Which version of
the software should I use?
Belkin UK Support site offers two versions of the software
for Windows, version 3.2.19 and version 4.0.2. The 3.2.19
version has proven itself over years as a very solid piece of
software, version 4.0.2 is relatively new, it is the only
version though that has been officially tested for compatibility
with Windows Vista. If you are using Vista, you should use
version 4 of the Bulldog software. If you are using Windows XP
or earlier, there is no reason to update the software. There are
no new features in version 4, on the contrary one of the
features of the software has been dropped: version 4 does not
save open files when the computer is shut down.
Does the software
work on WIndows XP 64-bit and/or Windows Vista
In a word: Yes. Things that do not
work on 64-bit versions of Windows almost always fail because of
lack of 64-bit drivers. The UPS and the Bulldog Software do not
need any drivers, they use the Serial or USB drivers built into
the Operating System. The software will therefore work on 64-bit
Windows without a problem.

seen a few issues recently with use of the software via Remote Desktop,
something that will be more common on Win 2003 than on other Windows
versions. On some occasions the Bulldog icon does not appear in the
taskbar or it appears with a question mark. We have found that despite
of this, the Bulldog service does work and the server will be shut down
in case of a power cut. Furthermore, by following the steps below all
functions of the Monitor software can be used via Remote Desktop.
First make sure that the software is installed with Networking support.
To check this, select Wizard, Master/Slave from the menu. If the option
for Networking Slave is greyed out, the software is installed in Stand
Alone mode. Uninstall and reinstall it with Networking support. When
the install is completed, the Monitor will start and prompt for a new
Make sure that the software works fine locally. As soon as that is the
case, log on via Remote Desktop. Start the Bulldog Monitor via the
Start menu. If the UPS cannot be found (give it a minute or so),
connect to it using View, Remote Hosts. Select the option "Connect to
this IP address" and enter 127.0.0.1 for the address. You should now be
able to view all UPS data. In order to be able to control the UPS and
change the data, select System, Login and enter the password set at
Does the software
work with Mac OS 10.4 and Mac OS 10.5?
Mac computers do not have serial
ports, so you will need to connect the UPS to the computer via
USB. For that reason, of the F6Cxxx models, only the Universal
Series UPS and the Dual Form Factor one can be used on Mac OS.
The Bulldog software works fine on
versions of Mac OS up to OS 10.4. Unfortunately, the software
does not work correctly on Mac OS 10.5, also known as Leopard.
The cause of the problem is that OS 10.5 clears out a data
structure that the software uses to communicate with the UPS.
The solution is to use the UPS support built into OS 10.5
instead of the Belkin Bulldog Software. Just connect the UPS to
your Mac via a USB cable and open the Energy Saver applet in
System Preferences. On the UPS page of the applet, you can
specify which actions are to be taken in the event of power
outages. See the screen shot below for an example.

the PC will be shut down if there is a power problem. The problem does
not occur in earlier versions of the software - the System Tray Icon
was provided by the UPS service itself in these versions.
To fix the problem, a registry edit is need. Locate the folder: HKLM\Software\Microsoft\Windows\CurrentVersion\Run
and edit the key UPS-Status. Change the value to be included in double

Why does the software warn
battery needs replacement?
The Bulldog Software communicates through TCP ports 2710-2714 and UDP
With regard to the TCP port, it would seem that in fact only one of
these ports is used on any one of the machines running the Bulldog
service. Exactly which one is decided at installation time and is
stored in the file PRO_UPS.NET in the Bulldog directory
(/usr/local/bulldog by default on Linux, C:\Program Files\Belkin
Bulldog Plus by default on Windows). The file is a plain text file, the
second line shows the port number.
How do I enable Bulldog to connect
to a UPS on another machine in the network?
If the Bulldog
produces warnings that the UPS battery needs replacement, this may not
necessarily be the case. The software can come up with this message for
#1: It has detected that the battery is actually bad
#2: It thinks the battery is due for replacement.
In the software, go to Configure and click UPS and Property. You'll see
a Last Battery Replacement Date and a Next Battery Replacement Date in
there. The first of the two is set to the current date when the
software is installed. The second is set three years in the future.
These dates will not change if the customer's UPS has been replaced in
the mean time.
If the replacement message occurs after the Next Replacement Date has
passed, first check if the UPS has been replaced in the meantime. If
so, adjust the dates accordingly. If the UPS is indeed three years old,
it is advisable to do a Deep Battery Test to check the condition of the
battery. If it is still OK, change the Next Battery Replacement Date
and set it a year in the future. Typical battery life is about 3 to 5
How do I use the built-in web
The machine to
UPS is connect will be the master, any other machine in the network can
be a slave and receive messages, and be shut down from the master over
Make sure to install Bulldog with the Networking option on both of the
machines. Configure the master to be a master when prompted to do so
when the software first starts or by clicking on the Configure button
and selecting Network, Master/Slave from the menu there.
On the slave, click the Configure button and then go to UPS, Property.
Set the UPS port to Auto. Next go to Network, Master/Slave, select
Slave mode and enter the IP address of the master.
Where does Bulldog keep its log
files and can I safely delete them?
Make sure the
installed in Networking mode and the HTTP files have been
selected to install. Open the Configuration screen via the button in
the toolbar and select Network, HTTP from the menu. The HTTP Root
should point to the WWWRoot directory in the Bulldog one. Optionally
specify a port number different from port 80 if you are
running a service on port 80 on this machine or in the network. Now
connect to the server with any browser. If you have changed the port
number make sure to append it to the URL as in
What is the MUPS programs that
auto-starts with Bulldog?
UPS data to a
log file every minute. These files are used when producing the history
graphs. These files can grow quite large, 2-3 MB per month for
computers running continuously. The files can safely be deleted, but
the historic data is then no longer available of course. The files can
be found in
C:\Program Files\Belkin Bulldog Plus\yyyy
where yyyy is the year. The file names are m.dat, where m is the number
of the month. For example the log file for March 2007 would be:
C:\Program Files\Belkin Bulldog Plus\2007\3.dat
Why does the battery level drop so fast when I run a test or there is a power cut?
MUPS.EXE is a
to send e-mail notifications through the Microsoft Mail API (MAPI). If
you do not use e-mail notifications or if you use them via SMTP it is
safe not to start MUPS.
The battery level as
reported by the software is based on the battery voltage. UPS batteries
are all 12V, sometimes to or three of them are used in a series to
produce 24 or 36V. When the UPS is on mains, the battery is under
continuous "trickle charge" as a result of which the actual voltage will
be higher than the battery rating voltage, most of the times around
13.7V, 27V or 41V respectively. This voltage is selected as the 100%
mark for the battery level meter.
When the UPS goes to battery, the voltage immediately drops to the
rating voltage of 12, 24, or 36V because the battery is no longer
charged. This causes the sudden drop in the battery level meter,
sometimes to 75%. From that point onwards, the level should go down
further slowly and gradually.

Where do the documents go that are
auto-saved when the machine is shut down?
Documents that had a file name already, i.e. that had been
saved before will be saved with their original names in
their original locations. New documents that did not have a
file name are saved in
C:\Windows\Temp with a name starting off with UPS. When
the Bulldog software is next started, it will pop up a
window showing all files that have been auto-saved with a
Please be aware that dependent on the Windows
version and installation you may need administrative
privileges to access the C:\Windows\Temp folder.
Please be aware that the auto-save feature has been
dropped from the current version 4 (4.0.2) of the software.
