Overview

Introduction

USB TO 4CH RS232/485 is an industrial isolated USB to RS232/485 converter, adopts the original FT4232HL chip, with protection circuits such as built-in power isolation, ADI magnetical isolation, and TVS, and aluminum alloy case design. It is easy to operate with a zero-delay fully automatic transceiver circuit and features fast communication speed, stability, reliability, and security, which is suitable for industrial devices and applications with high communication requirements.

Features

• Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility.
• Supports USB to RS232, USB to RS485.
• Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal.
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, and low power consumption.
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof and ESD protection.
• Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, and improve shockproof performance.
• Built-in 120ohm resistance on RS485 output interfaces, and users can enable it through a DIP switch, easy and flexible.
• 9 LEDs for indicating the power, debugging status, and transceiver status.
• Industrial grade metal case, supports wall-mount and rail-mount installation, solid and beautiful, easy to install.

Driver Installation

• Download the driver file VCP Driver
  
• Double click on CDM212364_Setup.exe and install it.
  
• Click on Extract, and then "NEXT".
  

• Click on I accept this agreement, and then click on "NEXT", and click on "Finish".
  

• After connecting the PC, you can see the usable COM port number in the device manager.
  

Communication Operation

Preparation

• Open the SSCOM software.
  
• Select the corresponding COM port according to the functions (Generally, the identifiable 4 COM port number is Port A to Port D in descending order).
  

• You can check which PORT port is the corresponding COM port through the Device Manager.
  
• Right-click to check the PORT corresponding to the COM8 port.
  

• And you can see the corresponding PORT D to the COM8.
  

RS232 Communication

The following demonstrates communication between RS232 of PORT C and RS232 of PORT D using the product.

Hardware Communication

Software Operation

• Open 2x SSCOM windows.
  
• Respectively select the COM port corresponding to Port C and Port D.
  

• Select the baudrate as 115200, input the characters to be send, select show time and package, click on Open COM.
  

• Both select the 100ms of the SSCOM, and you can see these two windows normally transmit and receive, and the test effect is shown below:
  

RS485 Communication

The following demonstrates communication between RS485 of PORT A and RS485 of PORT B using the product.

Hardware Connection

Software Operation

• Open 2x SSCOM windows.
  
• Respectively select the corresponding COM port to the Port A and Port B.
  

• Select the baudrate as 115200, input the characters to be send, select Show time and package, click on Open COM.
  

• Select one of the SSCOMs at 100ms interval, and you can see that the two ports are sending and receiving normally, and the test result is shown in the figure below:
