2 Description
The GPT-4454 is an industrial printer for installation in
a robust plastic housing reinforced with fiber glass.
The foil on the operating console can be printed with
a custom design.
Due to the extended temperature range of -10 to +60
°C, MAXI MULDE is ideal for outdoor applications.
Easy paper roll exchange due to Easy Paper Loading
technology. The paper supply lid closes securely shut
(tested in accordance with DIN EN60068-2-6 vibrati-
ons, and -27 shock).
A convenient OnPaperDisplay menu (OPD-Menue®)
replaces the earlier configurating of the printer
through DIP switches
.
Besides wireless interfaces such as Bluetooth®, IrDA,
or GeBE-Ir, MAXI MULDE can also be controlled
through a RS232 or USB interface.
The printer can be equipped with a battery charging
circuit for 5 NiMH cells or 2 Li-Ion cells. Charging will
take about 4 hours.
Intelligent power management increases the operatio-
nal readiness. The printer can switch to a sleep mode
that will still allow it to receive data. In sleep mode,
the power consumption can be lower at times than
the self-discharge of the battery.
The alarm timer of the optional real time clock of the
MAXI MULDE wakes up the printer at the program-
med time to perform a previously defined action.
The GPT-4454 is also available with a 3-track mag-
netic card reader and/or a paper rewinder.

4 Installation
4.1 Installation in a Front Panel
The printer GPT-4454 can be installed with two screws in an easily done front
panel cut-out of with a thickness of up to 4 mm. The contact surface is flat. The
edge of the housing juts out by 1 mm, covering the space between the housing
wall and the panel and the plastic housing.
The plastic housing is pushed into the cut-out from the outside. Then, it can be
easily mounted to two mounting plates.
The two 2.8 mm holes allow the use of M 2.5 screws.
4.2 Partial Installation in Plastic Housing
As shown in the picture on the left, the printer housing can also be installed
at the edge of a casing. This installation variation has the part of the printer
housing that contains the paper roll extending beyond the unit casing. This
saves room in the device casing for the installation of other components.
To facilitate installation in different casing shapes, the outer wall of the pa-
per storage was left smooth below the bearing collar. The housing can pro-
ject about 19 mm from the casing edge, since about half of the paper stora-
ge can be used, right up to the slanting slot for inserting the mounting pla-
te.

5 Connection • Installation
5.1 Power Supply
The printer can either be supplied with a fixed voltage
from a power supply or from a battery.
5.1.1 Fixed Voltage Operation with integrated
DC/DC converter 10 - 18 VDC or 18 - 36 VDC
The GPT-4454-DC/DC has an integrated DC/DC con-
verter with an input voltage range of 10-18 VDC or 18-
36 VDC, depending on the type. The DC/DC supply is
connected to socket 10 (see pictures in chapter 2).
The voltage inputs are protected against reverse polari-
ty and secured through a PTC. The connected voltage
supply has to be protected against overvoltage in ac-
cordance with EN/IEC 60950. Suitable power supplies
for these variants are available from GeBE.
5.1.2 Operation through 4.5 - 8.5 VDC Fixed
Voltage or Battery
In order to comply with EN/IEC/UL60950, the power
supply may ONLY be connected with the cable GKA-
517 and MUST meet the requirements for power supp-
lies for limited power due to design. For installation con-
forming to standards, please also regard the instructi-
ons of the UL60950 and in our manual SMAN-E-529.
Only the battery GNA-6,0V-1,6Ah-NiMH-Pack-070
may be connected.
Battery or power supply are connected with the same
connector 12 (3 red wires for +4.5/-8.5 VDC, 3 black wi-
res for ground, and one white wire for an NTC 6.8
KOhm of a Ni-MH battery; see pictures in chapter 2).
For a simple power connection, the white cable has no
function. It is recommended to keep the length of the
line as short as possible. A line that is too long has a
high line resistance, causing bad print quality, and pos-
sibly even printer failure.
The battery pack consists of 5 cells NiMH Mignon (AA)
with 1,600 mAh. A temperature sensor monitors the
battery temperature during the charging process. An in-
tegrated bi-metal over-current circuit breaker protects
against short circuits and overheating.
The battery charging voltage is connected through so-
cket 12 (see pictures in chapter 2). The specified plug-
in power supply is attached to the connecting cable and
During installation:
Always disconnect the power!
During installation and operation, the user
(service operator) must abide by the regulati-
ons regarding IEC 60950-1:
Protection against contact with high-volta-
ge parts and compliance with the require-
ments regarding insulation.
the matching connector.
With a fully charged 1,600 mAh battery, up to about 40
m of thermal paper can be printed with normal text.
5.1.3 Installation of an External Battery
For installation of batteries, the following guidelines ap-
ply:
- When a battery is installed, sufficient surface area for
heat dissipation is essential.
- The battery has to be mounted stationary.
- Only batteries from GeBE or authorized by GeBE may
be used.
- The cables have to be mounted unstrained.
5.2 GPT-4454 Power Management
Whenever there are no data to process, the printer will
automatically switch to idle mode. In this mode, it acts
100% active and can receive data without delay. The po-
wer consumption in this mode is typ. 5 mA.
Sleep Mode
If a sleep time has been set via menu, the printer will
switch to the power-down mode after the expiration of
this time. Any kind of data transfer (even infrared), activi-
ty on control lines, connecting the charger, or simply the
pressing of the FEED/ENTER button will reactivate the
printer immediately without the loss of any settings. Only
the print buffer is erased. The necessary activation and
waiting for the apropriate ready message from the prin-
ter has to be accounted for in the printer drivers. The po-
wer-saving sleep mode can be turned on or off through
the following functions:
• settings menu
• command from the host or from the batch file TINIT
Power Off
When the"OFF/NEXT" button is held down for more than
three seconds, the printer is completely turned off. It is
turned on by pressing the FEED/ENTER button, or by
connecting the charger. Optionally, the printer can be
configured, so that it can also be turned on through the
RTS line.
5.3 Charging the GPT-4454
The GPT-4454 has an intelligent charging circuit without
current limitation. The current limitation is ensured
through the use of the included power supply.
The charging process is divided into three steps.
The use of a charger other than the one included
in the deliery may cause damage to the printer.
The recommended temperature range for battery
charging is between 10 and 25 °C.

