  • 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.
