2.12  Upgrading the SmartViews flash memory
The SmartView Multiscreen uses flash memory technology which enables the
firmware code to be upgraded by the user. Upgrades are performed by connecting a
PCs serial port to the SmartViews options port and running an upgrade program on
the PC. This upgrade program downloads the new firmware to the SmartView and
checks that the data has been programmed correctly. 
						

							SmartView MultiscreenInstallation and UsePage 21To perform a firmware upgrade on your SmartView Multiscreen you will need a
suitable serial upgrade cable and an IBM PC compatible computer with an RS232
serial port and an operating system that supports DOS. Upgrade cables may be
purchased for Adder Technology or may be made using the wiring specification
given in Appendix A4. You will also need to download the latest version of the
SmartView Multiscreen firmware which is available free of charge at
www.addertec.com.
To perform a flash upgrade on the SmartView Multiscreen:
Step 1 - Connect your computer to the SmartView
Connect your computers serial port to the SmartView Multiscreens options port
(labelled OPTIONS/FLASH).
Step 2 - Select flash upgrade mode using option switch 7
Move option switch 7 on the underside of the SmartView Multiscreen to the ON
position.
Step 3 - Reset the SmartView Multiscreen
Reset the SmartView Multiscreen by moving option switch 8 to the ON position (halt
and reset) and then back to the OFF position (normal operation). Alternatively you
may reset the SmartView by powering off all the attached computers and removing
the optional power adapter.
Step 4 - Ensure that the SmartView is powered on
Ensure that the SmartView is powered on. It is normally possible to upgrade the
SmartView when it is powered from a single computer, however it is good practice to
ensure that there is the maximum possible power availability during flash upgrades
and so if possible ensure that all the computers are powered on. The upgrade
program monitors the SmartViews voltage and will not allow an upgrade to be
performed if the voltage is insufficient.
The display should now show: 
						

							SmartView MultiscreenInstallation and UsePage 22Step 5 - Run the upgrade program
The latest version of the SmartView Multiscreen firmware is available from the Adder
Technology website at www.addertec.com. The SmartView Multiscreen uses the
same firmware as the AdderView GEM product. The program and data files are
supplied as a pair e.g.
AVG129.EXEAVG129.HEX
and should be downloaded to the same directory on your PC. Run the file
AVGxxx.EXE (e.g. AVG129.EXE) and follow the on-screen instructions. During the
upgrade the display will show an upper case U and the dot will flash to show that the
upgrade is in progress.The display will again show a lower case U when the download is complete. Move
option switch 7 to the OFF position to exit upgrade mode and start normal operation.
You may check the new firmware version by entering configure mode and using the
firmware version query function.
Some useful issues to bear in mind when performing flash upgrades
The upgrade program rewrites the SmartViews firmware code. If the upgrade
process is interrupted then the SmartView will have invalid code and will not be able
to operate. It is therefore good practice to ensure that the upgrade process is always
fully completed. A partial or failed upgrade may be rectified by performing another
upgrade. If the upgrade process is interrupted accidentally then you should
immediately repeat the upgrade process without moving switch 7 from the flash
upgrade (ON) position. Switch 7 forces the SmartView into flash upgrade mode and
prevents the upgraded code from being run. Running faulty or partially upgraded
code may have unpredictable results and may damage your SmartView or
computing equipment. For obvious reasons, the code that the SmartView uses to
perform upgrades is not itself upgradeable - a common problem on some flash
upgradeable products that could effectively be destroyed by a partial upgrade!
WARNING - Running faulty or partially upgraded code may have unpredictableresults and may damage your SmartView or computing equipment. 
						

							SmartView MultiscreenInstallation and UsePage 233. Using the SmartView MultiscreenThis section explains the general operation of the SmartView Multiscreen. We
recommend that you read this section before starting to use the product.
3.1 Power on status
At power on the SmartView Multiscreen selects computer 1 and displays 1. If a
password has been set then ‘P’ will be displayed and the SmartView Multiscreen will
remain locked until a valid password is entered.3.2 Front panel key and remote controller
The front panel key is used to select which channel is currently controlled by the
shared keyboard, mouse and monitor ports. Pressing the key during normal
operation will cause the next channel to be selected.
The key can also be used to access the SmartView Multiscreen’s configuration
mode (see section 2.6). To do this press the key and hold it down for 5 seconds until
‘C’ appears on the SmartView Multiscreen’s front panel display.
An optional remote controller is also available which replicates the front panel key
and display, but can be located remotely from the SmartView Multiscreen. This is 
						

							SmartView MultiscreenInstallation and UsePage 24particularly useful in applications where the SmartView Multiscreen is located away
from the 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.
3.3 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 SmartView
Multiscreen has been locked, ‘P’ will be displayed until a valid password has been
typed to unlock the unit. Data flow from the mouse or keyboard causes the dot to
flash. 
						

