Connecting Your Camera To A Monitor
Connecting To A Television Receiver
(Tv Set)
If you are planning to use a VCR or similar recording device, then all you need do is plug the RCA jack to the back of such device.
Most portable Tv sets don't come equiped with RCA plugs. You must purchase one of the following RFU modulators at Walmart and
follow the schematics. Please note all RFU modulators will do the job. These are very inexpensive the first example cost me $10 and the
second $7. The last one being small enough that it was incorporated into the project box.
If you use an old tv without a threaded coaxial cable female plug, open up the PL-303 unit and using your soldering iron, remove the
antenna input, then solder two wires, one to the center, the second to the flange, use a few layers of electrical tape on the soldered ends.
Next connect the ends of the two wires to the antenna connections on the back of the tv.
Caution not all RFU units are created equal, even when they come from the same manufacturer. Pelican 7020 has 3 conductors, the red
wire is your ground, the green positive 5 volts, yellow video in. To assemble this cut off the plug (do not cut off the ferrite) and strip off
the insulation, exposing the conductors. drill a hole in your control unit and slip the wire through. secure the cable with a wire tie. solder
the output from the adapter to the red and green wires, next solder the video cable to the yellow conductor. Don't forget to insulate all
solder connections with heat shrink tubing. The powering options above apply to this model.
