Figure 4-22. Synchronizing Multiple Channels
Note
To synchronize multiple channels, you must make the connections shown
in Figure 4-22 and configure the slaved channels for external synchronization.
This is done through Measurement & Automation Explorer or by using the NI-DAQ
function
SCXI_Configure_Connection
.Youmustnot configure for external
synchronization the channel that originates the synchronization signal from its EX+ pin,
channel 0 in the example of Figure 4-22, since it serves as master and is not slaved to any
other channel.
