Dirt and debris can get underneath the keyboard bezel. To clean, use
a coin (do not use a screwdriver) to pull the bezel up at the recess
located at the bottom of the keyboard and remove it. We recommend
that you use warm water, mild detergent, and a toothbrush to clean
the keyboard or simply brush it out. The Allegro remains sealed
during this process. (Do not direct a high pressure stream of water at
the keyboard to clean it. This action could break the seal, causing
water to get inside the Allegro.)
Reattach the bezel by carefully inserting the top ridge under the
function keys and lowering the bezel down flat onto the case. Press
down along the sides while aligning the keys through the holes.
❖ Note: After you reattach the bezel, check each key to make sure it is
completely free from the bezel. If any part of a key is caught underneath the
bezel, you may not be able to turn the Allegro on or you may hear a
continuous string of beeps.

Batteries
The power consumption of the Allegro CE is very efficient. The Auto
Suspend and Power Management features help to conserve power.
Maintaining the battery pack and backup supply is simple.
There are two types of batteries and a backup capacitor associated
with the Allegro:
❏ NiMH battery pack
❏ Battery holder for three alkaline cells (optional accessory)
❏ Super capacitor that serves as the RAM backup (maintains the
RAM while you change the battery pack)
▲▲
▲ Main Power Source
▲▲
The Allegro is powered by a rechargeable nickel metal hydride
(NiMH) battery pack. The battery compartment is accessed through a
door in the back of the case. The NiMH battery pack is shipped along
with the Allegro but is not installed at the factory. When you receive
the Allegro, you must install and then charge the battery pack. To do
this, complete the following steps:
1) Push up on the sliding latches on the sides of the Allegro to open
the battery compartment door .
2) Place the NiMH battery pack in the left side of the battery
compartment, push down, and slide it all the way to the right.
3) Push the battery door closed until each latch clicks into place.
Hardware Features Page 2-19
4) Slide the latches downward until they cannot slide any further to
securely latch the battery door closed.
Do not turn on the Allegro yet.
5) Plug the AC wall charger that came with the Allegro into the wall
socket.
The small green light on the wall charger turns on when it is
plugged in.
6) Remove the rubber protector from the Allegro’s external power
input jack.
7) Plug the power connector end of the wall charger into the Allegro.
8) Charge the battery pack at room temperature until the charge
indicator on the Allegro turns off. This can take 3 to 5 hours the
first time you charge the battery.
Page 2-20 Hardware Features
Setting Battery Charge
After installing the battery pack into the Allegro, the battery charge
percent must be set. This allows the Allegro to know the pack’s
charge status. When you insert the battery pack into the Allegro for
the first time, the charge status is unknown to the Allegro.
To set the charge status of the battery pack after you install the battery
pack for the first time, complete the following:
1) T urn on the Allegro by pushing the On/Off button.
As Windows CE loads, various scr eens appear that do not requir e
any action until it gets to the New Battery Detected screen.
2) T ap on the cir cle next to the Specify charge (%) option to set char ge
status.
3) Set the charge percent to 10 by taping on the small up or down
arrows to move the percent.
The capacity of the NiMH battery we have provided with the
Allegro is 3800 mAh, so this will not change.
4) T ap on OK to save the set char ge percent.
The New Battery Detected screen closes and the charge status is set.
Once the battery pack is fully charged, the gauging is automatically
set to 100%. The battery task bar icon indicator now accurately
reflects the battery charge.
Hardware Features Page 2-21
New Battery Detected Screen
There are other situations when you turn on your Allegro and the
New Battery Detected screen pops up, directing you to set the values for
battery charge percent and battery charge capacity. The following are
reasons for this:
- Restore function is used
- Set Factory Defaults function is used
- Power is removed from the Allegro because the battery is fully
discharged
- Removal and replacement of the battery pack
These values must be set correctly for the battery charge function to
work properly, as previously outlined in this section.
If you insert a battery pack and do not know what the status its is, we
recommend you follow the previous instructions and set the battery
charge at 10%.
If you do know what the status is, then set the correct percentage and
tap on OK.
Setting the Battery Capacity
The battery capacity is set to the default of 3800 milliamp-hours
(mAh) forthe newly installed battery pack. The capacity of the NiMH
battery we have provided with the Allegro is 3800 mAh.
