DirecTV Approved Indoor / Outdoor 4X4 Multi-Switch

The 4X4 Multi-Switch is sealed so it can be used either indoors or outdoors in
extreme temperature range from -34° to +60° C. When placed outdoors, unused
F connectors on the 4X4 should have weather caps and cable connections
should have weather boots and/or silicone grease.
The 4X4 Multi-Switch, and the LNBs connected to it, is satellite-receiver powered
and draws currents from the receivers directly. It is therefore important to
observe the 100-foot maximum rule (from each receiver to the dish antenna), and
the rule of using a copper-center-conductor RG6 cable, to minimize the DC drop
from each receiver to the dish antenna. This 4X4 Multi-Switch can be used with
Advanced Program Guide (APG) receivers to receive signals from 72.5°W and
95°W satellites. Only APG receivers can see 72.5°W and 95°W satellites.
The 72.5°W satellite transmits both polarities (13V/18V/22KHz) and therefore
both 72.5°W LNB outputs must be connected, as shown in Fig 1. DIRECTV
reserves the right to transmit/change any one or both polarities to a given locallocal area, a the time of installation or at a future date. DIRECTV uses several
downlink horizontal transponders from the 95°W satellite. The horizontal
transponders use 18V/22 KHz polarity and therefore the cable must be
connected to the corresponding connector on the 4X4, as shown in Fig 2.

72.5°W and 95°W LNBs are special market satellites for certain local and ethnic
channels. Some APG receivers may not have signal meters for them in the
receiver setup manuals. Consult your APG receiver manual for details. For such
APG receivers, you should align the 72.5°W dish or the 95°W dish using a signal
meter first, without the APG receiver, before you can connect the multi-switch
and perform an “Auto Config”.
For system setup with either 101°W/72.5°W or 101°W/95°W, if you encounter
error, do a receiver “RESET” selection from the menu screen and repeat “Auto
Config”. If you have several receivers to “Auto Config”, do one at a time to
reduce possibility of error.
For 101°W/95°W reception, one over-sized dish with both LNBs may be used.
Do an “Auto Config” so the APG receiver can get information from the 95°W
satellite. If you are sure 95°W is aligned properly but still getting a very weak
95°W signal, the receiver may have picked up the residual 95°W signal from the
open input port (13V/22KHz). Insert a 10 dB or a 20dB DC-passing, in-line RF
attenuator pad at the receiver’s satellite input and re-do “Auto Config”. But
please remember to remove the pad after the alignment. Pads can be
purchased on line from Pico Macom at www.picomacom.com. Part # series is
