5-Pin DIN Plug (Radio Shack Cat
Set of RCA type connectors (one for video and one for audio)
Solder (use a fine electronics grade solder, NOT the plumbers type)
Soldering iron (30W seems to work well for me)
Diagonal cutting pliers
Ohm Meter (for testing the cable)
Some type of clamping device (to hold the plug still while you solder it)
Cut the RCA connectors off of one end of the RCA cable. This
will expose the wires for us to work with and leave a set of RCA
connectors on the opposite end.
2. Strip 1/2 inch of the outer casing away, exposing the center conductor surrounded by the grounding conductors.
3. Cut away about half of the grounding conductors so as to decrease their quantity and enable us to fit them in the DIN plug.
4. Strip away about 1/4 inch of the insulation on the center conductor.
5. Repeat steps 2 to 4 on the other cable.
6. Tin the center conductors of both cables (apply a thin covering of solder to the. This will make it easier to join the conductors to the plug.
7. Twist the ground wires from both cables together and tin them also.
8. You should have three wires to work with, a ground and two center conductors.
9. Cut the tips of all the wires to make a clean and even connection.
CONNECTING THE WIRES:
You must use caution when applying heat to the pins as the plastic holding the pin will melt if it gets too hot.
1. Apply a small amount of
solder to the inside of pins 2, 3, and 4.
2. Heat pin-3 until the solder melts and insert one of the center conductors, remove the soldering iron and allow to cool.
3. Repeat step 2 for pin 4
4. When connecting to pin 2, you will use the ground wire not the center conductor
Pin-2: Ground Connection
Pin-3: Audio Connection
Pin-4: Video Connection
TESTING THE CONNECTIONS:
1. Use an Ohm meter to test the
continuity between the pin and the other end of the cable. If you do
not get a reading, then one of the connections is bad. Check the
connection and reapply solder if needed.
2. The things to check for are that you have continuity between the grounds on both RCA cables and pin-2 and that the center conductors have continuity from pins 3 and 4 to the respective RCA pins. You also want to ensure that none of the pins are shorting to any other pin.