If you purchase a battery pack from another vendor, note what the
capacity is. For optimum performance, it is best to use battery packs
with a 3000 to 4000 mAh capacity. The higher the capacity of the
battery pack, the longer it holds a charge. However, battery packs
with a capacity over 4000 mAh may not charge fully.
As a battery pack ages, it does not operate as long on a charge as it
did when it was new. The capacity could be reduced by as much as
50% at the end of its useful life. Over time, the capacity setting for an
individual battery pack may be adjusted downward to account for
age.
Page 2-22 Hardware Features
Battery Life
Depending on the application, the batteries can last from five to 30
hours between charges (NiMH) or replacement (alkaline cells) as
shown below:
Battery Pack Capacity Typical Operating Time
NiMH 3,800 mA hours 12 to 20 hours
Alkaline 1,600 mA hours 5 to 10 hours
The operating times stated above are based on a typical application
including: the data are being entered manually on the keyboard, no
external devices are powered by the Allegro, the backlight is used
10% of the time, and processing time is 20%. The actual operating
time could vary from as little as five hours to as much as 30 hours,
depending on the program and how the system is set up.
Recharging the NiMH Battery Pack
For applications where the Allegro is used for several hours each day,
the NiMH batteries can be charged daily. The Allegro’s built-in
intelligent charging circuit manages the charging of the batteries and
prevents them from being overcharged.
You should always be aware of the status of the main batteries before
you go out into the field to collect data. The batteries may need to be
recharged before you go. You need to take into account how much
battery life is left and the amount of time required to charge the pack.
Temperature Ranges for Charging the NiMH Battery Pack
The Allegro’s NiMH batteries are charged most efficiently at
temperatures ranging between 10° to 20° C (50° to 68° F) when the AC
power adapter is used.
The Allegro batteries must be charged when the battery temperature is
between 0° to 40° C (32° to 104° degrees F) due to the nature of NiMH
batteries.
Hardware Features Page 2-23
The chart below describes the Allegro battery charging behavior at
different temperatures.
Temp. Range Temp. Range
Degrees C Degrees F Charging Behavior
Recommended 10° to 20° 50° to 68° Most efficient; batteries charge
Charge Range within three hours.
Acceptable 0° to 30° 32° to 86° Batteries are charged within four
Charge Range hours.
Too Cold < 0° < 32° The batteries must reach 0° C (14°
Range F) before they begin to charge.
Too Hot > 30° > 86° Battery charge cycle is complete in
Range four to five hours. If the batteries
become too warm, they may only
reach a 90 to 95% charge capacity.
Try to charge the batteries within the recommended temperature
range. If you need to charge the batteries in temperatures exceeding
this range, you should purchase an extra battery and keep it charged
for the most efficient operation of the Allegro.
Power Connector
A dedicated standard external DC power input connector is located
on the top of the Allegro. The connector is 5.5 x 2.1 mm, 10 to 20 V DC.
The AC power adapter and optional vehicle power adapter are
inserted into this connector.
< Power Connector
Charging Accessories for NiMH Battery Packs
There are several charging options available for the Allegro. The most
common is the AC power adapter that is shipped with your Allegro.
The USB/Power Dock, vehicle power adapter, and external battery
charger are all optional ways of charging the Allegro and can be
purchased seperately.
❏ AC Power Adapter: Using the AC power adapter, the battery pack
is recharged without removing it from the Allegro.
Please note that you must use the adapter included with the
Allegro or one that is capable of supplying adequate current (12 V
at 1 Amp). Otherwise, the battery pack could be damaged.

2) Slide the battery onto the charger and leave until fully charged,
which can take up to five hours. Refer to the instructions that
came with the charger for more details. (Details on how to
remove the battery pack are located later in this chapter .)
Using Vehicle Power
It is important to have the Allegro in Vehicle Mode when it is left
connected to vehicle power for periods of an hour or more, either
directly or via the vehicle power adapter. Vehicle Mode prevents
excessive charging of the NiMH battery pack.
Using Vehicle Mode is necessary because every time the power is
cycled (the key to the vehicle is turned on) the Allegro begins a new
battery charge cycle. The Allegro circuitry detects when a battery
pack is fully charged, however, it takes approximately 20 minutes for
this to occur. Repeatedly attempting to charge a fully charged battery
pack causes premature degradation in battery performance. In
Vehicle Mode, charging is inhibited if the gauging circuitry indicates
that battery pack is above 90% charged.
