Configuring Your Serial Device
The following instructions provide a basic overview of how to configure
your software to use your Keyspan serial port. For specific instructions on
how to operate your serial device, refer to that device’s user manual.
1. To configure your serial device for use with the USA-49WG, you must
connect it to an available DB9 port on the unit via a serial cable
appropriate for your device.
2. Prior to using your serial device with a Keyspan serial port, you must
first tell your serial device’s software which Keyspan serial port your
device is connected to. Most serial devices have software that allows
you to select or configure which port the device is connected to.
Please refer to your serial device’s documentation on how to set the
serial port settings.

Configuring Your Serial Device
3. After you have determined where to select or configure your serial
device’s serial port settings, navigate to that screen. Here you will
either have to select your device from a list of connected devices,
enter in the port number your device is connected to, or some
combination of both. The port number for your device can be found
using the Keyspan Serial Assistant. Locate and open the Keyspan
Serial Assistant via the Start > Programs section in Windows, or the
Applications section in Mac. In Windows, locate the USA-49WG port
that your device is connected to, and use the COM port that has been
assigned to it. For Mac, locate the USA-49WG port that your device
is connected to. The port number will be the last number in the port
name (See page 6 in Keyspan Serial Assistant section for details).
4. Once you’ve set your serial device’s software to use the Keyspan
serial port, you are ready to start using your device.

Keyspan Serial Assistant
Besides the required drivers, the Keyspan USB Serial Adapter software
installs an application called Keyspan Serial Assistant. This application is
used to:
• Show the names of the installed serial ports
• Determine the status of the adapter software and hardware
• Assist in problem solving
Launching the Keyspan Serial Assistant
To launch the Keyspan Serial Assistant, locate and open Keyspan Serial
Assistant via the Start > Programs menu in Windows or the Applications
folder in Mac. Upon opening, the Keyspan Serial Assistant screen will
appear. The name of the Keyspan serial adapter will appear as USA-
49WG-1. The -1 at the end of the model name is to signify that this is
the latest hardware version of the USA-49WG adapter. Towards the left
of the USA-49WG-1 will be a +/- icon in the Windows assistant, and an
arrow icon in the Mac assistant. Click on this icon to expand or collapse
the list of serial ports.

The following is a description of all the relevant text boxes and menus
found in the Keyspan Serial Assistant. You can also obtain this
information by turning on the Enable Tool Tips check box in the Help tab
in the Assistant window.
Adapter Status Tab
The Adapter Status tab, shown in the previous section of this manual,
displays the status of your Keyspan adapter. Specifically, it shows the
COM port number (COM1, COM2, etc.) and the COM port status (IDLE
or BUSY). If you have several Keyspan adapters of the same type, they
will all show up in this tab. It’s also the first place to check to see if your
Keyspan adapter is working properly.

The Properties tab allows you to test your Keyspan adapter and make
changes to its behavior. The following section explains the items in this
tab.
If you have multiple adapters connected to your computer, use the
Adapter pull down menu to select which USA-49WG you would like to
configure. If you only have one Keyspan USB 4-Port Serial Adapter, you
will not need to change the selection.
If you have more than one serial port on your Keyspan adapter, the Port
pull down menu allows you to select which serial port you want to modify
or test. You can also see the serial port’s COM port number and its COM
port status next to the Port pull down menu.
The Test This Serial Port button tests the selected COM port in the Port
pull down menu. The test performed is the one selected in the Serial Test
Options box. The Test All Serial Ports on this Adapter button tests all of
the COM ports on the selected adapter in the Adapter pull down menu.
The Test Mode box allows you to specify the type of test that will be
performed when you press the Test This Serial Port button.

There are 2 types of tests:
• TX Only: Use this test to test only the transmit (Tx) signals of the
Keyspan adapter.
• Ext. LoopBack: Use this test for sending and receiving data. This test
sends data out the selected serial port and waits to receive it via a
special Loopback connector. You can find more information about this
special Loopback connector in the Serial Ports Pinout section in this
manual.
The Test Type box allows you to specify how many times the selected test
will be repeated when you press the test button. Use the Quick option
to perform the test once. To perform a subsequent test, press the Test
This Serial Port button. Use the Continuous option to repeat the test
continuously. To stop the test, press the Stop Test button (the Test This
Serial Port button becomes the Stop Test button during a test).
The Test Speed pull down menu allows you to specify the speed (baud
rate) at which the port will be tested when you press the Test This Serial
Port button.
The Test Status box reports the test status or results of the selected COM
port.

The Receive FIFO Buffer Size pull down menu allows you to configure
the number of characters that are stored in the card’s “First In First Out”
input buffer (“FIFO”) before they are made available to the computer.
The default value of this parameter is “16”. The Receive FIFO Buffer Size
improves the reliability of data transfer at high speeds. You can turn this
option OFF for performance reasons. This is not necessary in most cases.
The Update Configuration button updates the Keyspan adapter with the
changes you have made in the Properties tab. Please note that these
changes will take effect when you click the Update Configuration button.
