Wake up Cable for Phase One and Credo One-Shot Backs (Minijack Male to Lens Sync)

This is a low-cost simple solution, that allows the Credo to wake up when used in combination with a mechanical lens.

In addition to this, you will require an 8-pin Multi conn. to mini jack adaptor cable for Phase One P, P+, and IQ & MamiyaLeaf Credo 50300144

Phase One Wake-Up Cable is used to manually activate (or "wake up") a digital back’s sensor before taking a photo with a mechanical-shutter camera, such as a technical or large-format camera. 

Primary Purpose
On mechanical camera systems, there is no integrated electronic communication between the lens shutter and the digital back. The digital back's sensor remains "asleep" to prevent heat build-up and digital noise. The wake-up cable provides the necessary signal to prepare the sensor for capture. 

How It Works

• One-Shot Mode: It allows the digital back to operate in "one-shot" mode on mechanical shutters (e.g., Copal).
• Physical Button: The cable features a small button that the photographer presses immediately before firing the shutter.
• Timing: After pressing the button, the sensor stays active for approximately 4–5 seconds. The shutter must be fired within this window, or the capture will be abandoned.
• Hardware Compatibility: It is compatible with Phase One P/P+, IQ1/IQ2/IQ3, and IQ4 series backs, as well as Mamiya Leaf Credo backs.
