4.2.1 ST Command
When this command is sent to the BM-7AC, measurement starts. After measurement is finished,
the measurement data is sent from the BM-7AC.
Transmission from the PC to the BM-7AC
After the USB or RS-232C line has been made active, the PC transmits the character string
"ST" (ASCII code 53H 54H), and then the PC transmits Cr (0Dh), Lf (0Ah).
Check of reception in the BM-7AC
After the BM-7AC receives "ST" + (Cr･Lf), it returns “OK” + (Cr･Lf) as a check command and
starts measurement.
Communication of measurement data
After measurement, the BM-7AC transmits the measurement conditions and measurement data.
The delimiter (Cr･Lf) is attached to the end of 1 data string and the data are sent. After all the
data is transmitted, the ending code "END" is transmitted.
