Interface cable GKA-406, included in sets 1 and 2, is connected to the connector J2. For RS232 versions, this
cable can be directly connected to a PC. A cable with 5 single wires and one open end is available as an option.

The printer GPT-4352-LV-82-IR-EVAL has an internal IR-tranceiver directly under the red foil window of the control
panel. If the infrared interface adapter GCT-4382-20 is connected using the cable GKA-408, the internal tranceiver
will automatically turn off.

On the GPT-4352-LV-82-TTL(4,5V)-EVAL, the RS232 interface driver is not integrated, but the TTL signals of the
UART are directly ground through to J2. This enables the connection of opto isolated interface adapters for
RS232, RS422/485, and TTY.

Connecting the battery charger (3)
EVAL printers have a standard charging circuit for 4 Ni-MH
cells. An operation with 3 or 5 cells is also possible. The char-
ging is performed by the uncontrolled plug-in power supply
GNG-6V-0,5A-U that has a special internal resistance. It is
connected through the cable GKA-416 to the connector J1.
The charging time for a 1200 mA/h battery will be about 5
hours.During the charging process, the LED on the control
panel will display different pulses that show, whether the fast
or trickle charging mode is active.

The printer can be supplied with fixed voltage from a power supply or a battery. Battery or power supply are
plugged into the same connector. Through the voltage supply connection, the printer can be supplied with vol-
tages between 3.5 V (for printers with Centronics adapters with 4.5V) and 7.2 V. The supply for the logic chip is
produced on the board. The power cable GKA-410, included in sets 1 and 3, is connected to the connector J4
(3 red wires for + 3.5 -7.2 VDC , 3 black grounding wires, and one white cable for an NTC 6.8 KOhm of a Ni-
MH battery). For simple power connections, the white wire remains unconnected. We recommend keeping the
length of the line as short as possible. The longer the line, the higher the line resistance, causing bad print qua-
lity or even printer failure.

refully check the power supply connection before you turn on the printer.

Starting with hardware version V1.4c the standard version does not support the power-off mode.
The controller comes with different levels of power saving modes (power down modes):
• idle mode (8 mA typical)
• sleep mode (20 ±A typical)
• power-off mode (0.1 ±A typical), optional configuration requi-
red
During the receiving of data and during printing the controller is
in an active status.
With the parallel interface, the ballast resistor R35 is not part
of the standard configuration.
Connect jumper J3 for idle mode.
Remove jumper J3 for sleep mode.
Power-off logic ist not in the standard configuration (replaced
by R37).

Never use a fixed-voltage power supply for charging the batteries. The charging circuit is a
"simple switch control", meaning that the current limitation is not done in the charge control of the
printer, but in the plug-in power supply.
Please use the suitable GeBE power supply GNG-6.0V-0,5A-U.
