Real-Time RS-232 Output
During the RUN mode, the personalDataRAM can communicate real-time
concentration data through its serial port via the pDR-COM software package. This
software application decodes the data and displays it on the computer screen in both
graphical and tabulated form.
In order to use this output with some other application, the following information
will enable the user to decipher the encoded output signal.
The communication settings for the digital output of the personalDataRAM are:
•
Baud rate:
•
Data bits:
•
Stop bits:
•
Parity:
•
Flow control: Xon/Xoff
