Unit configuration
This page provides access to a selection of both basic and advanced sett\
ings for 
the Digital iPEPS. Many of the settings displayed here are also accessib\
le through 
the on-screen menu.
Unit Name
The name entered here will be displayed on the local menus and the remot\
e 
VNC viewer/browser windows.
New Connections Private
Allows you to determine whether new local or VNC connections should be s\
et 
up as private (when ticked) or as shared (when unticked).
Menu Bar Toggle Hot Key
Determines the function key that can be used to display/hide the menu ba\
r 
within the VNC screen.
Encryption
Three options are available: Always on, prefer off, prefer on. The one t\
o choose 
depends on the specific details of your installation. The use of encry\
ption 
imposes a slight performance overhead of roughly 10% but is highly secur\
e 
against third party intrusion.
Number of simultaneous VNC Users
Allows you to restrict the number of concurrent VNC sessions. The maximu\
m 
number (and the default setting) is 4.
VNC Viewer Hot Key Sequence
When using the VNC Viewer, you can use key press combinations to select \
host 
computers and also to display the host selection menu. This option allow\
s you 
to choose which keys should be used to form the hotkeys that will preced\
e a 
switching command. The default setting is CTRL + ALT, so as an example w\
hen 
you press the CTRL  ALT and 2 keys, the viewer will change to the host w\
ith 
“Hotkey Host Number” 2 - see Host configuration. 
EDID Configuration   
Advanced Unit Configuration

EDID configuration
Click this button to display advanced EDID options that do not normally \
require alteration.
This page allows you to edit the contents of the EDID records that are u\
sed to 
inform the computer of the supported video modes. The default EDID shoul\
d be 
sufficient for the vast majority of situations. If necessary, use the \
Edit Preferred and 
Standard Timing button fine tune settings to support specific situat\
ions.
When you click the Save button, the EDID information within the unit wil\
l be 
updated. As the EDID is usually only read when a computer is booted, it \
may be 
necessary to power cycle the host computer to make it re-read the new ED\
ID.

Advanced unit configuration
Click this button to display advanced options that do not normally requi\
re alteration.Background Refresh Rate
Use the arrow keys to alter the background refresh rate used to correct \
any 
screen changes missed in normal operation. The options are: Slow, Medium\
, 
Fast, Auto or Disabled. The Auto option automatically varies the refresh rate 
when multiple VNC sessions are active to provide a balance between the 
sessions. 
Note: When a low connection speed is detected, the background refresh is\
 
automatically disabled, regardless of the settings of this option.
Mouse Latency Allowance
This option is used during calibration to account for latency delays tha\
t may be 
caused as signals pass through a device. 
During calibration, the Digital iPEPS waits for 40ms after each mouse mo\
vement 
before sampling the next. If a device adds a significant delay to the \
flow of data, 
the calibration process can be lengthened or may fail entirely. The value entered 
here is added to (or subtracted from) the default 40ms sampling time.
Note: You can enter negative values (down to -40) in order to speed up\
 the 
calibration process when using fast KVM switches. Use this option with c\
aution 
as it can adversely affect the calibration process.
Mouse Rate
Defines the rate at which mouse movement data are transmitted to the s\
ystem. The 
default option is 20ms, which equates to 50 mouse events per second. This is used to 
slow down the rate in exceptional circumstances but normally requires no\
 adjustment.       
Single Mouse Mode Mouse Switch
Select the mouse button combination to exit from single mouse mode (whe\
n active). 
Use Quick Mouse Calibration
Invokes optimised calibration techniques that handle the majority of mou\
se types. 
Behaviour for admin connections when limit reached
Determines what should occur when four global connections already exist \
and 
a fifth, administrator connection attempt is made. Options are: Replace oldest 
connection, Replace newest connection and Don’t replace. Only non-administrator 
connections can be terminated in this way.
Use VESA GTF
When ticked, the VESA Generalized Timing Formula will be used to help 
determine the correct input video resolution and timing details. 
Upgrade firmware
Places the unit into upgrade mode. See Upgrading Digital iPEPS.     
Reset Unit
Performs a complete cold boot of the Digital iPEPS unit. 
Force VNC Protocol 3.3
IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a \
legacy 
version that does not offer any encryption.
Idle Timeout
Determines the period of inactivity on a global connection before the us\
er is logged 
out. The idle timeout period can be set to any time span, expressed in m\
inutes.
Session Sleep Timeout
Determines the period of inactivity before the viewer screen will blank \
and a 
message is displayed. When no hosts are being viewed either because of t\
his 
time out or if no viewers are active then parts of the video circuitry a\
re powered 
down reducing power consumption by up to a third.
Protocol Timeout
Sets the time period by which responses should have been received to out\
going 
data packets. If the stated period is exceeded, then a connection is con\
sidered 
lost and terminated.

