●
An RS-232C connector (D sub 9 pin male) is attached to the side of the display box.
●
When connecting the display box with a personal computer, etc., please use an RS-232C cross cable.
When receiving 4 bytes of data as indicated in 1-1 while using the scale in weighing mode, weight data will be output in 14 bytes, as indicated in 1-2.
* While the scale is used with lb (pound) measurement units, the weight data will be output in lbs (pounds).
While the scale is used in BMI mode, the output data will vary depending on the form of the received data.
When receiving 4 bytes of data, as indicated in 1-1, the scale will calculate your BMI using the currently input height figure, and 26 bytes
of data will be output, as indicated in 2-1 or 2-2, depending on the measurement unit.
When receiving 11 bytes of data, including measurement units and height figures, in the form indicated in 1-2 or 1-3, the scale will calcu-
late your BMI using these figures, and 26 bytes of data will be output, as indicated in 2-1 or 2-2, depending on the measurement unit.
