Introduction
The ES-U-xxxx-x family of converters provide a quick and simple way to add serial communication ports
to your computer. They connect to a single USB port on your computer to instantly provide up to 32
serial ports. They take advantage of the plug-and-play and hot-plug features of the USB bus to make it
easier than ever to add communication ports to your system.
Installation is easy. There are no IRQ & COM port conflicts as the port doesn't require any additional IRQ,
DMA or memory resources on the system. Each RS-232 or RS-422/RS-485 port functions as a native
Windows COM port and is compatible with Windows serial communication applications.
The ES-U-xxxx-x converters provide instant connectivity to RS-232 or RS-422/RS-485 compatible
devices, including factory automation equipment, multi-drop data collection devices, barcode readers,
time clocks, point of sale, scales, data entry terminals and a variety of other devices in industrial
environments.
