Grass Vally switcher controlling a computer running Isadora

craigw

Hi All, I use a Grass Valley Video switcher and would like to control video clip playback with Isadora from a computer.

The Isadora side I'm very familiar with, it's the different protocal languages coming from the switcher that I'm trying to put together to send Isadora commands like Play, Stop Rew and more if I can.

My Current Choices:

1, Contact closure, would work but it's so rudimentary and I would need to setup many triggers, but it's really easy.

2, RS-422, VTR/BVW, this has been around a long time and is probably what I'll settle on because I'm not a coder, but trying to learn.

3, AMP (Asynchronis Messaging Protocol) I'm most interested in this because it's IP base and makes a clean install, however as I said I'm not a coder and I'm having problems on where to start.

4, There are some other Protocols but most of them are proprietary.

Thoughts?

I'm starting my deep dive today.

@craigw

Could you provide a link to the model of the device and any available technical documents?

I'll take a look at what they offer.
