ARGUS 141
1 Introduction
1 Introduction
The ARGUS 141 tests VDSL2 and ADSL. This all-rounder with a color display offers
support for VDSL2 (all profiles) and even ADSL (Annex A, B and M); all integrated into a
single handheld device. Separate chipsets for ADSL and VDSL2 ensure optimum
performance on both interfaces. It also offers extensive statistics functions and evaluates
voice quality in accordance with a variety of techniques, such as using MOS tests (Rfactor).
In addition the ARGUS 141 is also well equipped for checking Internet connections as it
has IP ping, trace route and download tests.
Rounding out the package, the ARGUS can operate in xDSL bridge and PC replacement
mode. In view of the above set of features, it is obvious that the ARGUS 141 offers a wide
range of measurement functions for use on xDSL interfaces. Nonetheless, it should not be
overlooked that this extensive set of features has been packed into an small, handy device;
one that is not only very compact and convenient to use on location – wherever that
location might be – but one that is also ready for use in no time.
Ease of Use
The ARGUS 141 is also extremely easy to use. It has a large (320 x 240 pixel) color display
and it is operated by the use of softkeys and includes a USB client interface. The tester
uses a high-powered, long-life lithium-ion (rechargeable) battery pack.

Software updates can be downloaded to a PC free of charge and then loaded into the
ARGUS at any time. They are available at www.argus.info/en/service.

2 Safety Instructions
2 Safety Instructions
The ARGUS may only be used with the included accessories. Usage of other accessories
may lead to erroneous measurements and may even cause damage to the ARGUS and the
connected installation. The ARGUS is only to be used in accordance with the instructions in
this documentation. Any other usage may result in bodily injury and destruction of the
ARGUS.
-
Before connecting the ARGUS to an access make certain that the voltages on the
access are not high enough to be dangerous or outside the specified range of the
ARGUS or its accessories. You must also taken into account the fact that the
voltage may vary while the ARGUS is connected to the access.
-
Regardless of the interface or access, use the ARGUS only for its intended
purpose.
-
Voltages in excess of 50 V AC or 120 V DC can cause mortal injury.
-
Never attempt a measurement with the case open!
-
The ARGUS is not watertight. Protect the ARGUS from exposure to water!
-
Before replacing the battery pack, disconnect all the test leads and switch the
ARGUS off.
-
Unplug the power supply from the mains, once the ARGUS is switched off and is no
longer in use (for example after recharging the accumulators)!
-
The ARGUS may only be used by trained personnel.
-
In connection with the lithium ion battery pack, please observe the following notes
regarding safety and transport.
Return and environmentally acceptable disposal
The RoHS (EU Directive on the “Restriction of Hazardous Substances”) guidelines, which
restrict the use of certain hazardous substances in electrical and electronic equipment,
apply in eight of the ten categories of the WEEE (EU Directive on “Waste Electrical and
Electronic Equipment”) guidelines. Devices which are in Category 9 “Monitoring and
Control Instruments” are currently excluded from the scope of the Directive. The ARGUS
products fall into Category 9 and are thus not subject to the RoHS guidelines. Nonetheless,
we have voluntarily complied with all of the RoHS guidelines since 1 January 2007.
In compliance with WEEE 2002/96/EU and the German Electrical and Electronic
Equipment Act („ElektroG - Elektro- und Elektronikgesetz“), we began marking our testers
in October 2005 with the following symbol
(
) (DIN EN 50419).
In other words, the ARGUS and its accessories may not be disposed of in the household
waste. Regarding the return of old equipment, please contact our Service department.

Power-Down Mode
Page 125 in battery mode, the ARGUS will automatically power down after it has
been idle for 15 minutes (this setting can be changed, see Page 125). Reasonably
enough, the ARGUS will not power-down during a test (e.g. Loopbox) or when it is
in Trace mode.
As an alternative, it is possible to operate the ARGUS using the included plug-in power
supply. When the power supply is connected, the battery pack is automatically
disconnected. Regardless of the type of supply used, the battery pack should always
installed when you operate the ARGUS. This will ensure among other things the
uninterrupted operation of the real-time clock.
Unplug the power supply from the mains, once the ARGUS is switched off and will
no longer be used (charging the battery pack).

