4.2 DIP-Switches and Operation Modes

The four DIP-Switches on the media converter board are used to select the desired operation mode and configuration. Possible operation modes are:

Normal mode: In this standalone mode, the onboard MCU configures the PHY based on the selected settings and shows status information with the onboard LEDs. LED8 green for normal mode, LED9 green for standard configuration applied. When SW 2 off, LED10 on depending of signal quality indicator from 720 PHY MDI side.

Normal mode without configuration: LED8 green for normal mode, LED 9 red for non-configuration applied. When SW 2 off, LED10 on depending of signal quality indicator from 720 PHY MDI side.

Sleep Mode (for EMI testing): Standalone mode. After applying the selected configuration, the MCU shuts down to minimize EMI emissions. The sleep mode is indicated via LED8 (on) in red.
