Software Kern BalanceConnection: what’s new in 2019

Two versions of Kern’s BalanceConnection software are now available: the standard version (SCD-4.0) and the Pro version (SCD-4.0-PRO).

The following table shows the features of the standard version on the left and the additional features of the Pro version on the right (according to Kern’s 2019 catalog):

BalanceConnection SCD-4.0 BalanceConnection SCD-4.0-PRO
· For operating systems Windows XP, Vista, 7,
8, 8.1, 10
· Supports balances measuring devices with
RS 232, RS 485, Bluetooth, LAN or WLAN
network (TCP/UDP/IP)
· Highly flexible formatting of the output (any
order, formatting and rounding), particularly
recording of date and time for every value
transferred, if required
· Any number of devices/interfaces can be
connected, as well as simultaneous and
synchronised recording of several balances
· Key-activated or time-controlled interro-
gation of measurements or trigger of device
functions, also for continuous recording
· The interface protocols for KERN balances are
already predefined (standard configuration)
· Compatible interface cable included when
you order a KERN balance at the same time
· Many different transfer and recording
– Microsoft ® Excel/Access/Word in the
fore ground or background
– Other Windows applications (through key
simulation), e.g. shipping software or ERP
system (SAP, Sage, etc.)
– File recording (e.g. as text or CSV file)
– Print out on text or label printer
– Screen output such as large display, line
chart (drying curve for moisture analyzer),
histogram, etc.
· ODBC/SQL databases such as SQL Server
or MySQL
· Transfer to HTTP Webservices/Web forms
· Histogram
· Enables the connection of medical balances
to practice EDP systems using the device
data transfer protocol (GDT) and also the
HL7 protocol
· Implementation of programs/scrips using
freely-definable command lines
· Command sequences
· Defining the conditions for specific events
and the reaction to these events
· Filter for stability recognition (configurable
value storage)
· Central configuration repository, e.g. on the
· On-screen displays with configurable user
interface for flexible balance operation

If you do not need the features listed on the right, the standard version is the right choice. However, this version has also become a bit more expensive compared to the single version available so far.

Inexpensive alternatives

If you don’t need the extensive functionality of BalanceConnection and only want to connect a single scale to your PC, we offer two very inexpensive alternatives. Each of these programs has a single purpose and is therefore easy to set up and use:

  • 232key: Transfers the weight to any application (e.g. Excel, shipping software, etc.) using a key simulation (virtual keyboard wedge).
  • Simple Data Logger: Stores the weight in a CSV file (if desired with date and time), the weight can also be retrieved from the scale using a timer (Plus version only).

Record the weight from a scale or balance to a file – Simple Data Logger software

Connecting your scale to a PC and recording the weight should not be a difficult task. However, data logging software available from scale manufacturers or third parties is often expensive, difficult to use or frustratingly unreliable. We developed Simple Data Logger (SDL) to address these issues.

SDL writes the weight received from a scale or balance to a file, optionally adding the date and time. The CSV files generated by SDL can easily be opened in Excel and other spreadsheet applications for further processing and visualization.

Recording the weight from a precision balance using Simple Data Logger

SDL currently supports the following connections:

  • COM port: RS-232, USB virtual COM port, Bluetooth SPP, etc.
  • TCP/IP: Ethernet, WLAN (raw TCP format only).

Note: Your scale has to send data in ASCII format.

Get started recording weight values with Simple Data Logger

Connect your scale to your computer, download and install SDL, then follow these steps to configure the software (updated on December 7, 2019 – please refer to the documentation on the SDL website for the latest instructions):

  1. Input tab:
    Input tab: A&D scales and balancesIf your scale or balance is listed in SDL, simply select it and press the set default parameters for device button. Otherwise, select “generic measuring instrument” and enter the interface parameters manually. Set the radio button to match your connection: COM port (RS232, USB VCP, Bluetooth SPP) or TCP/IP.Make sure that you’ve specified a terminator (a.k.a. delimiter, the last character your scale sends in each line of data) or a timeout (e.g. 100ms, SDL will process received data if no additional data is received during this time).
  2. Output tab:
    Output tab (English US)Choose a file for the recorded data. SDL will create if for you if it does not exist (otherwise, data will be appended). Choose (or enter) a date and time format or select “None” from the list if you do not want SDL to add the date or time. Pick a decimal separator (for numeric values) and value separator (used to separate values from each other). The correct settings for your locale can be made automatically by clicking on the set values button.
  3. Start tab:
    Start tab: A&D FX-300i balancePress the start button to start recording data. Press the “PRINT” button on your scale or balance to send the weight to SDL. Depending on you scale, this button might have a different name (e.g. “DATA”). Some scales like the A&D FX-300i used in this example also have to ability to automatically transfer each (stable) weight. Data received will be shown in the event log (with the captured weight value shown in blue) and the weight will be written to the chosen file. Press stop to stop data logging and to close the file.

    Note: SDL can also handle continuous streams of weight data if this is what your application calls for (we’ve tested it with a scale which sends 100 values per second). The total number of recorded values is only limited by your disk space (but please keep in mind that Excel cannot open files containing more than 1,048,576 rows).

Process the weight values in Excel (or other spreadsheet applications)

Provided that you’ve made the right format settings in the output tab, you can easily open the CSV file in Excel (or other spreadsheet applications like Google Docs, OpenOffice/LibreOffice Calc). The weight will be recognized as a number, allowing you to make further calculations (i.e. calculating the total weight as shown below):
Everything shown here can be done with the “Basic” version of SDL (which is free for personal, non-commercial use). The “Plus” version has additional features including a timer to request the weight from the scale in user-defined intervals.

Very affordable licences can be purchased from our partner FastSpring (immediate license delivery).
