TransparentTransparentTransparentTransparent TransmissionTransmissionTransmissionTransmission ModeModeModeModeConvert Server support serial interface transparent transmission mode. The benefit of this mode is achievesa plug and play serial data port, and reduces user complexity furthest. In this mode, user should onlyconfigure the necessary parameters. After power on, Convert Server can automatically connect to the defaultwireless network and server.As in this mode, the Convert Server 's serial port always work in the transparent transmission mode, so usersonly need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In otherwords, the serial cable of users’original serial devices is directly replaced with the Convert Server ; userdevices 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 thesoftware development effort for integrate wireless data transmission.Notes:Notes:Notes:Notes: Users also open the serial port hardware flow control (CTS/RTS) function, so that we can make the biterror rate to a minimum.If the user doesn't need hardware flow control function of the serial port, only need tothe corresponding pin foot (CTS/RTS) hung up.

Illegal intruders cancreate a wireless network with the same SSID / ESSID, it will make STAs in the network to join to the illegalAP,thereby and then network leakage happen.Users can preventSTAfrom joining to illegal network by binding the BSSID address, to improve wirelessnetwork security.5.4.5.4.5.4.5.4. UARTUARTUARTUART FrameFrameFrameFrame SchemeSchemeSchemeScheme5.4.1.5.4.1.5.4.1.5.4.1. UARTUARTUARTUART Free-FrameFree-FrameFree-FrameFree-FrameConvert Server support UART free-frame function. If user select open this function, Convert Server will checkthe 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, orConvert 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) throughATcommand. But user have to consider if user MCU can send UART data with 10ms interval ,or the UART datamay be divide as fragment.Through AT command: AT+FUARTTE=fas t /normal, user can set the interval time: fast (10ms) and normal(50ms). This command is factory default setting command and AT+RELD can ’ t change its value.5.4.2.5.4.2.5.4.2.5.4.2. UARTUARTUARTUART Auto-FrameAuto-FrameAuto-FrameAuto-FrameConvert Server support UART auto-frame function. If user select open this function and setting auto-frametrigger length and auto-frame trigger time parameters, then Convert Server will auto framing the data whichreceived from UART port and transmitting to the network as pre-defined data structure.Auto-frameAuto-frameAuto-frameAuto-frame triggertriggertriggertrigger length:length:length:length: The fixed data length that Convert Server used to transmitting to thenetwork.Auto-frameAuto-frameAuto-frameAuto-frame triggertriggertriggertrigger time:time:time:time: After the trigger time, if UART port received data can ’ t reach auto-frametrigger length, then Convert Server will transmitting available data to the network and bypass theauto-frame trigger length condition.
