Connecting The Antenna Rf Signal Cables To A Multiswitch (Latin And North American Systems Only) - KVH Industries TracVision 6 Technical Manual

2.3.6.1 Connecting the Antenna RF Signal
Cables to a Multiswitch (Latin and
North American Systems Only)
Due to the signal polarization of the North American and Latin
American satellites, it is possible for TracVision 6 to support more
than two IRDs aboard a vessel. To install more than two IRD/TV
pairs, an active multiswitch (Channel Master model 6214IFD or
equivalent) is placed between the Antenna Unit and the IRDs.
The following sections provide details for both a single
multiswitch and a multiple multiswitch installation.
Multiswitch Installation for 3-4 IRD/TV Pairs
Figure 2-13 on the following page illustrates typical wiring
arrangements for three or four IRDs. 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 antenna unit's
RF2 plug and 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. Terminate all
unused output connectors with 75 ohm DC blocks
(Channel Master #7184, Radio Shack #15-1259 or
equivalent).
54-0166 Rev. B
Some multiswitches (either active
or passive), such as the Channel
Master model 6214IFD, may
interfere with the 22 KHz tone sent
by DSS Plus™ IRDs to the
antenna. As a result, the antenna
may not receive the signal to
change satellites when you change
channels using your DSS Plus
remote. In this case, you will need
to use the maintenance port
satellite switch procedure explained
in Section 2.5.1, "Installing Your
Selected Satellites."
