What is the A850 Telemetry Gateway?

What is the A850 Telemetry Gateway?

The A850 Telemetry Gateway is a low-power, battery-backed
device that acts as an interface between an Adcon Telemetry Net­work and one or more hosts running addVANTAGE or similar data
acquisition software. The capabilities of the A850 allow to manage
up to 1000 Adcon RTUs (Remote Telemetry Units), depending on
the version used. In combination with Adcon's Transceiver Module
(Wireless Modem) A440, the A850 constitutes the Base Station of
an Adcon Wireless Telemetry Network.

The A850 Telemetry Gateway provides the following functions to
the user:

• Gateway: the A850 routes data, commands and events
between different physical networks (GSM, POTS, LAN,
Internet, Adcon Radio Network),

• Protocol converter: the A850 translates data and commands
between different protocols (Adcon RTU command line,
addUPI),

• Temporary storage: the A850 provides a short-term data
buffer for actual and historical data,

• Monitor and debugger: the A850 provides monitoring and
debugging capability for the Adcon Radio Network.

CHAPTER 1

15

The data of the RTUs will be automatically acquired, buffered and
forwarded through an Ethernet interface or a modem to one or
more PCs for analysis and further utilization.

Thereby, the remote data acquisition (polling) of RTUs can be
achieved through

• Wireless Modems A440,

• Telephone Modems,

• GSM Modems or

• TCP connections from GPRS Units.

16

CHAPTER 1

Introduction

The forwarding of the data from the A850 to the data assessment
PC is achieved either through

• Ethernet or

• Telephone Modem.

For data communication from and to an A850, private (LAN, VPN)
or public means for data communications (e.g. the Internet) can be
used.

The Gateway is based on a powerful 32 bit ARM processor running
the Linux operating system. It has 256 MB Compact Flash acting as
a hard disk and 64 MB RAM.

The Compact Flash data storage device of the A850 with its capa­city of 256 MB allows to buffer data sampled from 1000 stations for
14 days. The built-in rechargeable battery maintains the function of
the A850 also in case of temporary outages of the primary power
source for up to approximately 24 hours (the achievable time of
operation without mains power depends on the number of RTUs
the Gateway has to poll), preventing any data loss. The central unit
is prepared for future software updates and can be upgraded on
location. The communication with the Wireless Modem A440
mounted e.g. on a roof will be ensured by a serial RS-485 connec­tion. This connection uses a cable which is by default 30 m long
and easy to lay. Upon request, special low-attenuation cables of up
to 90 m can be provided by Adcon.

The A440 Wireless Modem is a low-power, narrow-band data
transceiver operating in the 70 cm band. It implements Adcon's
low-speed radio protocol and is therefore compatible with all
Adcon RTUs. In addition, the A440 modem supports a high-speed
wireless protocol that will be used by future Adcon devices. The
A440 has an 8 bit Flash-based microcontroller and can also be
updated in the field. The A440 is delivered in an IP-65/67 enclo­sure.

case, as first step, you will have to make the new firmware
available in form of an image or on a data storage device on your
local PC and then to upgrade your A850 by transferring the new
firmware from your local PC to your A850 by either uploading the
software, proceeding as described in detail in chapter 2, “Web
Interface”, “Tools”, “Firmware Tools”, “Upload an A850 firmware
image stored as local file” or, alternatively, by downloading the
software from your PC to your A850 as described in chapter 5,
“Configuration”, “Upgrade your A850 Gateway".

17

However, as firmware upgrades may have various impacts on the
function of the upgraded device, we strongly recommend that you
first check on Adcon's web site or by contacting Adcon's technical
support which effects you would have to expect from an upgrade
before you perform it. Depending on the nature of an upgrade,
this documentation may remain valid or may require also changes.
Thus, Adcon cannot be held responsible for possible impacts of
firmware upgrades made without appropriate precautions and
accompanying measures.

Note: for USA: THIS DEVICE COMPLIES WITH PART 15 OF THE

FCC RULES. OPERATION IS SUBJECT TO THE CONDI­TION THAT THIS DEVICE DOES NOT CAUSE HARMFUL
INTERFERENCE.

Introduction

Adcon's Telemetry Network

The A850 represents the link between the various RTUs and the
PC(s) used for evaluating the sensor data and for transmitting con­trol commands, respectively.

.

Figure 1. Schematics of a Remote Telemetry Network

To build a Remote Telemetry Network you need the following:

• one or more Remote Telemetry Units (RTUs) A720, A723,
A731, A732, A733, A733GSM or A740,

CHAPTER 1

Adcon's Telemetry Network

• an A850 Base Station,

• data acquisition and control software, such as Adcon's
addVANTAGE Pro 5 software,

• appropriate means of communications to access your Remote
Telemetry Units, e.g. an Adcon Wireless Modem A440 or
other means of communications, depending on the types of
RTUs you are using. Specifically, if you use the A733GSM, you
either need a telephone line with external modem or an
external GSM modem such as the WorldCom M1206.

Note: For additional information about the RTUs and the addVAN-

TAGE software, consult the respective user manuals.

Introduction

What's new on the A850 ?

The A850 is the successor of the well proven A840 Gateway and
offers the following new features:

• USB device support : USB based devices are supported as
long as they conform to the USB standards for the storage or
communication device classes. The device types that can be
used are

• USB to RS-232 adapters or

• USB modems.

