The Atomos USB-C to Serial Calibration & Control Cable connects an Atomos monitor/recorder like the Atomos Ninja V to the Z CAM E2 4K Cinema Camera and other compatible Z Cam cameras to act as a control cable for the camera. This cable can also be used with the X-Rite i1 Display Pro to calibrate the Atomos monitor. This cable is not compatible with any other X-Rite devices. The cable features a USB Type-C and has a 2.5mm LANC connector on the other end. Almost every Atomos monitor has a matching 2.5mm LANC port.
