3
ohm coaxial cable with F-type connec-
tors.
•
If your TV does not have a VHF 75-ohm
F-connector, you need a 75-ohm-to-300-
ohm matching transformer.
Using AC Power
You can power the modulator using the sup-
plied 15V, 400-mA AC adapter.
Cautions:
You must use a Class 2 power
source that supplies 15V DC
and delivers at least 400 mA.
Its center tip must be set to positive and
its plug must fit the modulator's
12 V DC
jack. The supplied adapter meets these
specifications. Using an adapter that
does not meet these specifications could
damage the modulator or the adapter.
• Always connect the AC adapter to the
modulator before you connect it to AC
power. When you finish, disconnect the
adapter from AC power before you dis-
connect it from the modulator.
Follow these steps to connect the adapter.
1. Connect the adapter’s barrel plug into the
modulator’s
12 V DC
jack.
2. Plug the adapter into an AC outlet.
VCR, DSS Receiver, DVD Player
Connect any audio/video source to the modu-
lator’s
AUDIO IN
L/R
and
VIDEO IN
with an au-
dio/video shielded cable. Make sure
AUDIO IN
L/R
and
VIDEO IN
are connected to corre-
sponding input jacks on the audio/video
source. The modulator is color-coded. Con-
nect the modulator’s
TO TV
to the TV with a
coax cable.
Video Camera Application
Insert the camera’s video cable into
VIDEO IN
on the modulator. Connect the modulator’s
TO
TV
to the TV with RG59 coax cable.
Single TV Application
Connect the modulator’s
TO TV
to the TV with
RG 59 coax cable.
Note: To use the modulator with a cable/an-
tenna system, use the supplied high isolation
A-B switch to eliminate possible interference
with incoming cable/antenna signals.
OPERATION
Selecting the Mode
Press the mode button to display the mode
(
CA
for CATV,
UH
for UHF,
Ir
for IRC, or
Hr
for HRC). To select other modes, hold the but-
ton for about 3 or 4 seconds until the desired
mode appears.
Selecting the Channel
When you have selected the mode, simply
press
Up
or
Down
to select the channel. The
selected channel appears on the display.
Note: When selecting a channel, you must
select a channel that is not being used for
transmission of data (audio/video), and there
must be at least two non-interfering channels
immediately below the selected channel and
at least one non-interfering channel immedi-
ately above it. For example, if you choose
channel 23, you must have two non-interfering
channels below it (channel 21 and 22) and
one non-interfering channel above it (channel
24).