Note: A list of supported devices will be provided with the Firm-

ware release notes. Devices not listed may work, but Adcon
advises not to try as such attempts and possible damage
resulting from it would be at the user’s sole and own risk.

• Multiple modem support: The A850 support more than one
modem. For every modem, the user can configure

• a V110 mode whitelist which tells the A850 for which

phone number the digital V110 mode is supported (V110
mode is supported by most GSM and ISDN networks,
but not by POTS (analog) phone networks),

• whether the modem should answer incoming calls (and

after which number of rings).

Note: A list of supported modems will be provided with the firm-

ware release notes. Devices not listed may work, but Adcon
advises not to try as such attempts and possible damage
resulting from it would be at the user’s sole and own risk.

• Protocol support: The A850 supports encrypted network
protocols, namely

• SSH as replacement for TELNET,

• HTTPS as replacement for HTTP.

Note: The unencrypted protocols is still be supported, however it

is highly recommended not to use them when accessing the
A850 over public (insecure) networks (especially the inter­net).

CHAPTER 1

What's new on the A850 ?

• Users and user permissions: The A850 support up to 100
users with different user permissions:

• one root user which may configure the A850 hardware,

• multiple administrator level users which may configure

the RTU network and give RTU access permissions to
ordinary users,

• multiple ordinary users which may query and configure

only RTUs and sensors for which they have access
permissions.

Note: As default, only the root user is configured.

• Dial-up networking and dynamic IP addresses: To support
A850 devices that do not have an official internet hostname
and IP address, the following features are supported:

• dialling an ISP on given schedule, as callback after

dialling in and/or when notifications must be delivered,

• updating dynamic DNS services, such as DynDNS (this

requires that the A850 gets an official IP address
accessible over the internet after connecting to an ISP. If
the A850 is installed in a private network behind a NAT
router, dynamic DNS is not guaranteed to work),

• hiding the A850 behind an SSH server that is accessible

from the internet (the A850 can be reached through the
SSH server's address).

21

Note: For each of these services, a secondary (backup) connection

may be configured which is used when the primary connec­tion fails.

• RTU routing: The A850 support multiple alternative routes to
an ISM-based RTU. Switching between routes is done by
examining the usage period of the configured routes (if the
usage times of routes overlap, the route with the higher
prority is active).

• Polling:

• The A850 supports multiple polling priorities: all RTUs

with higher priority are served first, then all RTUs with

22

CHAPTER 1

Introduction

lower priorities. The user is responsible for choosing
priorities and polling intervals properly (for example:
configuring a short polling interval and a high priority for
too many stations may result in RTUs of lower priority
never being polled).

• The A850 supports polling multiple RTUs in parallel if
they are reached using different modems or A440
interfaces.

• Statistics and monitoring: The A850 supports A850 and RTU
network statistics:

• load, memory and disk usage of the A850,

• average delay and average radio error rates for the RTUs.

• Sensors: The RF quality, the battery level and the internal
temperature of the RTU as well as the statistical data for
average RTU delay time and average RTU connection quality
may be considered as data from internal sensors of an RTU.
This means that the data representing these parameters can
be used by addVANTAGE like data from normal sensors.

• User interface: All interactions between the user and the A850
(configuration, monitoring, diagnostics, ...) are done by a
JAVA based Graphical User Interface (GUI).

Note: An A440 device connected to an A850 must have firmware

revision 3.0.0 or newer.

 CAUTION The A850 do not support addVANTAGE 3.x software

and the A730MD RTU.

CHAPTER 2

Elements on A850

All three LEDs are on while the device is in reset state or booting
the (Linux) operating system kernel.

The PWR and RUN LEDs are on and the USR LED is off while the
A850 is initialized (the CF card is checked, the configuration is
loaded and various services are started).

The activity LED flashes for 0.1 seconds if there is an RTU com­mand sent or if the answer is received.

The “Error mode” LED pattern is used if there is a serious hard­ware error (unable to read CF card).

The “No configuration mode” LED pattern is used as factory
default (as long as there is no root password configured and no
basic network configuration given).

The “Battery low power” LED pattern is used while shutting down
the Gateway due to low battery.

Installation

Reset Button

The reset button can be reached at the back of the Gateway (by
using a short piece of wire, a paperclip or a ballpoint pen).
Depending on the AC state the Gateway is reset (if AC is present)
or turned off (if no AC is present).

Note: since a reset destroys all configuration changes and mea-

surement data not yet stored in the FLASH, as well as the
system messages, the reset button should be only used as
an emergency measure (i.e. when there is no other way to
reboot the Gateway in a controlled way by using the CLI or
web interface).

Before proceeding with the installation, take a moment to plan
your network. First, in a Wireless (Radio) Network, it is essential to
realize the importance of selecting a good location for the trans­ceiver and, as the admissible distance between the transceiver and
the Gateway is limited, for the complete Base Station. If the A850

CHAPTER 2

Installation

is used in combination with one or several Adcon Wireless
Modem(s) A440, the Base Station configuration will consist in an
indoor unit (the A850) and one (or several) outdoor unit(s), the
A440(s). You must consider several factors, some of them quite
contradictory, when choosing the location:

• From a radio perspective, the height of the receiving antenna
is essential: the higher the antenna, the greater the range of
communication. For the GSM-operated RTUs, this is not an
issue, but you must make sure you have good on-site
coverage from your cellular provider.

