To install a stand-alone splitter:
• Line up the module’s pins with the grid holes on the
back of the SMC (the module can be mounted hori-
zontally or vertically)
• When set in the desired location, push the pin
plungers to secure the module to the SMC
• Route your RG6 quad-shield coaxial cable into the
SMC, avoiding sharp or abrupt bends in the cable;
install a male F-type connector at the end of each
cable
• A video input (from your cable TV or antenna, for ex-
ample) goes into the center connector (marked IN)
on the splitter
• Attach your cables, those going to each video loca-
tion, to the connectors on the splitter marked OUT
• Cap any unused outputs with a 75-ohm terminator
Installer’s Tip: If you have run extra RG-6 cable
through the home, it is a good idea to spec in enough
splitter capacity and coax to handle an additional two
television locations more than the actual number of
terminations required, in order to allow for future ex-
pansion. If doing so, follow the same rule on any video
splitter and cap all unused F-connectors with Leviton
75-ohm terminators. An uncapped connector can pro-
vide an “open” video circuit that can cause extra noise
to plague the system that can then show up as ghost-
ing on all the TV screens to the house.
Hybrid Video Distribution
The typical cable TV signal coming into a home is usu-
ally sufficient to provide a clear picture to the end de-
vice, such as a television or VCR. In some cases, the
signal might need amplification. There are three things
that affect the signal level in the home:
• The level of the signal from the CATV provider at the
demarcation point
• The number of coax runs (from the splitter, or number
of splits)
• the length of the coaxial cable runs
This is especially likely if the TV sets furthest from the
cable entrance to the home exhibit visible problems
such as “snow”. Leviton’s Video Amplifier is ideal for
correcting this situation and easy to test by simply in-
serting the device into the coaxial video system.
Installer’s Tip: Please read Service Provider
Coordination in Chapter 4 and check with your CATV
provider to determine the signal level at the house de-
marcation point. The input signal level from the CATV
provider or local antenna will be between 0dBmv and
15dBmv. The lower end of that range will require a
video amplifier. At the high end of the range, you might
have sufficient signal to make a video amplifier un-
necessary for up to eight video terminations. Beyond
eight video terminations, you will probably need a
video amplifier.
Active Distribution with the 3x8 Bi-Directional Video
Module
For more sophisticated video distribution subsys-
tems–those involving a combination of cable TV, satel-
lite TV and security video, for example–Leviton’s 3x8
Bi-Directional Video Module is the solution. This mod-
ule features an internal 20dB bi-directional amplifier on
the CATV input plus 2 auxiliary inputs, all routed to an
8-way splitter. The 3x8 Bi-Directional Video Module is
compatable with the advanced, two-way signaling
video technology and saves the installer the trouble of
installing a separate video amplifier and three video
splitters to accomplish the same job and does so at a
cost-effective price.
✍
Take note: The 3x8 Bi-Directional Video Module uses a
dedicated power supply that connects to an F-connectorized
power cord. You should not attempt to substitute any other
cable.
To install the 3x8 Bi-Directional Video Module:
• Align the unit with the mounting holes in the back
panel of the SMC
• Push the pin plungers in, to secure the module
• The internal 8-way splitter outputs connect to as
many as 8 room locations; an essentially unity gain
design uses pre-set amplification so no adjustment is
necessary on the part of the installer
• A map on the front face of the module describes
each output; the cable marked CABLE IN (CI) con-
nects to an incoming cable TV or antenna signal
• Two Auxiliary Inputs (AUX 1&2) connect to the mod-
ulated security cameras and other modulated sorces
such as DVD player
• Two satellite inputs (DIGITAL SATELLITE IN FROM
DISH 1&2) are connected to two digital satellite OUT
TO RECEIVER connectors (1&2) that route the input
from up to two satellite dishes (or single dish with two
LNB’s) to two satellite receivers located at any
wallplate location
• Cap any unused OUT TO TV or AUX IN connections
with 75-ohm termination caps
Active Distribution with the 3x4 Multi-Switch Module
The 3x4 Multi-Switch is a satellite signal distribution
module which routes incoming satellite signals to dual
LNB (Low Noise Block Converters) Digital Satellite
Systems to up to four satellite receivers to rooms
throughout the home.
The receivers automatically determine which signals
and which LNB is appropriate according to the receiv-
er voltage. This module also incorporates a separate
