The synchronous control connector (SC connector) offers an easy way to synchronize the operation of two or more boards (same kinds or different kinds) by using the start signal, clock signal and stop signal etc. in common.
It is used in cases such as when you want to increase the number of board channels, and when you want to perform digital I/O and analog I/O at the same time.
The synchronous control connector includes synchronous signal lines from EXTSIG1 to EXTSIG3. The board that outputs the signal is called master, and the board on the receiving side is called slave. In the group of synchronous boards, only one device can be set to master, and all the others are set to slave.
By specifying synchronous signal lines from EXTSIG1 to EXTSIG3 to start condition, clock condition and stop condition, the slave can be operated synchronously by master signal.
On master side, set what kind of signal you want to specify to synchronous signal lines. The signal includes internal clock and external start etc. of a board. Please refer to the specification of the CntSetMaster function for details of the signal type that can be specified to synchronous signal lines.
For how to specify start, clock and stop to EXTSIG1, EXTSIG2 and EXTSIG3, it is recommended that it should be done in order of specifying clock to EXTSIG1, start to EXTSIG2 and stop to EXTSIG3.
On slave side, set whether validate the input of synchronous signal lines, and which one you want to use from EXTSIG1 to EXTSIG3 for sampling condition of start, clock and stop. The signal other than synchronous signal lines can also be used for slave's sampling condition. For example, it is possible to use only start signal and stop signal of synchronous control connector, the clock signal can use the internal clock of master.
The synchronous control connector is CN2 and CN3 on a board.
Please use the attached connector to a board for the connection.
