Option 3 - Connecting Three or More IRDs
(European
Systems)
Because the European system comes with a quad-output LNB, all
four RF outputs from the TracVision antenna can be connected to
individual IRDs.
Connecting Three IRDs
To connect a third IRD, a third RF cable must 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.
Connecting Four IRDs
To connect a fourth IRD, use an RF cable 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 2-19 shows an example of a multiswitch
configuration.
