Remote Unit Configuration & Operation 4. Remote Unit Configuration & Operation Cat5/5e/6 cables are specifically designed for networking applications and not for transmitting analog video. Your SDMX PS/2 Mini 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.
22 SDMX PS/2 Mini Extender Range 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).
Remote Unit Configuration & Operation Adjusting Video PS/2 Mini 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 25m in length. If you intend to use cables of 25-50m in length: 1.
24 SDMX PS/2 Mini Extender Range Other Remote Configuration & Operation Options The SDMX PS/2 Mini 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.
Remote Unit Configuration & Operation 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 two-second 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.
26 SDMX PS/2 Mini Extender Range 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.
Local Unit Operation 5. Local Unit Operation Overview For more information about serial/audio port operation, see Appendix E: Audio/Serial Ports: Operation & Multi-Port Configuration, page 40. 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).
28 SDMX PS/2 Mini Extender Range 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 on the local console, reset the keyboard and mouse or restore the Local Unit’s factory default settings.
Troubleshooting 6. Troubleshooting Video The image is not sharp, or is badly smeared. Have you adjusted the video equalization? Follow the instructions on page 23. Check the Interconnect cable between the Remote and Local Units. Is it of the recommended type (see page 13)? Is it intact along its entire length and securely connected at both ends? Is it wired correctly (see page 39)? Ensure that all video connections throughout the system are attached securely.
30 SDMX PS/2 Mini Extender Range 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.
Troubleshooting 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.
32 SDMX PS/2 Mini Extender Range General Questions Is it possible to use a cable longer than 50m? It might be possible to use a longer cable at lower resolutions but video quality will degrade substantially beyond about 75m. 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.