To put the Allegro in Vehicle Mode, complete the following steps (the
default is for Vehicle Mode to be off):
1) T ap on the Start menu and select the Settings|Control Panel options,
double-tap on Power icon. The Power Properties screen appears.
2) T ap on the box next to the Select the In-V ehicle Charge Mode option
so a check mark appears. (Refer to Chapter 4, Windows CE, Control
Panel for details).
3) T ap on OK.
Your Allegro is now set up fur use in vehicle power mode.

Battery Gauging Explained
The Allegro's intelligent battery gauging circuit helps you efficiently
maintain the batteries for applications. The percentage of remaining
charge in the batteries is indicated through the battery status system
tray icons. The gauging works for both NiMH rechargeable batteries
and alkaline batteries, although the mechanism is different, as
outlined in this section.
❖ Note: Battery gauging is provided as a tool to help you manage the
batteries. It does not affect the performance of the Allegro or the batteries in
any way. If the gauging circuitry is not properly synchronized with a
NiMH battery, it may show erroneous readings. Please read this section on
battery gauging so you understand the proper setup, functionality, and
limitations of battery gauging.
How Battery Gauging Works for the NiMH Rechargeable Battery
The Allegro employs a circuit that watches how much charge is
added to or removed from the rechargeable battery.
To illustrate how this circuit works, imagine the battery as a tank of
water. The battery capacity is like the size of the tank in volume.
Watching the charge is like watching how much volume of water
flow into or out of the tank.
Gauging the battery is like gauging how full the tank is, without
being able to see into it. You must know the size of the tank and how
full it was to start with to determine the amount of water in the tank.
As water flows out of the tank, the percent full can be calculated by
subtracting how much water has flowed out of the tank from the
starting point and then dividing by the capacity of the tank. This is
exactly what the Allegro does, except it monitors milliamp-hours of
electric charge instead of the volume of water.
For the battery gauging to work correctly on the Allegro, the following
values must be known about the NiMH battery pack:
- Charge percent
- Capacity
Setting the battery charge percent and capacity are both discribed
earlier in this chapter in the Setting Battery Charge section.
Hardware Features Page 2-27
The battery gauging is an estimate. It works well in applications
where the Allegro is used heavily and charged every day. When it is
not used much and goes several days between charges, the gauging
may not be as accurate in reflecting the true charge of the battery
pack. The accumulated error can be as much as 5% per day.
To avoid errors, keep the Allegro attached to the AC charging adapter
or in the USB/Power Dock when you are not going to use it for a few
days. This practice prevents the battery pack from self-discharging.
The battery stays fully charged and the battery gauging reflects the
correct status of the battery pack.
How Battery Gauging Works When Using Alkaline Batteries
Alkaline batteries have a better slope to the voltage discharge curve
than NiMH batteries. Because of this, the voltage can be read directly
to gauge the battery charge percent.
The gauging may vary depending on the grade and brand of the
batteries being used. For best results, we recommend that you use the
new types of alkaline batteries such as the Duracell Ultra™ and
Energizer Titanium™.
Temperature and loading affect alkaline battery voltage and may
cause the gauging to behave differently in different environmental
conditions. When moving from a cold environment to a warm one, the
battery charge status bar indicators may actually move up instead of
down. This happens because in cold temperatures the alkaline
batteries actually have less capacity than in warm temperatures and
this is reflected in the voltage output.
Battery Status Icons
There is a battery indicator in the system tray that shows the amount
of power left on the battery. The indicator gives a percentage of the
charge left in the battery, as shown below:
❖ Note: The system tray indicators are meant to give only an approximate
indication of battery charge remaining, not an exact reading.
Page 2-28 Hardware Features
When the Battery Voltage Drops
As the battery charge drops to 10%, the voltage begins to drop off
rapidly. The Allegro detects this low battery condition. When the
battery indicator begins to flash on and off this lets you know it is
time to recharge or replace the batteries.
When the battery pack voltage drops sufficiently, the Allegro
automatically goes into suspend mode. Charge or replace the batteries
as soon as possible. The battery pack has enough charge left to retain
the system RAM for five minutes, at which point the Allegro
completely powers down to prevent damage to the batteries. If this
happens, the Allegro resets after you charge or replace the batteries.
Any data that were not saved to disk are lost.
Lost Data if Batteries are Removed
If the batteries are removed from the Allegro for longer than five
minutes, the Allegro resets to the Desktop instead of resuming to the
screen that was last displayed before the batteries were removed. All
data that was stored in RAM are lost.