• The Base Station should be situated in the same building
where the people managing the Base Station work, or at least
spend some of their time.

27

• Places like cellars, near heat sources, or damp locations are
not suitable.

• Geographically, it is better to have the Base Station in the
center of the area where the RTUs will be installed (this does
not apply to A733GSM stations).

• If you plan to use the Base Station as a server to allow other
people to log in and get data, be sure that a telephone line is
available exclusively for this use.

• Adcon also recommends that you have a telephone
connection next to the PC for when you need technical
support.

The communication distance you can achieve is directly propor­tional to the mounting height of the receiving antenna. The propa­gation of the radio waves used by the Adcon Wireless Modem
corresponds basically to the line of sight. Due to the curvature of

CHAPTER 2

28

System Setup

the earth, on flat terrain, the maximum distance which can be
reached depends on the height above ground of the antennas of
the transceivers of the Base Station and of the measuring stations.
You can't do much on the remote station side, but you have more
options with the Base Station. Some typical examples of distances
achieved under various conditions are shown in Table 1.

The addIT RTU, however, uses low-power technology and was not
designed to communicate over large distances. The typical "line­of-sight" distance an addIT can communicate is 800 m (approxi­mately half a mile). This is valid if the partner device is mounted on
a 3 m mast (9 ft) and the addIT is mounted on a 30 cm mast (1 ft).
The above figures are estimates based on a great deal of experi­ence with installing this kind of equipment and assume a typical
height of 3 m (9 ft) for the antennas of the remote measuring sta­tions. Similarly, ideal physical conditions are assumed for the ter­rain including a flat, open, non-urban environment.

30 m (92 ft) 24 km (15 miles)

Table 1. Communication between Base Station and RTUs A730MD/
A733/A740

Typical distances

achieved

What conclusions can be drawn from Table 1? Primarily, you can
see the importance of having the Base Station antenna as high as
possible. To gain antenna height, you have several options:

• Build a mast directly on the ground; however, a 30 m (100 ft)
mast may not be a practical option.

• Set up a mast on a tall building (of course, it has to be the
building where you want to have the Base Station).

• Install the Base Station in a building that is situated on a hill.

Note: The cable for the outdoor unit delivered with the system is

by default 30 m (about 100 ft) long. If necessary, however,
you can increase the distance between your indoor and your
outdoor unit up to 90 m by using special low-attenuation
cables which can be provided upon request by Adcon.

To use the Telemetry Gateway and Wireless Modem, you need to
do the following:

• Install the outdoor unit.

• Install the indoor unit.

• Initialize the Base Station.

Installing the outdoor unit

Install the outdoor unit (transceiver, “A440 Wireless Modem") on
the rooftop of the house where the Base Station will be located or
on top of a nearby mast. The transceiver has two connectors: one
for a whip antenna (supplied with the A440) and a second that
accommodates the connection cable to the indoor unit.

CHAPTER 2

Installation

29

Note: The installation of the outdoor unit should be performed by

a certified electrician. Make sure that the mast on which the
A440 Wireless Modem will be installed is properly
grounded. Local laws or other regulations may apply.

CHAPTER 2

30

System Setup

Figure 4. Outdoor Unit Installation

Complete the following steps to install the outdoor unit:

1. Fasten the Wireless Modem to the aluminum mast (provided
by Adcon) using the supplied ring clamp.

2. Fasten the antenna to the Wireless Modem.

3. Plug the proper end of the communication cable into the
lower connector of the Wireless Modem.

4. Secure the mast in its place on the roof.

5. Run the cable to the indoor unit.

Note: The cable supplied to connect the outdoor unit to the A850

Telemetry Gateway is 30 m long and cannot be extended,
but special low-attenuation cables with a total length of up
to 90 m can be provided upon request by Adcon.

In addition, if you are upgrading an existing A730SD installation,
you can use the low attenuation coaxial cable provided with the
A730SD’s high gain roof antenna.

 WARNING We highly recommend to only use the low attenuation

RS-485 cables provided by Adcon with a total length of up to 90 m
because attempts to make extensions using other cables could
make your Wireless Modem inoperable, due to the voltage loss on
the additional cable length. Also, damage to the Modem could
result from inappropriate cable impedance.

Installing the indoor unit

The indoor unit is the Telemetry Gateway A850. Connect the
cables to the Gateway as shown in Figure 5.

CHAPTER 2

Installation

31

Figure 5. Indoor Unit Installation

If you are using a hub or switch to connect several computers in a
local area network (LAN), use the twisted-pair Ethernet cable that
Adcon provides to connect the Gateway to the hub. If your com­puter is a standalone PC and is not part of a LAN, you can connect
it directly to the Gateway, as shown in Figure 5, but you will need

CHAPTER 2

32

System Setup

Initialize the Base Station

to provide your own "crossover" network cable, which you can find
in most computer stores. If you plan to use the Base Station as a
standalone unit (that is, without a computer), you need a tele­phone line and an external modem, connected to the A850 either
by USB or to the connector marked “modem”.

Note: Before you operate the Base Station, Adcon strongly recom-

mends that you charge the internal battery to a level where
it can sustain the operation of the Gateway. You can do this
by plugging the power cable into the A850 device while dis­connecting the serial cable from an A440 outdoor unit for at
least six hours.

