SERVSWITCH 2.6 PS/2 MICRO EXTENDER FAMILY How to Use This Guide This guide describes the installation and configuration of the ServSwitch Brand PS/2 Micro Extender Series. Although the connection and operation of the system is relatively straightforward, you should consider the following before getting started: Connection & Compatibility If you have purchased an Extender Kit, this will contain all the cables required to connect the Local unit to your PC or KVM switch.
INSTALLATION 3. Installation For first-time users, we recommend that you carry out a test placement, confined to a single room, before commencing full installation. This will allow you to identify and solve any cabling problems, and experiment with the KVM extender system more conveniently. 3.1 Package Contents You should receive the following items in your extender package. If anything is missing, please refer to Appendix F to obtain Technical Support. • Extender Remote unit.
SERVSWITCH 3.2 PS/2 MICRO EXTENDER FAMILY Interconnection Cable Requirements To connect the Local and Remote units you will need CATx (any category 5, 5e, 6 or higher) cable terminated with RJ45 plugs. Interconnect cables must be solid-core type. Stranded patch cable will give poor results over longer distances. The pairing of the cable and pinning of its connectors should normally be in accordance with EIA-568B (see Appendix D: Cable Pinning, page 46). One CATx cable is required for each video channel.
INSTALLATION 3.3 Remote Unit Installation To install a Remote unit: 1. Switch off all devices. 2. Connect your keyboard, monitor(s) and mouse to the Remote unit as shown in Figure 2. These ports may also be attached to the CPU side of a KVM switch in order to have a Remote CPU. However, if you are attempting to use the extender between cascaded KVM switches this may not work. Please contact Technical Support to discuss your application. 3. If appropriate, connect audio equipment and serial devices.

SERVSWITCH 4. PS/2 MICRO EXTENDER FAMILY Remote Unit Configuration & Operation This section describes how to optimize the video signal, configure the Extender system and operate the Remote unit. For details about flash upgrading and external configuration see Appendix C: Remote Unit: Flash Upgrading & External Configuration, page 45. For more information about serial/audio port operation, see Appendix E: Audio/Serial Ports, page 47. 4.
REMOTE UNIT CONFIGURATION & OPERATION Status LEDs in Command Mode In Command Mode, the Remote unit: • Illuminates the yellow Interconnect 1 LED continuously (see Figure 5). Note. The Yellow LED on Interconnect 2 is not lit. • Flashes the status LEDs (Num Lock, Caps Lock, Scroll Lock) on the connected keyboard to indicate the selected video channel (to which adjustments will be applied).
SERVSWITCH 4.2 PS/2 MICRO EXTENDER FAMILY Adjusting Video PS/2 Micro Extender Remote units incorporate video equalization circuitry, allowing you to compensate for the loss in image quality that occurs when video signals are transmitted along CATx cables. At the factory, Remote units are configured to optimize the video signals for Interconnect cables up to 75ft (25m) in length. If you intend to use cables of 75–150ft (25-50m) in length: 1.
REMOTE UNIT CONFIGURATION & OPERATION 4.3 Other Remote Configuration & Operation Options The ServSwitch Brand PS/2 KVM Micro Extender Series has additional commands to reset the keyboard and mouse, to restore the factory default configuration, change DDC settings, and to initiate and control a Private mode session (Dual Access models only). Command Key Sequence Reset Mouse and Keyboard Resets the Remote console’s keyboard and mouse and then automatically exits Command Mode.
SERVSWITCH PS/2 MICRO EXTENDER FAMILY Private Mode On dual access systems, a user at one console can lock out the other console by triggering a ‘Private Mode’ function. This prevents the other console from being used even if the twosecond inactivity timeout period expires. To indicate that the Private Mode session is active, the extender system: • Slowly flashes the Scroll Lock LED on the user’s keyboard. • Illuminates all three LEDs on the other console’s keyboard.
REMOTE UNIT CONFIGURATION & OPERATION Transferring DDC Information To support non-standard screen settings or other features, it is possible to read and store DDC information into the Local Unit directly from the monitors connected to the Remote Unit. You only need to carry out this procedure once; the Extender Units store the DDC information in non-volatile memory and restore it at power-up. 1. Ensure that you have installed and powered up the system according to the instructions in Section 3. 2.
SERVSWITCH PS/2 MICRO EXTENDER FAMILY 5. Local Unit Operation 5.1 Overview For more information about serial/audio port operation, see Appendix E: Audio/Serial Ports, page 47. Keyboard and Mouse Emulation Local units have keyboard and mouse emulation. The attached PC operates normally without requiring a keyboard or mouse to be attached to either the Remote or Local units (in the case of a dual access system).
LOCAL UNIT OPERATION Local Console Commands After pressing the initial ‘hot’ key sequence ( + + ) on the Local keyboard, you can issue a number of commands by pressing additional keys. These commands allow you to control a Private mode session at the Local console, reset the keyboard and mouse or restore the Local Unit’s factory default settings.
SERVSWITCH PS/2 MICRO EXTENDER FAMILY 6. Troubleshooting 6.1 Video The image is not sharp, or is badly smeared. Have you adjusted the video equalization? Follow the instructions on page 30. Check the Interconnect cable between the Remote and Local units. Is it of the recommended type (see page 20)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly (see page 30)? Ensure that all video connections throughout the system are attached securely.
TROUBLESHOOTING Jitter is evident on video. Adjust the clock and/or phase on your flat-panel. Contact Technical Support if this fails to improve the situation. Are you testing a system using a coiled drum of CATx cable? Try uncoiling the cable. If this solves the video jitter, you should not have a problem after full installation. The image is not stable and is blanking regularly. Re-power the Remote unit. Can the extender be used with RGB video? Yes. 6.
SERVSWITCH PS/2 MICRO EXTENDER FAMILY When I ‘hot-plug’ the Local unit, the mouse no longer moves. When connecting the Local unit to a live system, connect the mouse cable to the CPU before keyboard connection to ensure the mouse is enabled. Try issuing the Mouse Recovery command. Some of the mouse buttons don’t work. The PS/2 Micro Extender units support standard 2/3-button mice (with or without a wheel). Additional buttons will not operate. I have an enhanced keyboard with extra keys and indicators.
TROUBLESHOOTING 6.5 General Questions Is it possible to use a cable length longer than 150ft (50m)? It might be possible to use a cable of up to 300ft (100m) at lower resolutions. However, we do not recommend this and cannot guarantee the video quality. Can extenders be daisy chained? In certain circumstances, it is possible to cascade extenders, though we do not recommend doing so. Careful consideration needs to be given to extender setup, and the electrical environment.
