For example, when two boards are used in respective condition, the sampling
setting and start operation are performed for each board separately.
In this case, set stand-alone for the mode setting.
Other than that, when two or more boards are used aiming at increasing the number of channels etc., though there is a method by using external clock etc. in common to use start, clock and stop synchronously, the other way by synchronous control connector (SC connector) can avoid special external wiring.
The synchronous control connector includes synchronous signal lines EXTSIG1 to EXTSIG3, by assigning them to start condition, clock condition and stop condition, the slave can be operated synchronously by master signal.
In this case, please start the slave device first for sampling.
The CntSetMaster
function is used to set a board as a master, and define what signals to
output on the synchronous signal lines EXTSIG1 to EXTSIG3.
The CntSetSlave function
is used to set a board as a slave, and specify whether or not to use the
received synchronous signals EXTSIG1 to EXTSIG3.
Start condition setting function (CntSetSamplingStartTrg),
clock condition setting function (CntSetSamplingClockTrigger),
stop condition setting function (CntSetSamplingStopTrigger)
are used to
assign the signals EXTSIG1 to EXTSIG3 to the actual start, clock, and stop.
