don't count on it to hold an accurate jam, i would use a syncbox to keep an accurate jam. and to get timecode into it you're going to need a padded cable as timecode coming out of af100 is line level. but after all of that, might as well get a real slate like a denecke ts-c or something similar.
I use MovieSlate with an AF100. I bought cables from the vendor MovieSlate recommended. It works very well, with the usual jam sync drift over time caveats.
