Overview

USB TO RS232/485 is a USB to RS232/485 non-isolated serial port converter, featuring the original FT232RNL chip for improved stability and compatibility. It comes with a built-in self-recovering fuse, TVS protection circuit, etc. USB TO RS232/485 offers simple operation, zero-delay automatic transmission and reception conversion, and boasts characteristics such as fast, stable, reliable and safe communication.

Features

• Onboard Original FT232RNL chip. Fast communication, stable and reliable, better compatibility.
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic.
• Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shockproof performance.
• Onboard RS232/485 communication switching circuit, configured by switch.
• Onboard 120R terminal resistor on the RS485 interface, enabled/disabled via switch.
• 3x LEDs for indicating the power and transceiver status.
• ABS case design, small in size, easy to use, portable and cost-effective.

Hardware Test

Test environment: PC (Windows)
Required accessories:

• USB TO RS232/485 x 2pcs
• USB-A male-to-female cable x 1 (or directly connect to the USB port of the computer)
• Wires

RS232 Test

• Connect the RS232 interface of the USB TO RS232/485 module to the RS232 interface, that is, RXD and TXD are connected in a staggered manner, GND and GND are connected, and the toggle switch on top of the module is switched to RS232, and the connection diagram is referenced as follows:

• Open two SSCOM windows and the corresponding COM port numbers.

• Select the baud rate as 115200, input the characters to be sent, check show time and package, and click on Open COM:

• Set the two SSCOM windows sending at 100ms intervals, and then you can see the 2 Windows send and receive data normally, the effect as shown below:

RS485 Test

• Connect the RS485 connector of the USB TO RS232/485 module, that is, A+ --> A+, B- --> B-, GND --> GND, and switch the toggle switch on it to RS485, the connection diagram is referenced below:

• Open two SSCOM windows on the PC and the corresponding COM ports:

• Select the baud rate as 115200, input the characters to be sent, check show time and package, and Open COM.

• Select one SSCOM, send it at 100ms intervals, and then you can the 2 Windows send and receive data as shown below:
