05: Fully Assembled RJ45 P-TTL Cable Extender
Step 5: Close it up
After the conductors have been properly connected, I plugged in my ethernet cable and tested with a multimeter to ensure that only intended connections would pass current and that the resistance would be low. I noticed that Pin 4 on the P-TTL cable was showing high resistance. I had to remove the blue wire from the socket for RJ45 pin 4, manually strip away the insulation, and reattach the wire. Once that was done, I was able to take a test photo using HSS with a camera several feet further from the flash than I would have been able to before.
The completed cable now rests in my light bag.
THIS IS A DANGEROUS PROJECT. IT CAN BREAK YOUR CAMERA, YOUR FLASH, OR BOTH. ATTEMPT IT AT YOUR OWN RISK.