Time & date configuration
This page allows you to configure all aspects relating to time and dat\
e within the unit.
Note: The unit has a real-time clock which will maintain the date and ti\
me for a 
few hours without power.
Set Time from NTP Server
Click to immediately use the time and date information from the listed N\
TP server. 
Timezone specifier
Optionally enter a recognised timezone specifier related to the curren\
t position 
of the Digital iPEPS unit. When an NTP server is used, the specifier w\
ill be used 
to provide the correct real time.
The timezone specifier takes the following form: 
     std offset dst [offset],start[/time],end[/time]
The std and offset specify the standard time zone, such as GMT and 0, or CET 
and -1, or EST and 5, respectively. 
The dst string and [offset] specify the name and offset for the corresponding 
Daylight Saving Time zone; if the offset is omitted, it defaults to one hour ahead 
of standard time. 
The remainder of the specification describes when Daylight Saving Time\
 is in 
effect. The start field is when Daylight Saving Time goes into effect and the 
end field is when the change is made back to standard time. The most comm\
on 
format used for the daylight saving time is: Mm.w.d 
Where: m specifies the month and must be between 1 and 12. The day d 
must be between 0 (Sunday) and 6. The week w must be between 1 and 5; 
week 1 is the first week in which day d occurs, and week 5 specifies the last d 
day in the month. 
The time fields specify when, in the local time currently in effect, the chang\
e to 
the other time occurs. If omitted, the default is 02:00:00. 
Typical examples are:
UK:     GMT0BST,M3.5.0/1,M10.5.0/2
Central Europe:      CET-1CEST,M3.5.0/2,M10.5.0/3
US Eastern:      EST5EDT,M3.2.0/2,M11.1.0/2
US Pacific:      PST5PDT,M3.2.0/2,M11.1.0/2

Network configuration (IPV4)
This page allows you to configure the various aspects of the IP port w\
hen it is 
used in IPV4 mode. For IPV6 mode, please see the next page.
MAC address
Media Access Control address – this is the unique and unchangeable co\
de that 
was hard coded within your Digital iPEPS unit when it was built. It cons\
ists of 
six 2-digit hexadecimal (base 16) numbers separated by colons. A secti\
on of the 
MAC address identifies the manufacturer, while the remainder is effect\
ively the 
unique electronic serial number of your particular unit.  
Use DHCP
DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. It\
s function is 
particularly useful when connecting to medium size or larger networks.  
When this option is selected, your Digital iPEPS will attempt to locate \
a DHCP 
server on the network. If such a server is located, it will supply three\
 things to 
the Digital iPEPS: an IP address, an IP network mask (also known as a S\
ubnet 
mask) and a Gateway address. These are not usually granted permanently,\
 but 
on a ‘lease’ basis for a fixed amount of time or for as long as \
the Digital iPEPS 
remains connected and switched on. Discover allocations.
IP Address
This is the identity of the Digital iPEPS within a network. The IP addre\
ss can 
be thought of as the telephone number of the Digital iPEPS. Unlike the 
MAC address, the IP address can be altered to suit the network to which \
it is 
connected. It can either be entered manually or configured automatical\
ly using 
the DHCP option. When the DHCP option is enabled, this entry is greyed o\
ut.
IP Network Mask
Also often called the subnet-mask, this value is used alongside the IP a\
ddress 
to help define a smaller collection (or subnet) of devices on a netw\
ork. In this 
way a distinction is made between locally connected devices and ones tha\
t are 
reachable elsewhere, such as on the wider Internet. This process helps t\
o reduce 
overall traffic on the network and hence speed up connections in gener\
al.
IP Gateway
This is the address of the device that links the local network (to whic\
h the Digital 
iPEPS is connected) to another network such as the wider Internet. Usua\
lly the 
actual gateway is a network router and it will be used whenever a requir\
ed 
address lies outside the current network.  
VNC Port
This is the logical link through which communications with a remote VNC \
viewer 
will be channelled. The default setting is 5900 which is a widely recogn\
ised port 
number for use by VNC software. However, in certain circumstances it may\
 be 
advantageous to alter this number - see ‘Security issues with ports’\
 for more 
details.  
HTTP Port
This is the logical link through which communications with a remote web \
browser will be channelled. The default setting of 80 is an established \
standard 
for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed 
to suit your local network requirements.
IP Access Control
This section allows you to optionally specify ranges of addresses which \
will or 
won’t be granted access to the Digital iPEPS. If this option is left unchang\
ed, 
then the default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access f\
rom all IP 
addresses will be permitted. See Setting IP access control for details.

