This module contains ESD components! (ESD = Electrostatic Sensitive Device).
An electrostatic discharge is an electrical current pulse, which can flow also through an electrically
insulated material, when triggered by large voltage difference.
To ensure the reliability of ESD components, it is necessary to consider their most important handling rules:
Electrostatic sensitive components can be processed only on electrostatic protected area (EPA)!
Pay attention permanently to potential equalization (equipotential bonding)!
Use wrist straps, approved footwear for personnel grounding!
Avoid electrostatically chargeable materials such as normal PE, PVC, polystyrene!
Avoid electrostatic fields >100 V/cm!
Use only labeled and defined packing and transportation materials!
Damage caused by faulty connections and / or improper handling are excluded from any
liability.

2. General information
The new models PXU 848 C and PXU 848 T of the compact headend series enable the combined processing of
encrypted and open channels. This allows an easy and cost-effective extension with centrally decoded services for
the community antenna system. Also possible is the use as a free-to-air basic supply in a small boarding house or
hotel, because 40 programmes of 8 transponders are available. The compact headends PXU 848 C/T are used
wherever PAY-TV content and free-to-air channels are to be combined.
3. Description
The compact headends PXU 848 C/T convert the content of eight SAT transponders, terrestrial or cable channels to
either DVB-C or DVB-T. The reception mode can be selected individually at each of the eight inputs: DVB-S/S2,
DVB-T/T2 or DVB-C. Four of the eight channel strips are each provided with a CI interface for decoding encrypted
signals. The integrated multiplex function allows the generation of new output channels with contents of the different
input transponders. For this, the contents of various transponders can be decrypted via one smartcard and thus the
capacities of the smartcards can be optimally utilized. Via the USB interface, the headend can be programmed easily
and quickly. No knowledge regarding the allocation and management of IP addresses is required for this. The
selected settings can be printed, saved and also transferred to other devices via a USB stick. Due to the integrated
LAN connection, remote control of all parameters is possible. The supply voltages can be activated separately for the
SAT and terrestrial inputs with jumpers.

In the PXU 848 C/T, signals are directly fed to the input tuners. Due to the triple tuners, there are eight inputs each
for SAT and eight for terrestrial signals (DVB-T/T2 or DVB-C). In the ‘factory settings’ condition, there is a 12 VDC
voltage for LNB supply on SAT input tuners 1, 2, 5 and 6. This can be switched by corresponding jumpers J1, J2, J4
and J5. On tuners 4 and 8, a 12 V supply voltage for the terrestrial range can be activated by inserting the
corresponding jumpers J3 and J6. The operating states are indicated by external LEDs.
6. Mounting
The compact headend must be mounted in a well-ventilated room. The environmental temperature may not exceed
45 °C. It must be ensured that the air can circulate freely through the ventilation holes, especially in horizontal 19”
mounting. There must be at least 15 cm space around the device ventilation holes, so that the air can circulate
properly. For mounting or when working on the wiring, the power plug must be disconnected.

To insert the CI modules, the covers must be removed. The picture shows the assignment of the CI slots to the
inputs. For wall mounting as shown in the picture, the double ridge guide of the CAMs must always be on the left
side. On the right side, the CAM has only a single guide ridge.
7.1 Pre-programming
The inputs and outputs of the device are pre-programmed ex-works with a standard frequency assignment. A
separate supplementary sheet with the pre-programming is included with the device. In this condition, all input
channels are present at the output. As described above, for reception of the pre-programmed ASTRA transponders,
the SAT inputs must be connected to the LNB in accordance with information on the polarization levels from the
supplement.
7.2 Input level
To ensure perfect reception, make sure that the level at the inputs is between 50 and 80 dBµV.
When receiving digital signals, it is advantageous to have a lower input level rather
than an excessively high one.
If the input level is too high, an attenuator must be used.
7.3 Output level
The output level at delivery is 90 dBµV. This can be changed via device programming. At the TEST socket, an
output level reduced by 20 dB is available.

