Thanks for all your help.
Having checked the studio configuration / video rack a little deeper I found that in fact there is an rs422 cable connected to the sony J30, but this is connected to a BlackMagic-Design VideoHub that was installed some time ago.
This has 16x rs422 connections, one of which travels under the floor to this Mac Pro but is plugged into a AJA IO. I have moved this and connected it to the Kona 3 cable RS422 connection, but get nothing, no video, no deck control. If I bypass the videohub by connecting the SDI cables together I get Video IO but using the VideoHUB I get nothing.
I cannot bypass the RS422 on the video hub as the distance between the machine in the video rack makes it difficult.
I have installed the VideoHub software, but all options are blank and have no ability to manage the connections. The videohub is connected direct to this mac using the USB connection.
Does anyone know about the videoHub here, it’s asking for an IP address for the videohub, how do i find that?
struggling with the BMD software / hardware..
thanks for any advice.
