For example, if you are printing from the old computer and you switch to a new computer before the print job is complete then only part of your print job will actually be printed. In particular you should avoid switching computers whilst a computer is reading or writing data to a USB data storage device such as a ZIP drive. Where practical it is adviseable to eject removable disks on USB drives before switching computers. 3.4 Status display The status display usually shows the currently selected port. If autoscan mode is selected, the segments will illuminate in sequence in a clockwise direction interspersed with a display of the currently selected channel. If the AdderView is waiting for the enumeration guard process to complete then the display will flash. Data flow from the mouse or keyboard attached to the PS/2 style keyboard and mouse ports (model AV4USB-PC only) causes the dot in the lower right hand corner of the display to flash. AdderView USB Installation and Use Page 20 AdderView USB Installation and Use Page 21 3.5 Keyboard hotkey control (model AV4USB-PC only) The AdderView may be conveniently controlled by pressing keyboard hotkey combinations on the keyboard attached to the PS/2 style keyboard port (see figure 4). All of the hotkey control commands are invoked by holding down the two hotkeys and then pressing a command key. By default, the two hotkeys are ‘CTRL’ and ‘ALT’, although other combinations can be selected (see section 2.4.4). Once the hotkey command has been activated you will need to release the hotkeys and the command key before a new hotkey command is accepted by the AdderView. HOTKEYs + TAB is an exception and this allows you to 'tab through' the ports by holding down the hotkeys and repeatedly pressing TAB. The hotkey command are summarised below (note that the numbers on the numeric keypad do not form part of a valid hotkey) : ‘HOTKEYs’ and ‘1’ - selects channel 1 ‘HOTKEYs’ and ‘2’ - selects channel 2 ‘HOTKEYs’ and ‘3’ - selects channel 3 ‘HOTKEYs’ and ‘4’ - selects channel 4 ‘HOTKEYs’ and ‘TAB’ - selects the next channel. The next channel may be the next active channel or the next channel in numerical sequence depending upon the position of option switch 8 (see section 2.4.3). ‘HOTKEYs’ and ‘A’ - selects autoscan mode where each channel’s video is displayed for the selected time (see section 2.4.2). To cancel autoscan mode simply select any fixed channel either by hotkey or by using the front panel button. ‘HOTKEYs’ and ‘0’ – switches off the video signal and displays 0. This will cause some monitors to go into standby mode or switch off. The video signal can be re- enabled by selecting a channel. Examples of common hotkey sequences (assuming CTRL + ALT hotkey option): To select channel 2: press ba baba2 22 release 2 22ba baba To 'tab through' channels: press ba babav vvrelease v vvpress v vv release v vvpress v vvrelease vba vbavba AdderView USB Installation and Use Page 22 3.6 Mouse control (model AV4USB-PC only) The AdderView’s channels may be changed using a three button mouse or IntelliMouse. In order to switch to the next channel simply hold down the central mouse button or wheel button and click on the left hand mouse button. The channel will then change to the next channel. The next channel may be the next active channel or the next channel in numerical sequence depending on the setting of option switch 8 (see section 2.4.3). 3.7 Autoscan mode Autoscan mode may be selected by holding the front panel key down for 5 seconds or by using the keyboard hotkeys. When autoscan mode has been activated the front panel display will alternately show a rotating segment and the currently selected channel. The video from each computer will be displayed for the time period selected by option switch 7 (either 2 seconds or 5 seconds). During autoscan all the USB peripherals remain disconnected and only the video signals are switched through. Depending upon the position of option switch 8, the AdderView will lock-on to all the computer ports or just the active computer ports. Many modern monitors are fitted with automatic power save relays and will switch off after a few seconds if connected to an inactive PC. If you are using such a monitor you must not scan inactive ports. Constant switching on and off of your monitor's relay will eventually damage your monitor. 3.8 The optional remote controller An optional remote controller is available which replicates the front panel key and display, but can be located remotely from the AdderView. The remote controller plugs into the options port on the back of the AdderView (see figures 1 and 2). This remote controller is particularly useful in applications where the AdderView is located away from the user’s desktop. The remote controller can be conveniently attached to your keyboard with a couple of Velcro strips to give instant channel information and key control. The key and display on the remote controller perform exactly the same function as...
