Getting Started: Create Items and Connect your Scale
Create Items
The first thing is to set up your items by weight. Scales will not calculate for any unit type — only weight-based units.
- Sign in to your online Square Dashboard.
- Navigate to Items > Units.
- Click Add Unit.
- Next, in order to sell an item by weight, make sure to choose a weight measure. You can choose one of the following units: Gram (g), Pound (lbs), or Ounce (oz).
- Once you set up the weight unit and precision, head to your Item Library > click Create an Item. Enter the item name, category, details, and make sure to select a unit type for weight.
- Once you’re all set, click Save.
Connect Your Scale
To connect your scale correctly, you must use the latest version of the Square app on your iPad (version 5.30). Also, please ensure that you have correctly set up items to sell by weight and have connected the scale to your device by following the steps below.
To connect a USB scale to your Square Stand:
- For iPads with Square Stand, you will need the serial-to-HID adapter sold separately on Square Shop.
- Plug in the 9 pin male end of the serial-to-HID adapter into the port on your scale. To keep the adapter firmly connected, twist the security screws into place.
- Plug the Micro-USB end of the cable into the adapter, and plug the USB-A side of the cable into your scale.
- To check the connection, open the Square Point of Sale app and tap the three horizontal lines on the navigation bar.
- Tap Settings > Scales.
- The connected scale should appear in the app menu as USB Scale.
To disconnect the scale, simply disconnect the cable. Keep in mind, you can only pair one USB scale with your Square Stand at a time.
To connect the Brecknell 6700U scale or CAS SW-RS scale to your Square Terminal or Android device:
- Plug the 9-pin male end of the RS-232 cable into the port on your scale, and insert the USB-A male side into the hub for your Android device.
