MATRIX ROUTING SWITCHER
1 HARDWARE
1.1 GENERALITIES
The Kramer matrix switchers are used to select and
dispatch electric signals, as audio, video and RGB,
to several destination simultaneously. The
impedances of each machine which is connected on
the matrix are well respected, even if a signal goes
to two outputs and more. As a matter of fact, a
signal under 75 Ohms can’t be delivered on several
loads without any amplification dispositive.
In fact, each output is able to select one, and only
one, input. We can consider the matrix routing
switcher as an assembly of several selectors which
are adjacent and connected on common inputs.
Each selector is fully independent, and individually
controlled. When two selectors, or more, request
the same source, this last is then distributed. So, it
have to be buffered to avoid losses of electric level
and reduce of bandwidth. The number of selectors
depends of the power and the quality of the buffers.
The control of the switching and the others
commands is provided by an interface RS232/422,
via an internal bus.
The routing switcher don’t make use of a keyboard
in front panel. The access of this keyboard should
not be easy, or impossible, when the matrix is at the
heart of the audio and video lines, to have the
shortest length.
A supervisor, a computer or a remote control panel
must necessarily control the matrix by the RS232
and RS422 connectors.
Several LED lights on the front panel shows the
receipt of the RS232/422 datas, the kind and the
result of the actions.
An electric power supply provides four various
tensions the cards of the machine.
1.2 RACK DISPOSITION
The cards are housed in a 19 inches rack, with 360
mm depth, and a height which is multiple of 3RU,
according to the number and the dimensions of
each section.
Many section, as audio, video, RGB, YC, or YUV,
can be inserted in the same rack.
The cards are introduced by the rear panel and
support the audio and video plugs.
These are BNC for composite video, components,
YC and RGB. For the audio, (balanced or
unbalanced), the plugs are terminal blocks 6 points
detachable.

1.3 CREATING A MATRIX
The rear panel of the rack is 19” wide, on 3RU
high. The mains, RS232 and RS422 plugs 1RU,
and the useful area for the audio, video et RGB is
also 1RU. The BNC or audio connectors are shared
by 32, on horizontal bands which are 1RU wide.
We can house up to 3 bands in a 3RU area, i.e. 96
BNC or audio plugs. So, we can realize a 32x64
video matrix, or a 64x32…
When more, the rack has to be 6RU high. Then the
total number of plugs rise to 192, and permits
important dimensions. With a 9 RU rack, the
number is 288, etc.
The stereo audio plugs are also shared by 32, on
1RU band. We can house 3 bands, i.e. 96 stereo
audio plugs. For example, in a 3RU unit, we can
realize a stereo balanced 32x64 or 64x32, more in a
6RU, etc.
In YC mode, the capacity the divided by two ; in
component mode, by three ; in RGBHV mode, by
five.
1.5 RGBHV SECTION
RGBhv architecture is the same as the video
section :
Each card can support the R, G, B, H or V, and is
simultaneously controlled.
The input and output impedances is a 75 Ohms on
BNC, and the bandwidth is 350 MHz minimum.
1.6 AUDIO SECTION
The architecture of the audio path is different.
1.4 VIDEO SECTION
The video section in an area with cards including
the input and outputs plugs, the buffers, the
switchers, the outputs 75 Ohms amplifiers, and the
controllers. The input cards (called QMI), and the
output cards (called QMO), own four edge
connectors to get the power supply and the service
signals by the internal rail.
Each cards has 32 BNC connectors for in or out.
There is no module as for the video, but traditional
cards, directly connected on the internal bus. On
this bus transit the stereo audio signals, and also the
power distribution and the service signals.

KRAMER
Electronics
MATRIX ROUTING SWITCHER
The cards are horizontally located, and can be
extracted by the front panel. Each card own up to
32 stereo plugs. There is two types of audio cards :
- Input audio cards.
