TP9801 Network Time Server


TP9801 Network Time Server is the professional network equipment providing high-stable time source. TP9801 network time server receives GPS satellite signals and extracts the timing information to adjust the server's local time. It distributes standard time via NTP protocol (Network Time Protocol). If a PC or server needs time synchronization services, it will run a client program to read the NTP protocol, derive time information, and modify the time of related equipment.
