Wiring 3+ Receivers

A
To connect three or more receivers to a circular
system, follow these steps to install an Eagle
Aspen multiswitch (KVH part #72-0310) between
the grounding block and the receivers, as shown
in Figure 35.
1. Connect an RF cable from the "RF1"
connector on the grounding block to the
"13V" connector on the multiswitch.
2. Connect an RF cable from the "RF2"
connector on the grounding block to the
"18V" connector on the multiswitch.
3. Connect the receivers to the individual
outputs of the multiswitch.
4. Connect the receivers to the customer's TVs.
The use of a multiswitch interrupts satellite
switching communications between the receiver
and antenna. As a result, you will need to use one
of the following methods for satellite switching:
Automatic Switching for
DIRECTV Ku-band Tri-Sat:
To switch automatically
between three satellites using
a DIRECTV H21-200 or
H20-600 receiver, you will
need to install the KVH
Tri-Sat AutoSwitch Kit (KVH part #72-0301-07).
Manual Switching (Dual-Sat):
To manually switch between your
two selected satellites, you can use
the TV/SAT Switch (KVH part
#01-0245). With the TV/SAT Switch
installed, you can switch between
satellites at the press of a single
button.
Manual Switching (Tri-Sat or Dual-Sat):
To manually switch between two or three
selected satellites, you can use a PC connected to
the switchplate's Maintenance port. See the
User's Guide for details.
