20db USB-támogatás a COM-modul kábeléhez USB-RS232 TTL UART PL2303HX automatikus konverter
20pcs USB Support to COM Module Cable USB To RS232 TTL UART PL2303HX Auto Converter
 
Line sequence defined red 5 V, black GND, green RXD, white TXD
 Special note:
(A) the connection just to sell a small plate, a tool. We use are not familiar with, they can not provide operational guidance. Many models on the market, and the abilities of each person and far, so we can not be maintained that you can succeed. Not because he did not succeed and give us neutral or negative feedback, then we blame than Dou!
(B) We sent out a tested, to remind buyers do not get directly after the operation, in order to avoid not think there is a problem. First do a simple test is simple: if you put the line plugged into the computer, the computer prompts "Found New Hardware ...." connected (GND) with a multimeter black pen, red pen to pick up (RX) and (TX) voltage can be measured, then the small plates must be good. Special instructions here (GND) to the voltage pins, power must be burned, so user wiring must be accurately measured the pins of the device, so as to avoid unnecessary losses!
Some buyers are not careful burned chip or not operate or machine itself does not support the upgrade, say, our board Please buyers Bypass, thank you. Such a situation does not give return or refund the behavior of not receiving the assessment and Poor.
 
Note: 3.3V and 5.0V output is set (this is the power supply to the microcontroller, upgrade machines do not need the small plate) unplugged from the computer, set the jumpers to take, do not live to avoid damage to the equipment.
Pin connection and description:
The wrong connection be sure to find the pin definitions, especially GND must not be connected to the voltage on the pin, and the RX and TX terminal is not connected to the VCC pin (actual measurement of some VCC pin voltage up to 14V.) shall be burnt adapter cable chip, certain note, do not take their own small plate to experiment, or burn We are not responsible. Must find the pin definitions in the next.
Connection method: repeat Brush only need three lines, generally used in the RX TX GND three signal lines, the VCC without access. The above 4,5 needle friend, not connected to VCC and BT needle. Use RXD connected with the target board TX phase, TXD and target board RX, GND connected to GND if not, swap RX and TX.
All modules have been double test factory!
 
The home must-see:
    Friends have bought this board electronic basis. At least to recognize the RX TX GND VCC these things, do not know, please do not buy, you buy, it will not get.
    Again affirm the electronic-based do not buy! ! We sold every one module after the owner personally tested in good condition before the issue of security hand intact after the buyer received the goods do not blindly up into the circuit first understand clearly the wiring operation, module products, once sold rebate does not change, all buyers are aware of! ! !
Note that we do not provide the upgrade tutorial. USB to TTL upgrade board and teach you how wiring.
  Some buyers are not careful burned module or not or does not support the upgrade of the machine itself, say, our module, buyers Bypass, thank you. This module does not give return or refund behavior.
 
Connection:
RX TX;
TX RX;
Ground-to-ground (GND GND)
USB-to-serial board features:
  A simple serial communication.
  2 router or ADSL firmware upgrade.
  3 GPS serial communication.
  4 hard drive firmware upgrade.
  5 easy to use, RX to the MCU TX; TX received the MCU RX connected to. Without the need to use MAX232 conversion.
  6 HyperTerminal; popular serial debugging tools.
  7 various satellite upgrade.
    ............... Universal USB to serial board
 
Module use
1, install the driver,
 
2, restart the computer,
3, the module plugged into the computer's USB port, the system will automatically install the driver
4, TXD and RXD connected (that is, with a the DuPont line a plug a plug TXD RXD) module spontaneous admission
5, open the [Serial debugger]
XP system installation process:
First, download the drivers, Click the icon to start the installation, click Next until the completion.
Installed correctly; Device Manager - Port - see the USB-to-Serial Comm Port (COM3 / COM port you connected the USB interface will display different)
 
Two small plates into the upgrade, the system will automatically load the driver for it. Note: DuPont line shorted TXD and RXD to function properly test module.
Modify the following, and press the corresponding prompts, you can test whether the module normal work.
