SDI

Use SDI to configure the SDI port settings.

WARNING: Under certain circumstances, it is possible for an SDI connector to incur damage when connected to an accessory and powered without using shielded cables. RED recommends only using high quality, shielded BNC cables that are rated for 12G-SDI signals and only using shielded power cables for powering SDI accessories.

Make sure power is connected to the SDI accessory at all times before you connect the BNC to the camera. Ungrounded power from SDI accessories can damage the camera’s SDI port. To avoid this possible damage, attach the power source to the accessory before attaching it to the BNC cable. When using RED Approved Third Party battery plates, unplug BNC prior to hot swapping.

When possible, avoid using P-Tap (also known as D-Tap) cables to power accessories. To avoid damage when using P-Tap/D-Tap, it’s imperative that the connect/disconnect sequence (below) is followed precisely.

BNC Attachment Instructions

When attaching SDI accessories:

Connect a power source to the SDI accessory; power on the SDI accessory.
Ensure a power source is connected to the camera. This ensures both are grounded prior to connecting the BNC. The camera's power state does not have an impact on SDI attachment sequence.
Connect the BNC cable to the accessory, then to the camera.

When detaching an accessory mounted to an SDI output, ensure that you remove the BNC connection to the camera before removing power to the SDI device:

Shutdown the SDI accessory.
Disconnect the BNC cable from camera.
Disconnect the power source from SDI accessory.

When you need to swap out a battery on an accessory mounted to the camera’s SDI port, you must:

Shutdown the SDI accessory.
Disconnect the BNC cable from the camera.
Replace the battery on the SDI accessory.
Connect the BNC cable to the camera.
Power on the SDI accessory.

The SDI port settings you can configure include:

Items	Details
Resolution	Select the SDI port resolution
Frequency	Select the SDI port frequency
Look	Set the look of the playback between RWG / Log3G10 or Image / LUT
Guides	Enable or disable the monitor guides
Tools	Enable or disable the monitor tools
Magnify	Enable or disable monitor magnification
Overlay	Enable or disable the monitor overlay
Overlay Mode	Select the overlay type

Resolution

Use resolution to select one of the following SDI port resolution settings:

• 1080p (default)

• 2K DCI

• 4K UHD

• 4K DCI

The resolution selected here controls the SDI output resolution of the preview page.

Scaling Preview

When monitoring in 1080p or 4K UHD while capturing in a 17:9 format, the entire 17:9 image will be down-scaled to the 16:9 aspect ratio of 1080p or 4K UHD. Small black bars will only appear on the top and bottom of the frame in the monitor path and not on the recorded image.

Frequency

Use Frequency to select one of the following SDI port frequency settings:

• 23.98 Hz (default)

• 29.97 Hz

• 59.94 Hz

Look

You can select the look of the image preview signal sent to the SDI port.

The selections include:

• REDWideGamutRGB / Log3G10

• Image / LUT (default)

Guides

Use Guides to enable or disable (default) the viewing of guides. Tap the switch to toggle between enabled and disabled.

Tools

Use Tools to enable or disable (default) the viewing of tools. Tap the switch to toggle between enabled and disabled.

SDI Port Description

The Serial Digital Interface (SDI) port allows the camera to deliver 12 Gbps of image bandwidth with greater resolution, frame rates, and color fidelity. This single BNC cable solution makes it ideal for the 4Kp60 format.

BNC Attachment Instructions

When attaching SDI accessories:

Connect a power source to the SDI accessory; power on the SDI accessory.
Ensure a power source is connected to the camera. This ensures both are grounded prior to connecting the BNC. The camera's power state does not have an impact on SDI attachment sequence.
Connect the BNC cable to the accessory, then to the camera.

When detaching an accessory mounted to an SDI output, ensure that you remove the BNC connection to the camera before removing power to the SDI device:

Shutdown the SDI accessory.
Disconnect the BNC cable from camera.
Disconnect the power source from SDI accessory.

When you need to swap out a battery on an accessory mounted to the camera’s SDI port, you must:

Shutdown the SDI accessory.
Disconnect the BNC cable from the camera.
Replace the battery on the SDI accessory.
Connect the BNC cable to the camera.
Power on the SDI accessory.
