E Series Modulators With IR Repeating

The E2200IR PAL & E4200IR PAL are 2 & 4-input RF modulators that
create user selectable TV channels from standard composite video
signals. In addition to creating a whole-house audio video system, these
units also provide an integrated IR repeating system that runs over the
same coax that delivers video to your TV set.

1. Press the Select button until the LED indicator is illuminated for the
input you wish to set. The LED display will show the current channel
setting.

2. Press and hold the Select button until the LED indicator begins to
blink. While it is blinking press the Up or Down button until the desired
channel is shown in the LED display. Press the Select button again to
set then next input to a new channel. If no button is pressed for 2
seconds, the modulator will exit the programming mode.

Note: Do not program the modulator to consecutive channels, this will
cause poor picture quality. Skip at least one channel between your
selections. For example: 39, 41, 43, 45 would be OK.

Helpful Tips:

The use of an RF filter is
recommended for this kind of
setup. It will help remove
unwanted signals from the
antenna feed, allowing the
modulator to perform without
interference. It also helps
provide the isolation needed to
prevent your system from
interfering with your neighbors
TV reception.

Check the signal from your video sources to make sure you have a good
picture before connecting to the modulator. Connect the RF output from
the modulator as shown in the diagram above.

It is important to balance the RF signal levels before joining them together
in the combiner. It may be necessary to amplify the antenna signal to
match it with the high output of the modulator. If the antenna signal is too
low in relation to the modulator, you will notice that the antenna signal is
degraded when the modulator is connected. Simply amplify the antenna
signal to resolve the problem.

From IR

IR-4100

The modulator supports Channel Vision’s IR over coax technology
allowing up to 8 IR-4100 IR coax adaptors to be installed in the system.
Standard IR receivers can be connected so that IR signals are transmitted
back to the modulator where the IR emitters will flash the signals into the
source devices. This enables you to control your source devices even
though they are in a different room.

This IR system places 12Volts DC on the coax. DC passing splitters and
DC blocks must be used as shown in the diagram. DC voltage should
only be allowed to flow to locations that have an IR-4100 installed. If the
system detects a short (or improper connection) it will shut off the IR
voltage until the problem is corrected.

Troubleshooting Video

If your modulated signal looks ‘snowy’ or if you don’t see it at all, follow
these steps to correct the problem.

1. If you are combining the modulator with the an antenna signal (as
shown on pages 4 & 5) disconnect the antenna signal so that the
modulator is the only signal in the system.

a. If this solves the problem, you will either have to change the channel

you are modulating on to a truly empty channel or you will have to filter
out the signals that are interfering with the modulator.

b. If disconnecting the antenna feed does not solve the problem, continue

to step 2.

2. Connect the RF output of the modulator directly to the RF input of a TV
(make sure the signal is not feeding through any unnecessary devices
such as a VCR).

a. If this solves the problem, there is something wrong with your

distribution system. Reconnect your distribution system one component
at a time until you identify which piece is causing the problem.

b. If connecting directly to a single TV did not solve the problem, continue

to step 3.

3. With the modulator still connected directly to the TV, make sure the TV
tuner is set to the same mode as the modulator. TVs can be setup to
work in various TV systems. For example, the frequency assignments
for TV channels in Australia is different than in PAL systems. If the
modulator is in Australia mode and the TV is in PAL mode, the signals
will not be viewable. If the TV and modulator are in the same mode, but
you still can’t see the signal, you may need to perform an auto-program
search with the TV. This is typically an option in the TV’s setup menu.
Before the channel search begins, the TV may prompt you to choose the
type of input signal, choose the option that matched your modulator’s
setting (such as PAL).

a. If auto-programming finds the modulated channel, then reconnect the

system. If you have further problems repeat steps 1 & 2.

b. If auto-programming does not find the channel or if it finds the channel

and there is only a empty black screen, continue to step 4.

4. An empty black screen is usually an indication that there is no signal
getting into the modulator. Verify that an active composite video signal
is connected to the yellow RCA input jack on the modulator. An easy
way to verify the composite video signal is to connect it directly to the
yellow RCA input of a TV set.

a. If you do not have an active video signal, try another source. When

you have verified that the composite video signal is active, reconnect it
to the modulator and repeat step 3.

b. If there was no problem with composite video signal when you

connected it directly to the TV, then call tech support for further
assistance: 1-800-840-0288 or [phone].

Troubleshooting IR

If your IR system is not working, check to see if the modulator’s IR
engine is feeding approximately 12 Volts DC onto the coax between
the shield and center pin. (Any voltage between 8-12VDC is OK). If
there is no voltage between the center pin and shield, check the
connectors on each end of the coax.

If you are trouble shooting a whole-house IR system and you
measure approximately 8-12 Volts DC on the output of the Modulator,
but 0 Volts DC on the output of your RF splitter, check the following
items:

1. Make sure you are using a DC passing splitter. Traditional splitters
will short out DC voltage traveling on the coax and prevent your IR
system from working.

2. Make sure that there are DC blocks (model 3109) on any output
from the RF splitter that will not be connected to an IR-4100. If
outputs from the splitter are connected directly to TV sets without
going through a IR-4100 or DC block, the system voltage will be
shorted out by the input of the TV set.

3. Double check the fittings at the end of your coax cables. If a little
bit of shielding is touching the center pin, the voltage will be
shorted out and the system will not work.

Don’t worry. The IR-4000 engine has a current limiting circuit. If the
engine is shorted (due to a bad connection or a non-DC passing
splitter) nothing will be harmed.
