When you set the No Analyzer switch ON, the front panel will communicate only with other GC's; the
front panel will not communicate with an attached analyzer.
When the Lock Out Remote switch is ON, another front panel on the network cannot access this front
panel, but this front panel can access other network front panels.

Remote Operation

To understand remote mode operation, visualize the LO COMM PCB as directing analyzer data traffic
along three different routes.
When the operator at this display/keyboard communicates only with this analyzer, data runs back
and forth between the display/keyboard and the analyzer. This represents the standard, or stand-
alone, mode of operating the analyzer.
When the operator at this display/keyboard communicates with a remote GCC, data runs back
and forth between this display/keyboard and the remote GCC.
When the operator at a remote display/keyboard communicates with this analyzer, data runs back
and forth between the remote GCC and this analyzer.
Since the remote mode functions simply by establishing communication routes, operating an analyzer
from a remote location is virtually identical to local operation once you establish the communication
link. The only differences are a remote front panel status message and the method by which recorder
outputs are handled.
To establish remote communication, perform the following steps:
1. From any screen menu, press and release the following keys in sequence: "Upper," "Enter," "R".
2. The Remote Front Panel Mode menu appears on the screen (see Figure 4-59). This mode starts
automatically if you turn power ON with No Analyzer switch ON.
