5.3 USB Connection

The scale has the capability of connecting to a Windows

computer (PC) using a USB cable (not included) and a terminal

emulation program. A terminal emulation program allows the transfer of data between the scale and PC using a serial port.

Figure 5-3. Connection Ports

Apple

and Macintosh

computers are unable to transfer the necessary data to the scale. Only use a PC for data transfer.

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

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.

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

5. With weight on the scale, press and hold the

Print

button on the indicator for three seconds. The patient’s weight is

sent to the PC.
