Other Information

The Harrier SDI Adapter is designed for format conversion of 3G-SDI, HD-SDI and HD-VLC video streams and operates as a USB/HDMI/SDI converter and external frame grabber for video streaming and video capture.

The video input signal is supplied via the BNC connector, or via the Ethernet (RJ45) connector. Three simultaneous video output formats are supported: 3G-SDI/HD-SDI or HD-VLC (via BNC), HDMI (via standard HDMI connector), and SuperSpeed USB/USB Video Class (UVC) v1.1 output (via USB Type-C cable). A remote camera connected by RS-485 may be controlled via the USB Type-C port (using the Harrier USB SDK or a UVC application), or via the separate USB-UART (USB Micro-B connector) interface. The RJ45 connector includes RS-485 camera control signals, camera power supply and HD-VLC compressed video input (over twisted-pair).

As well as standard 3G / HD-SDI streams, the Harrier SDI Adapter automatically decodes HD-VLC encoded video streams, these can be delivered by our 3G-SDI/HD-SDI AF-Zoom Block Camera with Tamron MP1110M or our 3G-SDI/HD-SDI AF-Zoom Block Camera with Sony EV7520A. Compared to 3G-SDI co-axial cable based solutions this end-to-end HD-VLC solution enables the use of longer cable lengths (see Active Silicon’s White Paper on long-reach HD digital video solutions with this technology).

The unit is available as a standalone board (as in product image above), or mounted in a rugged enclosure for use with a PC or laptop.

Watch our Harrier product video to find out more about HD-VLC based long reach cable solutions.

General information

Power Options

In both the board only and the enclosed versions, the unit may be bus powered from either USB port. The board version also has a power header for a fixed system power supply. If multiple power sources are connected, an internal power switch selects the appropriate source with the following priority:

1. System power header.
2. USB 3.0 type C port.
3. USB 2.0 Micro-B port.

Application Information

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.

Supported Video Formats

The Harrier SDI adapter supports a range of video input/output formats.
The SDI input and output are compliant with ST292 (HD-SDI) and ST424 (3G-SDI). The HDMI output complies with v1.4 of the HDMI specification. The USB video is UVC 1.1, USB 3.1 Gen 1 Super Speed, 5 Gbps.
