So we want the LVC version to get NMEA plus 1PPS. In the documentation I see a small diagram to connect the GPS-18 to the RS232 port. - The power I could get get from a USB port I guess? - The 1PPS signal to DCD? Or DTR? Besides the hardware and getting the GPS-18LVC at a reasonable price, what software patching and configuration is required? Kernel patches for 1pps? LinuxPPS? http://www.enneenne.com/index.php?appl=menu&request=Projects&name=linuxpps Or can I do without? Then the ntpd tweaking, the old ntpd site is gone? _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
