Installation of Drivers

Before using the device on Windows, Mac, Linux, or Android systems, ensure you have installed the corresponding drivers provided in the Resources section of the user manual.

Connection Setup

Connect the USB TO RS232/485/TTL converter to your computer using a USB cable. Connect the RS232, RS485, or TTL device to the appropriate port on the converter.

Power Supply

If your connected device requires power, you can switch the VCC pin to provide either 5V or 3.3V power supply. If the device has its own power source, VCC connection is optional.

Data Communication Testing

To test the functionality of the connected device:

• For TTL and RS232 devices, perform a loopback test by shorting RXD and TXD pins.
• For RS485 devices, remove the 120-ohm termination resistor if data issues occur.

Frequently Asked Questions (FAQ)

• It doesn’t work on non-Windows systems, how can I fix it?
  Answer:
  Click to install the corresponding drivers.

• Does it support Linux system?
  Answer:
  Yes, it also supports Win7/8/8.1/10/11, Mac, Linux, Android, and WinC.

• Question:What about the RS485 proximity communication exception, the received data will be more than 0?
  Answer :
  Remove the 120-ohm termination matching resistor for RS485.

• Question:Support USB to RS232,RS485 and TTL at the same time?
  Answer :
  Not supported, only USB to one of the three, USB to RS232, RS485, or TTL. It is not possible to simultaneously convert RS232, RS485, and TTL to USB.

• Question:Does it support RS232,RS485 and TTL interchange?
  Answer :
  Not supported, RS232, RS485 and TTL can not be interchangeable, support USB to RS232, RS485, or TTL.

• Question:How can I confirm that the TTL, RS232 or RS485 function is working?
  Answer :
  TTL and RS232 are full-duplex communication, you can short RXD and TXD to test, RS485 is half-duplex communication, you can test with an external USB to RS485 device, the following figure is the loopback test TTL:

• Question:What is the VCC function?
  Answer :
  VCC is the power supply pin, which can be switched by 5V or 3.3V (50mA) to power the connected device, if the device already has another external power supply, it can be connected without VCC.
