Input
Bar Code Scanner or Keyboard Input
You can use a bar code scanner or an
external keyboard to input alphanumeric
values. These inputs are processed in
the same manner as keypad inputs on
the display and control unit of the bal-
ance. Bar code and keyboard inputs are
only displayed; they cannot activate any
function.
To assign a bar code scanner or
keyboard input to a function, press one
of the following soft keys:
– Lot
– Samples
– Measured values
– Sample number
– Tare value
– Initial weight
– Backweighed value
– Sample ID
Foot or Hand Switch Input
You can connect a foot switch or a
hand switch to the Genius balance to
have this device perform a keypad
function (such as c or t).
PC Input
You can use a computer to control the
functions of the Genius weighing cell
and display and control unit via the
communications port (see the "Data
Output Function" section in the chapter
entitled "Operating the Balance").

Data Output
The Genius balance provides two
interface ports for outputting weights,
calculated values and parameter
settings:
– Serial communications port
(PERIPHERALS – Serial I/O)
– Serial printer port
(PRINTER – Serial Out)
Serial Printer Port
In addition to Sartorius printers (such as
the YDO03-0CE), you also have the
choice of connecting a remote display
or an external checkweighing display to
the printer port.
You can configure the data output
functions in the Setup menu to meet
your various requirements, including
ISO | GLP requirements.
ISO: International Organization
for Standardization
GLP: Good Laboratory Practice
You can have printouts generated auto-
matically, or by pressing p/r ;
generation can be dependent on or
independent of the stability or time
parameters.
See the section on "Data Output
Functions" in the chapter entitled
"Operating the Balance" for a detailed
description.
Serial Communications Port
You can connect a PC, a remote display,
an external checkweighing display
or a standard (non-verifiable) printer
to this port.
Request messages are sent via the
interface to initiate functions in the
weighing cell and in the display and
control unit. Some of the functions
generate response messages.
See the section on "Data Output
Functions" in the chapter entitled
"Operating the Balance" for a detailed
description.
Error Codes
If you press a key that has no function,
or which is blocked at a certain point in
an application program, this error is
indicated as follows:
– a double beep is sounded as an acoustic
signal if the key has no function
– a double beep is sounded and the
message "No function" is displayed in
the text line if the key function is not
available at that time
The response to an operator error is
identical in all operating modes. See
the chapter entitled "Error Codes" for a
detailed description.
