RS422 is a balanced line version of RS232. In most cases, you can connect an RS232 signal directly to RS422, I have seen this work before. I don't have the RS422 pinout any more, unfortunately. Last time I saw single frame recording on a betacam, it had a SMPTE timecode generator reader installed to keep track of the frames (linear audio track timecode), and the company I worked for caused the deck to do single frame insert edits on a pre-blacked and timecode striped tape, via the RS422 port and custom software. SONY supplied us with a document describing all the RS422 commands. I don't have access to this info any more, the company went belly up a few years back. (AMPEX also second source the Sony Betacam, so give em a call too.) Hope that helps a bit. Gord Wait SMOS Systems Vancouver

I've seen SONY-machines here in Germany which do this definitly, but I don't know if this is "normal".
