EVAL-ADIN1200FMCZ HARDWARE
In the
Select Local
section (see Figure 13), a unique hardware
identifier is shown for each MDIO interface dongle connected
to the PC. In the example shown in Figure 14, there are two MDIO
interface dongles connected to the same PC (the A62UK21O and
AN3HD9WT).
The Ethernet PHY software GUI can only communicate with
one MDIO interface dongle at a time. To choose which MDIO
interface dongle is addressed as the local board in this section,
click the appropriate device identifier to select and highlight it.
All register controls, displayed link properties, and local board
information in other sections of the GUI apply to the selected
device connected to the MDIO interface dongle.
