Paul and Hal, I think there may be some confusion here. I modified the Z3801A to RS-232 way back when I first got it. My recent post was just discussing some of what's in this demo/testing unit thing. It's just a translator for TTL/RS-232 for when the GPS RX board (TTL serial) is used by itself, hooked to a PC (RS-232), so the WinOncore SW can talk to it. When the RX board is inside the Z3801A, it's controlled in that environment.
These days, since PCs don't have serial ports, you can buy a RS422 USB adapter for $5. If I were doing it now, I wouldn't bother reconfiguring.
