MATRIX ROUTING SWITCHER

6 INCREMENTAL TOUCH KEYBOARD AND LCD DISPLAY

6.1 PRESENTATION

This keyboard permits the remote control of the
switching matrix, without the use of a PC station.
It is housed in a 19 inch 1U cabinet, with 2 keys for
selection of the inputs, 2 keys of selection for the
outputs, and a validation key. The configuration
status of the switch actions selected is shown on the
LCD display.
This keyboard is powered from the matrix, via the
RS422 connector.
Several keyboards can connect in parallel on the
RS422 line, and are interactive.

6.2 HOOKUP

Connect the keyboard to the MATRIX by a
straight flat cable and complete with Male/Female
Sub-D 9 connector, in the RS422/keyboard
connector of the matrix, and the RS422/matrix
connector to the keyboard.

6.3 EDITING PARAMETERS

Parameters are given in the MatrixOp software (see
page 18 EDITING THE MENUS)

6.4 WORKING

First select an output (destination) using the two
keys destination + and -. The LCD display indicates
the selected destination ( output n), and also the
state of the corresponding active input. This
operation does not make a switch action, but does
permit the display of the state of switching of the
matrix.
Then choose an input (source) using the two keys
source + and -. The LCD diplay indicates the
selected source (input n). As before, this operation
does not invoke a switch action.
Validate then using the ‘validation’ key . The
keyboard then sends the switch command to the
matrix.
The diplay confirms the action by one asterisk *.
The matrix also acknowledges receipt of the switch
action by writing on the LCD display on the front
panel: «Comm/destination/source».
In case of receipt: «Err. /destination/source», the
communication from keyboard to matrix has not
been made correctly.
Check the RS422 cable. Also check the capacity of
the matrix in relation to the demand of the
keyboard.
