USB port of your computer.
5 Turn on your computer.
The following will configure automatically:
• Ethernet 10/100 (Model PA095 only)
• Serial Interface Controller
• USB Device (twice)
• Parallel Interface Controller
• PS/2 Adapter (twice)
This configuration process takes a few minutes. The
operating system does not prompt when configuration is

before opening another application or connecting devices
to the port replicator.
NOTE: some hardware devices may prompt you for the
location of device drivers.
To install the drivers:
1 Select “Install the software automatically
(Recommended)” and click Next.
The Found New Hardware Wizard program begins
installing the hardware drivers.

5
The Completing the Found New Hardware Wizard
screen appears.
2ClickFinish and repeat as needed for each device.
3 Restart your computer.
When your computer restarts, the port replicator/dock
should be completely configured.
LED Status Indicator Lights
Once all device drivers are installed, the LED status
indicator lights glow and you can connect devices to the
port replicator. The LED lights display as follows:
• Hub Link light blinks green.
• Serial light glows green.
• Each PS/2 light flashes green when a device is first
connected or there is activity on the port.
• USB lights glow green when a USB device is attached.
(Model PA095 only)
• Tx/Rx light flashes green when data is transmitted to or
from the network.
• 100M light glows green when connected to a 100 Mbps
network.
NOTES: The Ethernet port is compatible with 100 Mbps
networks. however, the actual throughput is 10 Mbps
maximum when connected to a USB v1.1 port due to the
bandwidth limitation. The throughput may decrease as
additional devices are attached to the port replicator
regardless of whether the port replicator is attached
to a USB 1.1 or 2.0 port.

6
The port replicator supports hot swapping of the
network cable.
Connecting Devices to the Port
Replicator
When connecting new devices to the port replicator, you
may need to install additional software drivers. Consider the
following guidelines:
• The device drivers install automatically.
• When connecting a new device to the port replicator, you
must run the Setup or Install program for that device.
• When connecting a device to the port replicator, do not
force the cable connector into the port on the port
replicator, to avoid possible damage. If the cable
connector does not attach smoothly, turn the connector
over and try attaching it again.

USB (COMx), where xis the COM port number
assigned by your operating system.
Connecting a Handheld Computer
To connect a handheld computer:
1 Attach the cable connector to the serial port on the port
replicator.
2 Verify that the COM port setting, in either your
HotSync®or ActiveSync®software, matches the setting
on the port replicator. To verify the COM port setting on
the port replicator, refer to “Verifying Devices are
Installed” on page 11. To verify the COM port setting on
your handheld computer, refer to the documentation that
came with it.

port replicator and follow the additional instructions
provided with the device.
Special Notes
Using a Device with the Port Replicator
When you connect a device to the USB Mobile Port
Replicator, you should be able to use it as you normally
would.
NOTE: devices that support custom programmability
or special features may not function properly. For
more information on using a device, refer to the
instructions provided with the device.
Global Suspend Mode
When your computer is in suspend mode, the port
replicator also enters suspend mode to avoid power
consumption. When your computer wakes up, the port
replicator wakes up automatically.

Product Limitations
General
The port replicator splits a single connection among a
variety of devices and connections. Some devices, which
use large amounts of bandwidth, such as printers and
digital cameras, can consume all available resources and
may interfere with the performance of other devices.
You may experience some temporary halting of some
devices when a high data transfer is occurring. For example,
your mouse may respond slowly while a graphic print job is
printing or while you are experiencing heavy network traffic.
We recommend the following guidelines:
• Do not transfer data to or from multiple high-speed
devices at the same time, such as a digital camera and
scanner.
• If speed degradation does occur, close other programs
that use a USB device to improve device performance.
Parallel Port
The parallel port is only compatible with printers and only
supports enhanced bi-directional printer features, such as
returning printer status. For best results, you should
connect high bandwidth external devices, which have a
parallel connection, such as a Zip®drive, directly to your
computer.
PS/2 Mouse and Keyboard
On the port replicator, a PS/2 mouse emulates a USB
mouse and a PS/2 keyboard emulates a USB keyboard.
This may result in a loss of enhanced features, such as
screen scrolling or programmable hot key features.

11
However, the mouse will continue to work as a standard,
two-button mouse and the keyboard as a standard
keyboard.
Troubleshooting
Device Not Working
• Make sure that the device is fully inserted into the correct
port on the port replicator.
• Plug the device into a different port on the port replicator.
If it still doesn’t work, test the device by connecting it
directly to your computer.
• Verify that you ran the Setup or Install program for the
device.
• Make sure that the device appears in Device Manager.
For more information refer to “Verifying Devices are
Installed” on page 11.
• Disconnect all devices from the port replicator and
reconnect them, one at a time. Check that each device
works before plugging in the next one.
Printer Not Found
If your parallel printer is not working, refer to “Checking and
Redirecting the Printer Port Settings” on page 8 for
instructions on how to verify and change the port settings.
Verifying Devices are Installed
You can view the devices installed on the port replicator
from the Device Manager window in System Properties.
Right-click My Computer, Properties, then click the
Hardware tab, and then the Device Manager button.

12
Sample Device Manager tab (Windows®XP operating system)
From the Device Manager window, expand the following:
• Human Interface Devices — displays PS/2 Keyboard and
Mouse Adapter when a PS/2 device is plugged in.
• Network adapters — displays USB Ethernet 10/100
(Model PA095 only)
• Ports (COM & LPT) — displays the Serial on USB [COM
2] port
• Universal Serial Bus controllers — displays the other
devices installed for the port replicator. (USB hub,
composite device, and printing support)
Verifying a Serial Modem Connection
When attaching a modem to the serial (RS232) port, verify
that the port assigned to your modem is Serial USB
(COMx), where xis the number of the COM port.

13
If the operating system does not detect automatically that
your modem is assigned to Serial USB (COMx), rerun the
Hardware Wizard and choose Select from a list instead of
Autodetect. Then, select Serial USB (COMx) as the COM
port.
Error Message on Your Handheld Computer
If the error message “Connection Not Established” appears
on your handheld computer, check that the COM port
setting in either your HotSync or ActiveSync software,
matches the setting on the port replicator, see “Verifying
Devices are Installed” on page 11 to verify the COM port
setting on the port replicator.
You may also want to try reducing your baud rate setting in
Hot Sync or Active Sync.
Some older versions of the Palm®Desktop software are not
compatible with the USB to Serial conversion. Please
contact your handheld computer vendor for software
updates.
