Output Data Format

Explanation for RS-232C-compliant output

This explanation is for the interface to output the readings from the GB Digital Baby-Scale BD-815U to external equipment (e.g. PC) as a RS-

232C-compliant signal.

Grams (g) mode (transmission data)

Transmission data is output immediately after measurement regard- less of the status of the reception side (e.g. PC). Therefore, the recep- GB tion side must always be ready to receive data before any measure- ments are taken.
