IGURE A-12: CONFIGURATION EXAMPLE
When a new system is created, it contains “TTL1” in the Parallel I/O Groups folder and
references the default component library. If desired, the user can click on System in the System
Explorer pane and can use the fields provided to differentiate one system from another, although
this is not required to configure a system.

IGURE A-13: SYSTEM PROPERTIES WINDOW
To add the relays, select Add Relay from the Add menu. Here, we will select the “VTI 7202-20
(SPDT)” from the drop menu. Per Figure A-12, “SW1” is entered as the relay name. Once this is
completed, the Add button is clicked. These steps are repeated for SW2, SW3, and SW4. Once all
relays have been added, the Add new relay prompt can be closed.
