# Configuring Dual-Serial Link I/O on Linux Workstations

Smoke supports dual-serial link input and output connections for 4:4:4 clip I/O on Linux® workstations. Configure the type of I/O connection (single- or dual-link serial) using the Input Connection and Output Connection boxes in the Engineering menu. See Setting Video Input and Output Engineering Menu Controls. When you select an input or output connection for clip I/O, you usually also select the colour space conversion method using the Colour Space box on the Engineering menu. The conversion methods that appear in this box depend on the type of I/O connection used. The following table shows the colour space conversion methods that are available for single-link and for dual-link I/O connections on Linux workstations.
