Configuration
Connecting to Digital iPEPS
Connection to (and configuration of) Digital iPEPS is carried out ov\
er a network, 
using a VNC Viewer program running on a computer or mobile device. VNC 
Viewers are available for most computers, tablets and smartphones.
•	 If	you	already	have	a	VNC	viewer,	please	follow	the	Initial	configuration	
instructions given on the next page.
If you do not already have a VNC viewer, there are three options:
•	 You	can	download	a	Windows	VNC	Viewer	from	the	Digital	iPEPS	itself.
•	 You	can	download	the	latest	VNC	Viewers	for	most	operating	systems	via	
the RealVNC website, or for tablets and smartphones from the appropriate\
 
app store.
•	 Without	downloading	anything,	you	can	run	a	Java	version	of	the	VNC	
Viewer inside your web browser.
To download a Windows VNC Viewer from the Digital iPEPS unit
Note: The version of VNC supplied within the Digital iPEPS supports audi\
o, 
however, audio is not supported in the later viewers from RealVNC.
1 Connect the Digital iPEPS to an IP network where a suitable computer 
is available on the same subnet (please see the Installation chapter fo\
r 
connection details).

Performing a flash upgrade
The firmware in Digital iPEPS is fully upgradable and there are two me\
thods that 
you can use:
•		 The	remote	method,	or
•		 The	‘dip	switch’	method.
The most streamlined upgrade procedure is the remote method because it i\
s 
carried out completely from a remote system. The ‘dip switch’ meth\
od is useful 
because it can be carried out even if the firmware within the Digital \
iPEPS unit 
has been corrupted.
Flash upgrade using the remote method 
Using this method, the Digital iPEPS is upgraded via remote connection (\
through 
the IP network port). Upgrades are digitally signed by Adder using a se\
cure key. 
This prevents unauthorised or altered firmware images being downloaded\
 into 
the unit.
To perform a flash upgrade
1  Download the latest firmware revision for the Digital iPEPS from the A\
dder 
website and decompress the download file. View the decompressed file\
s 
and make a note of the name and location of the .bin file that was par\
t of 
the download file collection.
2  Make a remote connection to the Digital iPEPS unit and login as the admi\
n 
user.
3  Once logged in, click the ‘Configure’ button in the top right co\
rner of the 
window.
4  Click the ‘Unit Configuration’ button.
5  Click the ‘Advanced Unit Configuration’ button.
6  Click the ‘Upgrade Firmware’ button. A dialogue box will be displa\
yed: 
7 Note the IP address shown in the dialogue box and click OK.
8  The unit is now ready to accept the upgrade files. Open your browser a\
nd 
log into the Digital iPEPS using the IP address that was confirmed in \
the 
dialog. Once connected, the unit will offer the following screen:
9  Click the ‘Browse’ button and locate the .bin upgrade file that \
you 
downloaded earlier. Click the ‘Perform Upgrade’ button. The upgrad\
e will 
take place and its progress will be shown on screen.
10   When the upgrade is complete, click the link ‘Click here to reboot th\
e unit 
into normal operation’.
Flash upgrade using the dipswitch method 
Use the dipswitch method if the firmware on the Digital iPEPS has beco\
me 
corrupted	and	there	is	no	access	from	a	VNC	session.	You	will	need	to	know	the	
IP address of the Digital iPEPS (the default IP is 192.168.1.42). 
1  With the power off, change dip switch 2 to ON.
2  Power On the Digital iPEPS.
3		Using	a	web	browser	go	to	the	IP	address	of	the	Digital	iPEPS.	You	should	
see the upgrade page as shown above.
4 Browse to the .bin file and then click the Perform upgrade button.

