Extracts iris information from 3G-SDI input signal according to Blackmagic Designs Camera Control Protocol. Outputs analog B4 lens iris control (Hirose- 12), tally LED and relay. Supports camera 1-10 by multi-position switch. SDI input passed through on SDI out. Completely self contained unit - runs independently. Durable enclosure with blue anodized aluminum plates Camera Support The Blackmagic 3G-SDI Arduino Shield supports the following formats using SDI Level B: 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50 (output only), 1080p59.94 (output only) and 1080p60 (output only), but the camera doesn´t have to be running the same video format as the program input, so you can use cameras in Ultra HD while the camera protocol is sent over HD signal to the camera.
