TAC32 is a PC program offered by Rich Hambly, who does business as CNS Systems, Inc. <http://www.cnssys.com/> It will control several varieties of Motorola GPS receivers, especiallythe M12+T, using the Motorola binary format. It can also interface to other GPS receivers using a more limited NMEA-0183 message protocol. It accepts the 1 pulse-per-second output of the GPS receiver and can use it to set the PC's clock. TAC32 or its enhanced versions is also the PC program used to control the "CNS Clock" and "CNS Clock 2" hardware from CNS Systems. These gadgets have a variety of interesting options, such as acting as an NTP time server or as a source of IRIG-B time code. The most interesting option to me is the "High Performance PPS" option, which provides a better 1 PPS pulse train than the one available directly from the CNS Clock 2's internal Motorola M12+T receiver. -- James Maynard Salem, Oregon, USA _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