Power Management Feature
To conserve power, the Allegro has an Auto Suspend feature. When
the Allegro is on, it turns itself off if there is no activity after a
specified period of time. This feature is on by default and is set at
three minutes when the Alegro is using battery power or always on
when the Allegro is connected to the an external power supply. The
Auto Suspend is controlled through the Start|Control Panel|Power
menu.
Changing NiMH Battery Pack
The battery compartment is accessed through a door in the back of the
case. Before you remove an existing battery pack from the Allegro,
complete the following:
1) Exit from all open programs.
2) T urn the Allegr o off.
3) Push up on the sliding latches on the sides of the Allegro to open
the battery compartment door .
4) Slide the battery pack towards the left side of the battery
compartment and pull it out.
Hardware Features Page 2-29
5) Place the new battery pack in the left side of the battery
compartment, push down, and slide it all the way to the right.
6) Push the battery door closed until each latch clicks into place.
7) Slide the latches downward until they cannot slide any further to
securely latch the battery door closed.
Alkaline Battery Holder: Inserting Batteries and Usage Information
The alkaline battery holder enables you to power the Allegro with
alkaline batteries. Follow the steps outlined below for proper usage.
1) T urn the Allegr o off before changing the batteries.
2) The Allegro battery compartment is accessed through a door in the
back of the case. T o open the compartment door , push up on the
release latches on the sides of the case. The door pops open.
Remove the alkaline holder or NiMH pack by sliding it to the left
and pulling it out.
3) Open the door to the alkaline battery holder by pressing in on both
tabs with your index finger and thumb as shown.
4) Insert three fresh AA alkaline batteries, taking care to orient them
correctly (only use alkaline batteries). Always replace all three
batteries at once.
❖ Note: For best results, we recommend that you use the new types of
alkaline batteries such as the Duracell Ultra™ and Energizer Titanium™.
Page 2-30 Hardware Features
5) Slide the door to the alkaline holder back into place, making sure it
snaps securely shut.
6) Place the alkaline battery holder in the left side of the Allegro
battery compartment. Put gentle pressure on the holder while
sliding it all the way to the right.
7) Press down on the Allegro battery compartment door to close it.
The latches should automatically lock the door into place and seal
the compartment. Make sure that the slide latches are completely
closed.
8) Occasionally check the battery task tray indicators on the Allegro
display while you are using the Allegro. When the battery power
gets low , replace the alkaline batteries or insert a NiMH pack.
Important Information Regarding the Use of Alkaline Batteries
The Allegro is designed to be used with the rechargeable NiMH
battery pack that came with the unit. The alkaline battery option
should be considered as a backup to the NiMH battery pack, not as
the main source of power for an extended period of time.
Alkaline batteries have a lower capacity and a higher resistance than
NiMH batteries. The battery life and performance of the Allegro is
reduced when alkaline batteries are used. The alkaline batteries have
the following limitations:
❏ The display heater cannot be ensabled.
❏ As the batteries reach low power, the Allegr o automatically
disables the backlight to reduce power consumption.
❏ The battery life ranges between 5 and 10 hours (this is highly
dependent on the temperature).
Storing the Allegro CE During Inactive Periods
To protect the Allegro and your files during long or short-term storage
periods, please take the following precautions:
❏ Close all application programs.
❏ Run the Save System utility.
The data and programs are secure as long as they have been saved to
the non-volatile solid state storage, even if the batteries become
discharged. The Allegro does not depend on the battery to store the
data for extended periods.
Hardware Features Page 2-31
Storing the Allegro CE for Less Than Two Months
If you store the Allegro for less than two months, we recommend that
you leave the NiMH battery pack in the Allegro and attach the AC
power adapter to keep the batteries charged or leave the Allegro in the
USB/Power Dock.
Once the battery pack is fully charged, the Allegro switches to trickle
charge mode. You can leave the Allegro in trickle charge mode
continuously without damaging the batteries. The battery pack will
be fully charged when you are ready to use the Allegro.
❖ Note: Do not leave the Allegro plugged into a wall outlet where the
power to that outlet cycles on and off frequently. The battery can become
damaged from overcharging.
Storing the Allegro CE for More Than Two Months If you store the Allegro for more than two months, perform a Save System to save all data on the Allegro’s internal data storage, remove
the battery pack from the Allegro, and place the Allegro on a shelf.
