Parts List

  1. 4 feet of flat ribbon cable
  2. DB25 Housing with Grommet, scews and wire holders
  3. DB25 connector
  4. 1.0k resistor X 2 (necessary for Kameleon and other remotes)
  5. 1N5818 schottky diode works for both desktops and laptops
  6. 6 pin female IDC connector to fit your remote (with strain relief)

    Parts List

Let's make it

  1. Familiar with all the components.
    Parts
  2. Put few melted solder into the cup 2, 3, 4, 11, 18 and 25 of the DB25 male connector as shown in picture.

  3. Put few melted solder into the cup 2, 3, 4, 11, 18 and 25 of the DB25 male connector as shown in picture.

  4. Locate two 1K resistors and IN5818 diode. Pay attention to the solid bar on the diode. Cut down two resistors as shown in the photo, also bend the diode into shape to fit between pin 2 and 11 of the male DB25 connector (about 1 inch). Cut the terminals of diode to a proper size as shown in the photo.

  5. Solder two resistors on the pin 3 and 4 of the DB25 connector.

  6. Solder the diode between pin 2 and 11 of the DB25 connector. The solid bar on the diode should be colsest to cup 2. Cut the supplied wire into two pieces. Use one piece to make a connection between pin 25 and 18 of the DB25 connector.

  10. Put the heat shrink tube on line 1 and 2 of the robbin cable.

  11. Solder line 1 and 2 onto resistors. Line 1 is connected to pin 3 of DB25 connector via a resistor. Line 2 is connected to pin 4 of the DB25 connector via a resistor. When soldering, put the heat shrink tube far away form the soldering point, otherwise the tube will shrink

  12. Wait untill soldering points are cold. Pull the heat shrink tube up to the pins to prevent short circuit.
