Tuner 1: ASTRA via SCR (1210 MHz)
Tuner 2: ASTRA via SCR (1420 MHz)
Tuner 3: ASTRA via SCR (1680 MHz)
Tuner 4: ASTRA via SCR (2040 MHz)
Tuner 5: Antenna motor 2 switched
through the SPAUN SUR211F#2‘s un-
committed switch #2
To connect to, for example, the satel-
lite at 23.5 east, the correct switching
is:
uncommitted switch #3

(SPAUN SUR420F#2 - input 2)

(without switching)
Tuner 6: All in one: Switching bet-
ween antenna motors and fixed LNBs
via SPAUN SUR211F#1. The antenna
motors are switched in uncommitted
switch #2 and USALS mode.
The fixed LNBs are connected via input
1 (uncommitted switch #1) of the SPAUN
SUR211F#1 and SPAUN SUR420F#1 in
mode 2. It‘s mode 2 because the com-
mand uncommitted switch #2 is always
used by the SPAUN SUR211F#1,with the
uncommitted switch #2 (or US4, 6, 8,
10, 12, 14, 16) it would always switched
to the antenna motor. Mode 2 passes
the uneven US 1, 3, 5, 7 through which
then allows cascading. For example, to
switch to the 4 west satellite, the cor-
rect path would be:
uncommitted switch #1
(SPAUN SUR211F#1 - Input 1)
uncommitted switch #5
(SPAUN SUR420F#1 - Input 3)
committed switch #3
(SPAUN SAR411F#3 – Input 3)
It would also work with this combi-
nation since the SPAUN SUR211F#1 will
switch to Input 1 with all of the uneven
ones:
uncommitted switch #5
(SPAUN SUR211F#1 - Input 1)
uncommitted switch #5
(SPAUN SUR420F#1 - Input 3)
committed switch #3
(SPAUN SAR411F#3 – Input 3)
Note:
the uncommitted switch from
the SPAUN SUR211F and the SUR420F
can also be accessed using an alternate
address:
normal: E0 10 39 Fx
(10 = all Switches)
alternative: E0 18 39 Fx
