Regards, Mitch. If you plug the device in a look in the logs sudo dmesg , a line typically indicates where the newly found device is attached:. You can try the following things:. On Windows, the port is called COM3 or some other number. You can find the correct port number in the device manager. You need software that sets the baud rate and sends and receives bytes over the serial port.

When using Putty on Windows, turn of software handshaking, which is on by default. In the Serial menu, set Flow control to None. You typically want software that supports arbitrary baud rates and informs you of what is going on. In that regard, screen and gtkterm are insufficient. However, this is an unsupported baud rate and screen silently falls back to Everything seems to be OK, except the baud rate is incorrect.

The cu command at least tells you that the baud rate is unsupported. Everything you type is sent over the serial line, which can make it tricky to exit the program. Use the following key shortcuts to exit:.

Re: USB-Serial Port driver

If you want to connect to an embedded device, the first step is to find the correct pins on the board. Often there is a row of four or five pins with at least ground, Vcc, Rx and Tx. Sometimes the pins are omitted and there are only holes. Often such a connection is labeled as J5 or another number.

The device came with blank pads and I soldered the pins to it. You can see a little table in the silk screening that describes the pins: Tx, Gnd, Vcc, Rx. The pins on the right side are JTAG pins. For similar reasons, debug ports are often on the side of the board.

If you suspect a pin to be a UART line, the first step is to measure the voltage using a multimeter.

First, find a good connection for the common ground and connect the black lead of the multimeter to it. Then measure the voltage on the suspected pins with the red lead. A Tx line will be 3. Keep measuring while rebooting the device. Data is often sent on boot, so we can use this to determine whether data is sent over the line. If data is sent, the voltage will temporarily drop below 3V according to the multimeter. Now you have determined that the line has an acceptable voltage and there is activity on it.

One way to determine this is to use a logic analyzer or oscilloscope to view the electrical signals. In the example below a camera has five holes, initially hidden under a white sticker. This makes it possible to access the UART interface from the outside.

Before connecting to the device, make sure it emits a voltage that is compatible with your bridge. The Rx of the bridge connects to the Tx of the device, and the other way around.

Whether to connect Vcc depends on whether you use an isolated bridge. If your adapter is not isolated, connecting Vcc of your bridge to the device may interfere with the voltage already on the device. If the device gets power from another power supply it already has a certain voltage level on its Vcc pin. However, most bridges can only supply up to mA or so, which is not enough for most devices.

A common way is to try the standard baud rates until the output looks legible. Alternatively, the baud rate can be determined by measuring the length of the shortest pulse. So if we measure the duration of one bit we can determine the baud rate. Alternatively, it is possible with a microcontroller by using input capture to measure pulse widths. I created an autobaud program that works on Arduino Uno and can determine baud rates up to , bps reliably.
