Installing the GC 1
Agilent 7890B Installation 45
Step 11. Connect the external cables
Most installations involve plugging a cable from the LAN into
the GC’s LAN cable port. Additional cables may be installed for
control of the GC’s automatic liquid sampler (ALS), connecting
signal output to integrators, synchronizing the start and end of
a run between various instruments, sensing conditions external
to the GC, and controlling devices external to the GC.
If using Event or BCD cables, label the cables as needed to
identify their intended use and appropriate connector on the
GC. See Labeling BCD and EVENT cables.
Back panel connectors
The figure below shows the connectors on the back panel of the
GC.
See also “Cable Diagrams” on page 86.
Sampler connectors
If using an ALS, connect it to the GC using the following
connectors:
SAMPLER 1 Optional. An injector, usually the front injector.
(For 7693A/7650, the GC automatically senses the injector
location. For a 7683 injector, typically configure this injector as
INJ1.)
