1 Getting Started and GUI Overview

The following section describes the steps needed to install the Texas Instruments SigCon Architect GUI and the DS320PR410 SigCon Architect GUI profile.

Download and install the Texas Instruments SigCon Architect GUI EVM v3 program. Follow the steps in the SigCon Architect: Installation and Starter’s Guide for detailed instructions.
Download and install the DS320PR410 SigCon Architect GUI Profile Updater from the TI website or secure resource folder.
Connect a USB2ANY Interface Adapter or Aardvark I²C Host Adapter to the desired DS320PR410 and PC.
Launch the SigCon Architect EVM GUI v3 program and make sure that the DS320PR410 profile has been installed. When successfully installed, the program is shown as an instance of the DS320PR410 device below the Selection column of the SigCon Architect GUI.

Descriptions of each DS320PR410 SigCon Architect GUI page are listed in the following:

Configuration Page: Used to configure device SMBus/I²C Addresses, device EVM model, number of devices (in DS320PR410EVM-CUSTOM mode only), and interface adapter.
Note: The Configuration Page page must be configured before accessing any of the additional GUI pages.
Low Level Page: Individual register access to each device. This page can be used to change specific register settings or to verify that changes from the High Level Page have taken effect.
EEPROM Page: Used to create, read, and write EEPROM Hex files (following Intel™ Hex format). When the DS320PR410 is configured in SMBus/I²C primary mode (MODE = L1), the redriver loads the settings stored in an external EEPROM upon power-up. The user can configure these settings using this page.
High Level Page: Main page used to change EQ settings (EQ Index/CTLE, DC Gain) of the device and to monitor the active status of each channel.
Eye Height Page: Used to perform an EyeScan of selected channels and display the EyeScan result plot in graphical form. This can assist in tuning the DS320PR410 and choosing an EQ Index for your system. Please refer to the Eye Scan with TI PCI-Express Gen5.0 Redrivers application note for further details.