Called WMI, these cards are identical between
themselves. The only differences are the serigraphy
of the panel and its position in the slots.
When viewing from the rear panel, these cards are
immediately slotted near the QMOSD card
(communication card). Their 32 audio plugs can be
set up in factory, as balanced or unbalanced, or
mixed.
Balanced mode has a +4dB level under 6 KOhms
impedance., and the unbalanced mode, -6dB under
10 KOhms. Dynamic is 12 dB. The inputs are
directly introduced into the integrated circuits, and
have no galvanic isolation.
- Output audio cards.
Called WMO, these cards are physically identical
between themselves, but have to be programmed
for identification. Their position is immediately
near the input cards. Their 32 audio plugs have no
galvanic isolation. The output impedance is 50
Ohms. We can use the output in balanced mode, as
in unbalanced only without connecting the inverted
pin. (Do not connect this pin to the ground).
Up to 32 VCA (Voltage Control Amplifiers) can be
wired in factory. So the audio level can be adjusted
with a special RS 232 command.
1.7 OTHERS SECTIONS
YC (S-video), component YUV, and RGsB can be
realized with the analogue video cards, with the
same principle as RGBhv section.
1.8 COMMUNICATION
The card called QMOSD is the heart of the
KRAMER matrix routing switcher. This card own
a clock generator, a microcontroller, and provides
the service signal to the others cards of the
machine. The reception and the treatment of the
RS232, RS422 and Ethernet is made inside and the
datas are then transferred the concerned switchers.
As there is no keyboard on the front panel of the
matrix, the QMOSD card take on the dialog with
the external keyboard by the RS422 link.
1.9 ON SCREEN DISPLAY
The GMOSD card has a SVGA 800x600 generator
that is available on a SubD-HD15 connector. An
external screen can be connected on, and propose a
listing of the matrix status.
On the left is shown the list of 80 input sources, as
13 characters names.
On the right area are shown 80 outputs name, with
the status of switch.
A mouse can be connected on a USB-A connector,
to control the upper tool bar, and to create switches.
The loading of this table is automatically done with
the MatrixOp4 software, after entering the
assignment operation.
1.10 INTERVAL SWITCHING
Switching during the black interval is basic to get a
clean change of picture, without break of the
synchronization, and cut in the middle of the
screens. When the reference signal is present
(blackburst), the switching takes place in the
beginning of the video frame, that is to say in the
middle of the line N°2 or 314 in PAL/SECAM
(N°2 or 264 in NTSC). The maximum waiting time
is of 20 mS in PAL and 16,7 mS in NTSC. This
operation can be effective only when the sources
are synchronized with the blackburst. If this
condition is not perform, then the switch is made
normally out of the interval time.

MATRIX ROUTING SWITCHER
NOTES on the above table:
NOTE 1 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform
the instruction; and if the instruction is performed (due to a keystroke operation on the front panel),
then these codes are sent. For example, if the HEX code
01h 85h 88h 83h
was sent from the PC, then the switcher (Layer 3 = YUV) will switch input 5 to output 8. If the user
switched input 1 to output 7 via the front panel keypad, then the switcher will send:
41h 81h 87h 83h
to the PC.
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid,
the switcher replies by sending to the PC the same four bytes that it was sent (except for the first byte,
where the DESTINATION bit is set high).
NOTE 2 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes
as were sent are returned, and the OUTPUT is assigned the value of the requested parameter. The
replies to instructions 10 and 11 are as per the definitions in instructions 7 and 8 respectively. For
example, if the present status of machine layer 5 (RGBhv) is breakaway setting, then the reply to the
HEX code
0Bh 80h 80h 85h
would be
4Bh 80h 81h 85h
NOTE 3 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or
if a parameter associated with the instruction is out of range (e.g. trying to switch a 16x16 matrix with
an input or output greater than 16, or trying to switch an input or output greater than the highest one
defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is
being programmed via the front panel. Reception of this code by the switcher is not valid.
