The XCPCI-002G is a time-based terminal board based on the CPCI bus, which is used to receive the Beidou II (hereinafter referred to as Beidou), GPS navigation signals, and B (AC) and B (DC) time codes. It also generates and outputs multiple high-precision time signals and geographical location information, and communicates with the host through the CPCI bus to accurately time and locate the system.
The computer system can read the synchronization time and the coordinate value of the antenna through the API function, and can also control the working parameters of the time code card through the API function and monitor the working state of the time code card.
Features
● A variety of timing signals are available;
● Built-in high-stability crystal oscillator;
● CPCI bus interface;
● The driver supports Windows XP/Windows7/VxWorks5.5 and VxWorks6.8 operating systems.
