Configure your scale to work with your register device

Before connecting your scale, make sure it is in the correct configuration for your register device:

Connect the scale to your register device

You will need an RS232 serial cable plus a USB-to-serial adapter to connect the scale to your register device. Learn more. 

  1. Connect the USB end of the USB-to-serial adapter to your device.
  2. Connect the serial cable to the USB-to-serial adapter and turn the screws to secure the cable to the adapter.
  3. Connect the other end of the serial cable to the serial port on the back of the scale and turn the screws to secure the cable to the scale.
  4. Connect the power cable to the scale, then connect the other end to a power outlet.

Connect and configure the scale in the Dutchie Register settings

  1. Use an RS232 serial cable and USB-to-serial adapter to connect your A&D scale to your register device. You can use a USB hub or adapter if you need additional USB ports or your device has USB-C ports.
  2. Sign in to the Dutchie Register and select Settings from the left navigation menu.

    If you're using an A&D Scale and WebSerial-compatible browser, select Add new scale and follow the on-screen instructions to connect and authorize your scale.

  5. Once authorized, you can select A&D Scale from the dropdown.
  6. Place an item on the scale and press the PRINT button on the scale. Confirm that the weight reading from the scale appears in the Test weight reading field on the register.

    The Dutchie Register web application is configured by default to work with the factory settings for A&D scales: 2400 bps, 7 bits, even parity.

    The Dutchie Register Terminal requires 9600 bps, 8 bits, non-parity.

  7. If you’re using a Dutchie Register Terminal or a different scale configuration, click Advanced Settings to select the settings that match your scale’s settings. If you have an A&D FX-series scale not connected via 232Key, you can click Auto-configure scale to detect your scale’s current settings and configure the Register settings match.

  8. Click Save settings and then Return to settings.

Optional and recommended Backoffice settings

Restrict to scale weighing

The Restrict to scale weighing setting is recommended because it prevents users from altering or entering a weight other than the scale reading. Note that this setting is register-specific and does not interfere with the weight override (or "weigh heavy") function.

  1. In the Dutchie Backoffice, go to Settings > Devices > Registers. 
  2. Select a register. 
  3. Scroll down to Restrict to scale weighing and select Yes.

  4. Click Save.

Weight override ("weigh heavy")

Weight override is an optional feature that allows users to price bulk flower based on common weights (1g, 2g, 3.5g, etc.) even when the actual weight is slightly different (also known as "weigh heavy"). If weight override is not enabled, bulk flower is priced based on the actual weight. Contact Dutchie Support to have weight override enabled for your location.

When weight override is enabled, it's important to also set a Dispense weight vs actual weight threshold. This enforces a maximum difference between the actual weight and the weight override to prevent users from weighing excessive amounts or charging an artificially low price.

  1. Go to Settings > Location.
  2. Scroll down to the Defaults section.
  3. In the Dispense weight vs actual weight threshold field, enter an amount greater than 0 and select a unit of measure.

  4. Optionally, turn on Auto Adjust Weight Override. When enabled, if the weight of the product falls within the dispense weight vs. actual weight threshold, the item's price will be automatically adjusted accordingly.
  5. Click Save.

This threshold is not inclusive. For example, if you set the threshold to 0.2g, budtenders can enter an override that is less than 0.2g different from the actual weight, but not 0.2g or more.
