Preventing Damage to SDI Outputs

Issue Summary:

Under certain circumstances it is possible for an SDI connector to incur damage when connected to an accessory and powered without using shielded cables.

Workaround:

RED recommends only using high quality, shielded BNC cables that are rated for 12G-SDI signals and only using shielded power cables for connecting accessories via BNC cable.

Additionally, we recommend following a specific sequence for attaching accessories connected via SDI:

  1. First, connect power to the SDI accessory.
  2. Next, connect the BNC cable to the camera, then accessory.
  3. Lastly, power the camera or accessory on/off.

When detaching an accessory mounted to an SDI output, it is recommended that you follow the following process:

  1. First, shutdown the camera and the SDI accessory.
  2. Next, disconnect the BNC cable from the camera, then accessory.
  3. Lastly, disconnect the power cable from the SDI accessory.
