Overview

USB TO 4CH RS232 is an industrial USB to RS232 isolated converter, featuring the original FT4232HL. It has onboard protection circuits such as built-in power isolation, ADI magnetical isolation and TVS diode. With an aluminum alloy case, USB TO 4CH RS232 offers simple operation, zero-delay automatic transmission and reception conversion, and boasts characteristics such as fast, stable, reliable and safe communication, suitable for industrial control applications with various communication requirements.

Features

• Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility.
• Supports USB to 4-ch isolated RS232, convenient for expanding multiple RS232 industrial serial devices.
• Onboard unibody power supply isolation, provides stable isolated voltage.
• Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference and low power consumption.
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection.
• Onboard self-recovery fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improve shock proof performance.
• Onboard power supply screw terminal, allows 5V ~ 36V DC wide range input.
• 9 LEDs for indicating the power and transceiver status.
• Aluminum alloy enclosure with sand blasting and anodic oxidation, solid and durable.

Driver Installation

USB 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 finally click on "Finish".
  

• After connecting to 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. (Normally, the identifiable 4 COM port number is Port A to Port D in descending order.)
  

USB TO 4CH RS232 - PORT	Communication Mode
PORT A	RS232
PORT B	RS232
PORT C	RS232
PORT D	RS232

• You can check which 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 A and RS232 of PORT B using the product.

Hardware Communication

USB TO 4CH RS232 - PORT A	USB TO 4CH RS232 - PORT B
PORT A - RXD	PORT B - TXD
PORT A - TXD	PORT B - RXD
PORT A - GND	PORT B - GND

Software Operation

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

• Select the baudrate as 115200, input the characters to be sent, select Show time and packet, and 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:

FAQ

Question:Only 1 COM port can be recognized when the device is connected to the computer (if the computer normally recognizes 4 COM ports, please do not do the following).

 Answer:

• It may be caused by a corrupt registry, and you can address it by performing the following steps:

1. Download the registry-related demo and run it.


2. If there is a pop-up window, please allow the demo to run.
3. Download Configuration Software to select CDMUninstaller.exe and open. (If CDMUninstaller.exe can not successfully run, please use CDMuninstallerGUI.exe.)

4. Configure and execute (please erase the value of "Product ID" -> Click "Add" -> ③ -> Click "Remove Devices" -> OK)

5. If the CDMUninstaller.exe can not successfully run (as the following shows), please use CDMuninstallerGUI.exe.
