USB Interface
The USB interface can be used to insert a USB storage device. The port can be used only for audio
playback.
LAN
The LAN interface is used to connect to a PC or Ethernet switch for system configuration. User can
set the function and parameters via Ethernet via the configuration software.
Be sure to use the cross cable to connect the MCU LAN interface with a PC according to T568A and
T568B standards. If the MCU needs to be connected to an Ethernet switch, both cross and straight
connections are available since the switch has Auto-MDIX function. For 100m transmission distance,
cross cable is recommended. A twisted pair (2m) is provided in the package for connection.
