28 Configuration Activating or deactivating the video compression This function can only be (de)activated in the setup menu. The video signal usually is transmitted between the computer module and the user module in a compressed way. Due to this compression, the picture on the console monitors are normally displayed lossless and judder free. Under certain conditions, moving pictures can cause a special tearing effect on the monitors of the remote console. In this case, the monitor image consists of two subsequent frames that are partly displayed: The lower part of the picture shows a part of the old frame, the upper part shows a part of the new frame. At the point where both frames touch, the picture appears to be torn. In this case, deactivate the video compression to display the moving picture without the tearing effect. Note: The missing video compression causes a small juddering at the monitor of the remote console. How to (de)activate the video compression: setup menu 1. Establish the connection to the DVIVision system through the terminal emulation program. 2. Use the arrow keys to select the row Video Compression. 3. Press the Space key (repeatedly) to (de)activate the video compression: Enabled Disabled activates the video compression deactivates the video compression 4.

33 Configuration Activating or resetting a PS/2 mouse A PS/2 mouse can only be activated or reset in the setup mode. Unlike USB mouse devices, PS/2 mouse devices do not support the hot plug technology. You can therefore insert the PS/2 plug during operation but it may be possible that the computer does not detect the input device. To activate or reset the PS/2 mouse, a special command can be send to the computer through the DVIVision system. Since the commands differ depending on the used mouse type and the installed operating system, four different setup keys are provided. How to activate or reset a PS/2 mouse: setup mode 1. Press the key combination Hotkey + Backspace (default: Ctrl + Backspace) to activate the setup mode. If the hotkey delay is active, press the key combination for seven seconds. 2.

36 Continuative information Continuative information Recommendations for the twisted pair cable The transmission of all signals of the DVIVision system is carried out through one twisted pair cable (category 5e or better). The connection of several segments using patch panels and connection ports is permitted. However, connections through active network components such as network switches, hubs or repeaters are not permitted. The data transmission is reliable over a distance of at least 100 metres using a regular standard twisted pair cable (category 5e or better). The distance that can actually be achieved depends on the quality of the used cable. High-quality S-STP cables with an AWG22 wire gauge coding can bridge a distance of up to 140 metres. Patch cables with an AWG26 wire gauge coding can only bridge a maximum of 80 metres. To ensure reliable operation even in environments with interference, installation cables with at least AWG24 coding have to be used for lengths over 80 metres. Wire gauge Cable type Category Recommendation AWG22 Installation 5e, 6 or 7 up to 140 m AWG23 Installation 5e, 6 or 7 up to 130 m AWG24 Installation 5e, 6 or 7 up to 120 m AWG26/27 Patch cable 5e, 6 or 7 up to 80 m Table 2: Recommended cable lengths depending on the wire gauge The lengths that are mentioned in the table above must be interpreted as the sum of all segments between the devices. The following cables achieved the best results during test operation: up to 140 metres: Kerpen MegaLine G S/F AWG22 up to 100 metres: G&D K-C5-HR (see Order numbers on page 45) up to 80 metres: Dätwyler Uninet flex 4P, AWG26, S-STP 32 G&D DVIVision

37 Continuative information USB and PS/2 signals of the variants -ARU and -U If you use a variant of DVIVision that supports USB devices, it is necessarily required to connect the USB CPU interface of the computer module (DVIVision-CPU) with the USB interface of the computer. The data of the USB devices are transmitted to the computer through this interface. The signals of keyboard and mouse are also transmitted through this USB connection. If you prefer to transmit the signals of keyboard and mouse through the PS/2 interfaces, connect the interfaces Mouse CPU and Keyb. CPU with the PS/2 interfaces of the computer. Supporting any resolution In principle, the DVIVision system supports all resolutions that can be transmitted through a single link interface according to the DVI specification 1.0. This restriction mainly affects the pixel rate, which can reach from 25 MHz to 165 MHz. Therefore, resolutions between 640 x 480 pixels at 60 Hz and 1600 x 1200 pixels at 60 Hz are possible for the common timing standards by VESA DMT and VESA SMT x 1200 pixels at 60 Hz is transmitted according to VESA CVT-RB. Almost any refresh rate and resolution within the technical constraints are possible. The available display modes are largely dependent on the graphics card, the graphics driver, the operating system and the connected monitor. The video data that are transmitted from the computer to the computer module (DVIVision-CPU) are transferred to the monitor of the remote console with the same timing. The signal s frequency and display position at the computer module therefore correspond to those of the graphics output. Note: While generating the video signal, some graphics cards differentiate between digital and analog output. Such graphics cards generate digitally output image signals with partly non-standardised timings. Such timings do not comply with the monitor s default to reduce the frequencies of the digital signals. Normally, this does not affect the DVIVision system and the digitally connected displays. Due to the non-standardised timing, analog monitors might not be able to display the image size and the image position properly. G&D DVIVision 33
