TCP Server mode have 2 parameters: max link number and link type
1. max link number: 1 ~ 4;
2. Link type: typical, completely transparent, send data to all client;
extend1, communicate with id, otherwise abandon;
extend2, communicate with id, otherwise send to all client.
For link type extended 1 and extended 2:
When receive data from ethernet, module will send data to serial port with head ‘ I ’
‘ N ’ ,followed by data. ’ I ’ represent incoming data, ‘ N ’ represent client index.
When user MCU want send data to module serial port, start with head ‘ O ’ ‘ N ’ data... ‘ O ’
represent send out, ‘ N ’ represent which client.
When new TCP connection incoming, module will send ‘ C ’ ‘ N ’ ‘ M ’ to serial port, indicating
that there is current link ‘ N ’ accessed, total link number ‘ M ’ .
When link number have exceed maximum, new link requirment will lead to message ‘ F ’ ‘ F ’ .
When disconnect, module will send ‘ D ’ ‘ N ’ ‘ M ’ , represent current link N is delete, left link
M.
Note:
serial data need to be sent in one package to module.

This function is easier used for web page developer. We establish one web server page, add
this:
[<?php echo $_GET['data']; ?>]
Means we can GET data from HTTP client ’ s request. Open this URL:
www.usr.cn/1.php?data=12345 , the web page is downbelow, we can see that the web server have
got the data(12345),

It have 2 * RS232 interface. The serial port is male (needl), RS232 level (can be directly
connected to computer serial), part of RS232 pin sequences consistent to computer COM port.
When connected with the computer, we need to use cross cable (2-3 cross, 7-8 cross, 5-5 direct,
7-8 can don ’ t connect, but musn ’ t direcly connect to computer. Otherwise, it might lead to
irregularly work).
The DB9 interface contains the RS232, RS485 and RS422 interfaces.

RS485 two wirings terminal, A (DATA +), B (DATA), when connected with RS485, A (+) to
A (+), B (-) to B (-).
RS422 interface also connected to RS232 nine needles binding post. The device have RS232
and RS485 interface, but can only use one in a time, autoadaptation, connect as RS485 is RS485
function, connect as RS422 wiring is RS422 function.

Internet access port connection, module network interface is 10 M / 100 M adaptive, support
AUTO MDI/MDIX, can discretionarily connect cross-over or direct network cable. That is to say,
you can use direct cable to connect with computer or test.
