1.6.4 RS-232

The RS-232 connection is a male, 9-pin D-sub connector at the location shown in Figure 1-3.
See also Appendix A for additional information.

1.6.5 Pneumatic System

The Model 300M is equipped with a vacuum pump capable of pulling 800 cc/min across a flow
restrictor. This allows a smooth, stable flow of sample through the analyzer.
Sample enters the analyzer through a particulate filter element (47 mm diameter) mounted
immediately behind the front panel. The sample then enters directly into the sample cell. Please
see Figure 1-1 for a flow diagram and Figure 1-4 for pneumatic connections.
