Rotary Switch Modes
There are four different modes that you can
set:
●
A
: 2x 16 UB: 16 user bands per output are
available
●
B
: 1x 24 UB and 1x 8 UB: eight user
bands are available at the top output, 24
user bands at the bottom one
●
C
: 1x 30 UB + Legacy: 30 user bands are
available at the bottom output, the top
output is Legacy (14/18 V – 0/22 kHz),
for receivers without the single-cable
standard
In Mode C, it is important to remember that the bandwidth of the user band is
40 MHz. Possibly, there are satellites with transponders the bandwidth of which is
larger than 40 MHz. These transponders may malfunction or be not receivable.
●
S
(
Static Mode
): In this mode, 27 transponders are translated to fixed output frequen-
cies. These cannot be changed through the receiver. It is possible to connect any
number of receiving devices. It is important to pay attention to the level ratio in the
distribution. DiSEqC supply is not necessary.
Input Frequency Ranges of the Multi-switch
Depending on the connected LNB, there are two 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 – 2350 MHz),
therefore, only two inputs per satellite are necessary. In combination with
two wideband LNBs, the multi-switch can operate two satellite positions.
The VL and HL inputs are assigned to position A, the VH and HH inputs to
position B. If only one wideband LNB is connected to the multi-switch, it is
necessary to use the VL and HL inputs.
In addition, an LNB supply voltage is provided at the HH input in all posi-
tions marked in black.
If only one satellite position is used, it is necessary to terminate all the
inputs which are not in use with DC-decoupled resistors, e.g. EMK 05.
