MATRIX ROUTING SWITCHER
5 TOUCH KEYBOARD : LUMINOUS RE-LABELABLE
5.1 PRESENTATION
The keyboard permits the remote control of the switching matrix, without the use of a PC station.
It is housed in 19" 1‘U’cabinet, with 8, 16, 24 or 32 selection, or in a built-in box. The selected key is
illuminated. Each of the keys can be re-labelled, by writing in the name of the source or the destination.
This keyboard is auto - powered by the matrix, via the RS422 connector. Several keyboards can connect in
parallel on the RS422 line.
5.2 HOOK-UP
Connect the keyboard to the
switching 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 of
the keyboard. The set of the
keys blink when power is on.
5.3 EDITING PARAMETERS
Each key can get an individual function as Source
call, Destination call, or level audio +/-.
Parameters are given in the MatrixOp4 software
(see page 20
Control panel Programming
)
5.4 WORKING
First select an output (destination) using the keys of
the right part of the keyboard. The key illuminates,
as does the key that corresponds to the activated
input of the matrix. This operation does not activate
any switching, but allows you to show the status of
the matrix.
Choose an input (source) on the left part of the
keyboard. The key of the input illuminates if the
switching is OK.
The matrix also acknowledges receipt of the
switching by writing on the LCD display in the
front panel: « Comm/destination/source».
5.5 SCHEMATIC
This schematic is representative of the affectation of the keys. Each key can get a special function which can be
input or output, and video and/or RGB and/or audio.
The affectations are installed in the procedure « MENU EDITOR » of the MatrixOp4 software (see page 20
Control panel Programming
), and down loaded to the EEPROM memory of the switcher.
