To avoid problems with ETX-200 and/or
EPP-100 it is very important that both
DC plugs on the EXM power cord are
inserted into the EPP-100, i.e. each
EXM unit needs to be fed from two DC
outputs at the rear end of EPP-100.
(See picture to the right).
NOTE! Never connect two EPP units to
feed one ETX-200

4.3.5 Service Management
The Service management menu
gives an overview of available
services from antenna input or the
ASI input (if enabled).
Remultiplexing (remuxing) is
possible after downloading a
appropriate SW option. To build
your own MUX you combine
several incoming services. These
can be received either from the
tuner or from the ASI in. Under the
[Digital output] section in this
meny you can see the actual
“Outgoing data rate”. This helps
you to avoid overload for the
output (see page 16 for
information).
English
COFDM mode (SW option)
For [COFDM] (DVB-T) output you
can select Output channel (E2 to
E69) or Frequency and Output
signal attenuation (0 to -31dB).
You can also select bandwidth (6,7
or 8 MHz). For max recommended
output bitrate see page 16.

The DVB standard recommends following Network ID ranges:
DVB-S: 0 to 8191 (0 should be avoided)
DVB-T: 8193 to 13568 (Boxer in Sweden use 8945)
DVB-C: 40961 to 65281 (ComHem in Sweden 41001 and up)
The ETX-200 is designed to perform remultiplexing fully automatically of both audio
and video streams as well as full remultiplexing and regeneration of PSI/SI data.
The advantage for you as a user is much lower risk of failure and the process is
much less time consuming.
In the menu section Available
services all services the unit
receives, both from the [Tuner input]
and from the [ASI input] is listed.
To select the service or services you
want at the [Digital output] mark a
service by clicking the line where the
service is presented and than click
the “Set digital” button. Now an “X”
