Data Interfaces
Options for Connecting Peripherals
You can connect the following printers
to the COM1 and UniCOM interfaces:
– YDP02 (user-definable interface
parameters)
– YDP03 (user-definable interface
parameters)
– YDP01IS (strip or label printer)
– YDP02IS (strip or label printer)
– YDP04IS (strip or label printer)
– Universal printer (user-definable
transmission parameters)
– YAM01IS Alibi memory
The following devices can also
be connected to the COM1 interface:
– Foot switch / hand switch
– PC (RS-232 interface)
– Second weighing instrument
(Combics 2 only, RS-232 interface)
– External checkweighing display
(red/yellow/green) over the digital I/O
(Sartorius standard)
The connector of the UniCOM
universal port enables the following
devices to be connected:
– External rechargeable battery pack
– Bar code scanner (Combics 1 plus and
Combics 2 only)
The following devices can also
be connected to the UniCOM universal
interface:
– PC (RS-232 interface)
– Second weighing instrument
(Combics 2 only; can be switched from
RS-232 to RS-485 operating mode)
– Second printer (external power
source required)
– Remote display
– Current interface (0/4 - 20 mA)
!
If necessary, use an external power
source to power peripheral devices.

Connecting a second weighing
instrument:
Combics 2 enables connection of
a second weighing instrument to either
the COM1 or the UniCOM port.
COM1 operates in RS232 mode.
A second weighing instrument on this
port can use the following operating
modes:
– SBI
– XBPI-232 (factory setting)
– ADC-232
UniCOM can operate in either the
RS-232 mode or in RS-485 mode.
A second weighing instrument on this
port can use the following operating
modes:
– SBI (RS-232 mode)
– XBPI-232 (RS-232 mode)
– ADC-232 (RS-232 mode)
– IS-485 (RS-485 mode, XBPI mode;
factory setting)
– ADC-485 (RS-485 mode)
Connecting a Printer
The standard COM1 port or the optional
universal UniCOM interface (or both)
can be used as a printer interface.
Operation as a COM Port
For operation as a COM port,
you can adapt the data protocol to the
following operating modes:
– SBI (factory setting)
– XBPI-232
– XBPI-485 (only UniCOM)
– MP8-binary (only COM1)
– SMA
You can operate the COM1 port and
the UniCOM port independently of one
another (i.e., for transferring data and
controlling equipment via a PC while
simultaneously outputting data to the
COM1 printer port).
In the SBI communication mode,
you can control a display unit and
a connected weighing instrument
by sending ESC commands from
a PC to the communications port
(COM1 or UniCOM) (see page 96).
!
When using two interfaces (COM1 and
UniCOM) each device can be configured
only once. Devices are as follows:
– WP1-2
– Data communication
– External Alibi memory
– Analog output port
If you attempt to configure a device a
second time (e.g., for the UniCOM port)
after it has been configured another
port (e.g., "Data communication" on
COM1), error code INF 74 is displayed.
