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.
6 Interfaces
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).
Pin Assingment of the Serial Interface RS232 at Connector (11)
Plug-in connector at the printer: (5pin). >>> serial cable. The second end has a 9 pin SUB-D socket.
The assignment is 1:1 matching the COM interface of the PC.
Timing of the serial RS232
The preset timing by default can be seen in the diagram.
For the printers with EEPROM, the data format can be set via settings menu.

The peripheral devices that are connected to
the interfaces and the DC circuits of this
printer have to meet the requirements for
extra-low safety voltage (SELV) with limited
power in accordance with EN/IEC 60950.
