5.6 Status Output

The status output is an option that reports Analyzer conditions via contact closures on the rear
panel. The closures are available on a 50 pin connector on the rear panel. The contacts are NPN
transistors which can pass 50 ma of direct current. The pin assignments are listed in Table 5-8
below.

5.7 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 M9110AH.
1. First is a comprehensive command interface for operating and diagnosing the analyzer. The
command set can be used interactively or operated via stored program. This interface has,
in fact, more capabilities than the front panel keyboard.
2. The interface can 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.
