Tripp Lite USB to Serial Adapter User’s Manual Introduction
Introduction
Note: These products comply
fully with USB Specification
version 1.1 and are fully
supported under Windows
98/ME/XP/2000/NT4.
Note: The 16550 is well suited
for applications involving high
data rates and for heavy
multitasking environments. The
larger FIFO allows each
read/write access to the UART
to move more data, resulting in
fewer interrupts and less
processor time spent servicing
the UART.
This Users Manual describes how to setup and install your Tripp Lite
USB to Serial Adapter.
The Tripp Lite U209-004 provides four independent RS-232 serial
interfaces to the host PC via the Universal Serial Bus (USB) port.
The following table details the port and connection configuration for
the USB to Serial Adapter device.
Table 1 - Device port and connection
Device Ports Connection
U209-004 4 RS-232
Each adapter comes standard with 16550 Universal Asynchronous
Receiver/Transmitters (UARTs) containing 16-byte First In First Out
(FIFO) storage devices. These FIFOs, in conjunction with the USB
micro controller FIFOs, help to relieve the CPU of excessive
interrupts by buffering received and transmitted data. This
configuration allows each channel to obtain data rates up to 460.8
kbps. The adapters are USB bus-powered; therefore no external
power supply is required.
The USB to Serial Adapter product is a Plug-and-Play device and
requires no hardware configuration. Your computer's BIOS or
operating system automatically configures the ports when you install
the device.
System requirements
Note: The Tripp Lite USB to
Serial Adapter requires one

this registry.
The USB to Serial Adapter includes an INF configuration file to allow
easy configuration in the Windows environment. Windows uses the
INF file to determine the system resources required by the adapter,
searches for available resources to fill the board's requirements, and
then updates the hardware registry with an entry that allocates these
resources.
The USB to Serial Adapter also includes Windows device drivers that
enable the adapter’s serial ports to appear to Windows as standard
COM ports.

RS-232 serial connections
The Tripp Lite USB to Serial Adapter comes with standard male DB9 connectors. The figure below shows the pin designations.
Figure 37 - RS-232 DB-9 pin designations
RS-232-C devices are classified by their function as either Data
Terminal Equipment (DTE) or Data Communication Equipment
(DCE).
Figure 38 - Use of DTEs and DCEs in a communication link
Figure 38 illustrates role of
DTE and DCE devices in a
communications link.
Note: A DTE devices is the
communication source. A DCE
device provides a communication
channel between two DTE-type
devices.
Note: In many applications,
DCEs are unnecessary. This
allows you to use a null modem
cable (modem eliminator cable)
to directly connect two DTEtype devices.
Tripp Lite’s USB to Serial Adapters are DTE devices that connect to
peripheral equipment through a male DB-9 connector. The following
table lists the serial port connector definitions.

Before testing your serial ports, you must first hook up a loopback. A
loopback connects the output signal (TxD) to the input signal (RxD) in
a single serial port connector to make it seem like there are two ports
