1.5.6 Daisy Chaining
You can use multiple analyzer units for higher port count, by daisy chaining the units
through the provided Sync In/Out interfaces on the analyzer back. Connect “Out”
connectors to “In” connectors of the next unit in the chain. You must provide external
hubs
for connecting the host machine to these units using USB cables. You can daisy
chain up to four units.
Note: Because chain connections for daisy chained boards cause delay of signals, traffic on different
boards is not completely time synchronized, with about 100 nanoseconds of difference
between consecutive boxes.
