SWITCH CONTROL
•
Normal 22 kHz
(like used on DIRECTV
multi-sat systems)
:
A quick push
of the 22 kHz button provides a 22 kHz tone to the input connector for
controlling 22 kHz switches or universal LNBs. Another quick push of the
button turns off the 22 kHz tone.
•
DiSEqC™
(like used on ECHOSTAR DishPro
and SuperDish
)
:
To
control Eutelsat DiSEqC™ standard compatible switches, push and hold the
22 kHz button for 3 seconds. The Sat Buddy 2™ beeps and the adjacent LED
flashes. With each new press of the button, a new DiSEqC™ command will
be sent and the LED flash rate will change to indicate the LNB or switch
selection made.

Mount the dish and adjust the azimuth, elevation, and skew per the instructions o f the
service provider and hardware manufacturer.
1)
Connect a cable from the Sat Buddy 2’s input connector to the LNB.
2)
Adjust the dish azimuth until signal strength is maximized on the display
or audible tone.
3)
Adjust the dish elevation until signal strength is maximized.
4)
For multi-satellite dishes with LNBs that are controlled by a 22 kHz tone,
press the 22 kHz button to activate the other LNB(s) (refer to SWITCH
CONTROL instructions above). Alternate the alignment and peaking of
each satellite to obtain the best compromise of signal strength between
the satellites.
DIRECTV
™
SINGLE SATELLITE:
Follow DISH ALIGNMENT instructions above.
DIRECTV
™
MULTI-SATELLITE:
Signal received without the 22 kHz tone activated is from the 101º satellite. Signal
received with the 22kHz tone activated is from the 119º/110º satellite signal.
Note:
For North American DIRECTV™ multi-satellite antenna installations, do not
try to obtain the same measurement for each satellite on the Sat Buddy 2’s™ LED
displays. At the time of printing these instructions, there were 16 transponders
measured by the Sat Buddy 2™ from 101º and only 13 transponders from the
119º/110º satellites. We recommend peaking the 101º feed and then bringing the
119º/110º feed to a level where the right bar graph displays about 3 bars less than the
101° feed.
ECHOSTAR DISHPRO™, DP TWIN LNB (110° and 119°):
Connect a cable from the input connector to either side of the LNB head. Press and
hold the 22 kHz button for 3 seconds to enable DiSEqC™ switching. Now, select the
LNB according to the SWITCH CONTROL table on the left of this page.
ECHOSTAR SUPERDISH
™,
three LNBs (DBS 110°/119°, and FSS 105° or
121°):
The Sat Buddy 2™ can power two LNBs and the switch, but not all three LNBs at the
same time. Therefore, it is necessary to work with only two LNBs at the same time.
Connect the two outermost LNBs to the DP34/44™ switch, but initially leave the
middle DBS LNB disconnected. Connect the Sat Buddy 2™ to one of the “TO
RECEIVER” ports on the switch. Perform the following to align the dish:
•
Using the Sat Buddy 2’s™ DISEQC switch, select the switch port connected to
the DBS LNB and align for peak signal. (For information on using the Sat
Buddy’s switch control, see SWITCH CONTROL on page 4 of these instructions)
•
Using the Sat Buddy 2’s™ DISEQC switch, select the switch port connected to
the FSS LNB and align for peak signal.
•
Compare the peak signals between the DBS and FSS LNBs. Compromise the
alignment to obtain peak levels that are approximately balanced (or same level)
between the two LNBs.
•
Disconnect the FSS LNB from the multi-switch and connect the middle (DBS)
LNB. Using the Sat Buddy 2™, select the middle LNB switch port and verify that
adequate signal strength is being received.
ECHOSTAR DISHPRO
™,
two DISH, three DBS LNBs (61.5°, 110° and 119°):
The Sat Buddy 2™ cannot power all three LNBs and the multi-switch at the same
time. Connect the Sat Buddy 2™ between the multi-switch and LNB and align one
dish at a time. Refer to the ECHOSTAR™ application notes above and SWITCH
CONTROL on the left of this page.
