If you are using a desktop, I'd suggest putting in a serial card. The Netmos chip based cards work on windows and linux, though your should do an internet search on the particular card before you buy.
I have the prolific based converter. It didn't work with my Starloc. (The netmos worked fine with Lady Heather.) I just got a Gearmo branded FTDI based usb to serial. I haven't tried it on the Starloc, but it works well on other devices. -----Original Message----- From: Sarah White <kuze...@gmail.com> Sender: time-nuts-boun...@febo.com Date: Sun, 19 Aug 2012 00:25:51 To: <time-nuts@febo.com> Reply-To: Discussion of precise time and frequency measurement <time-nuts@febo.com> Subject: [time-nuts] L1 GPS timing signal(s) into local time on computer(s) Hi, this is my first post. First off. Windows 7 USB connection to the GPS (no serial ports / modern computer) and I'm pretty sure that is my main problem. Past few months, I've been trying to figure out my timing issues. Lots of reading & trying to figure out how to best configure everything. I'm typically still off (randomly) by 20-100 miliseconds. I'd like to at least get to within 50 microseconds (nanoseconds would be wonderful) 1) I need a computer with a serial port. The curent GPS module I'm using is INTERNALLY RS232 --> USB converter, and recognized by my windows 7 computer as: "Prolific USB-to-Serial Comm Port (COM3)" ... the latency and jitter is horrible, and both are seemingly random. 2) I need to run my stratum 1 clock (connected to the stratum 0 time source via old-school RS232 serial) on linux or a form of BSD with support for kernel timestamps, and a version of NTP with a driver to supports my reference clock... points 1 and 2 seem fine. 3) I'm clueless about mounting an antenna, running cable, grounding / lightning protection, etc... Really want an easy to install one. For software, I've used 4.2.6 (stable / production) as well as 4.2.7 (dev version) NTP and haven't been able to tell any difference. Just using the generic NMEA driver / this is a no-name cheapo SIRF module. Also, trying to wrap my head around these: http://linuxpps.org/wiki/index.php/LinuxPPS_installation http://linuxpps.org/wiki/index.php/LinuxPPS_NTPD_support And here is where I give up. As the subject line suggests: HELP!!! I'd like to convert L1 GPS timing signal(s) into local time on computer(s) _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
