The Configuration page of the DS160PT801 profile in the SigCon Architect GUI is the only page enabled after starting the software. This page is intended to be used to configure a connection to the EVM's onboard retimers through the USB2ANY interface for full access to the retimer functions. To establish a connection, the SMBus address for the link-width manager and link-width follower should be specified in the provided dropdowns. After the valid SMBus addresses are specified, the Apply button is used to establish the connection. The following are descriptions of the various input fields of the Configuration page:

  • Manager Address Dropdown specifies the SMBus address of the link-width manager.
  • Follower Address Dropdown specifies the SMBus address of the link-follower.
  • Toggle LED Button can toggle an onboard LED and can be used to confirm a successful connection.
  • Apply Button attempts to establish an SMBus connection to the onboard retimers. If a connection is successfully established, the other pages of the DS160PT801 GUI will be enabled.
  • Online Documentation Button connects to online documentation for the DS160PT801 on ti.com.
  • Demo Mode Checkbox may be used to enable GUI demo mode. In this mode, all features of the GUI are enabled to demonstrate the features of the GUI without an active retimer connection. This may be used to create EEPROM images, view the register map, or evaluate other portions of the DS160PT801 GUI.
