This generator sends PPS signals over a parallel port from one computer to another. So it's just doing what every PPS-capable GPS device does. I use it to precisely synchronize time on several computers for distributed real-time simulation. It has very strict timing conditions. --=20 Alexander --Sig_/PaDqkf/Ad9.M2_YN4kirOiW Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQEcBAEBCAAGBQJLbS8HAAoJEElrwznyooJbfI4H/iNacJizbVbdbVH/K5DfTruj uVLYBwgkFqAML+Ewbwkb8UKrMCjloyf1+ws7HKCowh3KwvMhVk2jly1+Dalmz6hO DLkEJuPSAegGQHiiHlnqMKY7RVwzuNl5t+0yNdV9tmCVxjihMN0OTbmcyUyX7Ztc LzumrqShcX/VXH4at2GcJB4/1QCi3Ul5VY/6S+GH78K8A6X1Zzl7BkNZbWSjV48A PpudKMDZAEz7i8j+zo2VS687hI1Q08DRNOCMwjIDKCaGfX7Nt9MOaoakTJVm4t3E bFjGrFB4ZnALiv+LfeBw1zAXT9OLem8FSNmzTG+zC6wBnsMxF2VUP8j9dcNeuww= =1C1/ -----END PGP SIGNATURE----- --Sig_/PaDqkf/Ad9.M2_YN4kirOiW-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
