Connecting and Configuring Data Output
The LI-820 communicates through a serial port on the front of the instrument. This port is
configured as follows:
Baud Rate: 9600 bps
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
After a serial connection is established, the LI-820 will immediately send data out the serial
port in the manner in which it was configured previously. In order to reconfigure the LI-820
to output specific data values, you must send the RS-232 portion of the XML grammar to the
instrument with the desired values "turned on". To "turn on" the data value, set the value of
the element to TRUE. As an example, the following string is sent to the instrument after a
connection has been made between the computer (using the Windows® application software)
and the LI-820:
<LI820>
<CFG>
<OUTRATE>1</OUTRATE>
</CFG>
<RS232>
<STRIP>FALSE</STRIP>
<ECHO>FALSE</ECHO>
