1.10.1 Cascading with STX SYNC Expansion Cards
You can use cascading of analyzer units for higher port count, by daisy chaining the units
through the provided Expansion and Clock In/Out interfaces on the analyzer front.
Connect “Out” connectors to “In” connectors of the next unit in the chain, for both Signal
and Clock interfaces. You must provide external hubs
for connecting the host machine to
these units using USB or Ethernet. You can cascade up to eight units. Use the STX SYNC
Expansion Cards to sequentially trigger the State Machine in Advance mode.
If you mix Sierra M6‐4, Sierra M6‐2, and STX A6‐4 analyzers/emulators, put Sierra boards
first, then STX.
Note: Because chain connections for cascading boards cause delay of signals, traffic on different
boards is not completely time synchronized, with about one DWORD difference between
consecutive boxes.
1.10.2 Cascading
To set up the units in a cascade:
1. Connect all units to the host machine using either USB or Ethernet cables. You can
use hubs.
2. Locate the Expansion and Clock ports on the front of each unit.

3. Connect the OUT Clock connector of Unit 1 to the IN Clock connector of Unit 2 using
the supplied stacking cables. Similarly connect any additional units.
4. Connect the OUT 10‐pin connector of Unit 1 to the IN 10‐pin connector of Unit 2
using the supplied stacking cables. Similarly connect any additional units.
Note: Unit 1 must be the unit that has the first out connection
Note: The Self Test, SAS Verification Test, SATA Compliance Test and Update License functions only
work on unit 1 when the analyzers are set up in cascading mode.
