dates are a clear indication.

In the end, this only proves

the vast amount of technol-

ogy hidden inside the S7000.

The total firmware package

consists of files that update

the following components:

• Bootloader v2.32.12

• Kernel v1.2

• Software


• File System


• CA Module v1.06.1/2.20

In general, meters and re-

ceivers use a so-called boot-

loader to start up. The ac-

tual firmware is stored in the

flash memory and is usually

compressed for reasons of


Firmware Upgrade

1. The starting point was the

firmware with Software Version


2. Upgrade menu of the

Bootloader: connect the

Deviser S7000 to the mains

power supply and turn it on,

while simultaneously pressing

the key with the wrench


3. I attached the USB memory

with the upgrade files into a

root folder called “deviser_

s7000”. Then I selected the F2

key for “USB disk”. This opens

the upgrade options using a

USB memory.

4. The first option “CFE

Upgrade” will update the

Bootloader. This is the only

critical step when upgrading

the Deviser S7000: never

interrupt this! First the memory

banks of the flash memory

containing the Bootloader are


5. Then the new Bootloader is

written into the flash memory.

Once this process, which

takes less than a minute, is

completed the Deviser S7000

will automatically reboot.

6. If you have no USB memory

at hand you can do the upgrade

through a network connection.

For this to work, you need

to setup a TFTP server and

specify its IP address. The real

benefit of this option is the

possibility to remotely upgrade

the firmware: just instruct the

technician to connect the meter

to the network and have him

press the keys on the device.

This allows safe firmware

deployment without actually

distributing it to end users.

7. If everything went OK you

should see the boot logo of

the Deviser S7000. If you look

at the previous pictures, you

will find an option that actually

allows uploading a different

picture: Splash Upgrade. This

is nice to customize the meter.

Imagine you want to put a name

tag on each meters, so that

different technicians don’t mix

up the individually configured


8. Leave the USB memory

attached to the Deviser S7000

and it will directly boot into the

firmware upgrade menu. This

application will scan the USB

memory for upgrade packages.

It takes a few seconds to

process the available upgrade


9. Finally you will be given

the choice to select which

packages you want to install.

You can select the packages

individually or all at once,

pressing the F1 key.

10. At the end of the upgrade

process the Deviser S7000 will

turn itself off. Don’t forget to

detach the USB memory before

turning it on again.

11. After starting again go to

the Setup menu of the Deviser

S7000 to see the current

installed firmware versions

of the different components.

Scroll down to the options page

and you will find the new IPTV

option. This may have been

listed in previous firmware

releases but was not active

due to the beta status. This is

the first software which allows

activation by end users through

a special pin code provided as

a cost option.

12. And here you have it:

my Deviser S7000 is now

prepared for terrestrial TV,

cable TV, satellite TV and IPTV.

A truly complete measuring

instrument for TV technicians

and installers.

13. I selected the option right

away, without any network

cable attached, just to see the

new menus and options.

14. As usual, I tested the

firmware upgrade procedure

exhaustively and I am pleased

to report to our readers, that

you can upgrade or downgrade

the package versions at will,

as sometimes you may need or

prefer to use an older firmware.

You can even select individual

components to upgrade or

downgrade and you can do so

from the automatic upgrade

menu or manually from the

boot loader menu.

efficiency and to save valu-

able resources. By contrast,

the boot loader is not com-

pressed and sits right on

top of everything else. This

makes sure it is run automati-

cally as soon as the device is

turned on. The main task of

a bootloader is to look up the

firmware in the flash memory,

unzip it and copy it into the

RAM memory.

Apart from launching the

firmware, the bootloader is

also required for firmware

updates. During launch, the

bootloader checks whether a

firmware file is available on

an external medium such as

a USB stick, for example. In

to add the feature that is then

activated with a code. If you

decide to unlock IPTV mode

you simply contact Deviser

with the serial number of your

meter to receive the required

activation code.

But first you have to install

the latest firmware release

to get going. For the Deviser

S7000 this update process

requires a little more effort

and time than for most oth-

er meters we have tested so

far. This is because this little

meter is actually a full-scale

computer running the Linux

operating system. Users of

the S7000 generally wouldn’t

know and notice, but for IT

specialists the type of image

files used for firmware up-
