When using the DWT7133:
- for the first time,
- after a long period of disuse,
it is strongly recommended to
charge the terminal on the cradle
for at least 15 hours. After this use
the terminal untill it is fully
discharged.
Although the DWT7133 can operate
on a partial first charging, at least one
full charge is needed for optimum
battery condition and accurate battery
status monitoring.
When the terminal switches off due
to an empty battery, it should be
placed on the cradle.
A fully charged backup battery will
safeguard the data in the RAM for at
least one week. Within this period data
the main battery in the terminal must
be charged, otherwise data may be
lost.
General function
When the main battery of the DWT runs empty,
the terminal is switched off automatically. The
collected data inside the RAM memory is at
this time preserved by the backup battery.
When the backup battery is full, the DWT7133
will keep its data for at least one week. The
application program is stored in Flash-ROM
and will always be preserved, regardless of the
status of the batteries.
Warning levels / Charging indicators
It might be possible to use your own warning
levels for the battery capacity or to set your
own indication for the charging process in
your application program. Consult the
documentation of your application program.
!

1.5 BATTERY CHARGING
User programmable
The DWT7133 is user programmable with the
C-programming language (ordered as C-library
and C-compiler). It enables you to develop and
upload data storage and data processing
applications conforming to your own
requirements and preferences.
Supports all popular bar code symbologies
Auto discrimination among all popular bar
code symbologies. This offers you flexibility in
bar code applications.
User friendly
The terminal contains a real time clock. Visual
assistance is provided on an LCD display. User
programmable indicators such as the beeper
and the LED provide audible and visual
feedback to the user. A good read, for
example, can be highlighted by a beep and
the lightup of the LED.The DWT7133 will
switch off automatically after the last operation
(deactivation time is programmable, default 30
seconds).
Rechargeable battery
The DWT is equipped with a rechargeable
Nickel Metal Hydride battery pack, that allows
long operating time. In addition, a rechargeable
Lithium backup battery safeguards the data
when the main battery is empty.
Contactless battery charging and data
transmission
There is no direct electrical contact between
the cradle and the terminal. Optical data
transmission technology and inductive charging
technology is used. The eliminiation of worn,
corroded or dirty contacts assures safety and
reliability.
Outdoor use
The terminal is ideal for numerous
applications and outdoor use because it is
robust, lightweight and water resistant.
1.4 CHARACTERISTICS OF
THE DWT 7133
Advise for normal use
After use, place the terminal on the cradle for
recharging. Keeping the terminal on the cradle
(for example at night) ensures that the battery
is regularly fully charged. This will keep the
batteries in optimum condition and will speed up
recharging.
Charging sequence
By monitoring the current flow into and out of
the main battery, the DWT7133 can provide
an accurate battery status indication and
optimise the charging performance.
The charging process can be controlled
accurately when the maximum capacity and
the current status of the battery are known.
These values first become available after a
complete charging and discharging cycle.
The main battery is normally quick-charged
until it reaches the level of 80%. The
remaining charge level up to 100% is charged
at a lower current, to keep the battery in
optimum condition.
The result is that the DWT7133 is quickly
available for use again, and the main battery
will be fully charged when the terminal is
placed on the cradle for a longer time (for
example at night).
CHARGE REGULARLY
Discharging
The “memory effect” of the Nickel Metal Hydride
battery in the DWT7133 can be neglected.
Therefore discharging the batteries is not
necessary.
Charging times
first charge approx. 15 hours
full charge approx. 4 - 15 hours *
normal charge
0 - 80 % (quick) approx. 2 hours
80 - 100 % approx. 2 hours
*) Note to avoid long charging times
Obtaining a full charge enables the
DWT7133 to determine more accurately
when to switch to a lower current. After a
long period of disuse, or after many partial
charges, the terminal will switch more early
to a lower current, resulting in longer
charging times (in extreme cases up to
14 - 15 hours as in first time use). The
recharging time is reset to normal as soon
as a full charge is reached again.

The cradle can be powered directly from the
AC mains voltage or from a DC voltage. For DC
voltage, you can use a 12 V stabilized
adapter.
Be sure that the mains voltage
corresponds with the cradle voltage.
When you choose a mains voltage
connection to the cradle (220 or 110 V AC):
1. Plug the rounded end of the power cord
into port04 on the back side of the cradle.
2. Plug the other end of the power cord into
an AC outlet.
When you choose a DC voltage connection
to the cradle (12 V DC + 10% stabilized):
1. Make sure that the polarity of the 12 V DC
connector is correct.
2. Plug the round connector into port03 on
the back side of the cradle.
3. Plug the adapter into an AC outlet or connect
the other end of the cord to the external
12V battery.
Data transmission from the DWT7133 terminal
to a host computer is achieved by using the
DCW9931 cradle. This cradle supports both
RS232 and RS485 communication, which
allows you to use the terminal in both single or
network mode.
An advantage of the RS485 interface over the
RS232 is the possibility to use terminals in a
network structure.

The functionality of the terminal is determined
by software, the so-called user application,
that is running on the terminal.
Usually, the terminal is not equipped with
software and has no functionality. At first the
user application must be loaded before the
terminal can be used for barcode scanning.
Tools for developing a user application on the
PC for use on the terminal, as supplied by
Opticon are: C language, consisting of
Microtec ANSI-C compiler and C library for
handheld terminals, or the DMC interpreter.
The user application must be downloaded
from the PC into the terminal. You can use the
cradle for communication between the terminal
and the PC. A program on the PC will send
the user application to the terminal, where it is
stored in FlashROM memory.
When the functionality of the terminal is defined
by the application it is ready for operation.
In a typical application you will press the trigger
key and scan a bar code label as described in
the next chapter. Scanned data and data
entered from the keyboard is stored in the
terminal's RAM. The user application can use
this data in subsequent steps.
The collected data can be transmitted to the PC
for further processing. For data transmission
you can use the cradle.
