Overview
Windows Installation
Universal Serial Bus (USB) port technology has emerged in
response to the proliferation of external peripheral devices
(scanners, digital cameras, removable drives, etc.), that are
increasingly being connected to the latest generation of
computers. It is faster than traditional bus ports and, since it
does not require any IRQs, the problem of IRQ conflict is
eliminated so more devices can be attached to the system.
Installing the Adapter
The UC-232A USB Serial adapter provides an external
plug-and-play RS-232 serial connection for computers,
notebooks, laptops, and handheld computing devices that
support the USB specification. It comes with a standard DB-9
Male connector for the peripherals to plug into, and an attached
35 cm USB cable with a type A plug for connecting to the
computer’s USB port, or to a USB hub.
1. With the computer booted up, plug the UC-232A into the
computer’s USB port; the New Hardware Wizard appears;
click Next to continue.
2. In the dialog box that comes up, leave the default choice
(Search for the best drivers for your device); click Next to
continue.
3. In the dialog box that comes up, first put the distribution disk
into your CDROM drive; choose Specify a Location; Browse
to the folder on the disk that corresponds to your version of
Windows; Click Next to continue.
4. In the Ready to install... dialog box that comes up, click Next
to continue. Files are now copied to your hard disk.
The UC-232A provides mobile phones, PDAs, digital cameras,
modems and ISDN terminal adapters with high quality serial
connections at a data transfer rate of over 500 Kbps. It make the
USB interface transparent to the peripherals, allowing them to
easily interface with the USB, eliminating the setup hassle found
with traditional serial port connections. As a USB Specification
compliant device, the UC-232A also supports energy-saving
suspend and resume operations.
5. After the driver files have been copied to the hard disk, a
dialog box appears to tell you that the installation has
finished. Click Finish. Windows now finishes up the
installation.
Note: The UC-232A installs as a virtual port driver on Com3. As
such it does not support devices, such as serial mice, that
require an IRQ number or IO Address.
1. Open the System folder: (My Computer à Control Panel à
System)

Uninstalling the Driver
1. With the computer booted up, and the UC-232A adapter
already plugged into the computer’s USB port, plug the
peripheral into the UC-232A; then turn the peripheral On.
2. Follow the Installation Wizard’s on-screen instructions to
complete the installation.
Note: 1. This procedure only occurs the first time you connect
up your peripheral. If your peripheral was previously
connected and configured for the RS-232 (COM) port,
after you perform the Adapter Installation and click
Finish (see previous page), the driver will detect it and
install it automatically.
