Option 3 - Connecting Three or More IRDs
(European Quad-output LNB Systems)
In European systems that come with a quad-output LNB, all four
RF outputs from the TracVision antenna can be connected to
individual IRDs.
Connecting Three or Four IRDs
To connect a third IRD, a third RF cable should already be
connected to the plug labeled "RF3" on the base of the TracVision
antenna. Connect the other end of the RF3 cable to the plug
labeled "LNB," "ANT/SAT," or "SATELLITE IN" on the third
IRD. To connect a fourth IRD, use the fourth RF cable, which
should already be connected to the plug labeled "RF4" on the
base of the antenna.
Connecting More than Four IRDs
To connect more than four IRDs, you will need to install an active
multiswitch between the antenna and the IRDs. Connect the
multiswitch unit in accordance with the manufacturer's
instructions. Figure 2-11 shows an example of a European
multiswitch configuration.
