CONNECTING THE USB PORT REPLICATOR

The USB Mobile Port Replicator provides one RS232 serial port, one

parallel port, two PS/2 ports, and two USB ports. This port replicator

provides easy connectivity for serial, PS/2, and other USB devices.

To get started, plug one end of the power adapter into the port replicator

and the other end into the wall outlet. Do not connect any devices at this

time. Once the port replicator is connected and the software installation is

complete, you can connect your devices and install any supporting software

drivers.

Plug the USB connector into the USB port of your computer, and plug the

other end into the USB port of the port replicator.

SOFTWARE INSTALLATION

Now you will install the drivers to support each port on the port replicator.

For the initial installation, you must complete each of the following three

steps to configure your USB Port Replicator ports and enable them for use.

The configuration will occur in the following sequence: the serial (RS232)

port first, then the parallel port, followed by the PS/2 ports.

If you are running Windows 98, you may need your Windows 98 CD to

complete the installation. During the installation, you may be prompted to

insert the CD. If you are running Windows 2000, you will only need the

included USB Port Replicator diskette.

Note: This procedure is divided into three steps and must be performed in

sequence, from Step 1 through Step 3. Do not skip any steps.

Step 1. Setting Up the Serial Port

When first connected, the New Hardware Detected dialog box will

appear, indicating that the Targus Serial Interface Controller is found. The

Add New Hardware Wizard window will then appear. ClickNext to

continue.

When prompted by the next screen, What would you like Windows to

do?, select Search for the best driver for your device, and clickNext.

When prompted to initiate a search for the best driver for your serial

device, insert the Targus USB Mobile Port Replicator disk. Then select

Floppy disk drives, and click Next to initiate the search.

When the software driver is located, and Windows is ready to install it,

click Next to continue with the installation.

When you see a message that Windows has finished installing the software

driver for the serial port, click Finish.

Step 2: Installing the Parallel Port Drivers

Next, theNew Hardware Detected dialog box will appear, indicating that

the Targus Parallel Interface Controller is found. The Add New Hardware

Wizard window will then appear. Click Next to continue.

Insert the Targus USB Mobile Port Replicator disk (if not already inserted)

and select Floppy disk drives. Click Next to initiate the search.

When the software driver is located, and Windows is ready to install it,

click Next to continue with the installation.

When Windows has finished installing the software for your parallel port,

click Finish.

Step 3: Installing the PS/2 Port Drivers

Each PS/2 port will install separately and the steps below will repeat.

Then, theNew Hardware Detected dialog box will appear, indicating that

the USB-PS/2 Converter is found. The Add New Hardware Wizard will

then install the native supporting drivers as a USB Human Interface

Device.

When prompted by the next screen, What would you like Windows to

do?, select Search for the best driver for your device, and clickNext.

When prompted to initiate a search, click Next.

When the software driver is located, and Windows is ready to install it,

click Next to continue with the installation.

Click Finishwhen Windows has finished installing the software for your

new device. Step 3 will repeat and install the second USB-PS/2 port driver.

Note: Before connecting a printer to the parallel port of the USB

Mobile Port Replicator, the printer driver must be installed. Otherwise,

the printer might print unknown formats or characters.

Congratulations! You have installed the Targus USB Mobile Port

Replicator. The new ports available to you are: one serial, one parallel, two

USB, and two PS/2. They are numbered sequentially following the existing

ports in your computer.

CONNECTING DEVICES TO THE PORT REPLICATOR

When connecting a new device to any port on the port replicator, the

corresponding software drivers must be installed. Consider the following

guidelines when preparing to connect new devices:

If your operating system is Windows 98, you will be prompted

by a series of screens beginning with Add New Hardware

Wizard. You may need your Windows 98 CD to complete the

installation.

If your operating system is Windows 2000, the operating

system drivers will install automatically.

With either operating system, you must run the Setup or

Install that was included with your device.

To load any device-specific software, assign the device to a

port as follows:

parallel printer PB1284-1 (USB port)

serial mouse or modem serial USB (COMx) where x is the

number of the COM port

PS/2 mouse or keyboard no port name required; the device

will be converted to emulate a USB

mouse or keyboard.

Installing a Serial Mouse

After connecting a standard serial mouse to the serial port on the port

replicator, press the Reset button until the Link LED flashes (about 5

seconds). Pressing the Reset button resets the serial port. Do this each time

you restart your notebook computer and whenever connecting a serial

device. Click Next to continue.

Installing a Serial Modem

Follow your modem installation instructions to add this device to your port

replicator. When prompted to select the port, choose the Serial USB

(COMx), where x is the COM port number assigned by your operating

system.

Installing a Parallel Printer - First-Time Installation

Follow the installation instructions that come with your printer. When

prompted to select a port, choose PB1284-1 (USB port). If this port does

not appear in the list, choose the LPT1 port, complete the manufacturer’s

setup for your printer, and follow the instructions below for Printer

Reconfiguration.