							SmartView MultiscreenInstallation and UsePage 253.4 Switching operation
When you select a port, your keyboard and mouse will control the computer that is
connected to that port and the video feeds from that that computer will be displayed
on the monitors. For example, if you select channel 2 then the video signal arriving
at port 2A will be sent to the monitor that is attached to port A. Video arriving at ports
2B, 2C and 2D will be displayed on the monitors attached to ports B, C and D
respectively.
3.5 Keyboard hotkey control
SmartView Multiscreen 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 SmartView
Multiscreen. 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 SmartView Multiscreen 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 SmartView Multiscreens keyboard and mouse 
						

							SmartView MultiscreenInstallation and UsePage 26and displays 0. The video signal is switched off. If a password has not been set then
the SmartView Multiscreen can be re-enabled by selecting a channel. If a password
has been set then the SmartView Multiscreen 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.
Examples of common hotkey sequences (assuming CTRL + ALT hotkey option):
To select channel 2:
pressba2 ba2
release 2ba 2ba
To tab through channels:
pressba ba
 v v
 release v v
 pressv v
release v v
 pressv v
release vba vba
3.6 Mouse control
Computers may conveniently be selected using a three button mouse. In order to
switch to the next computer simply hold down the central mouse button (the wheel
mouse button on an IntelliMouse) and click on the left hand mouse button to select
the next computer or the right hand mouse button to select the previous computer. If
the SmartView has been set to scan active ports then the next or previous active
channel will be selected. If it has been set to scan all ports then the next or previous
numerical channel in sequence will be selected (see section 4.5 for more details).
Mouse switching may be enabled or disabled by setting options during configuration
(see section 4.3). When mouse switching is disabled the third button or wheel button
state is ‘passed through’ the SmartView and seen by the application software.

3.7 RS232 control
SmartView Multiscreen can be controlled by a remote RS232 device. To select a
channel the data rate of the sending device must be set to 1200 baud, 8 bits, no
parity and 1 stop bit. No handshaking is used by the SmartView Multiscreen. Simply
send the character for the channel which needs to be selected, for example ASCII
‘1’ (hex code 31) will select channel 1, ASCII ‘2’ (hex code 32) will select channel 2
and so on. The SmartView will echo the ASCII character back to the sending device
when the channel has been changed. The serial interface pins are found on the
options connector on the rear of the SmartView. Pin assignments for this connector
are given in appendix A.
3.8 Cascading SmartView Multiscreens
SmartView Multiscreen switches can be connected together to expand the number
of connected computers. When cascading SmartView Multiscreens a power adapter
(SVMSPSU) must be connected to each SmartView Multiscreen. SmartView
Multiscreens can be connected in a cascaded tree structure. This can be particularly
useful where clusters of computers are located some distance from each other
because each unit acts as data booster and can each be up to 30 metres away from
the next SmartView Multiscreen. The channel can be selected on remote SmartView
Multiscreen units using an extension of the HOTKEY control . 
						

							SmartView MultiscreenInstallation and UsePage 28A typical cascade of two SmartView Multiscreens
For example, consider a situation where two SmartView Multiscreen units are
connected together as shown above. To connect to the computer attached to port 3
on SmartView Multiscreen B the user would hold down the hotkey keys then press
‘2’ followed by ‘3’, whilst keeping the hotkey keys pressed. This will have the effect
of connecting to port ‘3’ of the SmartView Multiscreen which is connected into port 
						

							SmartView MultiscreenInstallation and UsePage 29‘2’ of the first SmartView Multiscreen unit A.
For example to connect to port 3 on the SmartView Multiscreen cascaded off port 2
of your first SmartView Multiscreen use:
pressba ba

press3 3release 3 3ba ba
3.9 Synchronising SmartView Multiscreens for applications that
require synchronised switching of more than four monitors
A single SmartView Multiscreen supports up to four monitors. For applications that
require switching of more than four monitors, multiple SmartViews may be
connected together so that they operate in a synchronised manner. Whenever the
SmartViews channel is switched it sends an RS232 command out on its serial
interface. The SmartView switches its channel if it receives the same command on
its serial interface. Consequently, by linking the serial interfaces a master unit may
be made to automatically switch a daisy chain of slaved units as shown in the
diagram below. The slave units will require the optional power adapters because
they cannot draw their power from the video link alone.
The SmartView Multiscreen may also be synchronised together with AdderView
GEM products as their OPTIONS ports operate in the same way.