When you are ready to use the Allegro, insert a battery pack and fully
charge it as outlined in the beginning of the Batteries section. The
Allegro will automatically restore the saved system and reset the time
on the Allegro. You are now ready to begin using the Allegro again.
NiMH Battery Pack's Useful Life
Battery packs can be recharged approximately 600 times before they
need to be replaced. This is dependent on the temperatures they have
been exposed to, operating conditions, and charging and discharging
practices.
Recycling the NiMH Batteries
The NiMH batteries inside the Allegro battery packs are recyclable.
We are voluntarily participating in an industry program to collect
and recycle these batteries when they are taken out of service in the
United States or Canada.
The recycling program provides a convenient alternative to placing
used NiMH batteries into the trash or the municipal waste stream.
Our involvement in this program is part of our commitment to
preserving our environment and conserving our natural resources.
Page 2-32 Hardware Features
The NiMH batteries inside the Allegro battery packs ar e recyclable. W e
encourage you to find a business in your area that provides battery
recycling bins for public use as an alternative to placing used battery
packs into the trash, thus conserving natural resources and preserving
the environment.
Spare NiMH Battery Packs
Spare battery packs should be stored in a cool location. Avoid placing
battery packs “contact side” down on a metal surface. Also, do not
stack packs so that their contacts touch one another. These practices
will cause the batteries to drain. The shelf-life of a battery pack is
about two months. Before using a spare pack, you should charge it.
▲▲
▲ Short-Term Backup Supply
▲▲
The Allegro has a super capacitor that behaves like a backup battery.
When the main batteries are removed, the capacitor maintains the
RAM for up to five minutes, allowing you plenty of time to change the
batteries. The capacitor cannot operate the Allegro. The capacitor is
charged by the batteries. It holds a charge as long as the batteries or
external power are supplied. When a battery pack is replaced, the
capacitor charges up to full capacity in about two minutes.
If power is not supplied to the Allegro for more than five minutes, the
Allegro resets when the battery pack is replaced or charged. All the
programs, data, and applications saved to the disk (C_Drive) are safe.
Information that was not saved to the disk is lost.
The super capacitor should not need replacement through the life of
the Allegro.
▲▲
▲ Real Time Clock
▲▲
The Allegro does not have a backup clock. You will need to reset the
clock on the Allegro when the Allegro’s power completely stops for
over five minutes.
Hardware Features Page 2-33
Communication Ports
The Allegro CE has five possible communication ports:
❏ T wo 9 pin serial ports (located on the top of the case)
❏ One infrared port (on top of the case)
❏ One USB port (available through the optional USB/Power Dock)
❏ One internal expansion port (available for most expansion pods)
Some of these ports are recessed to protect them in case the Allegro is
dropped. They are also completely sealed.
▲▲
▲ 9 Pin Serial Communication Ports
▲▲
The standard 9 pin serial communication ports (COM1 and COM2)
allow for the simultaneous operation of two serial devices such as
printers, modems, and bar code wands. Additional power is
provided on COM1 to power bar code wands and other sensors. The
data transfer rate on these ports ranges from 300 baud to 115 Kbaud.
Rubber connector protectors keep dirt and moisture out of the ports.
The ports are sealed without the protectors.
Be sure to use the serial communication cable (9 pin to 9 pin)
included with the Allegro to connect the Allegro to a desktop PC. A
wiring diagram of the cable is shown in Chapter 5, Technical Reference.
Note that a standard ‘straight through’ serial cable will not work.

Connecting Sensors to COM1
Pin 4 (DTR) on COM1 supplies up to 200 mA at +5 volts to power bar
code scanners and other sensors. This signal (DTR) must be set high
by the application to take advantage of this feature. When the DTR
signal goes low, the output is -5 volts. Insure that the device
connected to the DTR line can accept negative voltages or is protected
against them (standard RS-232 signal levels).
▲▲
▲ Infrared Communication Port
▲▲
The infrared wireless communication port (IrDA) located on the top of
the Allegro case allows you to send data to a printer or another
computer with an IrDA port without the need for a cable. The IrDA
port adheres to the Infrared Data Association Standards. The infrared
COM port runs at the speed of 115 kbps.
