Features
Universal multi-switch with automatic
operating mode detection. A standard TV or
16 receivers each can be operated in single
cable mode at each connection.
All types of signalling are supported and
automatically detected: 14/18 V 0/22 kHz
(legacy), DiSEqC™ 1.0, single cable stan-
dards according to EN 50494, as well as the
extended command set according to EN
50607 (SCD2 or JESS); PIN codes can also
be used in single cable operation.
Latest IC technology with full band captu-
ring ensures the best signal quality. The
inputs are broadband and can also be
operated with wideband LNBs (e.g. UAS
582). This means that a multi-feed system
can be implemented (for two LNBs, the TV
set must support either DiSEqC™ or the
single-cable standard).
QR code for user instructions
For indoor installation
The integrated AGC (Automatic Gain
Control) ensures that the Sat IF signals
have a constant output level and more
reserve in the distribution.
suitable for DVB-T/T2
When all TV sets/receivers are switched
o, the multi-switch no longer consumes
any power. If Kathrein Power Saving is acti-
vated, the LNBs are also switched o.
The integrated power unit for supplying the
LNB is highly ecient and short-circuit-
proof.
Wideband to Quatro mode:
In this case, the two inputs of the wideband
LNB are permanently connected to the four
outputs of the multi-switch. The outputs of
the EXD 154 behave like a Quatro LNB, so
that an additional standard multi-switch
can be connected.

To prevent the set user band from being used or disturbed by another subscriber, the
user band can be protected by means of a PIN code. The PIN code must be entered in the
settings of the receiver/TV. Each user band is assigned a fixed PIN.

Notes for Single-cable Operation
Only use splitters without diodes (EBC 110 or EBC 114). The required diode
protection is provided by the outlets of the ESU series.
It is especially important to make sure that each user band is assigned only
once, since otherwise the receivers will generate mutual interference. The
frequencies are allocated on the receiver‘s setting menu. Depending on the
type, this assignment may be manual or automatic.
It is recommended to assign the outlets with the shorter length connections
to the higher frequencies. By definition, the system is designed so that single-
cable devices are supplied with 14 V DC.
The power supply is briefly switched to 18 V DC if DiSEqC™ control signals
have to be transmitted. Continuous application of 18 V would block the
system. For this reason, we recommend the use of the ESU series outlets
which are equipped with an electronic switch-o system.
The connected receivers with the single-cable standard EN 50494 can use
user bands 1 – 8. To be able to exploit all user bands, the receiving device
must comply with the new single-cable SCD2 standard according to
EN 50607.
Mode Detection
Mode detection takes place each time the receiver is switched on, separately for each
connection.
The necessary configuration via the rotary switch is reduced to the distinction between
Universal/Wideband LNB and Kathrein Power Saving On/O.
Notes for Standard Operation
If a multi-switch connection is operated with DiSEqC or legacy signalling, this
must be taken into account for signal distribution. In this case, the installa-
tion may not be carried out across several apartments. A simultaneous mixed
operation with single cable devices on one line is not possible; in this opera-
ting mode, outlets of the ESU5x series must be programmed to “Legacy” to
prevent blocking of permanently applied 18 V.

Rotary Switch
The rotary switch is the central element of the multi-switch. It sets the operating modes
and functionalities.
Kathrein Power Saving
As delivered, Kathrein Power Saving is turned o.
NOTE
The settings of the rotary switch are only eective if all subscriber outputs
are powered o.
►Unscrew all connecting cables to interrupt the power supply
Multi-switches without Kathrein Power Saving do not give signalling to the
end multi-switch. For permanent powering of the LNB, the rotary switch must
be set to Power Saving OFF.
Changes in the configuration during operation can lead to undesirable confi-
gurations and malfunction.
►Never alter the configuration during operation
Input Frequency Ranges
Universal
In case of a universal LNB, the four levels (VL, VH, HL, HH) of the LNB are
connected to the inputs of the multi-switch. The LNB supply voltage is
provided at the HL input.
Wideband
A wideband LNB has an extended frequency range (300 to 2350 MHz).
Therefore, only two inputs per satellite are required. In combination with
two wideband LNBs, the multi-switch can operate two satellite positions.
Inputs VL and HL are assigned to position 1, inputs VH and HH to position
2. If only one wideband LNB is connected to the multi-switch, inputs VL
and HL must be used.
In addition, an LNB supply voltage is provided at the HH input in all switch
positions marked in black. Please note that a total supply current of max.
300 mA must not be exceeded.
If only one satellite position is used, all unused inputs must be terminated
with DC-decoupled resistors, e.g. EMK 05.
