Introduction
This User’s Manual describes how to setup and install your USB-to-
Serial Adapter.
The QSU2-100 and ESU2-100, respectively, provide four and eight
independent RS-232 serial interfaces to the host PC via the Universal
Serial Bus (USB) port.
The QSU2-400 and ESU2-400, respectively, provide four and eight
independent asynchronous serial interfaces via the USB port. Each of
these interfaces can be used as desired for RS-232, RS-422 or RS-485
communications.

Each adapter uses high-speed UARTs and deep FIFOs, allowing each
channel to obtain data rates up to 921.6 kbps. The adapters are
powered over their USB connection (bus-powered), eliminating the
need for an external power supply. The adapters are Plug-and-Play
devices and require no hardware configuration.
System Requirements
The USB-to-Serial adapters are supported under the Windows 2000/XP
(and later) and Linux operating systems. One USB port is required to
connect the adapter to your computer. You can use either a built-in
USB port or an add-in USB host adapter. We recommend the use of a
USB 2.0 port for best performance. Contact our sales department for
details on current software offerings.
Note: These products comply
fully with USB Specification
version 2.0. They will also
operate over slower USB 1.1
connections at a slightly
reduced performance level.
Note: The “-400” designation
indicates an “MEI” device.
MEI is an acronym for
“Multiple Electrical Interface.”
The interface is software-
selectable for each serial port.

Features
Multiple Electrical Interface (MEI)
MEI adapters (model numbers ending with “-400”) are shipped with a
factory default of all serial ports set for RS-232 connections. Each
port can be individually configured for RS-232, RS-422/485 full-
duplex, or RS-422-485 half-duplex operation.
Understanding the LEDs
The LEDs inform you of the configuration of the adapter’s serial
ports. Each serial port has one associated LED located on the back
panel to the right of the port’s DB-9 connector. The following table
lists the possible states of the LEDs and their meaning.

Red
Port is configured for RS-232.
Green
Port is configured for RS-422/485.
Installing the USB-to-Serial Adapter
