Preventing Damage to SDI Outputs


Under certain circumstances it is possible for an SDI connector to incur damage when connected to an accessory and powered without using shielded cables. When possible, avoid using P-Tap (also known as D-Tap) cables to power accessories. These cables are not shielded and may damage your camera. 


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 the power source to the SDI accessory.
  2. Next, connect the BNC cable to the camera, then accessory.
  3. Lastly, power the camera and 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 source from the SDI accessory.
