For maximum cable length applications, the input signal should be supplied to the BNC input using a good quality coaxial cable. For shorter cable length applications, the input signal may alternatively be supplied to the RJ45 input using twisted pair cable.

The unit auto-detects which input is connected, and if both are connected it gives priority to the BNC.

The input video format and frame rate are automatically detected, as is HD-VLC compression. The
selected input, speed (3G/HD) and use of HD-VLC are indicated on the status LEDs.

The RS-485 communications to the camera may be controlled via the USB Micro-B control port, or via the
USB-C port which serves as both video output and UVC control input. This selection is made via DIP switch.

The HDMI and SDI outputs are always enabled. The USB-C Video output is enabled when the port is
connected to a host SuperSpeed USB 3.x port. Connection to a host USB2.0 port will display an error.

The SDI output has a separate HD-VLC control, which means the unit can also be used to compress a standard 3G/HD-SDI input video stream.

Any UVC compliant video software can be used to display/record the video.

An example application (with full source code) is available from Active Silicon to demonstrate how to receive, record, display and save image data from the USB Video Class driver. This is part of the Active Silicon Harrier USB Software Development Kit (SDK) that is available in the download section on this product page.

For support on host computers that are running Linux you will need to ensure that you have installed UVC drivers (e.g. V4L drivers) on your Linux system. More information in the BlueBird SDI Adapter datasheet and please consult the documentation for your Linux distribution.

A board-only version of the adapter is available.

Test connector used in manufacturing for circuit verification.

The twisted pair input uses a standard RJ45 connector. This input accepts 3G-SDI, HD-SDI and HD-VLC encoded SDI video streams and is labelled “SDI IN RS-485” on the enclosure.

Connector type: RJ45

See datasheet for pin assignment.

The output BNC is a standard 75 Ohm BNC connector. This provides 3G-SDI, HD-SDI and HD-VLC
encoded SDI data and is labelled “SDI OUT” on the enclosure.

Connector type: 75 Ohm BNC

This connector provides HDMI output for display and is labelled “HDMI OUT” on the enclosure.

Connector type: HDMI Type A

The unit is fitted with four LEDs to provide device status.

See datasheet for the details on function and states of the LEDs.

Compliant with SuperSpeed USB 3.1 (UVC).
