Synchronization - Master and Slave tasks.

For syncrhonisation (via hardware) of two modlues; one 4330 and 6361, shall I create one master task for the 4330 and then syncrhinise it with the 6361 module? Or create multiple channels say 5 from 4330 and 5 from 6361 and then specify one channel from 4330 to be the master and all the rest modules from 4330 and 6361 to be slave tasks?

Thanks,
