AJA IO Basic question
Hello. I am familiarizing myself with HD technology and integrating Final Cut Pro into different configs. After reading the specs of the AJA IO, I didn’t understand why the IO had a RS 422. I understand a deck being slaved by an NLE with a 422 but seeing a 422 on the back of the IO confused me.
thanks

VTR’s are controlled by the RS422 protocol, popular with Sony and Panasonic. You have a RS422 port on the back of the AJA I/O, so that you can use this to control your Sony or Panasonic VTR via RS422 – this happens thru the Final Cut Pro software.
Unless you purchase an adaptor, like a Keyspan USA-28X, there is no other way to control a Sony RS422 VTR from a Macintosh computer.

I’ll add to that; you are saving system resources by using the serial port on the AJA box. Otherwise, as our collegue states, you have to add a third party serial adapter to your system. It’s not really 422 control; it’s the serial connection to your computer “from” the 422 control port on your deck. That make sense?
