test center.
5) In the Decoder Settings
menu you can freely select
the video and audio formats,
with a huge array of options
We restricted ourselves
to perform a tuner search
and then selected ARD HD.
This meant that ARD HD
would be available from the
video and audio outputs of
happy about that, since it is
labelled Alarm.
In step 4 just above we
had activated Multiplex,
which meant we needed to
define which channels from
the three inputs should be
taken over.
As mentioned in the begin-
ning, the NDS3975 can also
be set up with great ease
using the Network Manage-
ment Software (NMS) right
on the PC. For the Multiplex
setup we opted for that very
convenient option.
The software is not de-
signed specifically for the
NDS3975 but works with all
Dexing products. This way
a head-end equipped with
different Dexing products
can be set up and controlled
with a single software solu-
The tree structure of the
software allows defining
1. All Dexing devices are supported by the
NetworkManagement Software, allowing entire head-end
stations to be managed with a single software solution.

also the channel that would
be displayed on the mini
screen on the front panel.
Any channel can be se-
lected for output, no matter
whether it’s in the trans-
port stream of the tuner or
comes for the ASI or IP in-
6) We did not change
the network configura-
tion, since the pre-defined
IP address of the NDS3975
( worked bril-
liantly for our test network.
As soon as a single change
of the NDS3975 parameters
is confirmed the IRD be-
comes active. You can see
this with all five LEDs light-
ing up: Power, Tuner Lock,
ASI Lock, IP Lock and De-
coder OK.
Only one LED remained
dark, and we were quite
groups which can be used to
control several head-ends at
the same time, for example.
Each group can then be set
up to manage any number of
Dexing devices.
The one thing you need
to make sure is to select
the correct device from the
drop-down list, so that the
corresponding tabs show
the menu options for that
particular device.
