Hello Flo. To get tally information back to the camera you will need to send Program SDI from the switcher back to the camera. Then the Tally signal must be extracted from the SDI using the Arduino Shield. This would not be a convenient method to do this. The best method is to use the Blackmagic GPI Tally Box and simply run a pair of wires back to each camera. The GPI Tally box is connected Ethernet to the ATEM and will support tally relay contact closure for up to 8 non BMD cameras.