Network configuration (IPV6)
This page allows you to configure the various aspects of the IP port w\
hen it is 
used in IPV6 mode. For IPV4 mode, please see the previous page.
MAC address
Media Access Control address – this is the unique and unchangeable co\
de that 
was hard coded within your Digital iPEPS unit when it was built. It cons\
ists of 
six 2-digit hexadecimal (base 16) numbers separated by colons. A secti\
on of the 
MAC address identifies the manufacturer, while the remainder is effect\
ively the 
unique electronic serial number of your particular unit.
Enable IPV6
Change	this	option	to	Yes	only	if	the	Digital	iPEPS	unit	is	connected	to	an	IPV6	
compliant network.
IPV6 Addresses
This section is used to hold the IPv6 addresses for the Digital iPEPS. A\
 link 
local IPv6 address is automatically added using the Stateless Address Auto 
Configuration protocol. Use the Add, Remove, Edit buttons to alter the address 
as necessary.  
To get here
1 Using VNC viewer or a browser, log on as the ‘admin’ user.
2 Click the ‘Configure’ button in the top right corner.
3 Click the ‘Network Configuration’ option.
4 Click the ‘IPV6’ tab.
Use DHCPv6
When	this	option	is	set	to	Yes,	the	Digital	iPEPS	will	attempt	to	locate	a	DHCPv6	
server on the network to derive a unique IPv6 address for itself as well\
 as an 
address for the IPv6 Gateway. These are not usually granted permanently,\
 but 
on a ‘lease’ basis for a fixed amount of time or for as long as \
the Digital iPEPS 
remains connected and switched on. Discover allocations.
If this option is set to No, the Digital iPEPS will use the Stateless Address Auto 
Configuration protocol to determine its own IPv6 address. This will be shown 
in the IPV6 Addresses field and can be edited if necessary. 
IP Gateway
This is the address of the device that links the local network (to whic\
h the Digital 
iPEPS is connected) to another network such as the wider Internet. Usua\
lly the 
actual gateway is a network router and it will be used whenever a requir\
ed 
address lies outside the current network.  
VNC Port
This is the logical link through which communications with a remote VNC \
viewer 
will be channelled. The default setting is 5900 which is a widely recogn\
ised port 
number for use by VNC software. However, in certain circumstances it may\

Setting IP access control
The golden rule with this feature is ‘Include before you exclude’ \
or to put it 
another way ‘Arrange allowed addresses in the list before the denied addresses’. 
This is because the positions of entries in the list are vitally importa\
nt. Once a 
range of addresses is denied access, it is not possible to make exceptio\
ns for 
particular addresses within that range. For instance, if the range of ad\
dresses 
from A to F are denied access first, then the address C could not be g\
ranted 
access lower down the list. Address C needs to be placed in the list bef\
ore the 
denied range.
IMPORTANT: This feature should be configured with extreme caution as i\
t is 
possible to deny access to everyone. If such an error occurs, you will n\
eed to 
perform a reset to factory default settings in order to regain access.
To define a new IP access control entry
1 Click the Add button to display a popup dialogue:
2 Enter the base network address, the mask and select the appropriate acce\
ss 
setting.
3 Click the OK button.
To reorder access control entries
IMPORTANT: When reordering, ensure that any specific allowed addresses\
 are 
listed higher in the list than any denied addresses. Take care not to in\
voke any 
deny access settings that would exclude valid users.
1  In the access control list, click on the entry to be moved.
2 Click the Up or Down buttons as appropriate.
To edit/remove access control entries
1 In the access control list, click on the appropriate entry.
2 Click either the Edit or Remove button as appropriate.
Network/AddressEnter the network address that is to be allowed or denied access. If a range of addresses is being specified then specify any one of the addresses within the range and use the Mask entry to indicate the size of the range.
MaskEnter an IP network mask that indicates the range of addresses that are to be allowed or denied access. For instance, if only a single specified IP address were to be required, the mask entry would be 255.255.255.255 in order to specify a single location.
AccessUse the arrow buttons to select either ‘Allow’ or ‘Deny’ as appropriate.
In the list, access control addresses prefixed by ‘+’ are allow \
entries while those 
prefixed by ‘– ‘ are deny entries.