Operation
Using the viewer window
Once connected to the Digital iPEPS via the VNC Viewer (please see Connecting 
to Digital iPEPS for details), the viewer window gives you the ability to view 
and control the Digital iPEPS and its host computer(s). Its operation \
is almost 
identical	regardless	of	whether	you	used	the	VNC	viewer	or	your	Java	viewer	to	
display it.
The menu bar
The viewer window presents a menu bar similar to that shown below. Certa\
in 
items within the toolbar are displayed depending upon your access permis\
sions 
and/or the Digital iPEPS configuration.
When using the viewer window
What is the best screen resolution to use?
The best resolution for your computer is one that is larger than the scr\
een of the host 
computer that you are viewing. This will allow you to see everything wit\
hout scrolling 
around. Alternatively, the VNC viewer can be set to scale the image to fi\
t your screen, 
but remember that some pixel dithering effect will be seen when scaling \
is used. 
How do I navigate around a larger screen?
If the screen that you are viewing has a larger resolution than your vie\
wing 
window you will need to scroll around to see all items. The viewer windo\
w 
allows you to ‘bump scroll’ (only in full screen mode). This mea\
ns that when 
your mouse cursor bumps against the edge of the screen, the screen image\
 will 
scroll across automatically.  
How do I escape from full screen mode?
Press the F8 button. This button is changeable but is most often set to F8.  
How do I make the most of a slow connection?
The VNC viewer is slightly better suited to slower connections than the \
browser 
viewer because it offers more options. Click the Options button of the VNC 
viewer when entering the Digital iPEPS address during log on.  
Rate limit mouse events
When selected, this mode greatly reduces the mouse movement data that ar\
e 
sent to the host computer. When you move the local mouse, the remote cursor 
will catch up roughly once per second. 
For details about how to determine the options on the menu bar, see Editing the viewer window menu bar.
Re-sync mouseEnsures that the mouse pointer which you move and the mouse pointer on the host system are correctly synchronised. 
ControlsDisplays a menu of options concerning keyboard, video and mouse operation.
Access modeAllows you to choose between Shared and Private access modes.
Dialogue areaIndicates your username and the host system that you are currently viewing. This area can also display other messages.
ConfigureThis option is only available to the admin user and provides access to the main configuration menus.
Viewer options(VNC viewer only) Click the VNC icon to view the viewer window options.
PowerClick to access the power on/off options for the current host computer. 
HostsClick to display a list of computers. Choose an entry to connect to that host computer.
Ctrl Alt DelSends the Ctrl Alt Del sequence to the current host computer.
Auto calibrateThis button will calibrate the mouse, but only when relative mouse mode is selected.
Note: During initial use, neither the Hosts nor the Power buttons will be present.

Host selection
The Hosts button on the menu bar provides the quickest and most effici\
ent way 
to switch between host computers. This is because the button is close at\
 hand, 
but also because the screen calibration details for each host are reused\
 when 
this method of switching is used. 
Note: The Hosts button is displayed only when the switching details for \
two or 
more computers have been declared within the configuration section by \
the 
admin user. 
To select a host
1 Click the Hosts button to display a list of 
computers.
2 Click the required computer name to view and 
control it.
See Host configuration for details about 
programming new hosts into the Digital iPEPS (‘admin’ 
user status required).
Configure
This option is displayed only when you are logged on as the ‘admin’\
 user. When 
selected it provides access to a wide range of Digital iPEPS settings.
See Appendix 4 for more details.

Access mode - shared/private 
Up to four users can be simultaneously logged-in and all will view the s\
ame 
host. If you need to perform a sensitive task that should not be viewed \
by other 
users, you can change the access mode to Private. This action prevents o\
ther 
users connecting at the same time.  
To change the access mode
1 Click one of the arrow buttons adjacent to the 
Shared/Private indicator.   
Power switching
When configured (and where you have access rights) this option allow\
s you to 
control the mains power input to the currently selected host computer.
Note: This option is generally used to power cycle remote systems that h\
ave 
failed to respond. Before switching a system off, ensure that all attemp\
ts have 
first been made to power it down through normal means.
To switch a system on or off 
1 Use the Hosts button to select the required 
computer.
2 Click the Power button and then select the Switch 
on or Switch off option, as appropriate.
Auto calibrate  
Auto calibrate will calibrate the mouse only if relative mouse mode is s\
elected.
This detects the mouse motion and will report back that the mouse has be\
en 
calibrated correctly depending upon the operating system.
See the notes on Advanced mouse configuration for more details.
Once this has been done, providing you use the ‘Hosts’ button to s\
witch 
between host computers, the video settings for each machine will be re-u\
sed.  
Re-synchronise mouse  
If you find that your local mouse pointer and that of the host are not\
 correctly 
synchronised, use this feature to re-align their movements. This operati\
on is also 
selectable from the Controls menu.
To re-synchronise the mouse
1 Use the Hosts button to select the required computer.
2 Click the  button and then click OK in the subsequent pop-up message.
Note: If you find that this doesn’t work, you may need to perform a mouse\
 
calibration again.

