Zusammenstöpseln: Zuerst Strom - dann BNC
Ausstecken: Zuerst BNC - dann Strom
Wer genau wissen will wie und warum:
Camera SDI outputs can get damaged when an accessory is connected to the SDI output and is powered through an unshielded cable. All cameras, including all ARRI cameras and other SDI devices, can be affected by this.
This is especially critical for cameras with SDI connections capable of SDI 6G or higher (even if set to work at lower bit rates like SDI 1.5G). Cameras with SDI connections capable of SDI 1.5G or SDI 3G can be protected more efficiently without decreasing the SDI signal quality.
This damage to the SDI connection can occur when connecting an unshielded power cable to an accessory that is already connected to the SDI output of the camera. If the plus pin is contacted before the negative pin, the BNC cable will close the current circuit resulting in the fatal damage of the included SDI driver chip which itself is not designed to handle such high currents.
This problem can also occur when disconnecting an unshielded power cable of an accessory that is still connected to the SDI output of the camera with a BNC cable. Damaged or low-quality BNC cables are more prone to cause this problem.
This problem can occur with all types of power sources including the camera’s accessory power outputs, a power splitting box or an external battery. This problem can also occur when the camera or accessory is in the power on or off state.
