A special cable to synchronize data acquisition from several boards is
required ( PD-CBL-SYNC4 See Appendix) . This cable has one master
connector and three slaves. (Custom versions of this cable are available
for more than 4 boards in one system). It connects the CL and CV clock
outputs from master board to CL and CV clock inputs of the slave
boards. To synchronize multi-board acquisition you should program the
master board CL (or CV) clock to use internal, external or SW clocking
and the slave boards to use external CL (or CV clock). Any of the
Methods A thru D can be used.
The best way to set up multi-boards operation is to launch separate
execution threads for each board. Start the slave boards threads first
and then the master board thread.
