5.5 RS-232 Interface
The RS-232 communications protocol allows the instrument to be connected to a wide variety of
computer based equipment. The interface provides two basic functions in the M200A.
1. First is a comprehensive command interface for operating and diagnosing the analyzer in
interactive fashion. This mode is for use by a human operator issuing commands to the
instrument.
2. Second is the equivalent command interface described above, but with the interface set
up to be operated by a computer program rather than interactive commands.
3. The interface can also provide an audit trail of analyzer events. In this function the port
sends out messages about instrument events like calibration or warning messages. If these
messages are captured on a printer or remote computer, they provide a continuous audit trail
of the analyzers operation and status.
