Display (LCD)
The iPump 6400's LCD indicates unit status and prompts for and reflects user input. The
LCD displays the
iPump 6400's unit label and serial number on the top line following startup.
The home screen also alternately displays the input signal’s frequency, data rate, and FEC
ratio in the lower left corner and continuously displays the current signal-to-noise ratio in the
lower right. Using the adjacent push buttons you can navigate the
iPump 6400's various
screens and edit data fields on the user-input screens.
Push Buttons These six push buttons are your means of commanding the iPump 6400 from the front
panel. The four arrow buttons allow navigation through the menu screens and parameter
selection and editing in user-input screens. The
ENTER button serves to select menu
options (downward navigation), to open user-input fields, or to commit user input to the
iPump 6400. Also press ENTER to quickly start the unit after a normal shutdown. The
Escape (ESC) button allows exit from user-input fields without saving the entry or selection.
ESC also provides upward navigation through the menu structure to the home screen.
