      OHaus Weighing Scales: Set Up

      A detailed step-by-step guide for configuring your OHaus weighing scale

      Step 1: Connect to the Scale

      1. Power On the Scale:
        Ensure that the scale is turned on and ready for use

      2. Connect the Scale to a Computer:

        • Use a RS232 Serial Adapter Converter Cable with FTDI to connect the scale to your device

        • If your computer lacks a serial port, use an RS-232 to USB(-C) adapter

      Step 2: Access the Settings Menu

      1. Press the Menu key on the scale to access the settings menu

      2. Navigate using the Arrow keys to the Communication or Serial Port settings menu

      Step 3: Configure the Serial Port Settings

      1. Set the Baud Rate:

        • Navigate to Baud Rate and set it to 9600 bps

      2. Set the Parity:

        • Set to None

      3. Set the Data Bits:

        • Ensure it is set to 8 data bits

      4. Set the Stop Bits:

        • Set to 1

      5. Select the Flow Control:

        • Set to None

      Step 4: Configure Data Output Format

      1. Navigate to the Data Output or Print Format settings

      2. Enable Automatic Data Output:

        • Set to output automatically or via a specific trigger (e.g., pressing the print button or upon stabilisation of weight)

      3. Select the Output Content:

        • Configure the output to include:

          • Weight value

          • Unit (e.g., grams (g), kilograms (kg), pounds (lb))

        • Ensure no additional metadata (such as date/time or ID numbers) is included unless necessary

      4. Set Output Format:

        • Choose Single Line Output if available

        • Verify the output format string or layout (if customizable). It should output in a single line such as: 150.25 g

      Step 5: Save and Exit

      1. Save the configuration changes

      2. Exit the menu and return to the weighing mode

      Step 6: Verify Output

      1. Open a terminal or serial communication software on the scale app device

      2. Set the terminal to match the scale's configured serial settings:

        • Baud rate: 9600

        • Data bits: 8

        • Parity: None

        • Stop bits: 1

        • Flow control: None

      3. Place an object on the scale

      4. Observe the output in the terminal:

        • The output should display the weight and unit in a single line, e.g.: 250.50 g
