Be careful of the pps output from the dual lucent boxes. Tried to use it to sync SL and found that it is a weird non-standard pulse and would not work even with a pulse stretcher as it looked too narrow. I use the pps output from a Jackson unit and it syncs SL fine.

It's in the mail archives. Google for something like >time-nuts RS422 pinout<
If you are interested in timing, you want the PPS signal too. (It won't be great over USB, but it might be fun to play with. You can get your own hanging bridges.)
These are my opinions. I hate spam.
