Why is RS232 not working?

Why is RS232 not working?

The most common cause of serial port communication problems is incorrect communication parameter settings. To operate correctly it is essential that both devices are set up with the same communication parameters, which includes baud rate, parity, number of data bits, and number of stop bits.

Does RS232 need driver?

The Evolution from RS-232 to USB The connector was reduced from a 25-pin connector to a 9-pin connector, but RS-232 ports remained present on every computer for many years. To handle the packets and move data in and out of the program accessing the USB device, a software driver is needed.

How do I log into Arduino serial data?

Enter the COM port (e.g. COM12) in the “Serial line” field, then click the “Serial” button. On the left-hand side, select ‘Logging’, then select ‘Printable output’, and maybe select ‘Always’. Overwrite it if that is what you want. Click ‘Browse’ and look for a place and file name where you can save the file you logged.

How do I fix COM ports?


  1. Go to Windows Device manager > Multi-port serial adapters.
  2. Select the adapter and right click to open the menu.
  3. Click on the Properties link.
  4. Open the Ports Configuration tab.
  5. Click on the Port Setting button.
  6. Select the Port Number and click OK.
  7. Click OK to apply the changes.

How do I fix a serial port problem?

Go to Device Manager > Ports (COM & LPT) > mbed Serial Port, then right-click and select “properties”. Choose “Port Settings” Tab, and click “Advanced” Under “COM Port Number”, try selecting a different COM port. Unplug and replug the mbed to reload the driver – if the problem persists, try another COM port.

Can you convert RS-232 to USB?

Yes, a RS232 to USB converter does have a full-blown UART circuit built-in. As any standard UART, it does have Rx, Tx, and flow control pins. As any UART, it must be properly configured to be able to communicate with the “partner” at the other end of UART link. To do so, the UART circuit is “bridged” to USB interface.

How do I convert Arduino data to CSV?

How To Save Data from Arduino To A . csv File Using Processing

  1. Introduction.
  2. First, Download and Install the following:
  3. Step 1: Read Data, Send to Processing via Serial Port.
  4. Step 2: Use Processing to Receive Data from Arduino, Write data to a Table, and Save Table to a .csv.
  5. Additional Resources.

How does Arduino store sensor data?

There are a number of options for recording sensor data.

  1. If connected to a computer, the data can be saved by reading the serial output and storing that in a file.
  2. If there is an SD card connected to the Arduino, the data can be saved directly to the SD card.

Can you convert RS232 to USB?

How do I connect two devices to RS232?

All you do is pass the wires between them male one end, female on the other, connecting pin X on the DTE to pin X on the DCE side. Provided, the DTE and DCE agree on transmission speed, you are done.

What is RS232 data logger?

RS232 Logger will display how many bytes are stored in the log file and all data logged from the serial port in a comprehensive way. RS232 Data Logger is a handy tool for testing serial port communication. As all data is saved into the log file, it can be analyzed later for any errors in commands or data.

How to monitor RS232 serial communications?

In order to monitor and analyze serial communications between a computer and a COM port device, you can rely on a dedicated software – serial data logger which will read and record RS232 data to a text file for its further analysis.

What is a serial port data logger?

A serial port data logger is an essential tool when working with serial communication applications and hardware. Logging can be done via RS232 data logger software or specialized hardware allowing serial traffic to be saved to a file for later analysis.

What is rslogger module?

RSLogger Module is a hardware solution that is popular with many users. It is a reliable data logger and analyzer that can be used to transmit data over WiFi or Ethernet. The device can be used with virtual COM interfaces and uses external USB Mass Storage support to provide unlimited storage capacity.
