How to Install the USB2 Serial Driver?
If the drivers have been installed properly, your adapter should appear as /dev/ttyUSB0 in the System Properties-Device Manager screen (reach this page by starting, setting, and controlling Panel then System Properties Hardware then Device Manager). To check this information simply repeat steps 1 through 7 again until complete.

The USB serial core registers one struct usb_serial_port structure per port on a device, with probe() handling opening it for use by the tty layer. Module count decrementation occurs so the driver cannot unload while communicating with a USB device.
Supports RS-232:
Early personal computers relied heavily on RS-232 ports as their main connection point to external hardware. As these were replaced with USB, their functionality remains similar; only with smaller connectors. USB devices operate using a different protocol and share a data bus, so to transfer information between it and computer programs using it, a software driver must be installed first.
Drivers for USB devices come in two varieties: virtual COM port (VCP) and direct. VCP drivers act like serial ports, allowing software programs to communicate with USB devices as though it were connected through an RS-232 serial line connection – compatible with most operating systems. Direct drivers allow software programs direct access to USB devices through direct drivers.
VCP drivers for Linux provide an easy way to add USB-to-serial conversion. HyperTerminal works seamlessly with this driver, making it suitable for older laptops and PCs without onboard RS-232 ports.
The Linux tty core provides the kernel with a way to identify which USB-to-serial device it is dealing with, through viewing information in /sys/devices/PCI/0000:00/0/usb1/1-1.1:0/ and its subdirectories such as ttyUSB0/, ttyUSB1/, ttyUSB2/ ttyUSB3/ and ttyUSB4/ directories and files that display dev, name power consumption, module count etc.
Supports RS-422:
RS-422 is an industrial-grade serial data transmission system using one pair of wires without needing handshaking; optical isolation and surge protection are provided as additional layers of protection for data. A USB-to-RS-422 converter can convert USB data signals into an RS-422 signal; these adapters come equipped with various ports and operating modes making them suitable for many different uses.
These USB to RS-422/485 converters are designed for ease of use and compatibility with all Windows operating systems, making installation simple. Each model comes equipped with a USB cable and software drivers to facilitate set-up, once which the device will appear as an ordinary COM port in Windows – perfect for connecting barcode readers, time clocks, scales, or other industrial equipment to your computer!
Inside this unit is a 10×2 header block that allows users to jump for different modes of operation, including TxD/RxD termination, CTS handshaking, and 120 Ohm RS-422 termination. Simply open either plastic or metal covers to configure jumpers as desired and set jumpers accordingly.
Supports RS-485:
A USB-to-serial adapter is a device that turns a computer’s USB port into a standard RS-232, RS-422, or RS-485 serial port for legacy serial devices with DB9 or DB25 connectors and screw terminals. Available from manufacturers such as FTDI and Silicon Labs, some plug-and-play models require drivers for installation; others are plug-and-play only.
USB-485-1 USB to RS-485 converter is a 10-by-2 (20 pin) header block configured with jumpers for either RS-485 or RS-422 mode, by opening up plastic or metal covers and setting jumpers as required by your application. Additionally, the unit supports 120-ohm termination of data transmission lines and CTS/RTS handshaking functionality.
This product utilizes a high-quality processor chip from Prolific Technology and RS-485 conversion circuitry for maximum compatibility and support of various operating systems and the majority of COM ports in your PC. Furthermore, this device supports hot swapping and retention; automatically reassigning values when cables are unplugged or the system rebooted automatically reassigning them with similar values when disconnecting and reconnecting cables as well.
This RS-485 to USB converter is ideal for industrial, commercial, and general office computer applications. Powered by its USB port and equipped with a red power indicator that lights when the adapter is connected to power sources, this converter supports up to 256 RS-485 devices at once and features selectable 120-ohm terminators for added reliability.
Supports RS-X:
USB offers numerous advantages over older serial and parallel port connectors, including smaller connectors and higher data throughput. However, unlike its traditional RS-232 counterparts, USB devices communicate through a shared data bus that requires a software driver to manage data flow into and out of computer programs.
Once a USB to RS-232 adapter is connected to a computer, its software driver recognizes it and creates a virtual COM port in Device Manager or /dev/serial (Linux/MacOS), enabling programs to access it just like they would any RS-232-based COM port.
These USB to RS-232 converters support both high and low baud rates, making them suitable for many applications such as modems, ISDN terminal adapters, and serial ports on mobile phones or PDAs. Their LED indicators make it easy to see what is happening over a serial line.
These USB to RS232 converters are an ideal way of upgrading legacy systems that feature UART DB9 connectors to USB 2.0 connectivity without redesigning their PCBs. They feature a mini-B connector powered by FTDI FT2232D chips which fits within an industry standard DB9 footprint, eliminating the need for external power adapters.
