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.
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.
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.
Check out the UniSketch page to see which types of hardware devices supported in the SDI-GPI Link.
SDI-GPI Link Features
Get the 2x8 GPIO module to add an additional 8 inputs and to get 8 outputs. The SDI-Tally will not have this module, if this option is not selected.
Buy a fully assembled controller ready to work out of the box.
