1.PRODUCT OVERVIEW
1.1. General Description
The Eport Pro-EP20 Series is a fully self-contained small form-factor, most compact, integrated
solution, which provide a serial interface to Ethernet connectivity to web enable any device. The Eport
Pro-EP20 Series Series integrate TCP/IP controller, memory, 10/100M Ethernet transceiver, high-
speed serial port within a compact RJ45 package and integrates a fully developed TCP/IP network
stack and Linux OS.The Eport Pro-EP20 Series Series also includes an embedded web server used
to remotely configure, monitor, or troubleshoot the attached device.
The Eport Pro-EP20 Series Series using highly integrated hardware and software platform,It has been
optimized for all kinds of applications in the industrial control, smart grid , personal medical application
and remote control that have lower data rates, and transmit or receive data on an infrequent basis. By
simply adding an Eport Pro-EP20 Series Series unit to a product Design, device manufacturers can
reduce their Design cycle and speed up Time-To-Market with very low risk.
The Eport Pro-EP20 Series integrates all serial to Ethernet functionality into a low-profile, 50 x 23 x
11mm standard RJ45 module package that can be easily mounted on main PCB with application
specific circuits and even not change your original Design.
Eport Pro-EP20-PIN is Eport Pro-EP20 with PIN transformation board. The function is the same.

Base on customer detailed requirement, Eport Pro-EP20 Series provide different configuration version,
Details as below:
Figure 9. Eport Pro-EP20 Series Product Number Defination
2.11.Typical Application
Figure 10. Eport Pro-EP20 Series Hardware Typical Application
Notes:
nRST- Input.Hardware reset signal. Effective Low.
There is internal pull-up resistor to 3.3V and no external pull-up resistor needed. MCU put nRST signal
to low for at least 10ms if need to reset the device.
nReload- Input.Device restore to factory default configuration. Effective Low; (Recommend this pin
to connect button or jumper header, Used for batch upgrade and configuration)
Can connect with external button or chip pin, When press nReload button, pull the pin to Low level
more than 3s, then loose, device will restore to factory default setting and restart itself. If nReload
function is not required, Can leave this pin open, Don’t need any connection.
TXD/RXD- UART port data transmit and receive signal.
