Overview
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,
which means more peripheral devices can be attached to the
system.
The UC-232A USB-to-Serial Converter 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.
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 up to 230 Kbps. It makes
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.
Note: The UC-232A does not support devices, such as serial
mice, that require an IRQ number or IO Address.
