Front Panel Operation
After all connections have been made, power up the Matrix. The matrix will power on in Local
mode, so the front panel is enabled. After displaying the model number, and initializing itself, the
matrix will set itself to the connection paths that existed when it was powered down.
The following sections discuss general operations. Detailed operating sequences appear after the
general discussion
4.1
Remote and Local Modes
Manual operation is permitted whenever the matrix is in Local mode. The front panel can always
be used to view the state of the matrix. But to make changes, the matrix must be placed into
Local mode.
The remote computer can place the matrix in Remote mode, thereby disabling changes from the
front panel. However, the matrix can be returned to Local mode using its front panel menus. The
remote computer can also place the matrix into Local Lockout state. In Local Lockout state, the
front panel is disabled and cannot be used. The remote computer must release the matrix from
Local Lockout state before front panel control can occur. To allow recovery if the remote computer
fails, the matrix can be power cycled. It will always release the Local Lockout and revert to Local
state at power up. The matrix paths will be interrupted during this power cycle operation.
4.2
Setting Switches
To change the matrix connection in a fan in switch, first select the Input that is to be sent to a
different output, by pressing the IN key. To change the matrix connection in a fan out switch, first
select the Output that will have a new input assigned to it, by pressing the OUT key.
Pressing IN/OUT will change the LCD display to an edit mode. A blinking cursor will appear to
indicate the Matrix is waiting for data. Use the numeric keys to specify the desired port, or use the
UP and DOWN keys to increment/decrement through the available port numbers. When the
display shows the desired port, press ENTer to confirm the choice. Pressing ESC will cancel the
edit. At this point, no change has yet occurred to any connections.
Now press OUT for a fan in switch, or press IN for a fan out switch. The appropriate field will
change to edit mode, with the blinking cursor. The text message for this field includes the notation
SEL to indicate that this field is the one that actually makes RF changes. Changes made here are
going to affect the actual paths through the switches. Use the OFF key to break the RF
connection, or enter 0 as the selection. When the display shows the desired port, press ENTer to
confirm the choice. Pressing ESC will cancel the edit. The new RF connections are established at
this time.
As digits are entered, they scroll left, to the maximum number of digits allowed for the matrix. If an
incorrect digit is typed, follow it by correct digits, allowing the erroneous digit to “fall out” of the left
of the display area. Leading zeroes may be entered to flush erroneous digits. The ENT key
ac
cepts only the digits actually displayed. An entry of “0” is the same as pressing the OFF key
When the ENT key is pressed, the Matrix verifies that the number entered by the operator is
within the valid range of the matrix. If the operator enters a number that is out of range for the
matrix (e.g. typing in “9” for a 8x8 matrix), the operation is aborted, and the LCD displays the
previous selection. No change occurs in the RF path. If the number is accepted, the change is
made to the RF path, and the display is updated. Any leading zeroes are removed and the cursor
disappears
