AdderView DVI Installation and Use Page 24
3.4 Keyboard hotkey control
AdderView DVI can be conveniently controlled by selecting channel, autoscan mode
or security locking from the keyboard. 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 by reconfiguring the hotkeys (see section 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 DVI. 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
‘HOTKEYs’ and ‘A’ - selects autoscan mode where each channel is displayed for
the selected time (see section 4.2). To cancel autoscan mode simply select any
fixed channel either by hotkey or using the AdderView DVI 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.
‘HOTKEYs’ and ‘L’ - disables the AdderView DVI's keyboard and mouse and
displays 0. The video signal is switched off. If a password has not been set then the
AdderView DVI can be re-enabled by selecting a channel. If a password has been
set then the AdderView DVI displays 'P' to indicate that a valid password must be
entered to unlock the switch. Simply type the same key combination as was set
during configuration (see section 4.7) followed by the (return) key. Note - if anyone
has typed at the keyboard whilst in secure mode, it will be necessary to type (return)
first to clear the invalid password, then type the valid password followed by (return)
again.
