I don't know about the 3805 or 3816, but the 3801 is RS-442 rather than
RS-232. It's all setup to talk RS-232, but you have to take it apart and
shuffle some 0-ohm resistors. While you are in there, you can make a similar
patch for the PPS signal.
These are my opinions, not necessarily my employer's. I hate spam.