Mouse Control
This option displays a mouse control dialogue and is useful when the rem\
ote 
cursor is failing to respond correctly to your mouse movements, even aft\
er using 
the Resync mouse option. 
The mouse control dialogue allows you to control the remote mouse cursor\
 
using a selection of buttons that you click with your local mouse. 
Controls
When clicked, this button reveals a menu of 
options concerned with keyboard, video and 
mouse operation.
Single Mouse Mode
This mode is for fast network connections where 
the cursor response is sufficient to provide instant 
visual feedback on the remote screen. When 
enabled, the cursor is ‘captured’ within the viewer 
window until you use the ‘escape’ hot keys.
To quit from single mouse mode, press F8 and then P. Alternatively, enab\
le and 
use the mouse button escape sequences - see Advanced unit configuration 
for details.  
The single mouse mode does not require calibration. 
Resync Mouse
This option has the same effect as the  button on the menu bar and re-
synchronises the local and remote mouse pointers. 
Refresh Screen
This option refreshes the whole screen image to remove any artefacts fro\
m 
moved screen items. This is useful when using very low refresh rates on \
slow 
speed communication links.
Click to move the remote mouse cursor up, down, left or rightClick to calibrate the remote mouse
Click to produce a single mouse click for the left, centre or right mouse buttons
Click to produce a continuous mouse click and hold for the left, centre or right mouse buttons
When ticked the unit will attempt to switch to Absolute Mouse mode (recommended). If the computer does not support this then it will display a warning and return to relative mouse mode. Click to display the Advanced Mouse Configuration dialogue. See next page.

Info
When selected, this option displays an information dialogue showing the \
current 
logged on users, the current host, its video mode and its mouse motion d\
etails.
Advanced mouse configuration
This dialogue allows the mouse acceleration to be configured according\
 to 
the operating system in use and also permits manual fine tuning for si\
tuations 
where problems are encountered with the Calibrate function.  
For best results, choose the appropriate Change motion: entry to match the host 
in use.
The available Change Motion schemes are: Constant, XFree86, Windows Pre-XP, 
Windows XP, Windows XP SP2, OS/2, Solaris, Solaris 9 and Mac OSX. Most of 
these offer the Speed setting as the only option, however, the Windows Pre-Xp 
and XFree86 options contain many other parameters.
When the Absolute Mode option is ticked in the main Mouse Control menu, 
this dialogue allows you to adjust the Absolute Offset scale:

Keyboard Control
This option displays a keyboard control dialogue and is useful for sendi\
ng 
keyboard combinations (to the host) that are needed regularly or that \
are 
trapped by the Digital iPEPS.
When entering codes: 
+  means press down the key that follows
–  means release the key that follows
+–  means press down and release the key that follows
*  means wait 250ms (note: if a number immediately follows the asterisk, t\
hen   
the delay will equal the number, in milliseconds)
It is automatically assumed that all keys specified will be released a\
t the end, so 
there is need to specify -Ctrl or -Alt if these keys are to be released \
together.
Examples:
‘Ctrl + Alt 12’ would be expressed as: +Ctrl+ Alt+1–1+2
+N means press the ‘N’ key
+Scroll means press the Scroll lock key
+Space means press the space key

Ignore DitheringThe ‘Ignore Dithering’ option increases performance and reduces ne\
twork traffic when the host computer is an Apple Mac or another computer tha\
t has dithered video output. It also improves performance if the video sou\
rce is noisy (e.g. from a camera or a VGA-to-DVI converter).
Video settings
This option provides a range of options related to the video configura\
tion.
Dithering is a technique used by some graphics cards to improve perceive\
d 
image quality by continuously slightly varying the colour of each pixel.\
 This gives 
the illusion of more shades of colour than the display can really reprod\
uce, and 
smooths the appearance of gradually shaded areas in images. Unfortunatel\
y, 
dithering is an issue for KVM extenders such as Digital iPEPS because it\
 makes 
the image appear to be changing all the time even when it is static. Thi\
s means 
that a great deal of unnecessary network data is sent to the VNC viewer,\
 
reducing the video frame rate and making mouse response appear slow.
The Ignore Dithering option works by ignoring small variations in the video 
from frame to frame. It is disabled by default to give full colour accur\
acy and the 
best possible frame rate from non-dithered video sources.
The Threshold setting adjusts the level of dithering noise that is ignored. The 
‘Auto’ button attempts to choose a suitable value automatically, b\
ut the level 
can also be adjusted manually using the slider or arrow buttons. The bes\
t value 
is of course a compromise between capturing all the ‘real’ screen \
changes whilst 
ignoring the (almost invisible) dithering noise. A good way to choose \
the value 
is to watch the Display Activity indicator for a static screen. If the Threshold 
is too low, the Display Activity will be a high percentage while nothing\
 is really 
changing. If the Threshold is too high, the Display Activity will be ver\
y low (or 
zero) but some real changes in the screen may be missed.
Note: If using the Paste Clipboard feature, within the VNC viewer proper\
ties, 
ensure that in the Inputs section, the Share clipboard with server option is 
enabled. See Appendix 1 for details.
