Sound control
This option provides a range of options related to the audio capabilitie\
s of the 
Digital iPEPS.
FormatuLaw - Use when transmitted data needs to be minimised - 8-bit compressed data.
Linear - Use when high quality audio performance is required - 16-bit uncompressed (raw) data is transmitted.  
Sample rateThe number of audio samples per second (in Hz). 8000 produces less samples and hence uses less network bandwidth. 48000 (48KHz) produces the best sound reproduction. 
ChannelsAllows you to choose between Mono and Stereo. 
Window size (ms)The time frame in which the unit requires an acknowledgement from the remote viewer when data is sent. If acknowledgements are not received, the unit will stop sending audio data - Click the Restart Sound button.
ThresholdThe level above which the audio level should be before it is considered to be not background noise and hence should be transmitted. A level of 25 means the audio input needs to be above 25% of the maximum before it is transmitted.
Min burst (ms)The time period for which the audio input must fall below the threshold level before audio transmission ceases. Transmission will begin again as soon as the threshold level is once again exceeded.  
Settings can be adjusted to suit transmission characteristics and audio \
quality 
requirements (unsuitable audio settings can affect video quality):
For maximum audio quality:
Format:  Linear 
Sample rate:  48000 
Channels:  Stereo
For use on slow links:
Format:  uLaw 
Sample rate:  8000 
Channels:  Mono
Where necessary, adjust the Window size, Threshold and Min burst setting\
s until 
optimum audio output is obtained.
Restart SoundClick to re-enable audio transmission following an automatic cutout. If cutouts occur regularly, try reducing the sample rate or format, or increasing the Window size setting.
Halt timeoutDetermines how long to wait once the audio input has stopped before timing out the audio connection. There are four options: Off, Short, Medium and Long.

Virtual Media 
The Adder Virtual Media feature allows you to remotely make files avai\
lable 
to a host computer that is linked to the Digital iPEPS. Disk drives, sin\
gle files 
or collections of files and folders up to 2GB in size can be mounted v\
ia the 
VNC link, and appear as a read-only disk on the host. This can prove to \
be an 
invaluable tool when upgrading host computers from remote positions. 
Note: The file transfer is in one direction only, from viewer to host.\
Note: Adder Virtual Media does not currently work with Apple Mac systems\
. 
In order to use the Adder Virtual Media feature, the VM link must be mad\
e 
between the Digital iPEPS and a USB port on the host computer. See Host 
computer connections for details.
There are two main ways to use Adder Virtual Media: 
•		 Create	a	read-only	‘virtual	disk	drive’	on	the	host	from	one	or	more	files	
chosen at the viewer end. This is useful for copying one or more files\
 from 
the computer running the VNC viewer to the host computer. See below.
•		 Export	a	disk	drive	(e.g.	CD,	DVD	or	USB	flash	drive)	from	the	viewer	
computer so it appears as a disk on the host attached to Digital iPEPS. \
A 
particular use for this is for booting or upgrading the remote host from\
 a CD 
or other media that you have at the viewer end. See next page.
Remotely transferring files to the host as a virtual disk drive 
There are several methods of doing this. The easiest method depends on w\
hether:
•	 The	files	are	already	on	the	clipboard	of	the	viewer	computer	(following	an	
Edit -> Copy operation). See To remotely transfer files from the clipboard >> 
or 
•	 The	files	still	need	to	be	selected.	See	To select and remotely transfer files 
from the viewer computer >>
To remotely transfer files from the clipboard 
1 On the remote system, log into the Digital iPEPS using the VNC viewer. 
2  If not already done, use Windows Explorer to locate and copy the require\
d 
file(s), or folder(s) to the clipboard. 
3 Within the VNC viewer window, click the Controls button and then select 
the Virtual Media option. A popup similar to the following will be displayed: 
 Click the Create VM Drive button to announce file availability to the host 
computer, whereupon a popup will confirm that the new virtual media di\
sk 
is built. 
 Note: Remember, at this point the selected files/folders have not yet \
been 
transferred to the host system, they are just visible there. 
4  On the host computer (via the VNC viewer) locate the new virtual drive\
 
(shown as a Removable Disk) and copy the files to the required location on 
the host computer. 
To select and remotely transfer files from the viewer computer
1  On the remote system, log into the Digital iPEPS using the VNC viewer. 
2  Invoke the “Send Files” feature of the VNC viewer (called “Fil\
e Transfer” in 
later versions), either by clicking the icon on the viewer’s toolbar\
 or selecting 
from the F8 menu. 
3  The viewer will display a window allowing you to select files or a who\
le folder. 
  Highlight the required files or folders (up to a maximum of 2GB) tha\
t you 
wish to transfer to the host computer and click the Open button. The new 
disk drive should appear on the host a few seconds later. 
 Note: The Use Entire Folder button provides a quick way to select a whol\
e 
folder while you are viewing its contents.
 Note: Remember, at this point the selected files/folders have not yet \
been 
transferred to the host system, they are just visible there. 
4  On the host computer (via the VNC viewer) locate the new virtual drive\
 
