4.5 Program Operation
4.5.1
Swatch Global Preferences and Port Properties.
The power meter settings, calibration enabling, and return delay values for the Redundant
Amplifier are controlled through two mechanisms:
Global
Preferences
establish system wide settings. Some global preferences are used
to force all ports to use global values for certain functions. Global preferences also
provide the values for those ports that individually are configured to use global
preferences even when they have the option to be locally configured.
The
Unit Properties
determine the settings for the port(s) of a unit when not
overridden by global enable preferences. These are controlled in the Unit Pane via
either a Properties display or a Status display. The unit and port properties are saved
in the Site Map file, even when not enabled for use.
4.5.2
Scanning and Communication Errors
The S
WATCH
TM
program scans the system at an interval established in the
Preferences
dialog.
During the scanning process the program ensures that each unit is connected to its respective COM
port. If up to ten communication errors are encountered, a yellow icon will appear in the
Site
Map/Unit List
. If, after ten system scans, a unit does not “respond” it is determined to be off-line
and will appear in red in the
Site Map/Unit List
. An entry will also be added to the
Event Log
.
4.5.3
Site Map/Unit List
The
Site Map
and
Unit List
are a graphical representation of the units in the system.
The
Site Map
displays units in a tree format whereby individual units or ports are sub-units of
larger “branches” or nodes. (See
