J ai compris qu il suffit d avoir un cable de communication pour téléphone portable par exemple futuredial usb data cable de couper du coté prise téléphone et de brancher le bon fil du cable dans le bon trou du coté de la carte mère.
Rx tx gnd usb cable.
The power pin provides the 5v 500ma direct from the usb port and the rx tx pins are 3 3v level for interfacing with the most common 3 3v logic level chipsets.
The connetors fit on standard 0 64mm pins.
Also a usb to serial phone cable will work in most cases.
If everything works so far connect the probe to the probable candidate to tx pin and type something into the terminal window choose lower baud rate in the terminal settings something like 2400 4800 or 9600 connected to usb tty port on your pc.
Cable with a built in usb to uart ttl converter.
Identificar en un cable de datos usb los cables gnd tierra tx transmisión de datos y rx recepción de datos con la ayuda de un multimetro.
All circuitry integrated into sleek moulded usb plug.
Four connectors are present 5v rx tx and ground.
Deploy and launch the serialsample app.
Drivers for windows and mac are available under preview files.
A cable with a prolific 2303 works fine to access the router as a device eg.
Compatible with legacy software.
The logic level for rx tx is 3 3v.
Allows devices to be powered from the usb port.
If nothing happens try another possible tx candidate.
Please note that this cable does not have an output for supplying power.
Drivers for windows and mac are available under preview files.

This cable is not suitable for programming arduino boards since it doesn t have a reset output.
Cable with built in usb to uart ttl converter.
3 3v signal level for tx rx.
Now that our pc and rpi2 rpi3 or mbm are connected let s setup and deploy the app.
It does not work in host mode to control usb devices.
Inside the big usb plug is a usb serial conversion chip and at the end of the 36 cable are four wire red power black ground white rx into usb port and green tx out of the usb port.
Based on ftdi ft232r.
This cable works well as a debug console cable for raspberry pi.
See if the led will flash when you type.
The gnd tx and rx pins of the module are connected to the gnd rx tx wires of the usb to ttl cable that is connected to our pc.
6 way connector gnd cts vcc tx rx and rts supports data rates up to 3 mbaud allowing a significant performance increase over a standard serial port.
J ai le schéma de la carte mère qui indique quel trou correspond à 3 3v tx rx et gnd.
Again looking from the back of the router.
