Using the LI-8150 Multiplexer
Cable Connections
LI-8100A
There is a panel for connecting the communications, chamber, and Auxiliary
Sensor Interface cables on the left side of the LI-8100A Analyzer Control Unit.
These connectors have slightly different uses when the LI-8150 Multiplexer is
connected to the Analyzer Control Unit. The LI-8100A side panel appears as
shown in Figure 10-4 below.

Figure 10-4. LI-8100A Analyzer Control Unit cable connection panel.
There are two hose/cable bundles included with the LI-8150; the yellow cable with
large bulkhead connectors on either end connects to the port labeled Aux. Sensor
Interface on the LI-8100A, and to the port labeled LI-8100A on the LI-8150. The
second hose bundle has three air hoses and an electronic cable. These hoses are
connected to the side panel of the Analyzer Control Unit, as shown below. The
hose for Air In has a male fitting and the hose for Air Out has a female fitting. Note
that one of the hoses has a piece of black shrink wrap; this hose attaches to the Air
In fitting on the Analyzer Control Unit. The bellows hose has a male fitting, and
attaches to the port marked Bellows on the Analyzer Control Unit. Insert the hoses
until the fittings snap into place. To remove the hoses, slide the collar on the
fittings; the collar on the bellows and Air In fittings slide toward the Analyzer
Control Unit, and the collar on the Air Out fitting slides away from the Analyzer
Control Unit.
