Description
  • All use original chips.
  • Industrial-grade protection: TVS transient suppression protection, static ESD protection, surge protection, AB signal line protection.
  • Short-circuit and power short-circuit protection (short-circuits won’t cause damage).
  • Transmission distance can reach up to 1200 meters (tested at 9600 BPS).
  • Supports baud rate of 921600, much higher than 115200, with even higher baud rates when used in pairs.
  • Supports hot swapping across multiple systems, including WIN98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/VISTA/LINUX/MACOSX. The USB interface supports hot swapping.
  • Automatic data transmission direction detection and control, no need for any handshake signals (like RTS, DTR, etc.). Mode switching can be achieved without jumper settings, ensuring compatibility with existing communication software and interface hardware.
  • Equipped with TXD and RXD indicator lights.

Product Port Marking and Wiring:
Wiring Instructions: When using the product, turn it upside down, and order the terminals from left to right.
For the USB interface, connect directly to the computer’s USB port when in use.

485 Bus Interface:

  • 5-pin terminal A -- 485 device A (D+)
  • 5-pin terminal B -- 485 device B (D-)
  • 5-pin terminal GND -- 485 device GND

232 Bus Interface:

  • 5-pin terminal RXD -- 232 device TXD
  • 5-pin terminal TXD -- 232 device RXD
  • 5-pin terminal GND -- 232 device GND

Self-Loopback Test Function:
The self-loopback test can verify the functionality of the product. The method is as follows:

USB to 232 Self-Loopback Test:
Connect the module’s TXD and RXD using DuPont wires, then insert the module into the computer. Use a serial port debugging tool to send data and check if the corresponding data is returned. If the sent data is received, it proves that the module is functioning properly.

USB to 485 Self-Loopback Test:

(This mode requires testing with other 485 devices, such as using two 2-in-1 modules.)
Download and open the debugging software, and open two instances of the software interface. Plug the two converters into the computer, then open the device manager to view the virtual COM port numbers. Set the COM port numbers in the corresponding locations in the debugging software. Connect the two converters by matching A to A and B to B, and send data between them.
