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.

 

 

DB25 Connector Configuration
Example of possibilities in the web interface

From the factory the box is configured to control camera IDs 1-8. When input 1-8 is closed to GND, the red tally flag for camera 1-8 respectively will be set on the SDI output from the box. Likewise input 9-16 (on the same DB25 connector) will result in green tally (preview) being set on the SDI output.

 

If you want tally control of camera IDs other than 1-8 or if you want just red tally for camera 1-16 for instance, you simply configure the inputs in the web interface (see picture).

 

The SDI input should be connected to your source for the camera return feed. This would typically be a program output and possibly enriched with CCU data via either an ATEM switcher, the SKAARHOJ RCP, ATEM CCU console or the BlackMagic Arduino Shield. The SDI Tally box passes through all CCU information and only overrides Tally information.

 

Camera Support

The BlacMagic 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.

2x8 GPIO (optional)

As an option you can get a 2x8 GPIO module, to extend GPI to a total of 16+8=24 inputs. Furthermore you get 8 GPO.
