Issue Details

I am looking at purchasing multiple ethernet cDAQ-9189 chassis. How many can be chained together and synchronized? 


The number of ethernet cDAQ chassis that can be chained together is dependent on the chassis and topology used for the application (as explained here ). For the cDAQ-9189 chassis, the maximum hops per line is 15, so you can daisy chain (line topology) up to 15 ethernet 9189 chassis together and synchronized them. This also works for the cDAQ-9185 chassis.
