• USB to TTL: Connect the adapter's TX, RX, and GND pins to the corresponding RX, TX, and GND pins of your TTL device.
• USB to RS232: Use the 232T, 232R, and GND pins for RS232 communication.
• USB to RS485: Connect the A and B pins for RS485 communication.
• TTL to RS232/RS485, 232 to 485: For these conversions, ensure the adapter receives power from the USB port or an external VCC/GND pin. Connect the respective TX/RX or A/B lines between the devices. Note that for direct TTL-232/485 or 232-485 conversions, the USB connection is primarily for power, not direct data interaction with the PC.

7. Fehlerbehebung

If you encounter issues while using the WitMotion 6-in-1 Serial Adapter, consider the following troubleshooting steps:

• Driver Not Recognized: Ensure the CP2102 driver is correctly installed. Try reinstalling the driver or connecting the adapter to a different USB port.
• Keine Datenübertragung/-empfang:
  • Verify that the mode selection switch is set to the correct protocol (TTL, RS232, or RS485).
  • Check all wiring connections for correctness and ensure they are secure.
  • Confirm that the baud rate settings on both the adapter and your target device match.
  • Observe the RX/TX LEDs. If they are not flashing during data transfer, there might be a connection or configuration issue.
• Probleme mit der Stromversorgung: Ensure the adapter is receiving sufficient power from the USB port. The yellow USB LED should be illuminated.
• Softwarekonfiguration: Double-check your serial terminal software or development environment settings (COM port, baud rate, data bits, parity, stop bits).
