Time Code with GenCG, AutoCast, or NewsScroll
If you are running a clock in GenCG or other Compix software (except in certain sports applications), the information comes from the Date & Time Properties on your Microsoft Windows operating system. There are options for syncing the computer clock with an external source.
Traditional GPS/Time Code
The traditional method of synchronizing the computer clock to an accurate time clock has been through using a PC based time code card to receive data from a master time clock. This master time clock receives the time code from a GPS, TCP/IP based network, or dial-up system.
The data dlow is similar to this:
Note: The GPS Antenna will pick up GMT time every few seconds or minutes.
This method is still used often in large facilities that can afford the GPS, clock, and T/C equipment. You can add an aftermarket time code card to the Compix system, as long as the current Windows operating system is compatible. Compix does not have a recommendation list for any specific manufacturer and has not completed any testing.
Computer Network Time Protocol (NTP)
NTP is often used as a method to sync PC-based computers to a time source. It is described in the Wikipedia link here: http://en.wikipedia.org/wiki/Network_Time_Protocol
Network administrators are usually familiar with the setup. Here is a diagram of the data flow:
