Thanks for your response.
I want to use this for camera touchdown/preview, using a Sony RCP 750 which offers contact closure GPI.
I’m hoping I can take the GPI out of the RCP, input it to the BMD Tally GPI box and control crosspoint routing on a BMD video hub.
I cannot find any instructions to make it do this. I’m guessing it’s GPI in via the 25pin and the ethernet is connected to the video hub, either from a panel or from the ethernet router. I am also guessing the TallyGPI is programable for which cross points can be switched, or is it just 1 – 8?
Thanks
Richard
