Front-Panel Operations
Front-Panel Menus and Screens
If no SER events are available, the message shown in Figure 4.21 is displayed.
While viewing the SER events, front-panel pushbuttons provide navigation and
control functions as indicated in Table 4 .6.
Hold down either the Up Arrow or Down Arrow to achieve accelerated scrolling.
Holding down the Up Arrow or Down Arrow navigates one screen at a time for the
first five screens, and then increases to five screens at a time if the button remains
pressed. Accelerated scrolling stops at the newest or oldest SER event record
available, depending on the direction of the scrolling.
When the upper limit of the SER events is reached, press the Down Arrow one
more time and the report will wrap around to display the screen containing the
first SER event. Similarly, when the lower limit of the SER events is reached,
press the Up Arrow one more time and the report will wrap around to display the
screen containing the last SER event.
By default, three SER events are shown per screen. You can change this to five
per screen by setting SER_PP to Y. This will cause the element name and state
information to be shown on the same line, with the element name truncated to ten
characters and the state truncated to eight characters.