8.3 Function “Multiplexing“
To optimally utilise the capacities of the smart cards or/and to provide new program selections at the output of the
compact headend, the PXU 848 X offers a multiplexing function. Also certain services within a transponder can be
deleted at the output if they are not desired. Furthermore, encrypted services can be selected for decryption via this
function. If required, an LCN number can be assigned for a program or an SID remapping can be performed.
8.3.1 Multiplexing of services (programs)
Click on the Multiplexing button to open the following window. On the left side of the window, the list of available TV
services from the input is shown and on the right side, the available radio services. In the column IN, the input slot
(input tuner) of the respective program is displayed. At the bottom of the menu, a status indicator documents the
progress while saving the settings. If all data is saved in the system, in the status field Ready will be displayed.
By clicking on the button All OUTPUTS ON/OFF, the assignment of all the services to the outputs can be
deactivated/reactivated or, if necessary specific input transponders only may be reactivated.
The allocation of a service/program is done via a click in the column OUT. A pop up menu will be opened, in which
by selecting the number 1 - 8, the assignment to the corresponding output takes place.
When outputs 1 - 4 are selected, the program can also be decrypted.
The assignment is as follows:
1 = output 1 via CI 1 5 = output 5
2 = output 2 via CI 2 6 = output 6
3 = output 3 via CI 3 7 = output 7
4 = output 4 via CI 4 8 = output 8
18
The lower section of the menu shows the data rate of the respective output.
If the data rate at the output is too high, in the field Rem. Bitrate OUTX, Overflow will be displayed. This means that
the data rate for the set parameters is too high and services have to be removed. The fields Rem. Bitrate OUTX are
marked in colors after checking:
Green: More than 10000 kSym of data rate capacity remaining.
Orange: Fewer than 10000 kSym capacity remaining.
Red: Fewer than 5000 kSym capacity remaining.
Overflow: The data volume for the setted DVB-C or DVB-T parameters are too high.
The verification of the data rate can be activated manually via clicking the button Check.
Press the button Save after finishing assignment of the desired programs to output channels and selection of the
programs to be decrypted. The configuration will be checked for data rate overflow and then saved.
By clicking the column headers LCN, Name, OUT or IN, sorting can be done in ascending order of numbers or
letters.
19
8.3.2 Selection of the channels to be encoded
A precondition of this operation is that the CAM module with corresponding smart card has been inserted into the CI
slot while the headend is in a switched off state. The headend is then switched on and the CAM is recognized and
initialized. The smart card must also beauthorized to decrypt the desired programs. The status is displayed in the
menu Diagnostic. If there is no recognition or if no CAM module is plugged in, a red cross appears in this menu.
If the CAM module with the corresponding smart card is not recognized, no services can be decrypted! The settings
can be done in advance of the installation of CAMs and smart cards .
The selection of the services/programs to be decrypted takes place by placing a check mark in the column CI.
After completing the assignment of the desired programs to the output channels and selecting the programs to be
decrypted, click the Save button. The configuration will be checked for data rate overflow and then saved.
The CAM modules should be only inserted when the headend is in
poweroff mode.
20
8.3.3 LCN function
In the column LCN (Logical channel number), the desired program number can be entered. These programs will
then be sorted in the table in numerical order. Programs which have no LCN assigned, are placed below those
programs that are assigned LCNs.
Precondition is that the TVs/receivers support LCN.
After completing the assignment of the LCN numbers to the desired programs, click the Save button. The
configuration will be checked for data rate overflow and then saved.
21
8.3.4. SID remapping - manual assignment of Service IDs
Based on the feature SID (service ID), remapping of new programs can be performedwithout retuning the connected
receivers. Selected services are assigned with a new SID.
Important: Please ensure that a unique SID is assigned within each transponder to the programs which are
changed.
The maximum number of programs to be remapped must be assigned and scanned at first installation
Changes to lower numbers of programs no new channel search necessary
Changes to higher numbers of programs new channel search is required
Important: If service remapping should be applied, this adjustment has to be done before creating the combined
NIT.
In the column New SID, you can assign a new SID for the desired program. In the column Org. SID the original SID
of the program will be displayed.
The assignment of the service IDs can be carried out continuously across all transponders or continuously within a
transponder. SIDs used in one transponder may be reused within other transponders or if preferred, new SIDs may
be applied to all services.
Example 1 - Allocation of SIDs across all transponders
22
Example 2 - Allocation of SIDs within a transponder enabling reuse in other transponders
SIDs are entered manually. We recommend using hexadecimal values within the range of F001 and FFFE.
Important: The SID can be reused in other transponders (example 1). A service is referenced inside of a
transponder by the unique pairing of ONID/TSID/SID. That’s why the same SID can be used again in
another transponder (example 2). Within one transponder, the same SID may not be used twice.
After completing the assignment of the New SID to the desired programs, click the Save button. The configuration
will be checked for data rate overflow and then saved.
If SIDs have been assigned twice in one transponder, they are highlighted in red in the menu window.
Error correction: Manually change the SID and then press Save.

8.4 Creation of NIT (Network Information Table)
The NIT is a transponder table, which includes informationn for direct reception of digital programs.
The NIT processing requires advanced knowledge of DVB standards!
The combined NIT includes all relevant data of all connected headend devicesand contains information about all
receivable programs in the network.
Important: If possible, place the output channels containing a common NIT on the lowest possible frequencies.
Many receivers begin their search at the lower end of the range and therefore the common NIT is
found as early as possible in the tuning operation. This is particularly relevant if existing systems with
devices from other manufacturers are to be upgraded.
Important: Create a precise system and programming plan before installation/programming.
Important: If service remapping should be applied, this adjustment has to be done before creating the combined
NIT.
Process scheme:
Changes to the NIT table(s) first become effective after closing the PC software.
Please wait approx. 1 min. after closing the PC software until the changes become
effective in all relevant systems.