< IrDA Port
The IrDA port is used to connect the Allegro and a desktop or laptop
computer together to run ActiveSync, which allows you to transfer
and copy files between the computers and manage the Allegro files
remotely. Files can be sent from the Allegro directly to a printer with
an IrDA port from programs that have printing capabilities built-in,
such as Pocket Word.
The Allegro and the other device communicating with it via an IrDA
port need to be placed less than one meter apart with their infrared
ports aimed right at each other (within 15 degrees in any direction).
▲▲
▲ USB Communication Port
▲▲
The USB communication port located on the base of the Allegro case
allows you to send data to a desktop PC with a USB connection. The
USB COM port runs at standard USB speed (12 mbps).
The USB port connection is to be used with USB/Power Dock, and is
discussed in detail in the USB/Power Dock section of this manual.
Hardware Features Page 2-35
USB/Power Dock (Optional Hardware)
Using the USB/Power Dock you can quickly
transfer and synchronize files between the
Allegro CE and a PC. The Allegro charges
while it is docked, preparing it for tomorrow’s
work day. Multiple USB/Power Docks can be
attached to one PC using our USB MultiSync
function.
The USB/Power Dock is an optional two
function component designed for the Allegro
CE. It is a charging base and a communication
base. The Power Dock is ordered separately for
the Allegro CE. The Power Dock has three LED
(light) indicators on it, with the function of
each LED represented below:
Function LED Color
Power Supply Green
USB Communication Red

▲▲
▲ Power Supply
▲▲
The Power Dock uses the wall adapter that comes with the Allegro
CE. Looking at the back of the Power Dock you will see the 12 VDC
adapter connection on the right. Plug the Allegro power adapter into
the Power Dock and then into the wall. The green LED indicator
lights up showing the Power Dock has power.
▲▲
▲ Charging
▲▲
The Power Dock is a charging device for the Allegro. By placing the
Allegro into the Power Dock, the Allegro will automatically turn on
and begin charging. When the amber LED turns off the Allegro is
finished charging. The amber LED indicator lights up showing that
the Allegro is properly seated in the Power Dock and that the Allegro
is charging. The charging time is the same whether the Allegro is
turned on or off.
Page 2-36 Hardware Features
▲▲
▲ USB Communication
▲▲
The USB/Power Dock also serves as a USB connection from the
Allegro to the desktop PC. The red LED indicator lights up when the
USB connection between the Power Dock and desktop PC is active.
The connection and communication between the desktop PC and the
Allegro is achieved through ActiveSync. The USB port is used for
connecting both single or multiple units.
USB/Power Dock Connector Pins
The interaction between the Power Dock and Allegro happens
through the connection of the six connectors on the bottom of the
Allegro. There are six pins in the Power Dock that touch the Allegro
connectors as the Allegro is placed into the Power Dock. The six pins
can be replaced if damaged or bent.
▲▲
▲ USB Connection
▲▲
To establish a connection between the Allegro and desktop PC follow
the directions in Chapter 4 in the section entitled, Establishing a
Connection Using ActiveSync.
Once you have set up and successfully connected to ActiveSync for
the first time, you only need to place the Allegro into the Power Dock
and it will automatically begin the ActiveSync connection sequence.
Hardware Features Page 2-37
Multiple Allegro USB Connections
ActiveSync is a single unit connection program, resulting in only one
Allegro connecting to the desktop PC at a time. The USB MultiSync
feature automatically tells all connected Allegros to randomly begin
the connection process. If an Allegro is already connected to the
desktop PC, the other Allegros cancel the connection process and
wait a few minutes to retry a connection. This cycle continues until
each Allegro has connected to the desktop PC and all files have been
synchronized.
▲▲
▲ Using USB Hubs for Multiple Connections
▲▲
Because the average desktop PC only has two to three USB ports on it,
you need a USB hub for connecting multiple Allegros to the desktop
PC. You can purchase a 7-port USB hub through a computer store or
our Sales Department.
To connect the USB hub to the desktop PC follow the connection
instructions that come with the USB hub. To connect multiple USB
hubs to the desktop PC, plug the additional hubs into the first hub
and then plug the Power Docks into those hubs. Simply continue this
process until you have enough USB ports for the number of Allegros
you will be connecting to the desktop PC.
The USB/Power Docks can be connected to the hubs and PC in any
order. There is no fixed connection pattern required.

PC Cards
The Allegro CE has a user-accessible PC Card Slot (PCMCIA 2.0 Type
II) that allows you to add mass data storage and I/O capabilities to
the Allegro.