In order to be able to use your A850 Telemetry Gateway for the
first time, you have to initialize it through its Console Interface by
means of the Terminal emulation program Hyperterm (as, e.g., pro­vided by WINDOWS operating systems as accessory, and also
available for download from the internet). The initialisation encom­passes some basic steps establishing your ownership and disposi­tion of the device. Details are described in chapter 5.

Note: Before initialising the Gateway, the Installation of the indoor

License of the Gateway

The Gateway software can enforce some limitations depending on
a license key:

• the number of RTUs that can be inserted,

• the number of sensors that can be inserted,

• the number of Wireless Modems that can be inserted (with

regard to the planned “multiple A440 support”),

By putting in an additional license key, certain or all restrictions can
be abolished.

Connecting to the GUI

After having completed the preceding chapter, you can start now
to use the Graphical User Interface (GUI) of the configurator of the
A850 which offers advanced support and extremely user-friendly
handling. The connection of a PC to the GUI of the A850 is estab­lished through HTTP/HTTPS via the Web Browser. In order to
enable communication of your PC with the GUI, you first have to
connect the A850 to the PC

• either via LAN connection by means of a network cable which

• or via console connection by means of a serial null modem

Installation

has to be plugged into the LAN connector of the A850

cable which has to be plugged into the console connector of
the A850.

33

Note: If you want to be able to use the GUI via the console of the

A850, you first have to set up a new connection with the role

“Guest”, proceeding as explained in “New Connection Wiz­zard” - ”Setup an advanced connection” - “Connect directly
to another computer”.

Note: THIS DESCRIPTION IS ONLY VALID FOR THE USE OF A PC

WITH WINDOWS OPERATING SYSTEM!

Starting of the Web Browser

Now, start a Web Browser on the PC. A PC running Windows XP as
Operating System has been used as reference to describe the
steps of operation and to produce the following screen shots.

The Browser will be symbolized on the PC by an appropriate Icon:

CHAPTER 2

34

System Setup

Figure 6. Web Browser Icon

The next step to enable the communication between your PC and
the A850 is the input of the IP address in the web browser which
you have settled as the IP address of your A850 in the Console
Command Setup (see Chapter 5).

Figure 7. Web Browser - Entry of IP address

Note: The default IP address for accessing the GUI is

- 192.168.0.1 via the LAN and

- 192.168.1.1 via the console.

Note: For the screen shots in this manual, the IP address

192.168.0.121 was chosen.

The way how to connect the PC via browser to the Gateway
depends now on a detail of the initialization which you made in the
Console Command Setup: if you have generated a HTTPS certifi­cate, you have now to put in https://IP address/ within the Web
Browser, and after the first contact via HTTPS, you have to install
the certificate in your workstation to validate it.

CHAPTER 2

Installation

35

Figure 8. Install Certificate

If you have not generated a HTTPS certificate, you have to put in
http://IP address/in order to initiate the communication.

In any case, the internal Web Page of the A850 will appear.

Note: For security reasons, it is strongly recommended that you

always use an HTTPS connection if you communicate via
internet.

CHAPTER 2

36

System Setup

Figure 9. A850 Web Site via HTTPS with Valid Certificate

As you can see in Fig. 9, a closed keylock appears in the address
line of the browser if you connect your Gateway through a secure
HTTPS link. An open keylock means that the HTTPS certificate has
not been validated. No keylock will be displayed if you use a sim­ple non-encrypted HTTP link.

In order to be able to use the Gateway's configuration utility, you
will need:

• Any computer capable running Sun's Java Virtual Machine

1.5. or newer (or any compatible JVM). For additional details,
please visit Sun's Java web site. You can download from there

CHAPTER 2

Installation

JVMs for popular operating systems as MS Windows, Linux
and Solaris. We strongly recommend the use of the actual
JVM version (1.6 at the date of document release).

• You will also need Sun's Java WebStart installed on your
computer (note: JVM 1.4 and higher includes the WebStart
technology, so you don't have to download/install it
separately). The Java WebStart technology for several
platforms is available from Sun's web site.

• If you can't access this Gateway directly, using a router with
NAT/PAT activated or an SSH tunnel, you need JavaScript
enabled in your browser, else the WebStart application will
not be able to find the Configurator (note: this is the case if
the URL used to get to this page does not match the
Gateway's real hostname and/or port).

If the requirements postulated above are fulfilled, the GUI of the
Configurator can be loaded and opened by clicking the button

37

Figure 10. Start A850 Configurator

The click on this button starts the download of the A850 Configu­rator to your workstation (if it does not yet exist there) and starts it.
While the Configurator is loaded, you will see

Figure 11. Loading A850 Configurator

Note: At the first start of the Configurator, a security warning of

the Java Virtual Machine is issued. Please check the box

“Always trust content from this publisher” if you are sure
that you are connected to your A850. Then, acknowledge
the start of the Configurator by clicking the button “Yes”.

At this point, you have to fill in the User Name and the Password
for logging in. The host is already predefined with the address and
the type of communication, in analogy to the A850 web site.

Note: For security reasons, if you are working via internet, you

should always choose a HTTPS connection for logging into
the Configurator.

CHAPTER 2

Installation

In this application mode, do not click the check box “Off-line” as
this is only for the use of the Configurator on the PC in stand­alone-mode, i.e. without having an A850 connected.