Formatting Charge
If the battery is overdischarged, a formatting charge
with a low voltage is started to avoid damage to the
battery. The formatting charge is not displayed on the
outside. The formatting process can take from 1 to 15
minutes, depending on the state of the battery.
.
Fast Charge
As soon as the battery voltage exceeds the operating
voltage of the printer, the printer starts the fast char-
ge. This is indicated by a slow flashing of the STA-
TUS LED, and by a message through the interface.
The charging process takes about four hours for
empty batteries.
Trickle Charge
As soon as one of the stop criteria has ben reached,
the printer will switch to the trickle charge. In this
mode, a permanent formatting current is flowing. In
addition, the fast charge is activated every eight mi-
nutes for 20 seconds. This is indicated by permanent
glowing of the STATUS LED and by a message
through the interface.
5.3.1 How to Handle Batteries
The capacity of a battery gradually decreases due to
usage, tough environmental conditions, aging, and
lack of maintenance.
Just like any other battery technology, NI-MH batte-
ries require some care in order to achieve the maxi-
mum life and to preserve the power as long as pos-
sible. Without this care, the cells will quickly become
highly resistive with their capacity noticeably decrea-
sing. In high current applications like thermal printers,
Ni-MH batteries reach about 500 charging cycles ma-
ximum. However, the available energy starts to dis-
tinctly diminish from about 200 - 300 cycles.
The Correct Handling of a Ni-MH Battery:
Charging:
NI-MH batteries are extremely sensitive to any kind
of over-charging. A trickle charge should only be
applied, if at all, with very small currents and for short
periods of time.
For technical reasons, the printer needs to be sup-
pied with a very small charging current at all times.
Therefore, it is recommended to disconnect the prin-
ter from the printer as soon as possible, after the
charging process was completed. Never charge bat-
teries outside the temperature range of 10 to 25 °C.
Overdischarged Batteries:
The printer will initially format overdischarged batte-
The inserted batteries require at least 3 com-
plete charging and discharging cycles in order
to reach their maximum capacity. Incomplete
charging and discharging cycles during opera-
ting will reduce the life of the battery.
ries with a small charging current. For very strong di-
scharges, this process can take up to 30 minutes. This
status will not be indicated by the printer. At the begin-
ning of the fast charge, the printer will flash 1:1. For
overdischarged batteries, an effect develops at the be-
ginning of the fast charge phase that is similar to the
turning-off criteria of a full battery. For this reason, it
may come to an early shutdown in rare cases. There-
fore, we recommend to check for overdischarged batte-
ries after about 30 minutes, whether the fast charge is
still running. If not, please start the charging process
over by unplugging and plugging back in.
Discharging/Printing:
If Ni-MH batteries get overdicharged with high currents,
the polarity of the weakest cell will be reversed. This re-
versal will cause damage to the cell and, in the worst
case, will lead to a short-circuit in the cell. Should your
printer refuse to print because of an empty battery, you
should not continue trying. Any further attempt may
lead to a reversal of polarity in a cell and therefore, to
the distruction of the battery.
Storage:
NI-MH batteries have an increased self-discharge.
They lose 10-15% of their capacity during the first 24
hours after the charging process, and after that, 10-
15% per month.
Therefore, the printer should be turned off, whenever it
is not being used for longer periods of time. This is
especially true for devices with Bluetooth technology.
Nevertheless, the printer will have to be recharged after
no more than 3 months, or the battery may get dama-
ged.
Always store the battery with a charging state of > 50%
and in a temperature ranging between 10 and 30 °C.
Regeneration:
If NI-MH batteries have not been overdischarged, they
may indeed regenerate. To achieve this, the battery has
to be discharged completely for about 50 charging cy-
cles (3 months).
For this purpose, you can turn off the sleep function
and let the printer discharge the battery. As soon as the
printer shuts down due to low voltage, the battery
should be charged immediately.
Do not print to speed up the process. This may
cause the polarity of one cell to reverse, destroy-
ing the battery. Do not forget to reactivate the
sleep mode afterwards.

