Konfigurazioa

1. Gidariaren instalazioa:

   For most modern operating systems (Windows 10, Mac OS-X, Linux), drivers for the FTDI FT232RL chip are often installed automatically upon connecting the device. If automatic installation fails, or for older operating systems, download the appropriate VCP (Virtual COM Port) drivers from the official FTDI webgunea (ftdichip.com/drivers/vcp-drivers/). Follow the installation instructions provided by FTDI.

2. Konektatu ordenagailura:

   Plug the USB end of the adapter into an available USB port on your computer. The Power LED on the adapter should illuminate, indicating it is receiving power.
3. Select TTL Voltage Maila:

   Locate the 3.3V/5V switch on the adapter. Set the switch to the desired voltage level (3.3V or 5V) to match the logic level of the device you intend to connect. Ensure this is set correctly before connecting to your target device to prevent damage.

4. Identify COM Port:

   After driver installation, the adapter will appear as a Virtual COM Port (VCP) in your computer's Device Manager (Windows) or equivalent system information utility (Mac/Linux). Note the assigned COM port number for use with serial communication software.

Funtzionamendu-argibideak

The YELUFT USB to TTL Adapter is designed for various serial communication tasks. Below are general guidelines for its operation.

1. Pin konexioak:

   Connect the adapter's pins to your target device according to the following standard:

   • TXD (Transmit Data): Connect to the RXD (Receive Data) pin of your target device.
   • RXD (Receive Data): Connect to the TXD (Transmit Data) pin of your target device.
   • GND (lurra): Connect to the GND (Ground) pin of your target device.
   • VCC (Voltage Common Collector): Provides the selected 3.3V or 5V power output. Connect to the VCC/power input of your target device if it requires power from the adapter. Caution: Ensure the voltage matches your device's requirements.
   • RTS (Request To Send) / CTS (Clear To Send): These are hardware flow control pins. Use them if your application requires hardware flow control; otherwise, they can be left unconnected.

2. Serial Communication Software:

   Use a serial terminal program (e.g., PuTTY, Tera Term, Arduino IDE Serial Monitor, minicom on Linux) to communicate with your device. Configure the software with the correct COM port, baud rate, data bits, parity, and stop bits as required by your target device.
3. LED adierazleak:
   • Power LED: Illuminates when the adapter is connected to a USB port and receiving power.
   • TXD LEDa: Flashes when data is being transmitted from the computer via the adapter.
   • RXD LEDa: Flashes when data is being received by the computer via the adapter.

4. Aplikazio tipikoak:

   This adapter is suitable for:

   • USB-to-serial (RS232/RS422/RS485) conversion (with external level shifters if needed).
   • EEPROM programming.
   • Vendor ID customization.
   • Router/Mprog3.5 recovery.
   • GPS module interfacing.
   • Firmware updates for various devices (e.g., hard drives, transmitters).
   • Set-top box communication.
   • Microcontroller programming (Arduino, ESP32, etc.).

Mantentzea

• Biltegiratzea: Store the adapter in a dry, cool environment, away from direct sunlight and extreme temperatures.
• Garbiketa: Erabili zapi leun eta lehor bat egokitzailea garbitzeko. Saihestu garbitzaile likidoak edo disolbatzaileak erabiltzea.
• Manipulazioa: Handle the adapter by its edges to avoid touching the electronic components. Do not bend or apply excessive force to the pins or the USB connector.
• Kableen kudeaketa: Ensure connected cables are not under tension to prevent damage to the adapter's pins or the USB port.

Arazoak konpontzea

• Egokitzailea ez da ezagutzen:

  Ensure the adapter is fully plugged into the USB port. Check Device Manager (Windows) or system information for the presence of the FTDI device. If not found, reinstall the FTDI VCP drivers manually from the official FTDI webgunea.

• No Data Transmission/Reception (TXD/RXD LEDs not flashing):
  • Verify pin connections: TXD to RXD, RXD to TXD, and GND to GND.
  • Confirm the correct COM port is selected in your serial communication software.
  • Check that the baud rate, data bits, parity, and stop bits settings in your software match those of your target device.
  • Ensure the target device is powered on and functioning correctly.

• Device Not Responding / Damage:
  • Verify the 3.3V/5V switch is set to the correct voltage level for your target device. Supplying incorrect voltage can damage the target device or the adapter.
  • Ensure the VCC pin is only connected if your target device requires power from the adapter and can handle the selected voltage.
  • Avoid short circuits between pins.
• Etengabeko konexioa:

  Try a different USB port on your computer. Ensure all cable connections are secure. Avoid using excessively long or low-quality USB extension cables.