▲ ▲
▲ Types of PC Cards Accepted
▲ ▲
The PC card slot accepts Type I or Type II cards. These cards include
ATA Compact Flash cards, SRAM (Static Random Access Memory),
or Input/Output cards. All types have a 68 pin connector for
attachment to the Allegro. The cards must be 5 V or 5 V/3 V (PC cards
that are 3 V only are not supported). The PC card slot is a 16 bit card
slot. It is not a “card bus” slot.
Memory Cards

Internal Memory
The Allegro CE's internal memory is configured much like the
memory in laptop computers. It consists of ROM (Read Only Memory)
and RAM (Random Access Memory).
▲▲
▲ Read Only Memory (ROM)
▲▲
ROM is used to store the Operating System and Utility programs.
Information in the ROM is electronically “burned” into a chip before
the chip is installed at the factory. Information stored in ROM can be
read or copied. It can only be altered with a special utility program
provided by the factory. The information stored in ROM remains
intact whether the system power is on or off.
▲▲
▲ Random Access Memory (RAM)
▲▲
The Allegro has various sizes of internal RAM. Often referred to as
the computer's workspace, RAM is where programs are executed or
run. RAM can be written to, read from, erased, etc. Its storage ability is
temporary in nature, only holding information while the system has
power (although the Allegro does not have to be turned on). If the
battery pack is drained or power is interrupted for any reason,
everything stored in RAM is lost. The backup capacitor saves the
contents of RAM for a limited time while you change the battery pack
(see Chapter 2, Batteries, for details). You can use the Save System
utility to save the RAM file system and registry. Refer to Chapter 4,
Windows CE, System Save/Restore Utilities.
To see how much RAM is available for your use, tap on Start and
select Settings|Control Panel|System|Memory. Subtract the In Use
figures from the Allocated figures. From this screen you can adjust the
amount of RAM that is allocated for storage memory versus program
memory.
If you try to save a file that is too large for the amount of RAM that
has been allocated to storage memory or run a program that
requires more execution space than you have allocated to program
memory, an error message is displayed.

We recommend you use the internal non-volatile data storage as your
primary storage area. This is because the information is retained
without power. (ATA Flash and Compact Flash cards are also nonvolatile.)
▲▲
▲ Internal Non-Volatile Data Storage
▲▲
The Allegro CE has a solid state storage drive used to store programs
and data. It can be read from and written to just like the hard drive on
a PC. The solid state internal storage is non-volatile so information
stored on it is retained even when no power is supplied to the
Allegro. The solid state storage is an internal drive and is not user
accessible.

Page 3-4 Memory and Data Storage
PCMCIA stands for the Personal Computer Memory Card
International Association. This association has developed standards for
PC cards. PC cards are about the size of a credit card and come in
three thicknesses or types.
The PC card slot accepts Type I or Type II cards. These cards include
ATA Flash cards, SRAM (Static Random Access Memory), and
Compact Flash adapter cards. All types of cards have a 68 pin
connector for attachment to the Allegro. The cards must be 5 V or 5 V/
3 V (PC cards that are 3 V only are not supported). This is a 16 bit
card slot. It is not a “card bus” slot.
A PC memory card is a solid state, self-contained memory board
housed in a credit card-sized package. These cards behave like hard
drives. You can read from them, write to them, and erase single files
from them. There are several types and brands of cards available.
ATA Flash Cards
ATA Flash cards provide solid state data storage. Power is not
required to maintain the data, and because of this feature, we
recommend them over other types of memory cards. The Allegro
accepts cards ranging in size from 1 M to 100+ M, with larger cards
available.
Formatting ATA Flash Cards
ATA Flash cards come pre-formatted.
Memory and Data Storage Page 3-5
SRAM Cards
Power
SRAM cards are powered by the Allegro while installed in the PC
card slot. An on-board battery retains data when the card is not being
powered by the Allegro. Some brands have a replaceable lithium
battery (coin type). If you have this type, make sure that the battery is
installed before attempting to use the card. Other brands have a
rechargeable battery that is automatically recharged while it is inside
the Allegro. The rechargeable batteries are not replaceable.
The life of these batteries varies greatly depending on usage and the
memory size of the card. If the lithium battery in the card is drained,
the information stored on the card is lost. When a new battery is
installed, the card needs to be formatted. The manufacturer's
instructions that came with the card includes information on battery
life and recommended charging intervals.
