Overview
The LabView Driver for the Spectracom TPRO/TSAT PCI-U boards provides the interface for
multiple users to access the board. The TPRO-PCI-U is a precision clock that automatically
synchronizes to standardized time code signals or (for TSAT-PCI-U configuration) to the GPS
satellite system and can be read from the host computer.
Inputs to the TPRO-PCI-U are modulated time code (or GPS receiver signals for TSAT-PCI-U),
host commands, and time tags.
Outputs are modulated IRIG-B time code, programmable start/stop time, and a programmable
"heartbeat" pulse rate.
The board also can generate interrupts on the PCI bus (if enabled). Interrupt sources include
the heartbeat, time tag, FIFO data available, and/or at the programmable start time.
The clock will automatically synchronize to specified time code signals. A status bit advises the
host of synchronization status. In the absence of Timecode input or GPS the board will start
counting at 000 days, 00 hours, 00 minutes, 00 seconds at power-on. The clock time can also
be set by user command.
