(4) Setting
Transmission speed, parity and stop bit should be set prior to transmission.
Set values before setting.
Transmission speed : 300 bps
Parity : None
Stop bit : 1 bit
[Note] After setting, the set data in memory are backed up by built-in battery.
(5) Communication control
q Method
Transmission of data with flow trasnmitter is made according to request command from host computer.
When a command is received from host computer, the data corresponding to the command is
transmitted from Portaflow to the host computer.
w Commands
Commands with ASCII code are transmitted from host computer to flow transmitter.
The last code of 1 command is carriage return (0DH).