NOTE 4 – The output VCAs are 32 logarithmic steps. Values are 0 to 31 (decimal).
NOTE 5 – The input levels are 32 logarithmic steps. Values are 0 to 31 (decimal) and coded in the 5
lowest bits of the output byte.
When bit 5 = 0, the gain value is taken.

MATRIX ROUTING SWITCHER
7 MatrixOp4 SOFTWARE
7.1 INTRODUCTION
The principle of the routing switcher is to connect
each of its outputs to any or all of the inputs.
Therefore the possible points of switching is a
multiple of the number of inputs and the number of
outputs.
This principle is best described in the listview form.
This grid is composed of switching points, and of
distributors. (For instance Input 1 can be switched
to Outputs 6,7 and 8…)
The management of these switching points can be
activated by using a touch keyboard, but this
solution can quickly become complex as the matrix
becomes larger. Thus the use of a computer to
manage the system is preferable.
The MatrixOp4 software does not physically
represent the routing switcher, but rather the
environment in which the various devices exist.
Therefore you will have to display these devices in
a diagram, without taking into account their state of
readiness, or receiver, video or audio (mono or
stereo), nor of their hook-up to the grid.
A simple control allows you know quickly the
actual setup of the matrix.
7.2 Glossary :
Assignment
An audiovisual device which is connected on the
switcher may be assigned : MatrixOp4 has to know
its parameters : names and numbers of the
connectors.
Destination
Object connected on an output of the switcher.
On Line / Off Line
When the router is « OFF LINE », all information
is received and stored, but not executed. Recall and
execution are made when « ON LINE ».
Object
The devices connected on the matrix routing
switcher are called in this documentation
« objects », and have to be parametered with the
assignment editor (see page 19 assignments editor).
this edition have to be realized only in the first
installation or when changing some equipment.
Page or Sheet
The status of the router, the VCA levels, and the
general information about the connections, are
called « page », are saved in files with extension
« .cnx ».
Layer
A matrix routing switcher can contain many
different layers, according to the kind of electric
signals :
Composite Video layer
Analog Audio (mono or stereo) layer
S-Video (or YC) layer
YUV layer
RGB or RGBS or RGBHV layer
AES-EBU (Digital Audio) layer
SDI (Digital Video) layer

MATRIX ROUTING SWITCHER
Source
Object connected on an input of the switcher.
Disconnect
A destination is disconnected when there is no link
with any source. This status is symbolized by a
fictive object that has to be assigned as a source
called « disconnected ».
7.3 STARTING
7.3.1 Power On
The software MatrixOp4 should be installed on
hard disk.
Switch Power on of the routing switcher, the PC
and the screen.
Start the system by clicking « matrixop4.exe », then
the switching program takes over and runs
automatically.
After an auto-test, the program is ready, and
positions itself on the page that has been previously
automatically protected.
It establishes the links, and transmits them to the
matrix.
The auto-test was designed to check the correct
functioning of the matrix.
7.3.1.1 SET-UP
When just installed, the software may be initialized.
The matrix may be linked. Setup request
automatically the size of the matrix.
If fault arises :
1) Check that the routing switcher is « power on »
2) Select another port
3) Check the link between PC and Matrix unit
with the RS-232 cable
4) The LED display of the routing switcher must
lit a switching to every transmission.
5) Check if there is evidence of connection
between the devices declared in the menus and
the real configurations of the matrix. Check
that there is not more numbers than the
physical capacity of the matrix.
Verify the whole matrix/PC and restart the
program.
7.3.2 STOPPING THE SYSTEM
Turn off of the power.
The switching off of power to the central unit (PC)
and its screen doesn’t alter the connection of the
matrix (as long as the matrix is powered).
Switching off power to the routing switcher will
cease all switching actions. When switching on the
matrix, it will keep its previous configuration.
MatrixOp4 can reset the matrix however with the
“initialization” command.
