This document provides an overview of a VB.Net project that processes serial data from a scale and passes it to a midrange system. It reads serial data from the scale, parses it depending on the scale number, arranges it for processing by the midrange system, creates a flat file in a predetermined directory for automated processing, logs each weight transaction and related data, and logs all errors for troubleshooting. The configuration file contains variables for the serial port settings, file paths, and midrange system parameters. It parses the serial data based on scale before creating a properly formatted data file to send to the midrange system for processing.

3. Serial Scale to Midrange Interface
The purpose of this document is to provide an overview for a previous project.
The purpose of this project was to process serial data taken from a serial scale an pass it to a midrange system from
processing:
• Read serial data from the scale
• Parse the data depending on scale #
• Arrange the data in a way for processing by the midrange system
• Create a flat file in a predetermined directory on the midrange system for automated processing
• Log each weight and its related weight data
• Log all errors for troubleshooting

4. Configuration File

5. All of the variables needed for the serial port, file paths, rooms info, and
midrange parameters are located in this file so there is no need to
change code in the event of a system change.

6. Serial Configuration

7. All the settings for the serial port are pulled from the configuration file before opening the port.

8. Serial Data Parsing/Data File Creation

10. Above shows parsing of the serial data based on scale before creating the file needed for processing on the
midrange system. After everything is parsed and ready , we create a new file at the predetermined path with
the properly formatted data.

11. Transaction Logging/Error Collection

12. Above is a simple error log that is used to in all subroutines for
troubleshooting. Also we write to a simple process log for capturing all
the weight information sent over to the midrange system in case we
need to look back at what weights were send and when.