Replacing SRAM Card Batteries
SRAM card batteries are readily available at most stores. Unless the
manufacturer's instructions state otherwise, we recommend that you
change the battery every six months.
Formatting SRAM Cards
SRAM cards come pre-formatted. Files and directories can be copied
onto it just like a standard disk drive.

Windows CE Overview
This chapter describes the operation of the Allegro CE using
Microsoft™ Windows™ CE (3.0 and CE .NET). Each operating systems
has a similar look and feel to a desktop PC Windows operating
system. Windows CE is designed for small, portable hand-held
computers like the Allegro. Windows CE gives the Allegro the ability
to communicate and share information with Windows-based
computers and the Internet by using ActiveSync.
Windows CE offers the following features:
❏ Compact operating system and application file sizes
❏ Advanced power management
❏ Communication flexibility
❏ Graphic user interface similar to Windows 98/2000
❏ Packaged programs, including PT ab Spr eadsheet, Pocket W or d,
and Internet Explorer
❏ Multiple applications can run simultaneously
Windows CE has the same Windows interface you are familiar with if
you have used Windows on your desktop PC. You will find that you
already have much of the knowledge you need to use Windows CE
effectively. This chapter was written with the assumption that you
have a working knowledge of Windows.
▲ ▲
▲ Starting Windows CE
▲ ▲
The first time you insert the battery pack into the Allegro you must
fully charge the batteries (see the Quick Start Guide). While the
Allegro is charging, you can turn it on. The Allegro loads and opens
to Windows CE. It takes a moment for the desktop to appear and
remain on the display. Various screens appear during the loading
process that do not require any action.
Windows CE Page 4-3
The Windows CE Desktop appears on the screen:
Suspend/Resume Mode
If you press the On/Off key, the Allegro goes into suspend mode.
When you turn it back on, it resumes in the same place it was at
before you turned it off. For example, if a PTab spreadsheet file was
on the screen when you turned the Allegro off, the same spreadsheet
screen appears when you turn the Allegro back on. (If the batteries are
drained or left out of the Allegro for more than five minutes, the
Allegro restarts instead of resuming. Refer to the Chapter 2 section
entitled Batteries for details.)
▲ ▲
▲ Display Touchscreen
▲ ▲
The display has a touchscreen used to activate programs in Windows
CE and to make selections. The touchscreen works similar to a mouse.
Page 4-4 Windows CE
Three styli are provided: two small on-board stylus and a full size
pen-type stylus. The small on-board stylus snaps into a holding bay
built into the top of the Allegro. The Allegro can only hold one onboard stylus at a time. Other pointed objects can be used, including
your finger. Be sure to use a device that will not scratch the screen.
Calibration
To calibrate the touchscreen and set up the screen-tap sensitivity,
refer to Windows CE, Control Panel, Stylus later in this section. If you
have trouble selecting an item when you tap on it, the touchscreen
may need to be calibrated.
Touchscreen Operation
Use the following techniques to operate the touchscreen:
- T ouch the screen at the desir ed location, just as you would point
and click with a mouse.
- T ap on the scr een once to achieve a single click or twice to achieve
a double-click.
- A right mouse click is accomplished by holding down the Alt key
and tapping the screen.
- Drag and drop items by touching and holding the item on the
screen, dragging the stylus to the desired location, and removing
the pointing device from the screen.
Wiping Off the Touchscreen
When the touchscreen gets wet or dirty, a natural inclination may be
to wipe across the display with a shirt sleeve or your hand. If you do
this while the Allegro is running, you may inadvertently press items
on the screen. To avoid this problem, the Allegro is equipped with a
special Touchscreen Disable/Enable key described below.
+
The unique Touchscreen Disable/Enable key allows you to temporarily
disable the touchscreen and wipe it off without inadvertently making
selections on the screen. Press the BLUE shift key and the TS key to
disable the screen. The contents of the display are still shown, but
nothing happens if you press on the touchscreen.
Windows CE Page 4-5
Ideally, use a soft, clean cotton cloth to gently wipe off the screen. Do
not use anything abrasive that could scratch the screen, including
tissues and paper towels. (The tail of your shirt will do, as long as it
is made of a non-abrasive fabric) Once the screen has been cleaned,
use the same key sequence to enable the touchscreen. Refer to the
Chapter 2 section entitled Display for more details.
