The body analysis scale BC-1000 has a wireless interface to send actual user data to the scale and receive the measured data. Therefore you need an „USB ANT+ Stick" and the according USB driver. You will find the driver on the GMON installation CD in the directory „usb_driver" or in the Internet: www.thisisant.com/products/data-sheets-brochures (ANT USB Driver - Windows). You can also install the Garmin Agent from here: www8.garmin.com/fitness/ant_product_page.jsp. The Garmin Agent installs the USB driver, but it does not support the BC-1000 scale directly. It only support it in connection with the Garmin watches FR60, FR61 and Forerunner 310.
The Connection to the scale starts with an dialogue:

Please choose body type and activity according to the instructions in the manual of the scale. With the button [Start Measure] the „USB ANT+ Stick" will be detected and a radio connection to the scale will be realised. The scale will answer with an acoustic signal. Now enter the platform. After an successful measure the dialogue will be closed and the measured data will be displayed in the input mask. Here you can [Save]. The data will be send to the GMON database and are available for further analysis.