Printer Reconfiguration

Follow these instructions only if you are reconfiguring your printer from

the LPT1 port to the USB Port Replicator’s parallel port. Unplug the

printer cable from your notebook, and plug it into the port replicator

parallel port. Select Start, Settings, Printers. Right-click the printer

device you are reassigning, and select Properties. In the Printer

Properties window, select Details or Connection for the Printer.

(Section titles vary, so check your printer’s user manual for specific

instructions.) Change the setting to PB1284-1(USB port) to redirect

printing to the port replicator.

Installing a PS/2 Mouse or Keyboard

Simply plug the PS/2 mouse or keyboard into a PS/2 port on the port

replicator. Once the device is connected, it will be detected automatically

as a USB mouse or keyboard.

Installing additional USB Devices

To install any USB device, simply plug it into a USB port on the port

replicator. Follow the installation instructions provided with your USB

device.

SPECIAL NOTES

Global suspend the notebook computer

When your notebook computer is in suspend mode, the USB Mobile Port

Replicator will also enter suspend mode to avoid power consumption.

When your notebook computer wakes up, the port replicator will wake up

automatically.

Using the Reset button

The Reset button is used in conjunction with the serial port on the port

replicator. Whenever changing the serial devices connected to the serial

port, press and hold the Reset button until the Hub Link LED light blinks

so that the new device will be detected. Everytime your notebook computer

is powered on, press and hold the Reset button until the Hub Link LED

light blinks (about 5 seconds).

PRODUCT LIMITATIONS

Your port replicator is splitting a single connection among a variety of

devices and connections. Because of this, some devices that need a large

amount of bandwidth will consume all of the available resources and can

cause performance issues with the other devices attached.

We recommend the following guidelines:

Do not run multiple high speed devices at the same time, such

as a digital camera and scanner.

If speed degradation does occur, close one or more USB

applications to improve device performance.

There may be some temporary halting of some devices when a

high data transfer is occurring. For example, the USB or PS/2

mouse may respond slowly while a graphic print job is

printing.

The printer port is only compatible with printers and will only support

enhanced bi-directional printer features, such as your paper status.

An older mouse may not work with the port replicator because the software

driver cannot find the serial port without a direct connection to the

computer.

A PS/2 mouse attached to the port replicator is configured by the operating

system as a USB HID mouse. If the software driver continues to look for

the mouse on the PS/2 port, enhanced features may not be available and

your mouse will function as a standard, two-button mouse.

TROUBLESHOOTING

Perform these self-tests before calling technical support.

Device not recognized

Step 1 If a device attached to the port replicator is not recognized,

press and hold the Reset button until the lights flash. Verify

that the device is now recognized. If not, proceed to step 2.

Step 2 Detach all cables from the port replicator. Plug in the AC

Adapter. Connect the power cable to the power input jack.

Plug in each device, one at a time. Verify that each device is

recognized before plugging in the next one.

Step 3 If a device is not recognized, plug it into a different port on

the port replicator. If the device is still not recognized, try

plugging it into the USB port on your notebook computer.

Verifying devices are installed correctly

Step 1 Move the cursor to My computer and click the right mouse

button. Click Properties to display the System Properties

window. Next, click Device Manager and select ports COM

and LPT. The new path, Serial on USB [COM 2], appears

in the window.

Figure 1. Serial on USB [COM2]

Step 2 Within that same window, you will have a PA070 Parallel

Interface device. Look under Universal Serial Bus

controllers to see the other devices now installed for the port

replicator.

Figure 2. Serial Interface Controller

Modem connection

Step 1 When attaching a modem to the serial (RS232) port, verify

that the port assigned to your modem is Serial USB

(COMx), where x is the number of the COM port.

Step 2 If Windows does not Autodetect your modem on Serial USB

(COMx), rerun the Hardware Wizard. Choose Select from a

list instead of Autodetect, then select Serial USB (COMx)

as the COM port.

Printer

Step 1 The parallel port is designed to support parallel printers.

Data storage devices must be connected directly to the

parallel port on your notebook computer.

Step 2 If your printer is not recognized, click on Start, select

Settings, then select Printers. Highlight your printer, right-

click the mouse button, and select Properties. If the

assigned port is LPT1, change it to PB1284-1 (USB port).

Step 3 For a first-time printer installation, select the port PB1284-1

(USB port). If this port does not appear in the list, choose

LPT1 and proceed with your installation. Once completed,

follow step 2 above to set your printer port to PB1284-1

(USB port).

Mouse

Step 1 If your mouse is attached to the serial port, the enhanced

features (e.g. screen scrolling) may not be available. The

mouse will function as a standard, two-button serial mouse.