RS232 Interface
The interface cable that comes with the set connects to
the plug-in connector 11 (see chapter 2), and directly
with an RS232 connection (COM interface of a PC) on
the other end. An open-ended cable with 5 single wires
is available as an option.

Serial RS422/485 Interface
By mounting the GCT-4482-10 module, an RS422/485
interface can be installed at the serial connectors. With
the solder bridges Br1-5, the interface can be configura-
ted as RS422 or RS485. Br6 activates a 120 Ohm ter-
minating resistor for RS422 systems.
GeBE COM
In this setting, the printer uses the GeBE-Ir protocol for
communication. The protocol can be used either
through the RS232 or the TTL interface.
Due to the CRC guarded transmission blocks, a secure
data connection can be used (also see: Infrared Interfa-
ces).

Interfaces • Infrared Interfaces10
GeBE E + F GmbH • www.gebe.net • GeBE Dok.Nr.: SMAN-E-510-V1.5 Thermal Printer GPT-4454
The following protocols can be used:
• IrDA: IR LPT (printer service)
IR COMM 9 wire (optional)
Also see: www.irda.org
• GeBE-IR: simple, error-proof,
bidirectional,
dot-to-dot IR protocol.
GeBE-Doc.No. MAN-D-394
All standard versions of the printer have the hardware
for an IR transmitter/receiver installed, so the protocols
GeBE-IR and IrDA are available for all standard printers
of the series GPT-4454.
The internal IR tranceiver is installed directly below the
red foil window (10). It is important to consider that inf-
rared transmission only works "at sight". The radiation
angle is about ±15 degrees. The transfer distance to
"IrDA standard power" devices is 1.0 meter.
Use of the Sleep Mode
In the setting "IrDA "or "GeBE IR", the IR receiver will
even stay active in the sleep mode, so the device will
not have to be swiched on explicitly for printing. The po-
wer consumption of the printer is only about 25µA in
this mode. However, the printer should still be turned off
during long periods of inactivity.
GeBE -IR Protocol
The GeBE-IR protocol is a simple, error protected infra-
red protocol. Data transmission is processed in CRC
protected blocks.
With each transmission confirmation, the printer status
is sent back to the host.
The implementation is very easy to realize. The protocol
is disclosed.
IrDA Protocol
The printer works with the protocol service IrLPT. In this
service, the printer will not send back any messages.
A bidirectional service "IrCOMM 9 wire" is available on
request.
In the menu setting, the selected baud rate represents
the maximum baud rate. If 57,600 baud is selected, for
6.3 Infrared Interfaces
example, the printer will start to communicate with
9,600 baud and then switch up to 57,600 or 38,400
baud, depending on the transmitter.
The maximum baud rate of 115,200 should only be re-
duced, if transmission errors occur.
When an infrared transmission is interrupted, the printer
will look for the transmitting master device for about 20
seconds in order to complete the transmission. After
that, the stack is reset, and new inquiries are answered.
