Building USB JP1 Cable
DiyGadget Part No.: JP1-U01USB JP1 cable version 2.0 - released on 10 June 2004
|
Step 1: Open the package, locate all the components. |
|
Step 2: Locate the IC socket and put it on the PCB. You can bend the pins inward slightly so they line up with the holes on the PCB. |
|
Step 3: Locate three 10K and one 7.5K resistors, and bend them as shown in the picture. |
|
Step 4: Install three 10K resistors on the PCB (R1, R2 and R3). Install one 7.5K resistor on the PCB (R4). |
|
Step 5: Solder all the terminals on the PCB. |
|
Step 6: Cut all terminals 0.1 inch above the PCB. |
|
Step 7: Locate 6MHz ceramic resonator, and 2 capacitors. Pay attention to the positive terminal of the tantalum capacitor. |
|
Step 8: Install ceramic resonator (Y1), monolythic capacitor (C1) and tantalum capacitor (C2) on the PCB. Make sure positive terminl of tantalum capacitor is installed correct. |
|
Step 9: Solder ceramic resonator (Y1), monolythic capacitor (C1) and tantalum capacitor (C2) on the PACB. |
|
Step 10: back side of the PCB after soldering all components. |
|
Step 11: front side of the PCB after soldering all components. |
|
Step 13: Strip off about 0.1 inch of insulations of the ribbon cable. Optional to put some soldering flux one the bare wires, this helps soldering. |
|
Step 14: Pass the wires through the row of 6 "TO REMOTE" holes. Pay attention to pin 4 and 5. They are in reverse order as shown in picture. |
|
Step 15: Soldering the robbin cable on the PCB. |
|
Step 16: Locate the IDC connector. Attach the ribbon cable to the IDC connector. Make sure the wires line up with the notches, then squeeze the two halves together until both retainer loops snap over the ribs and lie falt against the sides. Make sure pin 1 on the PCB is connected to the pin 1 on the IDC connector (identified by an arrow as shown on the picture). See picture for details. |
|
Step 17: Attach the strain relief on the IDC connector as show in picture. |
|
Step 18: Squeeze the strain relief onto the IDC connector. |
|
Step 19: Strip USB cables as shown in picture. Put some soldering flux onto the bare wires to help soldering. |
|
Step 20: Pass the USB cable through the hole of the box. |
|
Step 21: Pass the wires of the USB cable through the row of four enlarged "TO USB" holes on the PCB. Make sure wires pass the correct holes. See picture for details. |
|
Step 22: Make sure everything is correct. Double check all connections, solderings. Make sure no short circuit. |
|
Step 24: Install IC1 into the IC socket. Make sure pin 1 of the IC is connected to pin 1 on the PCB. See picture for details. It's much easier to insert the IC if you bend the pins inward slightly so they line up with the socket holes. |
|
Step 24: Assemble the PCB with the box. |
|
Step 25: Attach the box cover. |
|
