Using the PowerBook Duo Dock
The PowerBook Duo Dock and Duo Dock Plus are the most versatile
expansion options for the PowerBook Duo. A Duo Dock itself is not a
computer—you need a PowerBook Duo to use it. But the dock and the
PowerBook together provide the video, storage, and input/output capabilities
available on most desktop Macintosh computers.
This guide explains how to set up a Duo Dock or Duo Dock Plus and connect
other components to it to create a PowerBook Duo System. Although the
illustrations in this guide show the Duo Dock Plus, all explanations and
instructions are correct for the Duo Dock, Duo Dock Plus, and Duo Docks
that have been upgraded to a Duo Dock Plus (except where specifically
noted). In this guide the term Duo Dock is used to refer to the three
configurations of Duo Dock, Duo Dock Plus, and an upgraded Duo Dock. For
information about using the Macintosh system software or the PowerBook
Duo, consult the documentation that came with your PowerBook.

Chapter 1
Setting up the Duo Dock
If you need to install a NuBus card inside the dock, do it before following the
steps below. See Chapter 3 in this guide for instructions.
1
Place the dock on a hard, flat surface.
While you set up, you’ll need access to the connectors on the back panel.
IMPORTANT Don’t attempt to use the dock on its side, or in any position other
than those pictured. Don’t block the ventilation slots on the sides or bottom of
the dock.
2
Plug one end of the dock’s power cord into the power receptacle (≤) on the back of the
dock, and the other end into an electrical outlet or power strip.
3
Put your monitor on top of the dock, and connect the monitor and power cables.
The Duo Dock can hold a monitor weighing up to 55 lb. The Duo Dock Plus
(or Duo Dock with the top cover upgrade) can hold a monitor weighing up
to 85 lb.
If you installed a monitor card in the dock, connect the monitor cable to the
card. Otherwise, connect the monitor cable to the dock’s monitor port
(marked with the icon ™). If you are connecting a VGA monitor, you need a
15-pin to 9-pin adapter.

Chapter 1
5
Now connect any other equipment you have, such as an external hard disk drive
or printer.
Follow the instructions that came with the equipment.
If you are connecting a SCSI device, you’ll need an HDI-30 SCSI System
Cable to attach it to the dock.
If you have a hard disk installed in your Duo Dock, you can chain up to five
additional SCSI devices to your PowerBook Duo System. If you do not have a
hard disk installed in your Duo Dock, you can chain up to six devices.
6
If you will be using network services, connect your LocalTalk (or other network) cable.
Follow the instructions that came with the cable, or check with your network
administrator. If you will be connecting your Duo Dock Plus (or upgraded
Duo Dock) to an Ethernet network, you need to connect the dock to the
Ethernet network and check that your PowerBook Duo has the correct
networking software. See Chapter 2 of this guide for details.
Once you have connected all your equipment, the Duo Dock is ready to use.

