. 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. 36 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 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 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 (see page 34). 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. 37 TROUBLESHOOTING & FAQ 6.5 General Questions Is it possible to use a cable longer than 50m? It might be possible to use a cable of up to 100m at lower resolutions. However, we do not recommend this and cannot guarantee that it will work. The ACU1007A will work with cables up to 300m in length. Can the micro extender be daisy chained? No, we do not recommend doing this. Which interconnection cable is best? The extender will operate with either shielded (STP/FTP) or unshielded (UTP) CAT5/5e 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. 38 APPENDIX A: EXAMPLE APPLICATIONS Appendix A: Example Applications This section illustrates four specific applications using ServSwitch™ Brand CAT5 KVM Micro Extender units: • Simple system using ACU1006VRA Hub and ACUWREM Remote Units to extend audio, serial and KVM for up to six PCs (Figure 9). • Six remote serial touch screens with local access through a KVM switch (Figure 10). • Integration of two ACU3009A kits with KVM matrix (Figure 11). • ACU1006MRA 6-port Micro Remote Hub used with ACU1006RA local rack for ‘three desk’, dual video extension (Figure 12). For more information about these, or any other complex applications, please discuss suitable extension architecture with Technical Support. 39 APPENDIX A: EXAMPLE APPLICATIONS ACU1006VRA Extender Hub Takes primary video, keyboard, mouse, audio and serial signals from each CPU (only two shown). ACUWREM Remote Units connect to KVM console, audio and serial devices.

Figure 12 Dual Head extension using ACU1006MRA Micro Extender Remote Hub 43 APPENDIX B: AUDIO/SERIAL PORTS Appendix B: Audio/Serial Ports Operation and Multi-Port Configuration This appendix describes audio & serial interface operation for the following CATx KVM Micro Extenders: • ACU3022A • ACUWREM • ACU1006MRVA 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 Setup and Operation 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 NullModem 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. 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. 44 APPENDIX B: 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. 45 APPENDIX C: CALLING BLACK BOX Appendix C: Calling Black Box If you determine that your ServSwitch™ Brand CAT5 KVM Micro Extender is malfunctioning, do not attempt to alter or repair it.
