SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 3. Introduction By using the Local and Remote Units that together make up the ServSwitch™ Brand CAT5 KVM or KVM/Serial/Audio Micro Extender, you can place your VGA monitor, keyboard, and mouse as far as 50 meters (160 ft.) from the PC-compatible CPUs they communicate with. The Single-Access (ACU3001A) model of the Extender is designed to perform KVM extension only.
CHAPTER 3: Introduction 3.1 Compatibility The ServSwitch Brand CAT5 KVM Micro Extender is designed to operate in various environments and with a mix of hardware from different manufacturers. During development, this product was extensively tested with a wide variety of hardware. However, please note that it is impossible for us to guarantee that the Micro Extender will interoperate correctly with every keyboard, mouse, monitor, motherboard variant, and RS-232 device currently on the market.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER • Mouse: Standard PS/2 type, Microsoft® IntelliMouse® compatible, or Logitech™ 3-button PS/2 compatible mouse; the CPU should have standard PS/2 type mouse ports. The KVM/Serial/Audio Micro Extender can handle a serial mouse if it’s attached to the Remote Unit’s serial port, but the other models are not compatible with serial mice and require adapters to support PCs with PC/AT type serial mouse ports—see the Note below.
CHAPTER 3: Introduction 3.2 Key Features The ServSwitch Brand CAT5 KVM Micro Extender has a number of useful features which contribute to the transparent remote operation of your PC. Some of the more important ones are: • Distance up to 50 m (160 ft.) Operate your PC from the next room or all the way down the hall. • Adjustable video equalization Compensates for the loss of image quality caused by the signal passing through more than 25 m (80 ft.) of cable.

CHAPTER 4: Checklist of System Components 4.2 The Cables You’ll Need If you are using the ServSwitch™ Brand CAT5 KVM Micro Extender to get greater distance between a CPU and a VGA monitor, PS/2 keyboard, and PS/2 mouse, your Micro Extender package should have included everything you’ll need except for your Unit-interconnection cable. Read Sections 4.2.1, 4.2.3, and 4.2.5 carefully, then skip ahead to Chapter 5.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 4.2.2 TO CONNECT A SERVSWITCH FAMILY KVM SWITCH TO THE LOCAL UNIT’S CPU PORT You would do this to extend the distance you can run from the KVM switch to a monitor, a keyboard, a mouse, and possibly serial and/or audio devices. (You could also do this to extend the distance you can run between two cascaded switches, but for this to work, each switch must be either a ServSwitch Jr.
CHAPTER 4: Checklist of System Components 4.2.2.B Switches with DB25 Composite User Ports The user ports of some ServSwitch family KVM switches are specially pinned DB25 connectors that function as composite (all-in-one) interfaces.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 4.2.3 TO CONNECT A MONITOR, KEYBOARD, AND MOUSE TO THE REMOTE UNIT OR TO THE USER PORTS ON THE DUAL-ACCESS LOCAL UNIT You’ll be plugging the monitor, keyboard, and mouse directly into the corresponding user ports on the Remote Unit or Dual-Access Local Unit.
CHAPTER 4: Checklist of System Components 4.2.4 TO CONNECT A SERVSWITCH FAMILY KVM SWITCH TO THE REMOTE UNIT OR TO THE USER PORTS ON THE DUAL-ACCESS LOCAL UNIT You would do this to extend the distance you can run from the KVM switch to a CPU. (You could also do this to extend the distance you can run between two cascaded switches, but for this to work, each switch must be one of the ServSwitch family models with regular ServSwitch style DB25 composite interfaces listed in Section 4.2.4.B.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 4.2.4.B Switches with Regular ServSwitch Style DB25 Composite CPU Ports The CPU ports of the regular ServSwitch and several other ServSwitch family KVM switches are specially pinned DB25 connectors that function as composite (all-inone) interfaces. At the time of this writing, some of the other important ServSwitch family models in this category are: • ServSwitch™ • ServSwitch™ Ultra • Matrix ServSwitch™ • ServSwitch™ Affinity • ServSwitch Jr.
