Kathrein Power Saving
If an EXD 158 Twin is operated as a stand-alone device or in conjunction with other multi-
switches which bear the Kathrein Power Saving logo, Kathrein Power Saving can be acti-
vated by setting the rotary switch to “ON”. If a receiver is included in the cascade, the LNB
is supplied from the end multi-switch.
NOTE
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 “OFF”.
Only use splitters with no diodes (EBC 110 or EBC 114). The required diode
protection is provided by 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 those outlets with the shorter length connec-
tions to the higher frequencies. By defi nition, the system is designed so
that single-cable devices are supplied with 14 V DC.
The power supply is briefl y 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-off system.
