The Z3801A comes setup for RS-422. The board is setup to support both RS-232 or RS-422 depending on jumpers or 0 ohm resistors. Pictures here: http://support.ntp.org/bin/view/Support/Z3801AReceiverModifications It's pretty obvious after you take one apart and poke around with an ohm meter. You can put a few of them back in different slots rather than the actual jumpers in the pictures. -- These are my opinions.
