Quick Overview

USB Four Port Serial DB-9 RS-232 Adapters with Prolific Chipset

The CG-4X232 equips your system with four RS-232 serial ports while taking up only one USB port! Connecting devices like serial modems, GPS receivers, serial printers, and PDAs has never been easier.

Got more serial peripherals than you do ports? Don’t sweat it; we have the solution to your problem! The CG-4X232 is perfect for laptop and desktop users. It is light-weight and compact, so you can take it with you when you’re on the go. This device is also fully plug and play compatible, which provides you with the flexibility of hot swapping your serial devices without rebooting. Expand your PC or Notebook computer by using this USB to serial RS232 Converter. Gain more control over your current serial devices through your USB technology. Small and convenient, the USB serial RS232 2-port converter can enable and expand your peripheral usage many times over.

How the USB to Serial dual port RS-232 converter works:
The USB Serial Quad-Port converter with Prolific USB Technology allows the use and operation of two serial devices via USB control simultaneously. The USB serial dual-port converter is self powered through the USB Port that it's connected to. The USB serial dual-port converter adds 4 additional RS-232 serial ports to you PC or Laptop as seen in the images above.

To install the device on your computer, first insert the converter driver CD into your CD-ROM drive and install the drivers. After the drivers have been installed, connect the USB to RS-232 serial converter to your USB Port. The new hardware wizard in Windows after connecting the USB serial rs232 converter to the USB port should automatically recognize the new hardware. You will see the new hardware wizard several times as it must install the driver for each of the RS-232 serial ports to function properly with the USB port. You will see that the prolific USB serial bridge drivers will be installed for each new piece of hardware found.

NOTE: If for some reason the USB to serial converter is not recognized after connection, try rebooting your PC or laptop or manually adding the hardware through Add New Hardware Wizard.

Customer Reviews

  1. Recommended Adapter! Review by CalgaryBen

    I had a need for a quad-port USB to RS-232 adapter, and this fit the bill perfectly. My requirement was that it used the Prolific chipset, since my OS has PL2303 drivers. My OS also has FTDI FT232 drivers, but most current/modern 2- or 4-port RS-232 adapters use the FT2232 or FT4232 chipsets (basically to combine a USB hub and 2- or 4- FT232 chips into a single ASIC), which I currently do not have kernel objects for (I'm running ftdi_sio 1.4.3, and cannot rebuild 1.5.0 kernel objects which do have FT2232 and FT4232 chipset support).

    This device fulfills a very specific need. Most users may find the FTDI devices suitable, in which case that is probably the way to go (lower power consumption, more robust architecture/design such as injection-molded RS-232 ends, etc.). This device will draw about 3x the current of a FT4232 based device (~41 mA versus about 15 mA).

    My only concern with this device is that the plastic housing for RS-232 ends has a clear "window" which gives the PCB visibility. This window was likely implemented for the FTDI version of the adapter, which has power-indicating LEDs. For the Prolific implementation, the window is useless and represents a possible weak spot (exerting a bit of force on this wndow can cause it to crack/break or become dislodged).

    Other than that, I will likely order more of this device, which will be used in some industrial automotive applications. (Posted on 7/3/2013)