CHAPTER 4: Checklist of System Components 4.2.5 TO CONNECT THE LOCAL UNIT TO THE REMOTE UNIT To interconnect the Local and Remote Units of the Micro Extender, you’ll need industry-standard structured cabling (Category 5 UTP or STP, 4-pair) terminated with RJ-45 plugs. This cable is not included with the Extender. You’ll need CAT5 patch cables such as our product code EYN737MS or CAT5 bulk cable such as our EYN840A.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 5. Configuration There’s a two-position DIP switch on the bottom of the Remote Unit of the ServSwitch™ Brand CAT5 KVM and KVM/Serial/Audio Micro Extenders. Position 1 governs the Remote Unit’s video equalization, while position 2 controls how the Remote Unit handles keyboard-command recognition. 5.
CHAPTER 5: Configuration 5.2 Setting DIP-Switch Position 2: Keyboard-Command Recognition The function of DIP-switch position 2 depends on the Micro Extender model: • On the ACU3001A and ACU3009A Remote Units, position 2 controls how the Remote Unit handles [Scroll Lock]. Normally, pressing [Scroll Lock] on the Remote Unit’s attached keyboard causes the Extender to reset itself (see Section 7.3.1) or, in Dual-Access systems, to go into Private Mode (see Section 7.3.4).
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 5.3 Setting the Microphone-Amplification Jumper in the KVM/Serial/Audio Remote Unit (Not Normally Necessary) All sound cards that we have tested so far with the KVM/Serial/Audio Micro Extender (ACU3022A) are able to amplify the incoming signal from a microphone—the card should be set to amplify the signal by +20 dB.
CHAPTER 6: Installation 6. Installation To install your ServSwitch™ Brand CAT5 KVM Micro or KVM/Serial/Audio Micro Extender system, first test-place it (if you want to) as described in Section 6.1, then attach devices as described in Section 6.2, then finish your installation as described in Section 6.3. 6.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER As you attach devices to the Extender, here are some things to keep in mind: • Use caution if you’re attaching KVM switches: Different ServSwitch family KVM switch models use different proprietary signaling between cascaded switches. The only ServSwitch family switch models whose cascade signals the Micro Extenders can carry are those with a regular ServSwitch style DB25 composite interface (see the list in Section 4.2.4.
CHAPTER 6: Installation 6.2.1 SPECIAL CONCERNS ABOUT CONNECTING AUDIO DEVICES TO THE KVM/SERIAL/AUDIO MICRO EXTENDER Before you connect any sound equipment to the KVM/Serial/Audio Micro Extender, here are some things you should keep in mind: The Extender’s audio interface is stereo, bidirectional (sound can be transmitted in both directions across the link at the same time), and line-level (it supports devices that transmit and receive at up to 5 volts peak-to-peak).
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 6.2.2 ATTACHING A CPU TO THE LOCAL UNIT’S CPU PORT Attach the keyboard, video, and mouse connectors of the included three-to-one KVM-extension cable to the matching ports on the CPU, as shown in Figure 6-1. Attach the DB25 male connector of this cable to the Local Unit’s DB25 female composite CPU-port KVM connector.
CHAPTER 6: Installation 6.2.3 ATTACHING A SERVSWITCH FAMILY KVM SWITCH TO THE LOCAL UNIT’S CPU PORT The way you’ll do this will depend on whether the KVM switch’s user ports are multiple connectors (see Section 6.2.3.A) or single composite connectors (see Section 6.2.3.B). (Refer to the listings in Section 4.2.2 for which ServSwitch family models are in which category.) 6.2.3.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 6.2.3.B Attaching a KVM Switch with Single Composite User-Port Connectors If the KVM switch’s user ports are ServSwitch style DB25 connectors, run a ServSwitch to ServSwitch Expansion Cable (product code EHN284) from one of these connectors to the Local Unit’s DB25 female CPU-port KVM connector, as shown in Figure 6-3. Regular ServSwitch (KV3108SA-R4) ServSwitch-toServSwitch Expansion Cable (EHN284) Local Unit Figure 6-3.