After putting in the proper Login data and clicking the Login but­ton, it will just take a little time until the GUI of the Configurator of
the A850 will appear:

System Setup

Principles of GUI operation

This chapter explains the principles of the GUI operation. A
detailed description of the workflow will be given in Chapter 3.

The main window

The main window of the A850 configuration GUI consists in the fol­lowing components (see Fig. 14):

• A title bar (the header) including the actual release of the A850 as
well as the local IP address which has been set. The IP address rep­resented in the header may differ from the address used as input in
the internet browser: this is the case if the A850 is placed in a LAN
behind an internet gateway (not an Adcon component). Please
contact your Network administator for setting up the internet gate­way.

• A menu bar including the menus to invoke the provided func­tions.

• A tool bar providing shortcut access to specified functions. It is
possible to customize the tool bar; this is helpful because the
defined tool symbols allow quick access to specific functions which
are harder to reach through the “regular” menu structure.

• Tree view providing access to all the objects of the actual config­uration to be configured.

• Table view with a configurable column display to provide suffi­cient information to identify the object to be worked on, depend­ing on the selected node of the tree view.

• Context menus for the nodes of the tree view and the rows of the
table view providing functions to be performed on the underlying
object.

From this main window, the user can start the navigation to either
detailed views of objects or to other windows for issueing special
functions or to the extended search interface for retrieving a lim­ited view of objects.

Fig. 15 shows the header, the menu bar and the tool bar of the
main window of the GUI in detail.

CHAPTER 2

41

FileLogin

If you have worked in the Offline mode (locally on your PC without
communication to an A850), you can always change to the Online
mode by logging in, and then, you can forward the results of your
offline work to your A850 with an “update” command. This means
that you can prepare details of the configuration of your A850 in a
convenient way on your PC away from your A850 which may even
work at the same time in another configuration.

FileLook and feel

“Look and feel” allows you to change the looks of your GUI win­dows. You can select the aspect variant “Windows” which
assumes, automatically, the colors, symbols and other design fea­tures of your PC’s MS WINDOWS display design (as selected by
you individually)

Figure 17. Look and feel: Windows

or the aspect variant “Metal” featuring proprietary colors, symbols

If you have made changes on the settings which have not been
saved in the A850 yet, you will be asked for safety reasons if you
would really like to exit without saving your changes.

43

Edit Commands

EditUndo

Changes made on the last objects representing the configuration
can be revoked by the command “Undo" (each application of the
command “Undo" revokes one change). However, this is only pos­sible as long as you did neither execute a command “Update" or
"Refresh" because the modification state of each object is
recorded until an “Update” or “Refresh” command discards it.)

Figure 20. Undo Menu Item

CHAPTER 2

44

System Setup

EditRedo

If you, after having revoked one or several changes by applying the
command “Undo", have changed your mind and would prefer now
to still make the changes, you can reactivate them again with the
command “Redo"(each "Redo"command reactivates one change).
However, in analogy to "Undo", this is only possible as long as you
did not apply an "Update" or "Refresh" command.

Figure 21. Redo Menu Item

Configuration Commands

ConfigurationRefresh

The “Refresh” command fetches the current configuration from
the A850 Gateway to the PC running the GUI, overwriting configu­ration data used on the PC up to that moment. The user must
answer the question if he wants to discard any changes or cancel
the action. This function is only available using the GUI in the
Online mode.

 WARNING If you select the command “refresh”, all data which

have been put into the GUI will be overwritten by the data from the
A 850.

ConfigurationLockLock Gateway

This command locks the Gateway for other users to perform con­figuration changes.

45

The user is granted a requested lock if no other user has been
locking the Gateway configuration before. A “Lock” granted con­tains a timeout. After this timeout is over, the lock will be released
automatically unless it is renewed explicitly. A configurable
amount of minutes (default 2) before the automatic release time
expires, the user is warned by the GUI by the expiry reminder. This
menu item is disabled (greyed out), when (and as long as) a lock is
held.

If you are using your PC to work on the configuration of the A850
by running the GUI, the current configuration data will be held in
the RAM of your PC (which means that the data are stored in a vol­atile memory and that e.g. an operating system error could cause
loss of these data). By the “Save” command, the current configura­tion data will be stored to the local file system of your PC which will

For RTUs and Wireless Modems, this command allows the user to
initiate radio commands to the respective receiver and effectuates
the responses to be displayed. The user must have the “direct”
access right to the RTU for being able to use this function. Each
command is initiated by sending a “direct” request to the Gate­way. Before issuing the request entered by the user, the GUI pre­fixes it with the ID of the targeted RTU or the Wireless Modem if it
is missing. The protocol of the commands sent and the corre­sponding responses are displayed by a multiline text control, but
can also be exported to a text file and printed. The lines entered
by the user are presented in bold font. The maximum number of
lines available for scrolling is configurable (1000 lines default).

Note: Direct Commands can be used depending on the RTU type

and are described in the respective RTU manuals.

Direct commands can be sent to separate Wireless Modems. To
do this, you first have to select them in “Direct commands”, to
choose the corresponding Wireless Modem in the “Table view”
and to mark it by the mouse before you can send the command.

sent, all RTUs receiving this broadcast will send a feedback. Thus,
sending a broadcast allows to find out which RTUs communicate
actively with the A850 via the connected Wireless Modems.

Tool sSave System State

The “Save System State” function is very useful to debug the A850
if any error or problem occurs. This command opens the interfaces
to specify the data to be stored.

