Connecting software and downloads should always be addressed by the IT department for safety reasons and can vary depending on what type of computer platform is being used.

Consult the IT department if driver protections are preventing the use of the USB driver. Driver protections may need Note to be temporarily disabled on Windows 10 or later computers to allow for the installation of the USB driver.

1. Connect the scale's indicator to a PC using a USB-Type B to USB-Type A cable (not included).

2. Turn the indicator on.

Note

In most cases, the PC should find the driver and automatically configure the driver when the scale is plugged into a USB port.

3. Open a terminal emulation program, such as Advanced Serial Port Terminal, pUtty or Hercules (used in this example).

4. Connect to the serial port assigned by the PC (COM5 in example). This can be found in Device Manager. Once selected, press Open.
