Note*:
Set up and read the optical port frame as follows:
•
Baud rate, Number of Bit, Parity, Stop bit
The value of each parameters is as follows:
•
Baud rate: 300, 1200, 2400, 4800, 9600, 19200
•
Number of Bit: 7, 8
•
Parity: N (none), E (even), O (odd)
According to the above description, if we want to connect with the meter with baud rate: 4800
and number of bit: eight and parity: E with the last 1 bit, the command format will be as follows:
➢
AT+FMETER=4800,8,N,1<CR><LF>
Note:
For meters that comply with IEC 62056-21 standard, the command should be:
➢
AT+FMETER=300,7,E,1<CR><LF>
Upgrading Firmware
To upgrade the OP-730 firmware, the "QFlash_V4.0" program is used. After executing the EXE,
the window will opens as shown below:
