4. RS-232C Communication Specifications

■ Specifications

Communication standard EIA RS-232C
Communication method Asynchronous method
Signal speed 2,400 baud
Data bit length 7 bit
Parity EVEN
Stop bit 1 bit
• An RS-232C connector (D sub 9 pin female) is attached to the side of the display box.
• When connecting the display box with a personal computer, etc., please use an RS-232C straight cable.
• Use the RS232C cable ahorter than 3m long.

■ Weighing Mode

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.

■ BMI Mode

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
calculate 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.

5.Troubleshooting

Solution
•When Using with the AC Adapter
Ensure that the AC Adapter cable is properly connected with the Display Unit. Ensure
that the AC Adapter is correctly inserted in the mains DC jack.
•Using dry cell batteries
The batteries may have run out. Confirm that the equipment is working by using the
AC Adapter or new batteries.
•Please confirm that all the adjustable feet are resting on a level surface.
•Measurement may be impossible in the case of excessive vibration. Use the equipment
in another place.
•It is possible that the maximum weight capacity has been exceeded. Please stop
measuring.
•Do not stand on or put objects on the Platform before starting measurement. Start
measurement after confirming there is nothing on the Platform.