7.4 ASSIGNMENTS EDITOR
7.4.1 COMMAND : Assignments
To run this subroutine, click the assignment
command. This program establishes the name and
the state of the peripheral objects.
This is the only moment where the numbering of
the audio and video connectors is shown.
When opening of this program, this window
appears, as well as a schematic representation of
the routing switcher and of the peripheral objects.
This very simplified schematic is as a real wiring
map sheet.
Four layers can work simultaneously, and each one
can have a different size.
This list form can be managed with all the function
menu, as file/edit/view/audio levels/ matrix upload.

MATRIX ROUTING SWITCHER
7.4.1.1 Names and Connectors capture.
Click on the line of a source or destination object.
This window opens :
This window represents the state of an object.
Enter the name of the object, or select it in the list.
Each new name will be automatically added in the
list. This is easy to get it again for other object with
the same name in another column or layer.
If an object with the same name exist in the current
column, MatrixOp4 will ask you if you want to
remove the existing one.
Choose the number of the connector of your object
in each layer. This will be useful the find easily
your objects on the connexion board.
For example, name “camera2” for video player as
source, choose video “2” if BNC N°2 is used,
choose audio “5” if audio connector 5 is used for
this camera, etc…
7.4.1.2 Remote Control Panel programming.
For both remote control panels, 32 Touches or
LCD, it is possible to assign a function for each
touch. In the case of 32 touches panel, each touch is
materially represented on the picture, respectively
from 1 to 32. A second panel can follow up to 64, a
third to 96, and so on. In the case of LCD panel,
each touch is represented as a step of
incrementation, for source and destination.
The list of the steps is also available in the
combobox “Remote panel control”.
When the name and the connectors assignment is
defined, you can choose the number of the touch,
(or the step), you want to assign on your control
panel. Selecting a touch will automatically assign it
in the opened direction (source or destination). The
touch will take the colour, blue for input, red for
output, magenta for other special functions. The
number of the touch is not necessary the same as
the layers numbers. If no touch is selected, this
object (source or destination) will not be accessible
by the remote control panel. The OK button will
valid this window datas.
The remote control panels will be operational after
an assignments upload, described below.
7.4.1.3 Assignments Upload.
When the assignments are defined, you can upload
the datas to the EEPROM of the matrix for the
remote control panel to get autonomy and be
independent of the computer. Select the menu
“Matrix / Upload EEPROM”, and follow the
procedure. The upload takes about two minutes.
The control panels should not be used while
uploading.
7.5 MATRIX CONTROLLER
7.5.1 General Informations
The mains routine of the software MatrixOp4
consist to create some crosspoints between various
sources and destinations.
MatrixOp4 don’t use the numbers of the connectors
to the devices, but only the names of these devices.
The connections are directly made between the
sources and the destinations. MatrixOp4 calculates
each crosspoint, and returns the router, the code
containing the layers and the connectors numbers.
As a matter of fact, several connections can be
done with only one operation. The video, RGB,
audio and YC layers can be following, or separated.
7.5.2 The Switching Display
20
KRAMER
Electronics
MATRIX ROUTING SWITCHER
This mode of display is characterized by several
personal lines corresponding each one at a
destination, which is identified on the left side. On
the right side, the four sources that are connected
are shown, and can be changed.
7.5.2.1 Selecting and Switching
First, choose a destination by clicking on the line.
Then, a new window opens, with the list of
available sources in each layer :
In this window, choose in the separate layers list
that you want use, or in the common list, the
sources you need. The switching will be
automatically effective according the possibilities.
7.6 COPY BACK-UP
When the edition of the menu is finished, it is
important to make a copy. Save the file:
C:\Program Files\Matrixop4\*.agn
To save the switching part, the files have the
extension .cnx
Warning: the MatrixOp4 licence that you possess
works only with the delivered matrix. A copy of it
cannot work on an other matrix. The normal