Working with the PowerBook Duo System
This section summarizes
m how your PowerBook Duo behaves when it is docked, or when it is moved
from one Duo Dock to another
m how to take advantage of the Duo Dock’s features
Your preferences
The PowerBook Duo uses your preferences—including desktop pattern,
window views, and so forth—when you dock it. This means that your
PowerBook will be customized the way you like it no matter where you work.
The PowerBook Duo can also remember certain selections that apply only
when you are docked (such as an Ethernet network setting). Each time you
dock, these settings take effect again without any action on your part.
Battery recharging
A docked PowerBook Duo draws power from the Duo Dock, not from its
own battery. The battery recharges while the PowerBook is in the dock.
You can remove the battery before docking if you want to recharge it in a
recharger. You can also remove the battery from the PowerBook while it is
docked if you want to recharge a second battery inside the PowerBook.
Power conservation
A docked PowerBook Duo does not sleep. You cannot put the PowerBook to
sleep as long as it remains docked.
The microprocessor in a docked PowerBook Duo does not
cycle on and off, because there is no drain of power from the battery.
10
Chapter 1
Hard disks
The PowerBook Duo starts up from its internal hard disk automatically. If
you have a hard disk installed in or connected to your Duo Dock, that disk’s
icon also appears when you start up.
You may prefer to start up from the Duo Dock’s hard disk when the
PowerBook Duo is docked. If so, use system software version 7.1 or later to
install a System Folder on that disk, and select it in the Startup Disk control
panel. See the instructions on installing system software in the
documentation that came with your PowerBook.
If you start up from the Duo Dock’s hard disk, the preferences selected on
that disk override those selected on your PowerBook Duo. When you use the
PowerBook away from the dock, the PowerBook uses the preferences
associated with its own hard disk.
Startup disk surprise? If you select the hard disk in the Duo Dock as your
startup disk, your PowerBook Duo will also start up from the internal hard
disk of any other Duo Dock you use. (This is because all Duo Dock internal
hard disks have the SCSI ID number 1.)
SCSI devices
If you have a hard disk installed in your Duo Dock, you can chain up to five
additional SCSI devices to your PowerBook Duo System. If you do not have a
hard disk installed in your Duo Dock, you can chain up to six devices.
Using the PowerBook Duo Dock
11
Virtual memory
The PowerBook Duo can borrow space on a hard disk to increase the
memory available for using programs. The disk space is called virtual
memory.
You can set aside virtual memory space on the hard disk belonging to either
the PowerBook Duo or the Duo Dock.
If you set aside virtual memory space on the dock’s hard disk, virtual memory
will not be on when you use the PowerBook outside the dock. The next time
you dock, virtual memory is turned back on automatically.
If you set aside virtual memory space on the PowerBook’s hard disk, virtual
memory is always available.
Networking
In addition to using your PowerBook’s built-in LocalTalk port to access a
LocalTalk network, you can also access another network type—such as
Ethernet or Token Ring—if you have a Duo Dock Plus, which has a built-in
EtherTalk port, or you have installed the appropriate NuBus card in your
dock. The first time you use the other network, you must open the Network
control panel and select that network type.
Once you have made a selection, the PowerBook remembers it whenever the
PowerBook Duo is docked. Whenever the PowerBook is not docked,
LocalTalk is the network type.
For more information about setting up and using your dock with an Ethernet
network, see Chapter 2 of this guide.
Modem
If you want to use an external modem with your PowerBook Duo System,
connect the modem cable to the Duo Dock port marked with this icon: W
If your PowerBook has an internal modem, select the Internal Modem in the
PowerBook control panel before opening your telecommunications program.
12
Chapter 1
If you have system problems
If your docked PowerBook crashes (the screen goes blank or fills with
gibberish) or freezes (the pointer doesn’t move and input devices don’t work),
press the power button on the back of the dock once. Pressing once turns the
PowerBook off. Use the Power On key on your external keyboard to turn the
PowerBook on again.
Pressing the power button erases any information you did not save, but it
allows you to restart the system and continue working.
See the troubleshooting information in the documentation that came with
your PowerBook for more information about handling system problems.
Using security features
The Duo Dock has a key-operated mechanical lock to prevent theft of a
docked PowerBook Duo. You can also lock PowerBooks out of the dock—for
example, to protect information on the dock’s hard disk or to limit access to
a network.
You can lock the dock when the PowerBook is inside or outside the dock.
You can lock the PowerBook inside the dock when the PowerBook is on
or off.
To lock or unlock the dock, turn the key as shown in the illustration.
Locked
Unlocked
Using the PowerBook Duo Dock
13
Each Duo Dock comes with two keys. If you lose both of them, you can:
m Contact the lock vendor for a replacement set of keys. Write to Fort Lock
Corporation, 3000 N. River Road, River Grove, IL 60171, USA, or call
708-456-1100 (in Illinois). Be prepared to supply the code number printed
on the tag that came with the keys.
m Have a locksmith make a replacement set of keys.
m Have your Apple-authorized service provider replace the entire lock
assembly. The new assembly comes with two new keys.
All these procedures may be expensive and time-consuming. It’s a good idea
to take precautions not to lose the keys.
The Duo Dock also has a security slot in the back panel to which you can
connect an optional locking cable, to prevent theft of the dock. See an Appleauthorized dealer for more information.
14
Chapter 1
Ejecting the PowerBook Duo from the Duo Dock
1
Shut down the PowerBook Duo by choosing Shut Down from the Special menu.
If a system problem prevents you from using the menu, you can shut down by
pressing the power button on the back of the dock (but you’ll lose work you
haven’t saved).
2
Unlock the dock (if it is locked).
Turn the key to the vertical (unlocked) position.
3
Press the eject button.
Eject button
The dock ejects the PowerBook far enough so you can pull it out.
A useful shortcut
You can shut down the PowerBook Duo and eject it by simply pressing the
eject button (if the dock is not locked). When you do this, the system will
m remind you to save your work, if you haven’t done so
m close any open programs
m terminate your network or modem connections
m shut down the system
m eject the PowerBook Duo from the dock
If you press the eject button while the dock is locked, a message reminds you
to unlock it.
Using the PowerBook Duo Dock
15
Trouble?
m The dock doesn’t eject the PowerBook.
The dock may be locked. Unlock it by turning the key to the vertical
(unlocked) position, and press the eject button again.
There may be no power to the dock. To eject the PowerBook manually,
insert the dock’s key, a small screwdriver, or a similar object into the square
hole on the side of the dock and press firmly. The dock is released, and
you can gently pull the PowerBook from the slot.
Manual eject hole
When the dock is locked, you can’t use the square hole.
WARNING Manually ejecting the PowerBook Duo when it is running can
damage your system. Check that your PowerBook is turned off before
manually ejecting it.

