Cascade units

Field of application:
The devices are only suitable for in-house distribution of RF signals! If the
device is used for other purposes, no warranty is given!
With the cascading units 4 SAT IF polarization levels including terrestrial sig-
nals (e.g. FM, DAB+, DVB-T/T2) can be distributed to several SAT receivers.
SPU 556-09 = 6 receivers
SPU 558-09 = 8 receivers
SPU 5512-09 = 12 receivers
SPU 5518-09/-19 = 18 receivers.
Equipotential bonding and Mounting:
To avoid dangerous power surges (e.g. risk of fire and danger of life) the
devices must be connected to the equipotential bonding according to EN
60728-11.
 To connect the outer conductor of the coaxial cable to the equipotential
bonding, use e.g. QEW earthing angles at the subscriber ports of the device.
 Use the included mounting screws and the mounting holes of the device
(6).
RF-Installation:
Note: For a cascading system with the cascade units SPU 556-09, SPU 558-09,
SPU 5512-09 or SPU 5518-09/-19 you need a multiswitch SPU 56-09, 510-09
or 516-09 or a headamplifier SVS 550-09.
 Please note when installing these multiswitches or a headamplifier the
appropriate operation instructions.
 Connect the outputs of the multiswitch to the inputs of the cascade unit.
Use F/F Quickfix adapters CFA 4-01 (not included in delivery). Using adap-
ters you can easily plug the devices on each other (see 1 to 3).
 If you use several cascade units, connect the outputs of the first cascade
unit to the inputs of the next cascade unit and so on. Note: According to
the dimensions of your SAT system, you may have to use after some casca-
de units a further multiswitch to amplify the trunk signals (4).
 Terminate the outputs of the last cascade unit with the resistors CFA 11-00
you find in the carton box of the multiswitch (5).
 Connect the subscriber ports on the left and right sides to the antenna
sockets. Use coaxial cables with F Compression connectors. Suitable cables
and connectors can be found in the current AXING catalogue or under
www.axing.com.
