2.11 Quick-Start Guide (SMBus Slave Mode)

Configure all devices to operate in the SMBus Slave Mode by setting their MODE pins to the L1 level, each redriver is assigned a unique SMBus secondary address. This is accomplished by placing shunts as shown in Table 2-11.

  1. Connect USB2ANY or Aardvark Adapter to P4 (Note that the Adapter is not supplied with the DS320PR412-421EVM). Install shunt on JMP17 across pins 1-2 for USB2ANY, 3-4 for Aardvark.
  2. Install SigCon Architect Version 3.0.0.16 application and the DS320PR412-421 profile.
  3. Plug the EVM into a PCIe x16 server motherboard slot. Ensure the motherboard is powered down before installing the EVM or configured for hot-plug operation.
  4. Install a compatible PCIe endpoint card into the straddle connector of the EVM.
  5. Power-up the motherboard.
  6. Start the SigCon Architect application.
  7. Select the DS320PR412-421 Configuration Page and select the Apply box to enable the device profile. If necessary, edit device addresses in the Edit Device Addresses box.
  8. In the DS320PR412-421 High Level Page, select Block Diagram as shown in Figure 2-1.
  9. Select desired EQ Settings and Driver VOD.
  10. Select the devices to which you want to apply the selected settings and click the Apply to All Channels button.
