5.2.1. Transparent

Convert Server support serial interface transparent transmission mode. The benefit of this mode is achieves

a plug and play serial data port, and reduces user complexity furthest. In this mode, user should only

configure the necessary parameters. After power on, Convert Server can automatically connect to the default

wireless network and server.

As in this mode, the Convert Server 's serial port always work in the transparent transmission mode, so users

only need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In other

words, the serial cable of users’original serial devices is directly replaced with the Convert Server ; user

devices can be easy for wireless data transmission without any changes.

The transparent transmission mode can fully compatible with user ’ s original software platform and reduce the

software development effort for integrate wireless data transmission.

Notes:

Notes: Users also open the serial port hardware flow control (CTS/RTS) function, so that we can make the bit

error rate to a minimum.If the user doesn't need hardware flow control function of the serial port, only need to

the corresponding pin foot (CTS/RTS) hung up.

Convert Server supports the feature of binding the BSSID address of target network.

According to the provisions of 802.11 protocol, different wireless networks can have a same network name

(i.e. SSID / ESSID), but must correspond to a unique BSSID address (i.e. MAC address). Illegal intruders can

create a wireless network with the same SSID / ESSID, it will make STAs in the network to join to the illegal

Convert Server support UART free-frame function. If user select open this function, Convert Server will check

the intervals between any two bytes when rec ei ving UART data. If this interval time exceeds defined value

(50ms default), Convert Server will think it as the end of one frame and transfer this free-frame to WiFi port, or

Convert Server will receive UART data until 4K bytes, then transfer 4KB frame to WiFi port.

Convert Server ’ s default interval time is 50ms. User can also set this interval to fast (10ms) through

Through AT command: AT+FUARTTE=fas t /normal, user can set the interval time: fast (10ms) and normal

5.6.1.

5.6.1. TCP

This feature is available only on the Convert Server as a TCP server, when the TCP client connection Convert

Server , the Convert Server will authenticate each connected tcp.

Each TCP client first data is the “ password +0x0d+0x0a ” (the password is Webpage authentication password).

The default password is “ admin ” , so the first piece of data should be "0x61 0x64 0x6D 0x69 0x6E 0x0D 0x0A"

( Hex ). If the password is correct, the Convert Server returns "OK", on the other hand, return to the "NO" and

disconnect.

The TCP connection of this function can be Webpage in "TCP connection password authentication" is

opened or disable. Please refer to the specific "5.1.2" section.

5.6.2.

5.6.2. Upload

This function only applies to the Convert Server as a TCP client, in front of the data when Convert Server

connected to the server with two bytes of ID (ID the range is 0 ~ 65535, the high byte before, and the low byte

behind) plus two bytes ID radix-minus-one complement. Convert Server is the default ID is

is sent to the server when the first four bytes "0x57 0x04 0xfb 0 xa8".

There are two ways to upload their own id: one is to upload their own id for connection to the server for the

first time;The other is a plus id in front of each data.

ID number related parameter is set in the "serial port and other Settings" section of the web, build joint

function of ID for the first time, and each data with the function of ID are opened by default.

ID can also use the at command to set the related parameters, specific refer to 5.2.1.4.32-5.2.1.4.34 section.

 Status Two: The Convert Server will output “ Palmodic Signal ” after normal boot up.The palmodic signal

is 0.5Hz square wave with dutyfactor 1:1. User can query this signal to judge if Convert Server is active “ live ” or need to re-boot. When Convert Server switches to command mode, it will output “ 0 ” , which

used to distinguish work mode and command mode.