(shown as a Removable Disk) and copy the files to the required location on 
the host computer. 
Note: When using Adder Virtual Media features, within the VNC viewer 
properties, ensure that in the Inputs section, the Share clipboard with server 
and the Enable file transfer options are enabled. See Appendix 1 for details.

Remotely exporting a disk drive to the host
1 On the remote system, log into the Digital iPEPS using the VNC viewer. 
2  Press F8 and then V to display a Virtual Media dialogue box: 
Remote Drive(s)This section lists any located storage devices on the remote system that are 2GB or less, and which could be copied en masse to the host computer, if desired.
Remote Files or FoldersClick Browse to search for and select single or multiple files/folders to be copied to the host computer.
When the Create ISO Image option is ticked this creates a bootable disk so that it’s possible to boot the host computer from the virtual media drive.
3		You	can	select	an	entire	drive	or	a	disk	image	(e.g.	.iso)	file:	
•	 Select	a	disk	drive:	Click	the	checkbox	adjacent	to	the	listed	disk	drive	
that you wish to make available to the host computer, 
or 
•	 Add	a	Disk	Image	File:	Select	the	disk	image	file	and	click	Open.
4  In the Virtual Media dialogue box, click the OK button to announce the 
availability of the drive to the host computer. On the host computer, th\
e 
new drive will appear in the same way as any removable drive would on 
your computer. 
 Note: Remember, at this point the selected drive has not yet been 
transferred to the host system, it is just visible there. 
5  On the host computer (either directly from Digital iPEPS local console \
or via 
the VNC viewer) locate the new virtual drive (shown as a Removable Dis\
k) 
and copy the files to the required location on the host computer.
 Note: The Remote File or Folder section of this Virtual Media dialogue b\
ox 
provides yet another method of creating a virtual drive from some file\
s or 
folders, as described above.

Resetting the Digital iPEPS to factory default
For situations where the IP address or the password has been forgotten, \
or the 
Digital iPEPS is being reinstalled, it is possible to reset the unit to \
its original 
factory settings. This erases all configuration such as hosts, users a\
nd passwords, 
and restores the default network address.
To perform a factory reset:
1 Disconnect the power, USB and video cables from the Digital iPEPS unit. \
Leave the network cable plugged in and use it to link the Digital iPEPS \
unit 
to a network.
2 Set Configuration Switch 2 to the ON (up) position.
3 Apply power to the unit (either from the power supply or via both USB 
cables).
4 Leave Switch 2 in the ON (up) position until the orange indicator illu\
minates, 
at which point, immediately set Switch 2 to the OFF (down) position.
 If the factory reset is successful, the orange indicator will flash of\
f once after 
fifteen seconds.
 After the factory reset is complete, the unit will reboot and you can co\
nnect 
a VNC viewer to it using the default IP address: 192.168.1.42 to check t\
hat 
the configuration has been reset.
Note: If the factory reset is unsuccessful, power down the Digital iPEPS\
 unit and 
try again.

Appendix 3 - Java viewer options
When you are connecting to 
the	Digital	iPEPS	using	the	Java	
viewer, a number of options are 
available. 
There are four options pages:
Encoding and colour level
Auto select
When ticked, this option will examine the 
speed of your connection to the Digital iPEPS 
and apply the most suitable encoding method. 
This option is suggested for the majority of 
installations.
Preferred encoding
There are three manually selectable encoding 
methods which are accessible when the Auto 
select option is unticked. 
•	ZRLE – This is a highly compressed method that is best suited to slow 
modem connections.
•	Hextile – This method offers better performance than the ZRLE when used 
over a high speed network because there is no need for the Digital iPEPS\
 to 
spend time highly compressing the data.
•	Raw – This is a primitive, uncompressed method that is mainly used for 
technical	support	issues.	You	are	recommended	not	to	use	this	method.	
Colour level
The colour level is fixed at Medium (256 colours) for almost all bro\
wsers.
Inputs
View only (ignore mouse & keyboard)
When ticked, the viewer will not send keyboard 
or mouse information to the Digital iPEPS or 
host computer.
Accept clipboard from server
This feature is restricted to software server 
versions of VNC and has no effect on Digital
