Security Risk Disclaimer
Pay attention to the following recommendations and measures to increase the level of security of ComAp
products and services.
Please note that possible cyber-attacks cannot be fully avoided by the below mentioned recommendations and
set of measures already performed by ComAp, but by following them the cyber-attacks can be considerably

InteliVision 12Touch & InteliVision 12Touch OEM Global Guide 7
reduced and thereby to reduce the risk of damage. ComAp does not take any responsibility for the actions of
persons responsible for cyber-attacks, nor for any damage caused by the cyber-attack. However, ComAp is
prepared to provide technical support to resolve problems arising from such actions, including but not limited to
restoring settings prior to the cyber-attacks, backing up data, recommending other preventive measures against
any further attacks.
Warning: Some forms of technical support may be provided against payment. There is no legal or factual
entitlement for technical services provided in connection to resolving problems arising from cyber-attack or
other unauthorized accesses to ComAp's Products or Services.
General security recommendations and set of measures
1. AccessCode
• Change the AccessCode BEFORE the device is connected to a network.
• Use a secure AccessCode – ideally a random string of 8 characters containing lowercase, uppercase letters
and digits.
• For each device use a different AccessCode.
2. Password
• Change the password BEFORE the device enters a regular operation.
• Do not leave displays or PC tools unattended if an user, especially administrator, is logged in.
3. Controller Web interface
• The controller web interface at port TCP/80 is based on http, not https, and thus it is intended to be used only
in closed private network infrastructures.
• Avoid exposing the port TCP/80 to the public Internet.
4. MODBUS/TCP
• The MODBUS/TCP protocol (port TCP/502) is an instrumentation protocol designed to exchange data
between locally connected devices like sensors, I/O modules, controllers etc. From it’s nature it does not
contain any kind of security – neither encryption nor authentication. Thus it is intended to be used only in closed
private network infrastructures.
• Avoid exposing the port TCP/502 to the public Internet.
5. SNMP
• The SNMP protocol (port UDP/161) version 1,2 is not encrypted. Thus it is intended to be used only in closed
private network infrastructures.
• Avoid exposing the port UDP/161 to the public Internet.

2.3 Connection to PC
InteliVision 12Touch is connected to the PC using the standard USB A-B cable. Microsoft Active Sync (WinXP)
or Microsoft Windows Mobile Center must be installed on the PC. When the Display Unit is switched on the
connection between the display and PC is established. Windows Mobile Device Center (or Active Sync)
automatically opens the connection dialog window where the information about connected devices can be
found. When the display is correctly connected to the PC then the next programming step using IVProg can be
performed.
Image 2.1 Connection to PC
6back to System overview
2.4 PC tools
2.4.1 IVProg
The InteliVision 12Touch display unit is programmed by the IVProg utility. It can be started from GenConfig PC
tools or directly via menu start in Windows. The IVProg utility is included in the installation suite for a controller
and it is installed automatically. The IVProg utility can also be used for Images and Skins upload into the
InteliVision 12Touch display unit. InteliVision 12Touch comes with the ComAp default Skin. There is no
software available for user skin modifying. User skins must be developed in ComAp. Skins consists of only
sets of colours used in Graphical User Interface, which means, there is no change regarding dimensions or
forms if customized skin is used.
Microsoft ActiveSync (for Windows XP) or Microsoft Windows Mobile Device Center (WMDC; for Windows
Vista, Windows 7 or Windows 10) must be installed on your computer to make IVProg run.
You can download these drivers from Microsoft web page http://www.microsoft.com/. To install these drivers
properly, follow Microsoft instructions.
The IVprog utility supports 64-bit Windows Vista, Windows 7 and Windows 10.

InteliVision 12Touch & InteliVision 12Touch OEM Global Guide 12
Image 2.2 : IVProg Utility
Instructions
IVprog is the utility ensuring programming of the InteliVision 12Touch display unit. When ActiveSync (WinXP)
or Windows Mobile Device Center (WMDC) connection between InteliVision 12Touch and PC is established
using the standard USB A-B cable, the IVProg utility can be started. There are 3 options how to start IVProg.
From the Windows start menu (Start - All Programs - ComAp PC Suite - Tools - IVProg), using menu in
GenConfig Software (File - Firmware Upgrade - InteliVision FW upgrade), or clicking on associated files of *.ivp
package.
For InteliVision 12Touch firmware upgrade, download the latest Firmware (*.ivp package) from ComAp website.
Start the IVProg utility and click on write firmware button. Choose the correct latest ivp file and start the
upgrade. The unit will be programmed.
Note: Firmware can also be upgraded by the display unit own. Menu Administration - Import / Export -
Firmware. Use the *.ivp file (downloadable from ComAp website) for the upgrade.
2.4.2 Image Manager
The ImageManager utility is included in the GenConfig Software. The main purpose of the external pictures is to
allow users modification and build their own Metering screens and use their own pictures, schemes, block
diagrams, etc. to build an impressive view of the application in the Metering screens. The ImageManager utility
is dedicated to the external images managing and building of *.ivi packages. External images (*.ivi packages]
must also be stored in the display for correct function. If there are no External images in the display and even
you can see the external images in GenConfig (Screen Editor) nothing is displayed on the display InteliVision
12Touch.

Image 2.3 Image Manager (part of GenConfig Software)
Note: For more information on how to work with Image Manager (adding of pictures, writing to display) see the
help in GenConfig Software by pressing F1 key.
IMPORTANT: The screen resolution of the Metering screen is 800 x 660 px. It is recommended to
not to exceed this resolution for external pictures.
2.4.3 Screen Editor
InteliVision 12Touch is distributed with the default metering screens. The screens are predefined in each
configuration (archive). The User is able to modify the metering screens if necessary.The default screen
template should cover most of the applications.
The user can easily modify the screens himself by drag&drop using predefined commands and pictures in the
powerful easy to use graphical utility Screen Editor.

5.1 GUI overview
This chapter describes Graphical User Interface (GUI) of the InteliVsion 12Touch display unit. The entire GUI is
touch based meaning there is no physical buttons such as InteliVision 8 or InteliVision 5 display units.
5.1.1 Gestures
InteliVision 12Touch uses gestures for configuring, moving, scrolling, commands and other functions.
Tap
The Tap gesture is the most known gesture. The gesture is defined as click on the touch area. It is a standard
gesture which can be used for clicking on the buttons, areas, cells, etc.
Press and hold
The Press and hold gesture is defined by attaching finger into the touch area and releasing the finger after a time
period. The period is stored in firmware and is not user defined. This gesture can be used e.g. for deleting the
long number in the GUI dialogs.
Pan
The Pan gesture allows the user to move across the GUI. The gesture is done by one finger on the touch area
moving in some direction.
Pinch in or out
The 2 points gesture which allows user zoom in or zoom out. The Gesture can be realized by two fingers moving
in the opposite directions.
Screenshot
This gesture can be called by 2fingers putting each of them into the different corners (left bottom and top right)
of the display unit and smooth move from the actual finger positions. By calling this gesture The screenshot is
made. An actual visible screen is stored on a USB stick if connected. If the USB stick is not connected the
screenshot gesture is ignored.
