5 Manual (LOCAL) Operation
5.1 The Keypad / LCD Interface
Power On:
Position the rocker switch on the rear panel of the Matrix to the on position (Figure 2-2)
to turn on the matrix.
! Note:
The booting sequence will last about 15 seconds in which the LCD will appear
blank.
The figure above shows the LCD/Keypad (sometimes referred to as the “User
Interface”, or “UI”) at the top level of UI screens.
The “COMM” LED should normally be blinking green as an indication of normal program
execution.
The “REMOTE” LED, normally dark, will illuminate green when the matrix is in REMOTE
Mode (See Section Error! Reference source not found.).
The “ERROR” LED, normally green, will illuminate red upon the occurrence of an error
event, or the persistence of several error conditions (see Sections 5.2.2 and 6.5.1).
The LCD in the figure above shows the top level of the operational screen, which
happens to be a menu; the keypad is used to scroll through and select menu items.
Other screens encountered allow the operator to modify various parameter values; all
such “data fields” are presented with a currently set or default value blinking, prompting
the operator to modify the value. Some screens present multiple data fields, and the
keypad is used to navigate around them.
The keypad’s keys have multiple functions depending on which screen is being
presented.
The keypad’s round, center key is referred to as “ENTER” and serves as “set”, “select”,
“done”, or “return”.
The keypad’s arrow keys (pointing the 4 cardinal directions) are referred to as “UP”,
“DOWN”, “LEFT”, and “RIGHT”.