CHAPTER 2

66

System Setup

Figure 58. Save System State Selection

The following data can be selected in the check boxes for saving:
“local logfiles”, “modems configuration”, “last backup file” and
“user settings”. By default, all data are checked for saving.

The local log files of the activities will be stored on the selected
place.

Clicking the button “Estimate file size” allows to estimate the
approximate size of the data file to be saved on the PC.

This function is very important for reporting bugs or other prob­lems back to experts; the stored file allows a deep analysis of the
occurred problem. In case of trouble, before doing anything else,
please use this function! If the available debugging information is
not stored this way, and if a reset is made, it will be impossible to
trace the problem later on.

Main Window views

CHAPTER 2

Principles of GUI operation

The main window of the A850 configuration GUI consists of the
following components:

• Tree view providing access to all the objects to be configured
of the actual configuration,

• Table view with a configurable column display to provide
sufficient information to identify the object to be worked on,
dependent on the selected node of the tree view,

• A menu bar including the menus to invoke the provided
functions,

• A tool bar providing shortcut access to specified functions,

• Context menus for the nodes of the tree view and for the
rows of the table view providing functions to be performed
on the underlying object.

From this main window, the user can start the navigation to either
detailed views of objects or to windows for issuing special func­tions or to the extended search interface for retrieving a limited
view of objects.

73

Tree view

The view in the left part of the main window shows the configura­tion data structured as tree to accelerate the navigation within it.

The nodes of the tree can either be mere structure constructs with­out configuration data (e.g. RTU groups) or objects with configura­tion data and containing multiple child objects (e.g., a RTU with
several sensors connected) or objects without further child objects
(e.g. sensors).

The tree view only contains objects which the actual user is permit­ted to see or to modify.

CHAPTER 2

74

System Setup

Figure 68. Tree view

Table view

The right part of the main window contains a table representation
of data.

The data shown depends on the selection of one or more nodes in
the tree view. The table view is a preview of the objects displayed
to support a quick selection of objects to be worked on.

A table can only contain objects of the same class.

CHAPTER 2

Principles of GUI operation

75

Popup Context Menu

For each object represented as row in the table view or as node in
the tree view, a popup context menu can be activated by clicking
the right mouse button when the object is selected.

In the popup context menu, the commands applicable in each
case to the object or list entry, respectively, are provided.

Thereby, the following commands are always at your disposal:

Figure 69. Table view

Figure 70. Common Popup Context Menu

CHAPTER 2

76

System Setup

Note: If you have the right to carry out changes at the A850, the

command “Edit” is available; otherwise, the command
“View” will be provided instead.

• Menu items “Undo” or “Redo” - initiate the “Undo” or
“Redo” function related to the undoable/redoable actions
with the selected object;

Note: The menu items “Undo” or “Redo” appear in each context

menu, depending on if one or both of these menu items is
or are applicable, respectively (see descriptions for “Edit­Undo” and “Edit-Redo”).

• Menu item “New” - open the detail window of the selected
object to define a new one;

• Menu item “Edit” - open the respective detail window and
display the attributes of the selected object for modification,

• Menu item “View” - open the respective detail window and
display the attributes of the selected object for inspection,

Note: The menu item “Edit” appears only if the user has been

granted appropriate access privileges for modifying the
selected object; otherwise, the menu item “View” will
always appear.

• Menu item “Delete” - delete the selected objects;

• Menu item “Print” - see a print preview of the details of the
selected objects in a formsheet processed for the printer and
start the printout on your default printer,.

Depending additionally from the object to be dealed with, acces­sory menu entries will be listed. As example, the popup context
menu for the object RTU is shown in the following figure:

CHAPTER 2

Principles of GUI operation

77

Detail window

Figure 71. Extended Popup Context Menu for RTUs

For each class of configurable objects, a detail window provides
the detailed view on a specific object. It is used to enter the data
of a newly created object or to change the attributes of an existing
object.

A detail window of a class can be instantiated for each different
object. Trying to open a detail window of an already displayed
object results in activating the window with the selected object.

In each detail window, the buttons described consecutively are
available:

• Print - see a print preview of the details in a formsheet
processed for the printer and start the printout on your
default printer,

• OK - affirmation and acceptance of the entries made in the
respective detail window,

CHAPTER 2

78

System Setup

Note: The OK button is only available if the right to enter or to

modify data has been granted and if data were really
entered or modified, respectively. In order to resume
entered or modified data, respectively, in the A850, the
command “Update” has to be performed consecutively, as
described in “ConfigurationUpdate”,

• Cancel - by “Cancel”, possible entries/modifications having
been made in the respective detail window are discarded, i.e.
the entries/modifications will not be resumed if the button
“Cancel” is clicked.

Debugging tools

For cases where starting the Configurator does not work or is not
desired, you may use the following links to retrieve basic debug­ging information:

• “Download important debugging information to a local file”
allows you in case of possible problems to download the
most important information about the status of your A850 for
problem analysis to your PC and to save it in a local file,

• “Download all debugging information to a local file” allows
you in case of possible problems to download all available
information about the status of your A850 for problem
analysis to your PC and to save it in a local file,

• “View important debugging information” allows you in case
of possible problems to retrieve the most important
information about the status of your A850 and to get it
displayed via your web browser.

Note: In order to be able to use the “Debugging tools”, you have

to login as system administrator (user “root”) or as user
administrator (user “admin”).

