Connecting Three or More IRDs and TVs
To install three or more IRD/TV pairs, an active multiswitch
(Channel Master model 6214IFD or equivalent) is placed between
the Antenna Unit and the IRDs. Figure 2-24 illustrates typical
wiring arrangements for multiple IRDs. If more than four IRDs
are required, contact KVH for additional wiring instructions.
Mount the multiswitch unit in accordance with the
manufacturer’s instruction sheet.
1. Connect the RF cable tagged “RF1” to the
multiswitch input labeled “LNB RHCP +13V”.
2. Connect a second RF cable to the multiswitch
input labeled “LNB LHCP +18V”.
3. Connect the multiswitch outputs to individual IRD
inputs. Use RG-6 cable terminated with
F-type connectors for all RF connections.
4. Terminate all unused output connectors with
75 ohm DC blocks (Channel Master #7184, Radio
Shack #15-1259 or equivalent).

The data cable should be attached
to the master IRD. The master IRD
must remain on for the secondary
IRDs to function properly.