CHAPTER 6: Installation NOTES If the switch is a ServSwitch Multi, keep these things in mind as you match the serial and audio cables/strands: – The proper DB9 serial connector to use on its User Cable is the one without a yellow band. – The audio cable from the Local Unit’s “Out” connector should be plugged into the blue-banded audio connector on the User Cable. – The audio cable from the Local Unit’s “In” connector should be plugged into the audio connector without a blue band on the User Cable.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 6.2.4 ATTACHING USER-STATION EQUIPMENT TO THE USER PORT ON A REMOTE UNIT OR DUAL-ACCESS LOCAL UNIT Plug the user station’s monitor, keyboard, mouse, any touchscreen or other serial device, and any audio devices directly into the matching user-port connectors on the Remote Unit or Dual-Access Local Unit. (Serial and audio devices plug into KVM/Serial/Audio model only) Remote Unit Figure 6-5. Attaching user equipment to the user port on an Extender Unit.
CHAPTER 6: Installation 6.2.5 ATTACHING A SERVSWITCH FAMILY KVM SWITCH TO THE USER PORT ON A REMOTE UNIT OR DUAL-ACCESS LOCAL UNIT The way you’ll do this will depend on whether the KVM switch’s CPU ports are multiple connectors (see Section 6.2.5.A) or single composite connectors (see Section 6.2.5.B). (Refer to the listings in Section 4.2.4 for which switch models are in which category.) 6.2.5.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 6.2.5.B Attaching a Switch with Single Composite CPU-Port Connectors Run a CPU Cable designed for the KVM switch—refer to Sections 4.2.4.B and 4.2.4.C for product codes—from one of the switch’s CPU-port connectors to the user-port connectors of the Remote Unit or Dual-Access Local Unit, as shown in Figure 6-7 on the next page. (For the regular ServSwitch and the other switches listed in Section 4.2.4.

Attaching a KVM switch with single composite CPU-port connectors (regular ServSwitch shown at top, ServSwitch Multi shown at bottom) to the user port on an Extender Unit.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 6.3 Finishing Your Installation To finish installing your Micro Extender system after attaching devices to it as described in Section 6.2, take these steps: 1. Attach the output cord of the Remote Unit’s power supply to the Unit’s power jack. Then plug the IEC 320 end of the power supply’s input cord into the IEC 320 inlet on the power supply’s transformer. Finally, plug the other end of the input cord into a utility (mains) power outlet.
CHAPTER 6: Installation 5. If the Local Unit’s LED shows that the link between the Units appears to be working, make sure that the remote keyboard functions and that you’re getting video at the remote site. (Be aware that in Dual-Access systems, remote monitors, keyboards, and mice might take up to several seconds to be properly initialized; see Section 7.3.3. Note also that the video quality might be poor at this point if your interconnect cable is longer than 25 m [80 ft.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 7. Operation 7.1 Keyboard and Mouse Emulation The ServSwitch™ Brand CAT5 KVM and KVM/Serial/Audio Micro Extenders use a microprocessor to emulate the presence of a directly connected keyboard and mouse for the attached PC. This means that you don’t have to connect a keyboard or mouse to the PC in order for it to boot; in fact, the PC will boot with only the Local Unit connected.
CHAPTER 7: Operation 7.3 Keyboard Commands and Related Functions This section describes Micro Extender functions that can be controlled with commands that users can type in at the user-station keyboards, as well as some related functions.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER Note that the Extender will automatically reinitialize the keyboard and mouse whenever you attach them. If a reset doesn’t help your remote keyboard or mouse, try cycling power to the Remote Unit. 7.3.2 CORRECTING THE PS/2 MOUSE IF IT GETS OUT OF SYNC On rare occasions, you might notice that, instead of behaving normally, your mouse pointer is moving and jumping erratically all over the screen (and possibly selecting things at random).
