GPSDO in kit No, the 4 pin connector is at RS-232 levels. It connects to an RS-232 level converter chip. These "UCCM" devices speak SCPI at 57600,8,N,1 I have Lady Heather talking to them (soon to be released, I promise). I have tested it with four different firmware versions (all have some slight differences). Most of the NMEA data sent from the receiver is proprietary Furuno commands. KO4BB.COM has a manual for the receiver... ------------------ Looking at the fifth picture on the ebay link, at the top left corner next to the SMA connector just below R13 is a vertical row of holes. That is the main serial connection and it is at TTL levels. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts time-nuts Info Page - American Febo Enterprises<https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts> www.febo.com time-nuts is a low volume, high SNR list for the discussion of precise time and frequency measurement and related topics.
