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