CHAPTER 7: Operation three times in order to get a PC with a 4-byte mouse back on track. Note that, unless your mouse driver is an auto-correcting type, sending this command while the mouse is in sync will throw it out of sync.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 7.3.4 PRIVATE MODE (ACU3009A DUAL-ACCESS SYSTEMS ONLY) For applications in which a Dual-Access Micro Extender system’s remote user station is not in a secure location, or must be temporarily kept from accessing the local PC, users at the local station can trigger the Extender’s “Private Mode,” which prevents the remote station from taking control of the local PC even if the inactivity timeout (see Section 7.3.3) expires.
CHAPTER 8: Troubleshooting 8. Troubleshooting 8.1 Common Problems This section discusses difficulties that people sometimes have with the ServSwitch™ Brand CAT5 KVM and KVM/Serial/Audio Micro Extenders, and suggests possible remedies. If the recommended actions don’t help, or if you don’t see your problem here, or if your problem keeps recurring, call Black Box Technical Support as directed in Section 8.3. 8.1.1 KEYBOARD The PC boots correctly with no error messages but the keyboard does not work at all.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER Connecting a keyboard to the Remote Unit has an adverse effect on the remote video. Try using a newer keyboard. (Some older keyboards require too high a current for the Remote Unit to properly drive the video signal.) I’m not using a keyboard, but the Extender doesn’t work at all. See Section 8.1.7. 8.1.2 MOUSE There is a mouse cursor/pointer on the screen, but the mouse does not work. 1. Reset the keyboard and mouse as described in Section 7.3.1. 2.
CHAPTER 8: Troubleshooting The mouse is behaving erratically. 1. Reset the keyboard and mouse as described in Section 7.3.1. 2. Issue the Null Mouse Command up to three times (see Section 7.3.2). 3. If your PC is running Windows 95/98/2000, Windows Me, Windows NT, or Windows XP, regardless of what type of mouse you have, install the latest Microsoft driver for a standard mouse or (even if you have a standard mouse) the IntelliMouse.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 8.1.4 SERIAL DEVICE (ACU3022A KVM/SERIAL/AUDIO SYSTEMS ONLY) The CPU doesn’t detect the serial device I’m trying to use with it. 1. Make sure that the data rates of the device and the CPU’s serial port both match, and that the data rate doesn’t exceed 19,200 bps. 2. Make sure that the device and your PC’s driver or serial-communication program are using the same type of flow control. The CPU doesn’t seem to receive anything from its serial device or vice versa. 1.
CHAPTER 8: Troubleshooting 8.1.5 AUDIO DEVICES (ACU3022A KVM/SERIAL/AUDIO SYSTEMS ONLY) Sound doesn’t seem to get through from the local site to the remote site or vice versa. 1. Check the audio cables, including those attached to your speakers. Are they intact along their length and securely connected at both ends? Are all cables running correctly from “audio out” to “audio in”? 2. Is your sound card actually outputting anything? Check this by temporarily attaching some speakers directly to the card.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER Each character has separated into overlapping sets of red, green, and blue pixels; the effect is like trying to watch a 3-D movie without 3-D glasses. 1. Check the interconnect cable between the Micro Extender’s Local and Remote Units.
CHAPTER 8: Troubleshooting I get black & white instead of color video. Your CPU probably needs to see monitor ID in order to boot into the correct video mode. Please contact Black Box Technical Support. Microsoft Windows 3.x, 95, 98, or 2000, Windows Me, Windows NT, or Windows XP will only boot into a low-resolution graphics mode. 1.
SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER 8.2 General Questions About the Micro Extender Is it possible to use an interconnection cable longer than 50 meters (160 feet)? The standard-from-the-factory Micro Extender has been designed to produce acceptable results with SVGA resolutions at the maximum cable length of 50 m (160 ft.). You can try running cable farther, but not very far beyond 50 m the video quality begins to degrade rapidly.
CHAPTER 8: Troubleshooting When using UTP, what’s the best way to make sure that the system does not suffer from any interference? The Micro Extender is designed to withstand high levels of interference while driving signals over UTP.