The ARGUS stores all of the settings required to run a test on an ADSL access in profiles.
Up to 10 user-defined profiles can be created. A specific profile can be selected before an
ADSL connection is setup or a test performed, otherwise the ARGUS will use the default
(preset) profile. Only those settings which are relevant will be used for the respective test
situation. The default settings can be restored at any time (see page 126). The procedure
for changing a setting will be illustrated with a single example:

The ARGUS stores all of the settings required to run a test on a VDSL access in profiles.
Up to 10 user-defined profiles can be created. A specific profile can be selected before a
VDSL connection is setup or a test performed, otherwise the ARGUS will use the default
(preset) profile. Only those settings which are relevant will be used for the respective test
situation. The default (factory) settings can be restored at any time (see page 126). The
procedure for changing a setting will be illustrated with a single example:

IP address. If you enter a zero ("0"), the ARGUS will send packets
continuously until the test is stopped manually. Range: 1 to 99999
Default: 10
Pause
This setting determines the amount of time that the ARGUS will wait
between sending test packets. Range: 0.1 to 9.9 seconds
Default: 1 second
Packet size
This setting determines the size of the test packets. By varying the

Fragmentation This parameter sets the fragmentation:
Default setting: on
on
Depending on the network (or router), test packets
may be divided into multiple packets.
off
Fragmentation is not permitted, i.e. the test packets
may be rejected by the network (or router). In this
case, the ARGUS will not receive a packet in reply.
auto
The ARGUS determines the maximum packet size
for the path to the destination address (Path-MTU)
and splits the test packet into smaller packets.
These can then be sent with the minimum of delay
(since the network/router need not fragment the test
packet).

Entry of a name for the profile

If an alias www address is entered as the "Source/Destination" address, the
ARGUS will "only" download the one HTML page during the HTML download
test. The ARGUS does not evaluate the HTML code, so any link to a “true” www
address will be ignored. In this case, the ARGUS will not display an error
message since the “Source/Destination” address specified will have been loaded
without error.
However, since it is not possible to accurately determine the transmission speed
if the duration of the download test is less than 10 seconds, you should download
a reasonably large file (taking into consideration the access speed). 

When entering the “Source” address (server address and download filename)
make certain that you use the correct notation (upper and lower case), otherwise
the ARGUS will report an Error 301 (Moved Permanently) or Error 404 (Not
Found).

If the ARGUS requests multiple downloads, it will reduce the number of
downloads requested to suit the number of downloads supported by the server.
This may result in a deviation from the parameters set. This can be the case e.g.

12 Using the Battery Pack
Changing the battery pack
Switch the ARGUS off and disconnect the plug-in power supply. Afterwards, loosen the
thumbscrew to release the battery pack.
Battery pack handling
The ARGUS may only be operated with the included battery pack. Connecting any
other voltage supply to the battery pack contacts will damage the ARGUS.
-
The supplied battery pack may only be charged in the ARGUS.
-
Do not use the supplied battery pack in other devices.
-
Recharge the battery pack fully at least once a month 
(even if the ARGUS is not used for a longer period of time).
-
If the lithium-ion battery pack is stored, it should first be charged to between 40 and
60 % of its capacity. If the lithium-ion battery pack is stored for a longer period of time,
it should be recharged to this level every six months.
-
Please read the extensive notes on safety and the transport of the lithium-ion battery
pack found in the section "Safety Instructions“.
Automatic recharging of the battery pack when the ARGUS is switched off
The ARGUS automatically recharges the battery pack, if the ARGUS is connected to the
plug-in power supply and is switched off and the battery pack voltage is too low. While
charging, the ARGUS displays the message “Charge battery”. If you press and hold the
power switch, the ARGUS will switch off before the battery pack are recharged. The
ARGUS remains on after fully recharging the battery pack.

Charge battery
The ARGUS will display the current charge of the battery pack graphically, if no power
supply is connected. In the LCD display, a battery symbol will begin to blink, when there is
still approximately (depending on the mode of operation) 5 minutes reserve power. During
this period, it is possible that there may be audible interference and in rare cases even
malfunctions. Connect the power supply.

When the plug-in power supply is connected, the battery pack in the ARGUS can be fully
recharged. It is not necessary to manually discharge the lithium-ion accumulators in the
ARGUS battery pack. It may take up to 6 hours to fully recharge the battery pack.

13 Firmware Update
Important information regarding the ARGUS Firmware Update:
Do not, under any circumstances, start to update the firmware if the ARGUS is
running on its battery pack. First connect the ARGUS to the plug-in power supply,
before sending the firmware update file from your PC to the ARGUS.

An ARGUS USB cable is required to perform an upgrade (USB cable with a miniUSB plug). Save the configuration and test reports before beginning an upgrade. 

Do not disconnect the ARGUS from the PC during the update.

Do not switch the ARGUS off while an update is being performed.

You must also pay attention to the messages on the ARGUS display – not just the
instructions displayed by the Update Tool on the PC.
The update has not been successfully completed until the Update Tool displays a
corresponding message on the PC and the ARGUS – after being automatically
restarted by the Update Tool – shows the normal startup screen.
The ARGUS will not switch on until after you have clicked on one of the two
buttons ("back to step 1" or "Exit program") on the Update Tool after the update
has been completed.