Using Your Duo Dock
on an EtherTalk Network
The Duo Dock Plus comes with a built-in Apple EtherTalk port. You can also
purchase and install an EtherTalk network card in your Duo Dock. If you
have a Duo Dock Plus, or have installed an EtherTalk network card, you can
use the dock to connect to Ethernet networks to access a variety of
networking capabilities. Ethernet is a widely used communication standard
that supports very high transmission speeds for information.
With Ethernet, you can
m gain access to information on other computers
m allow access to information on your own PowerBook
m print documents on network printers
m link your programs to programs on other computers and share the features
between those programs
m update files over the network automatically
m designate specific information on your PowerBook as “shared files” that
other users can access over the network
17
You can connect the Duo Dock Plus to one or more computers with an Apple
Ethernet connector and any standard Ethernet cable.
Attach an Ethernet transceiver to
the Ethernet port on the Duo Dock.
Ethernet transceivers
To set up your Duo Dock Plus (or upgraded Duo Dock) to use Ethernet,
you must
m connect the dock to the Ethernet network
m check that you have the Ethernet software installed on your PowerBook
Duo, and install the software, if you do not. See “Checking Your
Networking Software” in the section “Connecting Your Duo Dock to
Ethernet” later in this chapter.
m open the Network control panel and select Ethernet as the network you
want to use
After setting up your dock, you may need to contact your network
administrator for additional information.
18
Chapter 2
Connecting your Duo Dock to Ethernet
Before you can use your dock on a network, you must connect it to the
Ethernet network by connecting an Ethernet adapter and cable to the
Ethernet port on the dock. After connecting the dock, you must put the
PowerBook Duo in the dock and make sure your PowerBook can
communicate with the network.
With the appropriate Apple Ethernet adapter (or other compatible adapter),
you can connect your Duo Dock to an existing Ethernet network using thin
coax, 10BASE-T twisted pair, thick coax, or other standard cables. (See an
Apple-authorized dealer for more information on Apple Ethernet adapters for
your Duo Dock.)

Using Your Duo Dock on an EtherTalk Network
19
Note: The Ethernet illustrations in this chapter show the thin coaxial
connector type. The connector you use may be different.
IMPORTANT The built-in Ethernet capabilities of your Duo Dock allow you to
connect to any standard Ethernet network. The built-in Ethernet supports
EtherTalk Phase 2 (AppleTalk Phase 2 protocols for Ethernet networks).
There are also Apple and non-Apple products that you can use to
communicate over Ethernet using other protocols, such as MacTCP.
The built-in Ethernet does not support EtherTalk Phase 1 (AppleTalk Phase 1
protocols for Ethernet networks).
There are two ways to connect the Duo Dock to an Ethernet network:
m connect the dock between other devices in a network
m connect the dock to the end of an existing network
An EtherTalk network consists of a group of devices, called nodes, linked
together by Ethernet cables. Individual nodes on a network can include a
variety of devices, such as computers, printers, or other equipment.
Connecting the Duo Dock between two devices on an
Ethernet network
When you connect the Duo Dock between two devices on a network, you’ll
need to briefly interrupt communication between network users on both sides
of the connection, unless they are linked through some other network route.
Be sure to notify users before adding the Duo Dock to the network.
1
Plug the short cable extending from an Apple Ethernet adapter into the Ethernet port on
the dock.
The Ethernet port is at the center of the connector panel on the back of the
Duo Dock.
20
Chapter 2
2
Disconnect one Ethernet cable from the adapter of the network device immediately to the
left or right side of the dock.
3
Plug one end of an Ethernet cable into the socket you have just freed and the other end
into one of the sockets of the dock’s Ethernet adapter.
4
Plug the Ethernet cable you disconnected in step 2 into the remaining socket of the
dock’s Ethernet connector box.
Connecting the Duo Dock to the end of an Ethernet network
Connecting the Duo Dock to the end of a network will not interrupt
communication among network users. You do not need to shut down any
computers or notify users before adding the dock to the network.
1
Plug the short cable extending from an Apple Ethernet adapter into the Ethernet port on
the dock.
The Ethernet port is at the center of the connector panel on the back of
the dock.
2
Use an Ethernet cable to connect the adapter to the network as shown.
Using Your Duo Dock on an EtherTalk Network
21
Connecting the Duo Dock directly to your printer
The Ethernet port is used most often to connect the dock to a network.
However, if you are using the dock and PowerBook Duo as a stand-alone
computer, you can use this port to create a direct, high-speed connection to a
printer that also has an Ethernet port (this creates a small Ethernet network
consisting of the workstation and printer).
1
Plug the short cable extending from an Apple Ethernet adapter into the Ethernet port on
the dock.
The Ethernet port is at the center of the connector panel on the back of
the dock.
2
Plug an Ethernet connector into the Ethernet port on your printer.
3
Connect the two Ethernet adapters with an Ethernet cable, as shown.
Checking your networking software
If you have the EtherTalk and networking software already installed on your
PowerBook Duo, you can select a network connection and begin using the
network. If you don’t have EtherTalk or networking software installed on your
PowerBook, you can install it using the Installer program on the system
software disks that came with your PowerBook Duo (or with a system
software upgrade kit that you purchased).

