Basic Application
Connect the P-0321 as shown and locate it at the main distribution point in the
house. The output of the P-0321 will send both CATV and the modulator’s
output to the TV location over a single coax cable. Switching between the
CATV and modulator signals is simple: just point the remote at an IR receiver
connected to the coax-based IR system and the IR signal will travel back to the
P-0321 and change it to the desired input.

Connecting the Digital Cable Box to the TV
For best results, use a 2-way RF splitter to feed the RF inputs of the CATV box
and the TV set. Then use RCA cables to connect the audio/video outputs from
the CATV box to the audio/video inputs of the TV.

How to Use the System
To watch the CATV box, select “CATV” on the remote control and then select
the A/V input on the TV.
To watch the modulated channels, select “Modulator” on the remote
control, then select the RF input on the TV and tune to the modulated channel
with the TV remote control.

Using the P-0321 with the E-Series IR Modulators
When connected as shown below, IR signals will pass through the P-0321 and
travel back to the IR emitter outputs on the E4200IR. This allows you to utilize
the built-in IR repeating system to control source components such as satellite
receivers and DVD players.

Systems with Multiple Digital CATV Boxes
To create systems with multiple locations, simply split the output of the
modulator and the CATV feed, then connect the outputs of the splitters to each
P-0321. For larger systems, use splitters with more outputs.

Troubleshooting
If your IR system is not working, check to see if the P-0321 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 using an RF splitter between the modulator and the P-0321 or
between the P-0321 and the IR coax adaptor (IR-4101), check to make
sure you have approximately 8-12 Volts DC on the coax going into the
IR-4101. If there is no voltage at that point, 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-4101. If outputs
from the splitter are connected directly to TV sets without going
through a IR-4101 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.
4. Don’t worry. The IR 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.
