Skaarhoj SDI-GPI Link Converter, 16 Digital Inputs to Tally Data on the SDI Out Connector

Embed Red/Green Tally Information on SDI signals from GPI Inputs
The SKAARHOJ SDI-GPI Link box will accept 16 digital inputs from your video infrastructure and convert them into Blackmagic Camera Control Tally signals. This will for instance enable any video switcher with tally contact closure outputs to send essential tally information to your supported Blackmagic cameras such as URSA Mini (+Pro) or Studio Camera series.

Camera Support
The Blackmagic 3G-SDI Arduino Shield supports the following formats: 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94 and 1080p60, 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.
