    AF-4500 Serial specs

    Hello,

    Do the serial interfaces on the AF-4500 conform to true RS-232 signal levels (around +10 to -10 volts) or are they TTL signal level (0 to +5v)?

    This tells me if I need a signal level converter or not, and saves me from breaking out my scope.

    Also, do you know if garmin stuff is RS-232 or not? Specifically a 430W and a 495 portable?

    Thanks,
    schu
