Make a Simple Nonbuffered JTAG Cable
- Simple JTAG Schematic
- Familiar with all the components.
- Put some melted solder into the cup 2, 3, 4, 5, 13, and 18 to 25 of the DB25 male connector as shown in picture.
- Cut the rest resistors as shown in picture.
- Use the cutted resistor conductor to connect 18-25 pin together.
- Solder 5 resistors onto the DB25 connector (pin 2,3,4,5 and 13).
- Cut the resistor conductors as shown in picture and put some melted solder onto the bare conductors.
- (10 pin configuration) Cut and strip the flat cable as shown, put some melted solder onto the bare wires, then put the heat shrink tube onto the wires.

- (20 pin configuration) Cut and strip the flat cable as shown, put some melted solder onto the bare wires, then put the heat shrink tube onto the wires.
- (10 pin configuration) Solder flat cable onto the DB25 connector as shown in picture.
- (20 pin configuration) Solder flat cable onto the DB25 connector as shown in picture.
- (10 pin configuration) Put heat shrink tubes onto the resistors to prevent short circuit.
- (20 pin configuration) Put heat shrink tubes onto the resistors to prevent short circuit.
- Align wires on the IDC connector. Make sure line 1 is under the little triangle as shown in the picture. Then squeeze two halves of the IDC connector together until both retainer loops snap over the ribs and lie flat against the sides.
- Put the strain relief onto the IDC connector. Squeeze the strain relief and the IDC connector.
- Prepare the DB25 shell as shown in picture.
- Take the two wire holders and clamp them onto the cable. Pay attention to red arrow in the picture.
- Put the DB25 connector into one half of the DB shell.
- Close up the DB25 shell. Use the remaining two screws and nuts to finish the assembling.