85

Configuration tools

For cases where starting the Configurator does not work or is not
desired, you may use the following links to backup and restore the
configuration:

• “Backup the configuration to a local file”: the command
“Backup” allows you to save the data from the A850 locally
on your PC, giving you the opportunity to replay these data
later again into the A850 by the command “Restore” which
allows you to reestablish the state stored by “Backup”(see
ConfigurationBackup);

• “View the configuration in your browser”: view a XML-based
information of the actual configuration of the A850;

• “Restore the configuration from local file”: the command
“Restore” allows you to reload data from the A850 saved by
the command “Backup” on your PC again into the A850 if
you want to reestablish a certain state of the A850 (see
ConfigurationRestore);

CHAPTER 2

86

System Setup

Note: In order to be granted the rights to use the configuration

tools, you must have logged in as system administrator (user
“root”) or as user administrator (user “admin”).

Firmware tools

Firmware tools are provided for your support when performing
firmware upgrades which may become available in the future. As
soon as an upgrade of the firmware will be available, you will be
able to download it from Adcon’s website, following the instruc­tions given there, or by receiving it from your Adcon distributor,
respectively. After having the new firmware available on your local
PC, you will have to transfer it to your A850.

The following firmware tools are provided:

• “List uploaded images in your browser”: view all uploaded
firmware images stored in the flash memory of your A850,

Note: The purpose of this feature is to provide the possibility to

check if all files required for a firmware upgrade have been
uploaded to the A850. This check should be made before
the new firmware is started with “reboot”, after that, the list
of uploaded images will be erased again.

• “Upload an A850 firmware image stored as local file”: load an
actual version of the firmware image in your A850,

Note: Perform an upgrade only if you have problems with your

A850 or if an upgrade is recommended by Adcon, respec­tively.

• “Reboot the Gateway”: after a firmware upgrade has been
prepared, you have to reboot your A850 anew in order to
activate the new firmware.

• “Set Date and Time of the Gateway”: in any case, after a
firmware upgrade, you have to enter date and time anew.

Note: In order to be granted the rights to use the firmware tools,

you must have logged in as system administrator (user
“root”).

Chapter 3. Configuring the Gateway

The configuration of the Gateway summarizes all administrative
settings required for its use and is therefore to be entrusted only
to skilled users qualified as system administrators. According to
this, only the user “root” (the system administrator) has the rights
to make all the settings for configuring the Gateway. As a basic
principle, all other users have only the right to view the settings,
but not to make any changes. The only exception to this rule is
coupled with the point “Users” in the tree window (see below) as
this functionality gives other user groups a limited capability to
make some settings of the configuration. This feature will be
described in detail in chapter 4, “Using the Gateway”.

CHAPTER 3

87

In order to configure the Gateway, you have to proceed as follows:

• Login as system administrator (user “root”) as already
explained in chapter 2, “Connecting to the GUI” (Fig. 13,
“Login”). After the login, the main window of the A850
Configurator (Fig. 14) appears.

• Lock the Gateway by “Lock Gateway” as already explained in
chapter 2, “Commands on the Menu Bar”, Figs. 23 - 25. This
is necessary by reason of the multi-user-capability of the
Gateway, in order to prevent other users from attempting any
conflicting activities while the Gateway is configured.

• Open the “System configuration” in the “Tree view” by
double clicking. Now, the main window of the A850
Configurator as displayed below in Fig. 79 will appear.

The procedure of configuring the Gateway is considerably facili­tated by the user-friendly GUI. As you will notify, the status line of
the window will show the user having logged in as well as the
remaining time the Gateway will stay locked yet.

CHAPTER 3

88

Figure 79. System Configuration List Window

The left part of the system configuration list shows the tree struc­ture (“Tree view”) of the system configuration while the right part
displays the respective corresponding table (“Table view”) of the
marked item. The settings required for configuring the Gateway
are summarized in the tree window in the folder named “System
configuration”. The topmost folder named “Gateway: My Gate­way” contains some basic information about the Gateway itself
which will be discussed at the end of this chapter.

The system configuration list window shows you the items to be
configured as well in its left part as in a “Tree view” as in its right
part in “Table view”.

CHAPTER 3

The system configuration settings encompass:

• PPP (Point-to-Point Protocol) Dialup - management of the PPP
internet connection,

• Dynamic DNS (Domain Name System) - management of your
host name in the DNS to convert host names into affiliated IP
(Internet Protocol) addresses in cases where the IP address is
not static,

• SSH (Secure Shell) Tunnel - management of Secure Shell
Tunnelling to connect terminal devices via internet and by
secure communication,

• Notification Sending - management of the allocation of
recipients for transmissions of messages related to specific
events,

• NTP - management of the Network Time Protocol (a protocol
for time synchronization between computers),

• Dialup Modems - management of dialup modem
communications with their RTUs,

• Wireless Modems - management of Wireless Modem
communications with their RTUs,

• GPRS Modems - management of GPRS modem
communications with their RTUs,

• Users - management of users and user groups as well as of
their respective access rights,

• Operating System - management of operating system
specific assignments,

• Networking - management of the network configuration,

• Gateway Detail - management of Gateway specific
information.

89

PPP Dialup

With PPP Dialup, a network connection to the internet or to a PPP
server, respectively, is established by means of a dialup modem.
The concerned menu allows you to determine the configuration of
a PPP network for a dialup modem connection.