Selecting a network connection
Once you have installed EtherTalk networking software on your PowerBook,
you must select the appropriate connection type in the Network control panel
before you can use it.
You can switch to a different network connection type at any time. For
example, if you have access to both a LocalTalk and an Ethernet network
(using EtherTalk), you can switch between the two connection types.

Installing a NuBus Card
Installing a NuBus card in the Duo Dock is a technically challenging
procedure. We recommend that you attempt it only if you are comfortable
working with electronic equipment. You should read all of the following
instructions before you begin. If the procedure sounds like something you
don’t want to do yourself, any Apple-authorized service provider can install a
NuBus card for you.
WARNING To avoid damaging your computer and expansion card, do not
attempt to install any expansion card without first checking the
documentation for that card. If the documentation specifies that an
Apple-certified technician must install the card (usually because the
installation requires special training or tools), consult the service and
support information that came with your computer for instructions on
how to contact an Apple-authorized service provider or Apple for
assistance. If you attempt to install the card yourself, any damage you
may cause to the computer or card will not be covered by the limited
warranty on your computer. If the card is not an Apple-labeled product,
check with an Apple-authorized dealer or service provider to see if you
can install it yourself.
27
Getting ready
You need the Duo Dock, a NuBus card, and either a flat-slot or Phillips
screwdriver (depending on the type of screws you see in step 5 under
“Installing the Card”).
If your system is already set up: Turn off, disconnect, and remove all
equipment attached to the dock, but do not unplug the power cord that
connects the dock to an electrical outlet or power strip.
Installing the card
1
Unlatch the top cover of the dock by pinching the grooved surface just inside the
front opening.
2
When the latches release, tilt the cover upward slightly (to about a 30° angle) and then lift
the angled cover straight up to remove it.

Disconnect the power supply cable by pinching its release clip and pulling straight up.
If there is a hard disk drive in your Duo Dock, you may need to move its
ribbon cable aside to reach the clip on the power supply cable.
Pinch clip and then pull up.

5
Loosen the two screws connecting the central part of the dock to the base. (In the rest of
these instructions, the central part of the dock is called the subassembly.)
Check the screws to determine whether they are slot or Phillips screws and
then select the appropriate screwdriver. Turn the screws counterclockwise.
The screws don’t come out all the way, so you can’t remove them completely.

Pull the subassembly toward you until you feel it come to a stop.
It will move only a short distance. You’ll be able to feel a small gap under the
front ledge of the dock.
If the subassembly doesn’t seem to move, or if you can’t feel a gap under the
front ledge, the screws may not be loose enough. Turn them a few more times
and try again.
The subassembly is heavy, so before you continue with step 7, make sure that
you have enough room to put it down nearby after you lift it off the base.

Push out either cover plate.

Push out the plastic cover plate behind one of the NuBus slots and set the plate aside.
Use your thumb to push out the cover plate.
About NuBus slots and cards: The two NuBus slots in the Duo Dock are
stacked vertically. The slots are identical, so you can install your card in either
one. If you install your card in the upper slot (which is the lower slot when
the dock is right side up), you’ll have to remove it and reinstall it if you want
to add a second card later.
NuBus cards come in different shapes and sizes. All properly designed cards
will fit into the Duo Dock. You may find it easier to install a large card in the
upper slot rather than the lower one.

Remove the plastic NuBus card guide next to the floppy disk drive by pulling it
straight out.

The next four steps describe how to insert the card.
IMPORTANT Handle a NuBus card by its edges only, and be careful not to
touch the pins inside the connector.
11
Lower the card into the slot.
NuBus cards have all or most of their chips on one side. Hold the card so its
chips are facing up, and the connectors on the card and the slot are aligned.
You may need to tilt the card as you lower it into the slot.

Replace the dock cover.
Align the cover over the base so that the corners align with the back edge of
the base. Press down firmly on the rear corners and then press down on the
front corners until the latches click.
WARNING Never turn on your computer unless all of its internal and
external parts are in place. Operating the computer when it is open or
missing parts can be dangerous, and can damage your computer.
See the information that came with your NuBus card for information about its
accompanying software (if any) and use.
