Chapter 4: Basic Analyzer Operation
To capture the data via the serial (RS-232) port, you will need a computer that is running a serial port
communications program, such as Hyperterminal. For information on setting up Hyperterminal to communicate
with the Analyzer, see “Using HyperTerminal” on page 179 in the Appendix.
The computer’s serial port should be set to the following:
Bits Per Second: 9600 (or a rate matching that set for the Analyzer)
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: Hardware
Interpreting Serial Output
If configured to output 500 RL format, the Analyzer outputs the data shown in Table 4 to the Serial (RS-232) Port
for every measurement,. On configurations without conductivity measurement, Field 7 is not available.
Note:
For long distance connections (up to 1,000 feet or 305 meters), GE Analytical
Instruments recommends use of either a RS-232 current loop converter or a RS-422
converter. You can also use an Ethernet connection.