Note: In order to be able to use the PPP network, you have to

enable at least one of your dialup modems for PPP dialup
(“allow PPP dialup”).

CHAPTER 3

90

Configuring the Gateway

The A850 supports two dial-up peer configurations: a primary
which is tried first and a secondary which is only used if the primary
connection can't be established. A secondary configuration is not
required as a matter of principle, but as it enhances the redun­dancy of your network, it is recommended to make use of this
practical feature.

Note: Points which require execution of a login script are not sup-

ported.

Figure 80. PPP Dialup Selection

Via the context menu for PPP Dialup, you can

• lay down the PPP Dialup configuration by “Edit”,

• see a print preview of the selected PPP Dialup configuration in
a formsheet processed for the printer and start the print on
your default printer by “Print item”.

CHAPTER 3

Note: The greyed-out choices “New” and “Delete” are not avail-

able in this context. The choice “Edit” ist only available if
the Gateway is locked while “View” is only available if the
Gateway is unlocked.

Note: Menu items “Undo” or “Redo”: see “Popup Context Menu”

in chapter 2.

Double-clicking the PPP Dialup selected in the “Table view” allows
you to check the selected PPP Dialup configuration.

Note: If not otherwise stated explicitly, the action performed in a

screenshot containing a context menu like the one depicted
in Fig. 80 will always be a click on “Edit”, and the screenshot
displayed as the next will always be the one illustrating the
situation resulting from this action, regardless of any pecu­liar properties of the window appearing next (e.g. replacing
the previous window or just appearing in addition to it as a
“pop-up window”).

91

Note: For being able to use PPP Dialup, it is necessary to make a

PPP Dialup setup on at least one Dialup Modem.

server for the Primary Account:

Figure 88. PPP Configuration - Primary Account

• Phone - enter the phone number provided by your ISP or PPP
serverfor dialup connection;

• Login - enter the account name provided by your ISP or PPP
server for the login;

• Password - enter the password provided by your ISP or PPP
server;

• Max. connect time [s] - allows you to determine the maximum
time a connection to your ISP or PPP server shall be allowed
to persist; if you enter the digit 0, the connection will persist
as long as it will be interrupted either by the defined “Job
scheduling” or by manual termination by the command “Stop
job”;

CHAPTER 3

• Idle timeout [s] - allows you to determine after which period
of inactivity the connection to your ISP or PPP server shall be
terminated;

• IP addr. local - allows you to enter a local IP address for your
PPP connection;

• remote - allows you to enter a remote IP address for your PPP
connection;

• Netmask - requires the masking of the IP address;

Note: If your ISP or PPP server assigns dynamic IP addresses, you

have to enter “0.0.0.0” in the fields “IP addr. local”,
“remote” and “Netmask”.

• Set the default route on PPP connect - if the checkbox is
marked, the opposing communications device is used as a
router when the PPP connection is established.

Secondary Account

97

Figure 89. PPP Configuration - Secondary Account

A secondary account is an alternative account for an internet or
PPP server connection which will be used if no internet connection
comes about through the primary account. The secondary account
can be either an independent access to an ISP or only represent
another dialup phone number for the ISP of the primary account.

Note: A secondary account for an internet connection is a matter

of redundancy and as such, not necessary on principle.

CHAPTER 3

98

Configuring the Gateway

Dynamic DNS

Dynamic DNS (Domain Name System) means that your A850 will
be accessible in the internet by a host name. This is important if
your ISP provides only dynamic IP addresses, i.e. IP addresses
which can always change with each login into the internet.
Dynamic DNS allows you to assign a fixed host name to a dynamic
IP address and to access this address through the host name.

The dynamic DNS updates enables other hosts on the internet to
connect to the A850, as long as the following preconditions are
met:

• If the A850 is directly connected to the ISP, it must get an
official static or dynamic IP address assigned by the ISP;

• If the A850 is acting behind a NAT (Network Address
Translation) router, the NAT router must get an official static
IP address assigned by the ISP;

Note: For cases where the A850 is acting behind a NAT router

which gets a dynamic ISP address assigned by the ISP,
dynamic DNS updates should be supported by and enabled
on the router.

• If there is a transparent firewall between the A850 and the
internet, it must allow certain incoming TCP/IP connection
types (HTTP or HTTPS as a minimum);

• The user must create an account on a supported dynamic
DNS service.

The A850 supports two dynamic DNS update servers: a primary
which is tried first and a secondary which is only used if the primary
connection can't be established. The A850 supports updating its IP
address on a selection of the following dynamic DNS services:

• dyndns, http://www.dyndns.org/

• eurodyndns, http://www.eurodyndns.org/

• hn, http://www.hn.org/

• no-ip, http://www.no-ip.com/

• ods, http://www.ods.org/

• ovh, http://www.ovh.com/

• regsh, http://www.regsh.com/

CHAPTER 3

99

Figure 90. Dynamic DNS Selection

The context menu for Dynamic DNS gives you the following
options:

• “Edit” - to define the Dynamic DNS Update configuration;

• “Print item” - to display the defined Dynamic DNS Update
configuration in a form formatted for the printer which can be
printed from there on your default printer.

Note: The greyed-out choices “New” and “Delete” are not avail-

able in this context.

Note: Menu items “Undo” or “Redo”: see “Popup Context Menu”
