Chart2-2. Function Circuit
3. PCB Interface
NEPORT can provide up to three high speed serial ports with standard CMOS signals which can tolerate 5V TTL signals. In the real application, NEPORT's serial port directly connect to the local CPU(or other processor) , then user devices can connect to Ethernet through NEPORT now,serial data from local cpu will be sent to NEPORT,and NEPORT will convert the data from serial port to Ethernet according to the networking configuration

RS232 Interface There is one onboard RS232 chip from SIPEX, it is used to convert 3.3V COMS signals to RS232 signal, normally, RS232 interface provide one DB9 connector to communicate with external DTE, for instance, connect to PC serial port. Chart 2-11. DB9 Pin Information

Mark1. Pin not listed in the above sheet is not used by evaluation board 2. Recommend to make the shield of DB9 connect to ground Power On board DC JACK with internal size : 2.0mm,power circuit support pole protection input voltage arrange:7.5V~12Vadjustable power chips are LM2596 DC-DC and LM1117-3.3V LDO from SIPEX Selectable Channel Switch The Evaluation board provide 8bits DIP16/8 switch to select NEPORT1 or NEPORT2 to communicate with external rs232 interface. Push switch to ON will enable the corresponding signal. Attention 1. User just can enable one group of this 8bits switch,(group 1:one:1-4 , Group 2:5-8), or Evaluation board can't communicate with external rs232 devices 2. When all of 8bits switch are disconnected or one group are disconnect but no NEPORT on the other group, such setting may cause no signal output to rs232 8Pin/2.0 pitch header The Evaluation board provides 8pins pitch header for OEM/ODM customized development, and this pitch header can make NEPORT signals connect to user's MCU/DSP efficiently to debug or testing according to the real application Attention Should disconnect the extern rs232 interface to avoid effect testing result Buttons The Evaluation Board integrates three buttons used as reset / defaulting setting
