It sends a single invalid command requesting auto messages and then parses the data stream. As long as primary timing packets are received it works. A Thunderbolt will wake up doing the right thing and if not I believe LH will correctly initialize it. The deeper point is correct and the Trimble devices I have experience with have ~100ms of jitter. Props to Jackson Labs -- my Fury has O(10) microseconds of jitter using NMEA messages. If only they were $100. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
