Data Interfaces
Setting the SBI Data Output
Data output settings can be made in the Setup menu under “Data
communications:SBI:Data output."
The following options are available:
– The displayed value, with or without stability check
– Automatic output of the displayed value, either with or without stability check,
or automatically at defined intervals
– Output of a printout as configured in the “
Device parameters:
Config. printout:Printer 1" or “Printer 2" (see next page).
You can define the printout content by specifying which blocks of information are to be
included (see “Configuring Printouts”).
In general, the current display value is output (weight with unit, calculated value,
alphanumeric display) unless you configure a user-definable data record.
Generally, data is output only after the weighing instrument has stabilized (factory
setting). Here you can define whether data is output on request or automatically, at
stability or without stability check; and configure a user-defined printout. The data
output for “without stability" must be set accordingly (SBI: Data output).
If you select time-dependent automatic printout, you need to define the print interval
(in display updates) as well.
Each line of a printout can contain up to 20 characters. The first 6 characters, called the
“data header”, identify the subsequent value. Only 14 characters are available if you
disable the header. This is carried out in the “Line format" menu item (see also “Setup
Overview" in “Configuration").
Automatic Data Output (SBI)
You can have the weight readout printed automatically
1
). This printout can be generated
after a certain number of display updates
2
). You can also configure whether or not the
auto-print function is dependent on the stability of the scale
3
).
The display update frequency depends on both the scale model and the operating status.
Examples:
N + 153.00 g Net weight
Stat Display blank
Stat L Display underload
Stat H Display overload
"Data output" setting:
1
)
3
)Automatic, without stability or automatic with stability.
Factory setting: Manual after stability; i.e., automatic data output function off.
2
) Time-dependent automatic data output:
Interval: 1, 2, 10 or 100 display updates
Factory setting: 1 display update
Data Input Format
You can connect a computer to your scale to send commands controlling weighing
instrument functions and applications via the interface port.
All commands use the same data input format. They begin with the ESC (ASCII: 27)
character and end with a carriage return CR (ASCII: 13) and LF (ASCII: 10). The total
length of a command is anywhere from 4 characters (1 command character between
the start and end described above) to a max. of 7 characters (4 command characters).
This number can also be higher when sending texts.
The commands listed in the following table must each be supplemented with
ESC ... CR LF.
