LI-820 Software and Data Output

Multiple Data Outputs

The LI-820 comes with a Windows® interface software for instrument configuration, control, data collection, and display. Your choice of parameters (CO₂, cell pressure, or cell temperature) can be output via fully calibrated voltage or current outputs. In addition, 0-5V alarm relay outputs can be connected to audible alarms, relay switches, automatic dialers, pumps, or valves in industrial settings. The LI-820 is connected to the computer via an RS-232 DB9 serial cable connection.

For complete integration of the LI-820 into other equipment controls for OEM applications, the instrument also features a communication protocol based on a subset of the eXtensible Markup Language (XML). XML is a simple text-based language that allows you to communicate with the LI-820 using simple text strings sent bi-directionally between your computer and the instrument over the RS-232 port. Using XML, the LI-820 can be polled for data at user-defined intervals, globally reconfigured, or configured to perform automatic calibration routines, for example.
