Manual (LOCAL) Operation
UP and DOWN serve as “scroll up”, “scroll down”, “increment”, or “decrement”. Many
data fields’ values are modified by UP and DOWN, and many of those allow the
pressing and holding of the UP and DOWN keys to cause an acceleration of the
incrementing or decrementing.
The keypad’s upper left diagonal key is referred to as UP DIAG. This key serves as
“back”, “clear”, or “escape”.
The keypad’s lower left diagonal key causes no action in the context of any screen.
LEFT and RIGHT serve as “next” and “previous”; these keys are used almost
exclusively to navigate around the user data entry fields many screens present.
Caveats:
The UI device may demonstrate a “speed limit” when it comes to how rapidly the
Operator may actuate keys and still get the correct response on the LCD: the Operator
is encouraged to find a comfortable cadence when operating the keypad.
! Note:
To preserve the life of the LCD, it has a ‘screen saver’ feature. After 5 minutes the LCD
backlight will turn off. Once dark, pressing any key will have no effect other than to re-
illuminate the backlight.
The matrix will power up in LOCAL Operating Mode. LOCAL Operating Mode means
that the matrix is receiving commands from the front panel (Keypad).
When in LOCAL Operation Mode the matrix will switch automatically in REMOTE mode
as soon as commands coming from a remote control computer are received (Ethernet,
Serial or USB). The matrix will return to LOCAL Mode upon the pressing of any key.
The matrix will not accept any other local commands until the operator switches to
LOCAL mode by pushing any button on the keypad.
As stated before, to switch to REMOTE Operation Mode the operator needs to send a
command (Ethernet, Serial or USB) by means of a remote control computer.
All LOCAL operation of the matrix is accomplished via the front panel’s Keypad / LCD.
The various screens encountered in the matrix’s operation contain the following
controls:
