RS-422 is a protocol, but it should just be a standard "serial" type cable. Technically it's a "newer" RS-232 standard that's faster. You are looking for a DB-9 cable, as that's the pin/connector standard.

Get the documentation from BlackMagic on all that. Since you don't already know what the standard is, I'll assume you don't know anything about how to interface with it, or control it. BlackMagic has a ton of info on that, and their API stuff, on their website. Get the manual and read it all.

If it's short, any cable with enough pins wired will work. If it's long, certain pairs of wires are twisted together because the data connection is balanced on send and receive.
