Hardware Setup for Direct USB Connections
Connecting multiple analyzers to a single PC by USB gives you the convenience of being
able to control multiple analyzers from a single SASSuite application. The application
provides you with a means of toggling back and forth between the different analyzers that
are connected.
To set up multiple analyzers via USB, you attach
USB cables between the analyzers and the host
PC as shown in the illustration on the right. If you
do not intend to group the analyzers together for
synchronized multi-analyzer recordings, no
further hardware setup is required. If you do
intend to group the analyzers, then you will need
to add connection cables as described in the section below under "Setup for Multiple
Analyzer Use." Once the analyzers are connected and started, you can browse to the
analyzers via the command Setup > Analyzer Network ...
Note: The SASSuite software will allow you to toggle between the
analyzers but not run two copies of SASSuite software on your
screen simultaneously.
Setup for Cascaded Multiple Analyzer Use
Using
Multiple
SASTracer
Analyzers
SASTracer Analyzers are connected in a cascade using the "EXT IN" and "EXT OUT"
BNC connectors on the rear of the chassis. SASTracer supports up to four analyzers
connected together in a cascade.
If you add a BNC connection between the
analyzers shown, you create a cascade
which allows the analyzers to function
together as a logical unit. Cascading
increases the numbers of ports that can be
simultaneously recorded.
To set up a cascade, you connect a BNC
cable between the External Output port on the back of one
analyzer to the input port on the second. The first analyzer will
serve as the controlling or master analyzer. It will transmit clocking
information, Recording Option commands and other data to the
other analyzers. If you plan to group three or four analyzers
together, daisy-chain the remaining analyzers together, and then
loop the output of the last analyzer to the input of the first analyzer
as shown in the figure on the right.
Note: For SASTracer Analyzers, the BNC cables must
form a complete loop by connecting a BNC cable
from the last analyzer’s "EXT OUT" port to the first analyzer’s "EXT
IN" port.
