# SDI Input Ports

## Overview

ClearView Pivot utilizes DeckLink 8k Pro PCI Express cards for video **inputs**. Depending on the streaming needs, one or more SDI ports are needed. This guide will provide information on which SDI ports should be utilized.

## SDI Port Location

SDI input ports are located at the front facing bottom-left side of the Pivotbox.

There are 2 DeckLink boards. The top one contains the Output ports, while the one at the **bottom** is the **Input board** we are referencing.

## SDI Port Names

DeckLink 8K Pro boards have 5 physical SDI connectors exposed. The first connector, which is located on one edge of the board, at a different distance than the rest is the **Reference in** connector. The other ports are named **SDI 1, SDI 2**, **SDI 3** and **SDI 4** starting from the Reference in connector, as shown below.
