Our 15-foot sync cord runs from the PC outlet on your camera (or flash meter) to the Novatron Power Pack or Monolight. All Novatron products accept the household style male connector. Notice in the photo how each blade on the household side is a different size. If the flash does not fire when you release your camera's shutter try flipping the cord's household side around 180 degrees. This reverses the polarity of the cord and usually solves the problem. Please be real careful with your sync cord. Don't let anyone plug it into a wall outlet. The results could be disastrous.
