Introduction
The UPort 1100 Series of USB-to-serial adaptors provide an easy way to add COM ports to your
computer. The UPort 1110 provides one RS-232 port, the UPort 1130 provides one
RS-422/RS-485 port, and the UPort 1150 and UPort 1150I each provide one RS-232/422/485 port.
As a plug and play USB device, the adaptors are perfect for mobile, instrumentation, and point-of
sale applications.

UPort 1100 Series User’s Manual
Introduction
Overview
The UPort 1110, UPort 1130, and UPort 1150/1150I are part of Moxa’s UPort line of
USB-to-serial adaptors. The UPort line provides a range of easy-to-use solutions for adding COM
ports through a PC’s USB port. Simply install the drivers, connect the UPort to your computer,
plug in your serial devices, and you’re ready to go. Programming is not required, and you do not
need to worry about IRQs, configuring a board, power requirements, or connection schemes.
The UPort 1100 series provides single COM port expansion. The UPort 1110 adds one RS-232
port to your computer, which is the same type of COM port that is built into most PC
motherboards. The UPort 1130 adds one port that is configurable for RS-422, 2-wire RS-485, and
4-wire RS-485 modes. The UPort 1150/1150I adds one RS-232, RS-422, 2 wire RS-485, or 4 wire
RS-485 port to your computer. All of these models can operate at speeds of up to 12 Mbps, which
is much faster than the current maximum serial transfer rate.
The adaptor is bus-powered, so no external power supply is required.

Adjustable Pull High/low, Terminator Resistors for the RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection
of serial signals. When using termination resistors, it is important to set the pull high/low resistors
correctly so that the electrical signal is not corrupted. The UPort uses DIP switches to set the pull
high/low resistor values for each serial port.
To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in
the OFF position. This is the default setting.
To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in
the ON position.

ATTENTION
Do not use the 1 KΩ setting on the UPort when using the RS-232 interface. Doing so will
degrade the RS-232 signals and shorten the maximum allowed communication distance.

Installation and Configuration
Installation of the adaptor is a simple process. First install the driver, then plug the adaptor into a
USB port. When the adaptor is plugged in, Windows will load the correct drivers for the adaptor
and the new COM port. In this chapter, basic installation and configuration procedures are
explained. Although the installation screens will be for Windows 2000, the procedures are
essentially the same for Windows 98 and later versions.
The following topics are covered in this chapter:

Configuring the COM Port
After the driver and hardware have been successfully installed, the new COM port will have a
COM number and can be accessed and controlled just like your PC’s built-in COM ports. If you
need to change the baud rate, parity, or other COM port settings, you may use your serial
communication application to make those changes. You may also go to Device Manager and
right-click the MOXA USB Serial Port, which will be listed under Ports along with your PC’s
built-in COM ports. In the context menu that pops up, you may select Properties in order to
modify the COM port settings.

ATTENTION
Before modifying these settings, make sure that you have closed any applications that may be
accessing the COM port, such as HyperTerminal.
You may change the Port Number and enable or disable the Fast Flush function. For the UPort
1130, you may also select between RS-422, 2-wire RS-485, and 4-wire RS-485 modes. Please note
that Auto Enumerating COM Number and Set the change to all ports are not available for this
model of UPort.
* The UPort 1100 only supports RS-232. For this reason, when using the UPort 1100, the Interface
drop-down box will be inactive.
*The UPort 1150/1150I support RS-232, RS-422, 2-wire RS-485, and 4-wire RS-485. The default
setting is RS-232.
The Fast Flush function is specifically designed to handle Win32 PurgeComm() function calls and
is enabled by default. When Fast Flush is enabled, the driver will automatically clear the local
buffer when it receives a PurgeComm() command. When Fast Flush is disabled, the driver will
repeatedly query the adaptor until it verifies that there is no more data in the buffer. Disabling this
function can cause lower throughput for applications that use PurgeComm() heavily.

Removing the Adaptor
The adaptor is a plug and play device. No special procedures are required to remove the adaptor;
you may simply pull the adaptor out of the USB port. You should verify that no data is being
transmitted before removing the adaptor.
Removing the adaptor does not remove the drivers. The drivers remain in place so that the adaptor
can be automatically detected and installed if it is pluged back into the USB port.
The adaptor can also be uninstalled through the Device Manager, the same as other Windows
devices. Right-click the adaptor, which will be found under Multi-port serial adaptors, then
select Uninstall from the context menu.
Uninstalling the Driver
The UPort driver may be removed through Add/Remove Programs in the Windows Control Panel.
