pH/Water Quality Meter F-7X BW
Low-spec Command Reference
Preface
This manual describes the communication command list of the pH/Water Quality Meters with serial
communication function, LAQUA-PH1100/PH1200/PH1300/PC1100/EC1100.
The contents of this manual are subject to change without notice.
Caution
Use the optional USB cable (part number: 3200373941) or serial cable (part number:
3014030151) to connect the instrument to a personal computer (referred to as PC in the rest
of this document).
Make sure that the transfer format used in the instrument and a PC are the same.
When different transfer format is used, a communication error occurs and the online mode
does not start up, and as a result RS-232C communication cannot be performed. Also, when
the transfer format is changed, turn OFF the power of the instrument and PC and then reboot
them.
The transfer format of the instrument is as follows.
 ・Baud rate: 2400 bps
 ・Character length: 8 bits
 ・Parity: None
 ・Stop bit: 1 bit
If you write the program for serial communication, at first, write the command to change the
instrument to the online mode. By changing the instrument to the online mode, its operation
keys except for key are locked and it changes to serial communication mode.
If the instrument’s power is turned OFF, reset the online mode.
If the instrument does not receive the command or occurs any errors after it requested the
data, add the waiting time of a few seconds before request the data again.
If the instrument received the data continuously, the instrument does not response.
The instrument cannot be controlled by using the DCD, CTS, and DSR.
It is necessary to switch RTS to ON to perform communication. Set it 2.4 V above.
Pin assignment of the instrument and the external instrument are follows.
Instrument side (A connector MINI DIN 8 PIN)
2 TX
3 RX
4 CTS
5 COM
External instrument side (B connector DSUB 9 PIN)
2 TX (RX at an external instrument side)
3 RX (TX at an external instrument side)
5 COM
7 CTS (RTS at an external instrument side)
